It looks like this is an upstreaming effort for code written against
DPDK v21.11.
There are unrelated / broken changes (probably due to some rebase issue).
Please fix at least what I quickly noticed:
- no version.map if unneeded,
- no touching of rte_config.h like disabling RTE_BACKTRACE,
- don't reintroduce renamed headers, like for example rte_cryptodev_pmd.h,
- don't remove "dma" device support in usertools/dpdk-devbind.py,
- don't introduce a hardware specific example,
Important: overall, this patch should be split in logical smaller
patches introducing feature one at a time.
And for next revisions, please version your patches, and register to
the dev@ mailing list and patchwork.

Along with the comments from David, one more high level comment.
Why do you need to have a separate example application?
Can you align with app/test/test_cryptodev.c and app/test/test_compressdev.c?

You can use RTE_DIM instead of defining your own macro.

No documentation added in the complete patchset.
Add cover letter.
Add release notes.
Also, it is not a good practice to enable compilation in the last patch.
Each of the patches should be getting compiled individually as well.
Do not add code which is not getting compiled/used in individual patches.

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+==================================================
+
+ZSDA documentation consists of three parts:
+
+* Details of the symmetric crypto services below.
+* Details of the :doc:`compression service <../compressdevs/zsda>`
+ in the compressdev drivers section.
+* Details of building the common ZSDA infrastructure and the PMDs to support the
+ above services. See :ref:`building_zsda` below.
+
+
+Symmetric Crypto Service on ZSDA
+-------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+Features
+~~~~~~~~
+
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
+
+Limitations
+~~~~~~~~~~~
+
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+--------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console

+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one symmetric cryptodev PMD and/or one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+ZSDA SYM crypto PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>cryptodev_zsda_autotest
+
+ZSDA compression PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>compressdev_autotest
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+==================================================
+
+ZSDA documentation consists of three parts:
+
+* Details of the symmetric crypto services below.
+* Details of the :doc:`compression service <../compressdevs/zsda>`
+ in the compressdev drivers section.
+* Details of building the common ZSDA infrastructure and the PMDs to support the
+ above services. See :ref:`building_zsda` below.
+
+
+Symmetric Crypto Service on ZSDA
+-------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+Features
+~~~~~~~~
+
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
+
+Limitations
+~~~~~~~~~~~
+
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+--------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+==================================================
+
+ZSDA documentation consists of three parts:
+
+* Details of the symmetric crypto services below.
+* Details of the :doc:`compression service <../compressdevs/zsda>`
+ in the compressdev drivers section.
+* Details of building the common ZSDA infrastructure and the PMDs to support the
+ above services. See :ref:`building_zsda` below.
+
+
+Symmetric Crypto Service on ZSDA
+-------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+Features
+~~~~~~~~
+
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
+
+Limitations
+~~~~~~~~~~~
+
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+--------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one symmetric cryptodev PMD and/or one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+ZSDA SYM crypto PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>cryptodev_zsda_autotest
+
+ZSDA compression PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>compressdev_autotest
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

Fix you editor settings, all files in git should end with a newline.
Did you build the docs after this? Build is failing here.
If you add a new feature it needs to be in default.ini as well.

There should not be a separate patch for documentation.
Add base doc in your base driver code patch.
And add subsequent features in documentation in the same patch as code.

The title of the patch suggest that it include device start and stop.
But it seems there is code related to configuration of queue as well.
Please move accordingly.

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+====================================================
+
+ZSDA documentation consists of three parts:
+
+* Details of the symmetric crypto services below.
+* Details of the :doc:`compression service <../compressdevs/zsda>`
+ in the compressdev drivers section.
+* Details of building the common ZSDA infrastructure and the PMDs to support the
+ above services. See :ref:`building_zsda` below.
+
+
+Symmetric Crypto Service on ZSDA
+--------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+Features
+~~~~~~~~
+
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
+
+Limitations
+~~~~~~~~~~~
+
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one symmetric cryptodev PMD and/or one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+ZSDA SYM crypto PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>cryptodev_zsda_autotest
+
+ZSDA compression PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>compressdev_autotest
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+====================================================
+
+ZSDA documentation consists of three parts:
+
+* Details of the symmetric crypto services below.
+* Details of the :doc:`compression service <../compressdevs/zsda>`
+ in the compressdev drivers section.
+* Details of building the common ZSDA infrastructure and the PMDs to support the
+ above services. See :ref:`building_zsda` below.
+
+
+Symmetric Crypto Service on ZSDA
+--------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+Features
+~~~~~~~~
+
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
+
+Limitations
+~~~~~~~~~~~
+
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one symmetric cryptodev PMD and/or one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing

+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

The patch provides a series of interfaces for managing
and controlling the configuration, start, stop,
resource management, etc. of crypto devices.
And the patches may contain compilation errors.
Because the patches are depended on the other patch.
Depends-on: series-cryptodev: add SM4-XTS algo and test cases

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+====================================================
+
+ZSDA documentation consists of three parts:
+
+* Details of the symmetric crypto services below.
+* Details of the :doc:`compression service <../compressdevs/zsda>`
+ in the compressdev drivers section.
+* Details of building the common ZSDA infrastructure and the PMDs to support the
+ above services. See :ref:`building_zsda` below.
+
+
+Symmetric Crypto Service on ZSDA
+--------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+Features
+~~~~~~~~
+
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
+
+Limitations
+~~~~~~~~~~~
+
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one symmetric cryptodev PMD and/or one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+ZSDA SYM crypto PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>cryptodev_zsda_autotest
+
+ZSDA compression PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>compressdev_autotest
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+====================================================
+
+ZSDA documentation consists of three parts:
+
+* Details of the symmetric crypto services below.
+* Details of the :doc:`compression service <../compressdevs/zsda>`
+ in the compressdev drivers section.
+* Details of building the common ZSDA infrastructure and the PMDs to support the
+ above services. See :ref:`building_zsda` below.
+
+
+Symmetric Crypto Service on ZSDA
+--------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+Features
+~~~~~~~~
+
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
+
+Limitations
+~~~~~~~~~~~
+
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one symmetric cryptodev PMD and/or one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+ZSDA SYM crypto PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>cryptodev_zsda_autotest
+
+ZSDA compression PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>compressdev_autotest
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

Hi maintainers:
Do we need to solve the error and warning?
We haven't found the detailed reason for the error and warning in the output log.
And we don't modified code about eal_flags_misc_autotes, cryptodev_sw_zuc_autotest or cryptodev_sw_snow3g_autotest,
which can be ensured in https://patches.dpdk.org/project/dpdk/cover/20241019110428.1970056-1-li.hanxiao@zte.com.cn/.
The error info:
| Fedora 38 (Clang) | FAIL |
34/113 DPDK:fast-tests / eal_flags_misc_autotest FAIL 1.93 s (killed by signal 11 SIGSEGV)
The warnging info:
No testlog script to copy
Thanks.

If the config/meson.build file is changed to re-enable some compiler warnings
that are being suppressed. It shows that this structure might be problematic.
This is not a show stopper. But it does indicate problems (especially on Arm where
unaligned access is more of a problem).

That means the void * value is not aligned etc.

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+====================================================
+
+ZSDA documentation consists of three parts:
+
+* Details of the symmetric crypto services below.
+* Details of the :doc:`compression service <../compressdevs/zsda>`
+ in the compressdev drivers section.
+* Details of building the common ZSDA infrastructure and the PMDs to support the
+ above services. See :ref:`building_zsda` below.
+
+
+Symmetric Crypto Service on ZSDA
+--------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+Features
+~~~~~~~~
+
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
+
+Limitations
+~~~~~~~~~~~
+
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one symmetric cryptodev PMD and/or one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+ZSDA SYM crypto PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>cryptodev_zsda_autotest
+
+ZSDA compression PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>compressdev_autotest
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+====================================================
+
+ZSDA documentation consists of three parts:
+
+* Details of the symmetric crypto services below.
+* Details of the :doc:`compression service <../compressdevs/zsda>`
+ in the compressdev drivers section.
+* Details of building the common ZSDA infrastructure and the PMDs to support the
+ above services. See :ref:`building_zsda` below.
+
+
+Symmetric Crypto Service on ZSDA
+--------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+Features
+~~~~~~~~
+
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
+
+Limitations
+~~~~~~~~~~~
+
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one symmetric cryptodev PMD and/or one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+ZSDA SYM crypto PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>cryptodev_zsda_autotest
+
+ZSDA compression PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>compressdev_autotest
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

