This patch set adds initial driver support for OCTEON TX2 SoC.
OCTEON TX2 is an armv8.2 SoC with integrated HW based mempool, ethdev,
cryptodev, compressdev, and eventdev devices.
This patch set adds common driver and mempool device driver for OCTEON TX2 SoC.
There will be three more patch series in this release
to support ethdev, eventdev and cryptodev devices
More details about the OCTEON TX2 platform may found in
[PATCH 15/27] doc: add Marvell OCTEON TX2 platform guide
under doc/guides/platform/octeontx2.rst file.
This patches series also available at https://github.com/jerinjacobk/dpdk.git
for quick download and review.
# Note on check patch issues
1) The mailbox prototype is the same as Linux kernel.
https://elixir.bootlin.com/linux/latest/source/drivers/net/ethernet/marvell/octeontx2/af/mbox.h#L123
In order to keep the base code intact, mailbox prototype expressed as
macros with warnings
2) There are a few warnings from tooling about expected to add new
symbols in the EXPERIMENTAL
section. Since these API will be called only by octeontx2 client drivers
and prototype are not exported to the application, those warnings are
not relevant, Discussion at http://patches.dpdk.org/patch/53590/

Since some of those implementations are based on arm64 instructions added the stub to compile the code on non arm64 ISA. The non arm64 ISA stub is possible due to the fact that it is an integrated controller i.e runs only on Marvell HW.

In order to address mempool as standalone or integrated with ethdev/eventdev device, An intra device structure being introduced. When the _first_ ethdev/eventdev PCIe device or standalone mempool(NPA) devices get probed by the eal PCI subsystem, The NPA object(struct otx2_npa_lf) stored in otx2_dev base class. Once it is accomplished, the other consumer drivers like ethdev driver or eventdev driver use otx2_npa_* API to operate on shared NPA object. The similar concept followed for SSO object, Which needs to share between PCIe devices.

PF writes the message on mapped mailbox region followed by writing the mailbox doorbell register. Upon receiving, the mailbox request in AF(In Linux kernel), It processes the messages and update the counter memory and update the AF mbox doorbell register. That would trigger a VFIO interrupt to userspace and otx2_process_msgs() will handle it.

HW can support up to 1M mempools, Since each mempool costs set of HW resources, the max_pools devargs parameter is being introduced to configure the number of mempools required for the application. For example: -w 0002:02:00.0,max_pools=512 With the above configuration, the driver will set up only 512 mempools for the given application to save HW resources.

OCTEON TX2 is an armv8.2 SoC with integrated HW based mempool, ethdev, cryptodev, compressdev, and eventdev devices. This patch set adds common driver and mempool device driver for OCTEON TX2 SoC. There will be three more patch series in this release to support ethdev, eventdev and cryptodev devices More details about the OCTEON TX2 platform may found in [PATCH 15/27] doc: add Marvell OCTEON TX2 platform guide under doc/guides/platform/octeontx2.rst file. This patches series also available at https://github.com/jerinjacobk/dpdk.git for quick download and review. # Note on check patch issues 1) The mailbox prototype is the same as Linux kernel. https://elixir.bootlin.com/linux/latest/source/drivers/net/ethernet/marvell/octeontx2/af/mbox.h#L123 In order to keep the base code intact, mailbox prototype expressed as macros with warnings 2) There are a few warnings from tooling about expected to add new symbols in the EXPERIMENTAL section. Since these API will be called only by octeontx2 client drivers and prototype are not exported to the application, those warnings are not relevant, Discussion at http://patches.dpdk.org/patch/53590/ v2: 1) Added CONFIG_RTE_MAX_VFIO_GROUPS for octeontx2 config in patch 1 2) Rebased to master to accommodate latest rename like ETHER_ADDR_LEN to RTE_ETHER_ADDR_LEN 3) Added pmd.raw.octeontx2.dpi log

Since some of those implementations are based on arm64 instructions added the stub to compile the code on non arm64 ISA. The non arm64 ISA stub is possible due to the fact that it is an integrated controller i.e runs only on Marvell HW.

