This series adds initial support for baseband PHY available on SOCs
belonging to Fusion family. BPHY is a hardware block comprising
accelerators and DSPs specifically tailored for 5G/LTE usecases.

This series introduces two rawdev PMDs along with low level common code.

CGX/RPM PMD allows one to configure Ethernet I/O interfaces attached to
BPHY via standard enqueue/dequeue operations.

BPHY PMD provides an out-of-band access to PCI device BARs and a set of
experimental APIs allowing one to setup custom IRQs handlers. This
functionality is backed by kernel module using ioctl() mechanism.

Messages can be exchanged between userspace software and firmware
via set of two dedicated registers, namely scratch1 and scratch0.

scratch1 acts as a command register i.e message is sent to firmware,
while scratch0 holds response to previously sent message.

+Marvell CNXK BPHY Driver
+==========================================
+
+CN10K/CN9K Fusion product families offer an internal BPHY unit which provides
+set of hardware accelerators for performing baseband related operations. Connectivity
+to the outside world happens through a block called RFOE which is backed by
+ethernet I/O block called CGX or RPM (depending on the chip version). RFOE
+stands for Radio Frequency Over Ethernet and provides support for
+IEEE 1904.3 (RoE) standard.
+
+Features
+--------
+
+The BPHY CGX/RPM implements following features in the rawdev API:
+
+- Access to BPHY CGX/RPM via set of predefined messages.
+
+Device Setup
+------------
+
+The BPHY CGX/RPM  devices will need to be bound to a user-space IO driver for
+use. The script ``dpdk-devbind.py`` script included with DPDK can be used to
+view the state of the devices and to bind them to a suitable DPDK-supported
+kernel driver. When querying the status of the devices, they will appear under
+the category of "Misc (rawdev) devices", i.e. the command
+``dpdk-devbind.py --status-dev misc`` can be used to see the state of those
+devices alone.
+
+To perform data transfer use standard ``rte_rawdev_enqueue_buffers()`` and
+``rte_rawdev_dequeue_buffers()`` APIs. Not all messages produce sensible
+responses hence dequeueing is not always necessary.
+
+Self test
+---------
+
+On EAL initialization, BPHY CGX/RPM devices will be probed and populated into
+the raw devices. The rawdev ID of the device can be obtained using invocation
+of ``rte_rawdev_get_dev_id("NAME:x")`` from the test application, where:
+
+- NAME is the desired subsystem: use "BPHY_CGX" for
+  RFOE module,
+- x is the device's bus id specified in "bus:device.func" (BDF) format.
+
+Use this identifier for further rawdev function calls.
+
+The driver's selftest rawdev API can be used to verify the BPHY CGX/RPM
+functionality.

Add support for interrupt initialization and cleanup. Internally
interrupt initialization performs low level setup that allows
custom interrupt handler registration later on.

Interrupt initialization and cleanup are related hence they
are in the same patch.

Proabably we can tell name or class ID to understand what to bind from

Also, you can mention that This patch adds support for exposing the IO
and system aspects
of the device and not anything related to 5G/LTE baseband protocol processing.


Other than the minor review comments which I sent earlier.

I think, We need improvement in the documentation area Where

1) Need to share the API usage model as it is raw dev API.
See example as
http://doc.dpdk.org/guides/rawdevs/ioat.html#using-ioat-rawdev-devices

2) Move usage doc update move to specific patch where it adding the code.

This series adds initial support for baseband PHY available on SOCs
belonging to Fusion family. BPHY is a hardware block comprising
accelerators and DSPs specifically tailored for 5G/LTE inline usecases.

This series introduces two rawdev PMDs along with low level common code.

CGX/RPM PMD allows one to configure Ethernet I/O interfaces attached to
BPHY via standard enqueue/dequeue operations.

BPHY PMD provides an out-of-band access to PCI device BARs and a set of
experimental APIs allowing one to setup custom IRQs handlers. This
functionality is backed by kernel module using ioctl() mechanism. Series
has nothing to do with 5G/LTE baseband protocol processing.

v2:
- change some errors to more relevant ones (-EINVAL/-ENODEV)
- fix MAINTAINERS styling issues
- fix dpdk-devbind.py
- fix meson.build styling issues
- fix warning related to possibly uninitialized scr0 variable
- fix warning releated to unused function
- improve documentation
- improve enums items naming
- spread documentation across relevant patches

Messages can be exchanged between userspace software and firmware
via set of two dedicated registers, namely scratch1 and scratch0.

scratch1 acts as a command register i.e message is sent to firmware,
while scratch0 holds response to previously sent message.

Add baseband phy cgx/rpm skeleton driver which merely probes a matching
device. CGX/RPM are Ethernet MACs hardwired to baseband subsystem.