Not sure why you used a pragma here and __rte_packed in all other cases.
Its ok, the effect is the same, but maybe better to be consistent.
Packed is not even needed here, the compiler will do the same layout
with or without packed in this case.
No need for a new version but you may want to look into it.

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+====================================================
+
+ZSDA documentation consists of three parts:
+
+* Details of the symmetric crypto services below.
+* Details of the :doc:`compression service <../compressdevs/zsda>`
+ in the compressdev drivers section.
+* Details of building the common ZSDA infrastructure and the PMDs to support the
+ above services. See :ref:`building_zsda` below.
+
+
+Symmetric Crypto Service on ZSDA
+--------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+Features
+~~~~~~~~
+
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
+
+Limitations
+~~~~~~~~~~~
+
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one symmetric cryptodev PMD and/or one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+ZSDA SYM crypto PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>cryptodev_zsda_autotest
+
+ZSDA compression PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>compressdev_autotest
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+=======================================================
+
+The ZSDA compression PMD provides poll mode compression & decompression driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+
+Features
+--------
+
+ZSDA compression PMD has support for:
+
+Compression/Decompression algorithm:
+
+ * DEFLATE - using Fixed and Dynamic Huffman encoding
+
+Checksum generation:
+
+ * CRC32, Adler32
+
+Huffman code type:
+
+* FIXED
+* DYNAMIC
+
+
+Limitations
+-----------
+
+* Compressdev level 0, no compression, is not supported.
+* No BSD support as BSD ZSDA kernel driver not available.
+* Stateful is not supported.
+
+
+Installation
+------------
+
+The ZSDA compression PMD is built by default with a standard DPDK build.
+
+It depends on a ZSDA kernel driver, see :ref:`building_zsda`.

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+====================================================
+
+ZSDA documentation consists of three parts:
+
+* Details of the symmetric crypto services below.
+* Details of the :doc:`compression service <../compressdevs/zsda>`
+ in the compressdev drivers section.
+* Details of building the common ZSDA infrastructure and the PMDs to support the
+ above services. See :ref:`building_zsda` below.
+
+
+Symmetric Crypto Service on ZSDA
+--------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+Features
+~~~~~~~~
+
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
+
+Limitations
+~~~~~~~~~~~
+
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one symmetric cryptodev PMD and/or one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+ZSDA SYM crypto PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>cryptodev_zsda_autotest
+
+ZSDA compression PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>compressdev_autotest
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

This patch should also have driver skeleton as mentioned in above patch.
In your case, you have a crypto and a compress driver together in a single patchset which is dependent on common code.
You can split this into crypto and compress documentation and add it in first patch of where these drivers are initialized.
First you can have the common code and then compress driver followed by crypto driver.
Update MAINTAINERS wherever a new folder/file is added.
So in your case the patches would be like
1. config: add zsda device number
2. common/zsda: configure pci_driver for zsda --
- This is your skeleton where probe and remove are there.
- Update MAINTAINERS for common/zsda and .ini .rst files added in this patch
- Here you can add common documentation
- also add .ini and .rst files without adding specific features.
3. common/zsda: add logging macros
4. common/zsda: add common functions
5. common/zsda: add functions to operate hardware queue
6. common/zsda: configure queue operation
7. common/zsda: configure the enqueue datapath
8. common/zsda: configure the dequeue datapath
9. compress/zsda: add compression algo match ---- update MAINTAINERS for compress/zsda and update .rst for general features.
10. compress/zsda: add treatment of compressdev cqe and chksum -> rephrase your title.
11. compress/zsda: add configuration of compressdev_ops -> rephrase
12. compress/zsda: add functions of compressdev create and destroy
- here your feature is complete for compression. You can update .ini file for the features supported.
- also update release notes for compressdev.
- update .rst file for testing/debugging.
13. crypto/zsda: introduce key expansion code ---- update MAINTAINERS for crypto/zsda
14. crypto/zsda: configure session -- update .rst file for general features.
15. crypto/zsda: add sym algo match
16. crypto/zsda: configure wqe of cryptodev
17. crypto/zsda: add treatment of cryptodev cqe
18. crypto/zsda: add capabilities of sym
- update features in .ini as per the capabilities.
19. crypto/zsda: add configuration of cryptodev_ops
20. crypto/zsda: add functions of cryptodev create and destroy
- update release notes for crypto driver.
- update .rst for testing/debugging
The .ini file features should be added in subsequent patches where the feature is added.
First patch is to make a skeleton of the driver and need not have complete documentation
Of something which is not yet there in that patch.
>
> This patch may contain compilation errors.
> Because the patch is depended on the other patch.
>
> Depends-on: series-cryptodev: add SM4-XTS algo and test cases
This patch is merged, so this can be removed.
Now, every patch should compile without any warnings.