In order to address mempool as standalone or integrated with ethdev/eventdev device, An intra device structure being introduced. When the _first_ ethdev/eventdev PCIe device or standalone mempool(NPA) devices get probed by the eal PCI subsystem, The NPA object(struct otx2_npa_lf) stored in otx2_dev base class. Once it is accomplished, the other consumer drivers like ethdev driver or eventdev driver use otx2_npa_* API to operate on shared NPA object.

PF writes the message on mapped mailbox region followed by writing the mailbox doorbell register. Upon receiving, the mailbox request in AF(In Linux kernel), It processes the messages and update the counter memory and update the AF mbox doorbell register. That would trigger a VFIO interrupt to userspace and otx2_process_msgs() will handle it.

For example, + Ubuntu 15.10 (Wily) or 16.04 LTS (Xenial) userland which can be obtained + from `<http://cdimage.ubuntu.com/ubuntu-base/releases/16.04/release/ubuntu-base-16.04.1-base-arm64.tar.gz>`_. + + Alternatively, the Marvell SDK provides the buildroot based root filesystem. + The SDK includes all the above prerequisites necessary to bring up the OCTEON TX2 board. + +- Follow the DPDK :doc:`../linux_gsg/index` to setup the basic DPDK environment. + + +Debugging Options +----------------- + +.. _table_octeontx2_common_debug_options: + +.. table:: OCTEON TX2 common debug options + + +---+------------+-------------------------------------------------------+ + | # | Component | EAL log command | + +===+============+=======================================================+ + | 1 | Common | --log-level='pmd\.octeontx2\.base,8' | + +---+------------+-------------------------------------------------------+ + | 2 | Mailbox | --log-level='pmd\.octeontx2\.mbox,8' | + +---+------------+-------------------------------------------------------+ + +Debugfs support +~~~~~~~~~~~~~~~ + +The **OCTEON TX2 Linux kernel driver** provides support to dump RVU blocks +context or stats using debugfs. + +Enable ``debugfs`` by: + +1.

HW can support up to 1M mempools, Since each mempool costs set of HW resources, the max_pools devargs parameter is being introduced to configure the number of mempools required for the application. For example: -w 0002:02:00.0,max_pools=512 With the above configuration, the driver will set up only 512 mempools for the given application to save HW resources.

OCTEON TX2 is an armv8.2 SoC with integrated HW based mempool, ethdev, cryptodev, compressdev, and eventdev devices. This patch set adds common driver and mempool device driver for OCTEON TX2 SoC. There will be three more patch series in this release to support ethdev, eventdev and cryptodev devices More details about the OCTEON TX2 platform may found in [PATCH 15/27] doc: add Marvell OCTEON TX2 platform guide under doc/guides/platform/octeontx2.rst file. This patches series also available at https://github.com/jerinjacobk/dpdk.git for quick download and review. # Note on check patch issues 1) The mailbox prototype is the same as Linux kernel. https://elixir.bootlin.com/linux/latest/source/drivers/net/ethernet/marvell/octeontx2/af/mbox.h#L123 In order to keep the base code intact, mailbox prototype expressed as macros with warnings 2) There are a few warnings from tooling about expected to add new symbols in the EXPERIMENTAL section. Since these API will be called only by octeontx2 client drivers and prototype are not exported to the application, those warnings are not relevant, Discussion at http://patches.dpdk.org/patch/53590/ v3: 1) Replace the reference to v19.08 from v19.05 2) remove rte_panic from driver code 3) rebase to dpdk.org master(as of 17-June) v2: 1) Added CONFIG_RTE_MAX_VFIO_GROUPS for octeontx2 config in patch 1 2) Rebased to master to accommodate latest rename like ETHER_ADDR_LEN to RTE_ETHER_ADDR_LEN 3) Added pmd.raw.octeontx2.dpi log message in patch 5 4) Update platform guide with debugfs documentation in patch 15 5) Fix arm64 build issue with patch 25(Aaron Conole) "mempool/octeontx2: add optimized dequeue operation for arm64" Cc: Thomas Monjalon <thomas@monjalon.net> Jerin Jacob

Since some of those implementations are based on arm64 instructions added the stub to compile the code on non arm64 ISA. The non arm64 ISA stub is possible due to the fact that it is an integrated controller i.e runs only on Marvell HW.