+Marvell CNXK BPHY Driver
+========================
+
+CN10K/CN9K Fusion product families offer an internal BPHY unit which provides
+set of hardware accelerators for performing baseband related operations.
+Connectivity to the outside world happens through a block called RFOE which is
+backed by ethernet I/O block called CGX or RPM (depending on the chip version).
+RFOE stands for Radio Frequency Over Ethernet and provides support for
+IEEE 1904.3 (RoE) standard.
+
+Device Setup
+------------
+
+The BPHY CGX/RPM devices will need to be bound to a user-space IO driver for
+use. The script ``dpdk-devbind.py`` script included with DPDK can be used to
+view the state of the devices and to bind them to a suitable DPDK-supported
+kernel driver. When querying the status of the devices, they will appear under
+the category of "Misc (rawdev) devices", i.e. the command
+``dpdk-devbind.py --status-dev misc`` can be used to see the state of those
+devices alone.

@@ -25,3 +32,64 @@ devices alone.
 Before performing actual data transfer one needs to first retrieve number of
 available queues with ``rte_rawdev_queue_count()`` and capacity of each
 using ``rte_rawdev_queue_conf_get()``.
+
+To perform data transfer use standard ``rte_rawdev_enqueue_buffers()`` and
+``rte_rawdev_dequeue_buffers()`` APIs. Not all messages produce sensible
+responses hence dequeueing is not always necessary.
+
+BPHY CGX/RPM PMD accepts ``struct cnxk_bphy_cgx_msg`` messages which differ by type and payload.
+Message types along with description are listed below.
+
+Get link information
+~~~~~~~~~~~~~~~~~~~~
+
+Message is used to get information about link state.
+
+Message must have type set to ``CNXK_BPHY_CGX_MSG_TYPE_GET_LINKINFO``. In response one will
+get message containing payload i.e ``struct cnxk_bphy_cgx_msg_link_info`` filled with information
+about current link state.
+
+Change internal loopback state
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Message is used to enable or disable internal loopback.
+
+Message must have type set to ``CNXK_BPHY_CGX_MSG_TYPE_INTLBK_ENABLE`` or
+``CNXK_BPHY_CGX_MSG_TYPE_INTLBK_DISABLE``. Former will activate internal loobback while the latter
+will do the opposite.
+
+Change PTP RX state
+~~~~~~~~~~~~~~~~~~~
+
+Message is used to enable or disable PTP mode.
+
+Message must have type set to ``CNXK_BPHY_CGX_MSG_TYPE_PTP_RX_ENABLE`` or
+``CNXK_BPHY_CGX_MSG_TYPE_PTP_RX_DISABLE``. Former will enable PTP while the latter will do the
+opposite.
+
+Set link mode
+~~~~~~~~~~~~~
+
+Message is used to change link mode.
+
+Message must have type set to ``CNXK_BPHY_CGX_MSG_TYPE_SET_LINK_MODE``. Prior to sending actual
+message payload i.e ``struct cnxk_bphy_cgx_msg_link_mode`` needs to be filled with relevant
+information.
+
+Change link state
+~~~~~~~~~~~~~~~~~
+
+Message is used to set link up or down.
+
+Message must have type set to ``CNXK_BPHY_CGX_MSG_TYPE_SET_LINK_STATE``. Prior to sending actual
+message payload i.e ``struct cnxk_bphy_cgx_msg_set_link_state`` needs to be filled with relevant
+information.
+
+Start or stop RX/TX
+~~~~~~~~~~~~~~~~~~~
+
+Message is used to start or stop accepting traffic.
+
+Message must have type set to ``CNXK_BPHY_CGX_MSG_TYPE_START_RXTX`` or
+``CNXK_BPHY_CGX_MSG_TYPE_STOP_RXTX``. Former will enable traffic while the latter will
+do the opposite.

Add baseband phy skeleton driver. Baseband phy is a hardware subsystem
accelerating 5G/LTE related tasks. Note this driver isn't involved into
any sort baseband protocol processing. Instead it just provides means
for configuring hardware.

Add support for interrupt initialization and cleanup. Internally
interrupt initialization performs low level setup that allows
custom interrupt handler registration later on.

Interrupt initialization and cleanup are related hence they
are in the same patch.

This series looks good to me.
Feel free to add my reviewed by for the series after fix the following

1) Typo

  Cc: thomas, dev, Tomasz Duszynski

This series adds initial support for baseband PHY available on SOCs
belonging to Fusion family. BPHY is a hardware block comprising
accelerators and DSPs specifically tailored for 5G/LTE inline usecases.

This series introduces two rawdev PMDs along with low level common code.

CGX/RPM PMD allows one to configure Ethernet I/O interfaces attached to
BPHY via standard enqueue/dequeue operations.

BPHY PMD provides an out-of-band access to PCI device BARs and a set of
experimental APIs allowing one to setup custom IRQs handlers. This
functionality is backed by kernel module using ioctl() mechanism. Series
has nothing to do with 5G/LTE baseband protocol processing.

v3:
- append pmd to list of cnxk drivers (cnxk.rst)
- fix typo
- fix line length so it is under 80 characters
- shorten release notes

v2:
- change some errors to more relevant ones (-EINVAL/-ENODEV)
- fix MAINTAINERS styling issues
- fix dpdk-devbind.py
- fix meson.build styling issues
- fix warning related to possibly uninitialized scr0 variable
- fix warning related to unused function
- improve documentation
- improve enums items naming
- spread documentation across relevant patches

Initialization and cleanup are related hence are in the same patch.