You should add all these features in .ini file in the same patch as the feature is added.
In this patch just add the file with just HW accelerated =Y.
Rest all can be added where the feature is supported.

+
+Symmetric Crypto Service on ZSDA
+--------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:

+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one symmetric cryptodev PMD and/or one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

Features
~~~~~~~~
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
Limitations
~~~~~~~~~~~
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)

+Symmetric Crypto Service on ZSDA
+--------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+Features

+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one symmetric cryptodev PMD and/or one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

Features
~~~~~~~~
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
Limitations
~~~~~~~~~~~
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)

There was a previous modification suggestion to "update .rst for testing/debugging".
But I have no idea how to do this.
v18:
- add code in drivers/meson.build to compile zsda drivers.
- make every patch compile without any warnings or errors.
v17:
- fix some spelling errors
v16:
- resplit patches.
- complete documentation which is yet there in that patch.
- every patch should compile without any warnings or errors.
- delete unused comments.
v15:
- split to more patches.
v14:
- Uniform Byte Alignment.
v13:
- resolve some comiler warnings that are being suppressed.
v12:
- use RTE_LOG_LINE_PREFIX in logging macro.
- delete the check for null with rte_mempool_free.
- delete some unused initial values.
v11:
- use RTE_LOG_LINE in logging macro.
- fix some known bugs.
v10:
- delete new blank line at EOF
- Cleaning up some code in zsda_log.h
v9:
- add a new feature in default.ini.
- Re-split the patch according to the new PMD guidelines
https://patches.dpdk.org/project/dpdk/patch/20241006184
254.53499-1-nandinipersad361@gmail.com/
- Split SM4-XTS tests into a new series to releases.
- Separate out datapath(enqueue/dequeue) as a separate patch.
v8:
- fix some errors in cryptodevs/features/zsda.ini.
v7:
- add release notes and some documentations.
- add MAINTAINERS context in the patch where the file/folder is added.
- add files in meason.build which are included in the patch only.
- add a check for unsupported on Windows.
- notice the implicit cast in C.
- add cover letter.
- compile each of the patches individually.

+Symmetric Crypto Service on ZSDA
+--------------------------------
+
+The ZSDA symmetric crypto PMD provides poll mode crypto driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+Features
+~~~~~~~~
+
+

+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common ZSDA driver code which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+ZSDA SYM PMD has an external dependency on libcrypto, so is not built by default.
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda cryptodev symmetric crypto driver name is "crypto_zsda".
+* The zsda compressdev compress driver name is "compress_zsda".
+
+The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
+
+* Each zsda sym crypto device has a unique name, in format
+ "<pci bdf>", e.g. "0000:cc:00.3_zsda".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The zsda crypto device name is in the format of the worker parameter passed to the crypto scheduler.
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one symmetric cryptodev PMD and/or one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

Features
~~~~~~~~
+The ZSDA SYM PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_SM4_XTS``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SM3``
Limitations
~~~~~~~~~~~
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+* No BSD support as BSD ZSDA kernel driver not available.
+
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+ queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+ from the RX queue must be done from one thread, but enqueues and dequeues may be done
+ in different threads.)