Each RVU device has a dedicated 64KB mailbox region shared with its peer for communication. RVU AF has a separate mailbox region shared with each of RVU PFs and an RVU PF has a separate region shared with each of it's VF.

In order to address mempool as standalone or integrated with ethdev/eventdev device, An intra device structure being introduced. When the _first_ ethdev/eventdev PCIe device or standalone mempool(NPA) devices get probed by the eal PCI subsystem, The NPA object(struct otx2_npa_lf) stored in otx2_dev base class. Once it is accomplished, the other consumer drivers like ethdev driver or eventdev driver use otx2_npa_* API to operate on shared NPA object. The similar concept followed for SSO object, Which needs to share between PCIe devices.

PF writes the message on mapped mailbox region followed by writing the mailbox doorbell register. Upon receiving, the mailbox request in AF(In Linux kernel), It processes the messages and update the counter memory and update the AF mbox doorbell register. That would trigger a VFIO interrupt to userspace and otx2_process_msgs() will handle it.

For example, + Ubuntu 15.10 (Wily) or 16.04 LTS (Xenial) userland which can be obtained + from `<http://cdimage.ubuntu.com/ubuntu-base/releases/16.04/release/ubuntu-base-16.04.1-base-arm64.tar.gz>`_. + + Alternatively, the Marvell SDK provides the buildroot based root filesystem. + The SDK includes all the above prerequisites necessary to bring up the OCTEON TX2 board. + +- Follow the DPDK :doc:`../linux_gsg/index` to setup the basic DPDK environment. + + +Debugging Options +----------------- + +.. _table_octeontx2_common_debug_options: + +.. table:: OCTEON TX2 common debug options + + +---+------------+-------------------------------------------------------+ + | # | Component | EAL log command | + +===+============+=======================================================+ + | 1 | Common | --log-level='pmd\.octeontx2\.base,8' | + +---+------------+-------------------------------------------------------+ + | 2 | Mailbox | --log-level='pmd\.octeontx2\.mbox,8' | + +---+------------+-------------------------------------------------------+ + +Debugfs support +~~~~~~~~~~~~~~~ + +The **OCTEON TX2 Linux kernel driver** provides support to dump RVU blocks +context or stats using debugfs. + +Enable ``debugfs`` by: + +1.

It makes sense to document this - it isn't apparent that it is needed. It would be good to put a comment just before that explains it, preferably with the compilers that aren't behaving.

OCTEON TX2 is an armv8.2 SoC with integrated HW based mempool, ethdev, cryptodev, compressdev, and eventdev devices. This patch set adds common driver and mempool device driver for OCTEON TX2 SoC. There will be three more patch series in this release to support ethdev, eventdev and cryptodev devices More details about the OCTEON TX2 platform may found in [PATCH 15/27] doc: add Marvell OCTEON TX2 platform guide under doc/guides/platform/octeontx2.rst file. This patches series also available at https://github.com/jerinjacobk/dpdk.git for quick download and review. # Note on check patch issues 1) The mailbox prototype is the same as Linux kernel. https://elixir.bootlin.com/linux/latest/source/drivers/net/ethernet/marvell/octeontx2/af/mbox.h#L123 In order to keep the base code intact, mailbox prototype expressed as macros with warnings 2) There are a few warnings from tooling about expected to add new symbols in the EXPERIMENTAL section. Since these API will be called only by octeontx2 client drivers and prototype are not exported to the application, those warnings are not relevant, Discussion at http://patches.dpdk.org/patch/53590/ v4: 1) Add comments for O3 attribue flag (Aaron Conole) in "mempool/octeontx2: add optimized dequeue operation for arm64" patch 2) Update "common/octeontx2: add mbox request and response definition" to reflect latest mbox defintions 3) rebase to dpdk.org master(as of 22-June) v3: 1) Replace the reference to v19.08 from v19.05 2) remove rte_panic from driver code 3) rebase to dpdk.org master(as of 17-June) v2: 1) Added CONFIG_RTE_MAX_VFIO_GROUPS for octeontx2 config in patch 1 2) Rebased to master to accommodate latest rename like ETHER_ADDR_LEN to RTE_ETHER_ADDR_LEN 3) Added pmd.raw.octeontx2.dpi log message in patch 5 4) Update platform guide with debugfs documentation in patch 15 5) Fix arm64 build issue with patch 25(Aaron Conole) "mempool/octeontx2: add optimized