Messages can be exchanged between userspace software and firmware
via set of two dedicated registers, namely scratch1 and scratch0.

scratch1 acts as a command register i.e message is sent to firmware,
while scratch0 holds response to previously sent message.

+Marvell CNXK BPHY Driver
+========================
+
+CN10K/CN9K Fusion product families offer an internal BPHY unit which provides
+set of hardware accelerators for performing baseband related operations.
+Connectivity to the outside world happens through a block called RFOE which is
+backed by ethernet I/O block called CGX or RPM (depending on the chip version).
+RFOE stands for Radio Frequency Over Ethernet and provides support for
+IEEE 1904.3 (RoE) standard.
+
+Device Setup
+------------
+
+The BPHY CGX/RPM devices will need to be bound to a user-space IO driver for
+use. The script ``dpdk-devbind.py`` script included with DPDK can be used to
+view the state of the devices and to bind them to a suitable DPDK-supported
+kernel driver. When querying the status of the devices, they will appear under
+the category of "Misc (rawdev) devices", i.e. the command
+``dpdk-devbind.py --status-dev misc`` can be used to see the state of those
+devices alone.

 Before performing actual data transfer one needs to first retrieve number of
 available queues with ``rte_rawdev_queue_count()`` and capacity of each
 using ``rte_rawdev_queue_conf_get()``.
+
+To perform data transfer use standard ``rte_rawdev_enqueue_buffers()`` and

+
+BPHY CGX/RPM PMD accepts ``struct cnxk_bphy_cgx_msg`` messages which differ by type and payload.
+Message types along with description are listed below.
+
+Get link information
+~~~~~~~~~~~~~~~~~~~~
+
+Message is used to get information about link state.
+
+Message must have type set to ``CNXK_BPHY_CGX_MSG_TYPE_GET_LINKINFO``. In response one will
+get message containing payload i.e ``struct cnxk_bphy_cgx_msg_link_info`` filled with information
+about current link state.
+
+Change internal loopback state
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Message is used to enable or disable internal loopback.
+
+Message must have type set to ``CNXK_BPHY_CGX_MSG_TYPE_INTLBK_ENABLE`` or
+``CNXK_BPHY_CGX_MSG_TYPE_INTLBK_DISABLE``. Former will activate internal loopback while the latter
+will do the opposite.

+
+Message must have type set to ``CNXK_BPHY_CGX_MSG_TYPE_PTP_RX_ENABLE`` or
+``CNXK_BPHY_CGX_MSG_TYPE_PTP_RX_DISABLE``. Former will enable PTP while the latter will do the
+opposite.
+
+Set link mode
+~~~~~~~~~~~~~
+
+Message is used to change link mode.
+
+Message must have type set to ``CNXK_BPHY_CGX_MSG_TYPE_SET_LINK_MODE``. Prior to sending actual
+message payload i.e ``struct cnxk_bphy_cgx_msg_link_mode`` needs to be filled with relevant
+information.
+
+Change link state
+~~~~~~~~~~~~~~~~~
+
+Message is used to set link up or down.
+
+Message must have type set to ``CNXK_BPHY_CGX_MSG_TYPE_SET_LINK_STATE``. Prior to sending actual
+message payload i.e ``struct cnxk_bphy_cgx_msg_set_link_state`` needs to be filled with relevant

+
+Start or stop RX/TX
+~~~~~~~~~~~~~~~~~~~
+
+Message is used to start or stop accepting traffic.
+
+Message must have type set to ``CNXK_BPHY_CGX_MSG_TYPE_START_RXTX`` or
+``CNXK_BPHY_CGX_MSG_TYPE_STOP_RXTX``. Former will enable traffic while the latter will
+do the opposite.

+Self test
+---------
+
+On EAL initialization, BPHY CGX/RPM devices will be probed and populated into
+the raw devices. The rawdev ID of the device can be obtained using invocation
+of ``rte_rawdev_get_dev_id("NAME:x")`` from the test application, where:
+
+- NAME is the desired subsystem: use "BPHY_CGX" for
+  RFOE module,
+- x is the device's bus id specified in "bus:device.func" (BDF) format.
+
+Use this identifier for further rawdev function calls.
+
+The driver's selftest rawdev API can be used to verify the BPHY CGX/RPM
+functionality.

Add baseband phy skeleton driver. Baseband phy is a hardware subsystem
accelerating 5G/LTE related tasks. Note this driver isn't involved into
any sort baseband protocol processing. Instead it just provides means
for configuring hardware.

Add support for interrupt initialization and cleanup. Internally
interrupt initialization performs low level setup that allows
custom interrupt handler registration later on.

Interrupt initialization and cleanup are related hence they
are in the same patch.