I don’t see code for raw data path.
Even digest encrypted.
Protocol offload is also not there.
Update to feature list should be in same patch as the feature flag is added in code.
I see a lot of mismatches in the flags supported.
I see that scatter gather code is also added in later patch as well.

I asked multiple times to split the patches as per https://git.dpdk.org/dpdk/tree/doc/guides/contributing/new_driver.rst
In this patch you are
- configuring device
- setting capabilities
- configuring queues
- stats and device info
- session configuration
- scatter gather flags are also added here. Not sure if the feature is complete in this patch.
- even datapath is also added in this patch only.
This is a v18 patchset and still we have issues which were highlighted in initial versions.
Please review other crypto/compress PMDs which were submitted and merged in past
Before sending the next version.
You can use this as reference.
https://patches.dpdk.org/project/dpdk/list/?series=17483&state=%2A&archive=both
https://patches.dpdk.org/project/dpdk/list/?series=14865&state=%2A&archive=both
As these are some major changes to be done by today(RC2).
I would be deferring the patchset for next release.

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+=======================================================
+
+The ZSDA compression PMD provides poll mode compression & decompression driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+
+Features
+--------
+
+
+
+Limitations
+-----------
+
+* Compressdev level 0, no compression, is not supported.
+* No BSD support as BSD ZSDA kernel driver not available.
+* Stateful is not supported.
+
+
+Installation
+------------
+
+The ZSDA compression PMD is built by default with a standard DPDK build.
+
+It depends on a ZSDA kernel driver, see :ref:`building_zsda`.
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the compressdev APIs. The PMDs use common ZSDA driver code
+which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose
+ compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+ZSDA compression PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>compressdev_autotest
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

-There are 2 sets of trace available via the dynamic logging feature:
-
-* pmd.zsda.dp exposes trace on the data-path.
-* pmd.zsda.general exposes all other trace.

-pmd.zsda exposes both sets of traces.
-They can be enabled using the log-level option (where 8=maximum log level) on

- The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
- RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
- for meson build.
- Also the dynamic global log level overrides both sets of trace, so e.g. no

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+=======================================================
+
+The ZSDA compression PMD provides poll mode compression & decompression driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+
+Features
+--------
+
+
+
+Limitations
+-----------
+
+* Compressdev level 0, no compression, is not supported.
+* No BSD support as BSD ZSDA kernel driver not available.
+* Stateful is not supported.
+
+
+Installation
+------------
+
+The ZSDA compression PMD is built by default with a standard DPDK build.
+
+It depends on a ZSDA kernel driver, see :ref:`building_zsda`.
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the compressdev APIs. The PMDs use common ZSDA driver code
+which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+
+Ubuntu
+
+.. code-block:: console
+
+ apt install libssl-dev
+
+RHEL
+
+.. code-block:: console
+
+ dnf install openssl-devel
+
+The ZSDA compressdev PMD has no external dependencies, so is built by default.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose
+ compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+Testing
+~~~~~~~
+
+ZSDA compression PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>compressdev_autotest
+
+
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.zsda.dp exposes trace on the data-path.
+* pmd.zsda.general exposes all other trace.
+
+pmd.zsda exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
+
+ --log-level="pmd.zsda.general,8"
+ --log-level="pmd.zsda.dp,8"
+
+.. Note::
+
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ ZSDA trace would display in this case::
+
+ --log-level="pmd.zsda.general,8" --log-level="pmd.zsda,8"

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+=======================================================
+
+The ZSDA compression PMD provides poll mode compression & decompression driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+
+Features
+--------
+
+
+Installation
+------------
+
+The ZSDA compression PMD is built by default with a standard DPDK build.
+
+It depends on a ZSDA kernel driver, see :ref:`building_zsda`.
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the compressdev APIs. The PMDs use common ZSDA driver code
+which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose
+ compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+
+Testing
+~~~~~~~
+
+ZSDA compression PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>compressdev_autotest
+
+
+Debugging
+~~~~~~~~~
+
+ZSDA logging feature can be enabled using the log-level option (where 8=maximum
+log level) on the process cmdline, e.g. using any of the following::
+
+ --log-level="gen,8"