This patch adds skeleton otx2_mbox.c file to make sure all header files are intact, subsequent patches add content to otx2_mbox.c This patch also updates CONFIG_RTE_MAX_VFIO_GROUPS value to 128 as the system can have up to 128 PFs/VFs. For octeontx2 meson build target, CONFIG_RTE_MAX_VFIO_GROUPS defined as 128 so no additional changes required.

Since some of those implementations are based on arm64 instructions added the stub to compile the code on non arm64 ISA. The non arm64 ISA stub is possible due to the fact that it is an integrated controller i.e runs only on Marvell HW.

Each RVU device has a dedicated 64KB mailbox region shared with its peer for communication. RVU AF has a separate mailbox region shared with each of RVU PFs and an RVU PF has a separate region shared with each of it's VF.

In order to address mempool as standalone or integrated with ethdev/eventdev device, An intra device structure being introduced. When the _first_ ethdev/eventdev PCIe device or standalone mempool(NPA) devices get probed by the eal PCI subsystem, The NPA object(struct otx2_npa_lf) stored in otx2_dev base class. Once it is accomplished, the other consumer drivers like ethdev driver or eventdev driver use otx2_npa_* API to operate on shared NPA object. The similar concept followed for SSO object, Which needs to share between PCIe devices.

PF writes the message on mapped mailbox region followed by writing the mailbox doorbell register. Upon receiving, the mailbox request in AF(In Linux kernel), It processes the messages and update the counter memory and update the AF mbox doorbell register. That would trigger a VFIO interrupt to userspace and otx2_process_msgs() will handle it.

For example, + Ubuntu 15.10 (Wily) or 16.04 LTS (Xenial) userland which can be obtained + from `<http://cdimage.ubuntu.com/ubuntu-base/releases/16.04/release/ubuntu-base-16.04.1-base-arm64.tar.gz>`_. + + Alternatively, the Marvell SDK provides the buildroot based root filesystem. + The SDK includes all the above prerequisites necessary to bring up the OCTEON TX2 board. + +- Follow the DPDK :doc:`../linux_gsg/index` to setup the basic DPDK environment. + + +Debugging Options +----------------- + +.. _table_octeontx2_common_debug_options: + +.. table:: OCTEON TX2 common debug options + + +---+------------+-------------------------------------------------------+ + | # | Component | EAL log command | + +===+============+=======================================================+ + | 1 | Common | --log-level='pmd\.octeontx2\.base,8' | + +---+------------+-------------------------------------------------------+ + | 2 | Mailbox | --log-level='pmd\.octeontx2\.mbox,8' | + +---+------------+-------------------------------------------------------+ + +Debugfs support +~~~~~~~~~~~~~~~ + +The **OCTEON TX2 Linux kernel driver** provides support to dump RVU blocks +context or stats using debugfs. + +Enable ``debugfs`` by: + +1.

HW can support up to 1M mempools, Since each mempool costs set of HW resources, the max_pools devargs parameter is being introduced to configure the number of mempools required for the application. For example: -w 0002:02:00.0,max_pools=512 With the above configuration, the driver will set up only 512 mempools for the given application to save HW resources.