Hi Akhil:
I noticed that the state of patches is truned to 'Changes Requested', after turned to 'Deferred'.
So I modify and submit patches as soon as possible.
After modifying the patches, it was a bit late.
I noticed some errors, after submitting them. so I submitted v20 and v21 later.
I'm so sorry, if so many emails disturb you.
Besides, there is a misspelled error in comments of patch 11/13.
Is this a serious problem? If not, I will modify it in next series of patches.
Because I have only submitted one of four parts so far.
And If you think it's better to merged in next release. Well, It's ok.
Thanks and sorry,
Hanxiao Li

+ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver
+=======================================================
+
+The ZSDA compression PMD provides poll mode compression & decompression driver
+support for the following hardware accelerator devices:
+
+* ``ZTE Processing accelerators 1cf2``
+
+
+Features
+--------
+
+
+Installation
+------------
+
+The ZSDA compression PMD is built by default with a standard DPDK build.
+
+It depends on a ZSDA kernel driver, see :ref:`building_zsda`.
+
+
+.. _building_zsda:
+
+Building PMDs on ZSDA
+---------------------
+
+A ZSDA device can host multiple acceleration services:
+
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the compressdev APIs. The PMDs use common ZSDA driver code
+which manages the ZSDA PCI device.
+
+
+Configuring and Building the DPDK ZSDA PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Further information on configuring, building and installing DPDK is described
+:doc:`here <../linux_gsg/build_dpdk>`.
+
+.. _building_zsda_config:
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+These is the build configuration options affecting ZSDA, and its default values:
+
+.. code-block:: console
+
+ RTE_PMD_ZSDA_MAX_PCI_DEVICES=256
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The zsda compressdev driver name is "compress_zsda".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each zsda compression device has a unique name, in format
+ <pci bdf>, e.g. "0000:cc:00.3_zsda".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+
+Enable VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+
+Each ZSDA PF device exposes a number of VF devices. Each VF device can
+enable one compressdev PMD.
+
+These ZSDA PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
+
+.. Note::
+
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
+ Conversely one DPDK process can use one or more ZSDA VFs and can expose
+ compressdev instances on each of those VFs.
+
+
+The examples below are based on the 1cf2 device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:8050
+
+You should see output similar to::
+
+
+ cc:00.4 Processing accelerators: Device 1cf2:8050 (rev 01)
+ ce:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d0:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+ d2:00.3 Processing accelerators: Device 1cf2:8050 (rev 01)
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 31 > /sys/bus/pci/device/0000:cc:00.4/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:ce:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d0:00.3/sriov_numvfs
+ echo 31 > /sys/bus/pci/device/0000:d2:00.3/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:8051`` should
+list 124 VF devices available.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the vfio-pci driver`_.
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
+
+
+Binding the available VFs to the vfio-pci driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note:
+
+* Please note that due to security issues, the usage of older DPDK igb_uio
+ driver is not recommended. This document shows how to use the more secure
+ vfio-pci driver.
+
+Unbind the VFs from the stock driver so they can be bound to the vfio-pci driver.
+
+
+Bind to the vfio-pci driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
+e.g. for the 1cf2 device::
+
+ cd to the top-level DPDK directory
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py -b vfio-pci 0000:cc:01.4
+ usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
+
+
+Testing
+~~~~~~~
+
+ZSDA compression PMD can be tested by running the test application::
+
+ cd ./<build_dir>/app/test
+ ./dpdk-test -l1 -n1 -a <your zsda bdf>
+ RTE>>compressdev_autotest
+
+
+Debugging
+~~~~~~~~~
+
+ZSDA logging feature can be enabled using the log-level option (where 8=maximum
+log level) on the process cmdline, e.g. using any of the following::
+
+ --log-level="gen,8"
