PFx and PFx-VF0 bound to Linux netdev driver. +2. PFx-VF1 ethdev driver bound to the first DPDK application. +3. PFy ethdev driver, PFy-VF0 ethdev driver, PFz eventdev driver, PFm-VF0 cryptodev driver bound to the second DPDK application. + +LBK HW Access +------------- + +Loopback HW Unit (LBK) receives packets from NIX-RX and sends packets back to NIX-TX. +The loopback block has N channels and contains data buffering that is shared across +all channels. The LBK HW Unit is abstracted using ethdev subsystem, Where PF0's +VFs are exposed as ethdev device and odd-even pairs of VFs are tied together, +that is, packets sent on odd VF end up received on even VF and vice versa. +This would enable HW accelerated means of communication between two domains +where even VF bound to the first domain and odd VF bound to the second domain. + +Typical application usage models are, + +#. Communication between the Linux kernel and DPDK application. +#. Exception path to Linux kernel from DPDK application as SW ``KNI`` replacement. +#. Communication between two different DPDK applications. + +SDP interface +------------- + +System DPI Packet Interface unit(SDP) provides PCIe endpoint support for remote host +to DMA packets into and out of cnxk SoC. SDP interface comes in to live only when +cnxk SoC is connected in PCIe endpoint mode. It can be used to send/receive +packets to/from remote host machine using input/output queue pairs exposed to it. +SDP interface receives input packets from remote host from NIX-RX and sends packets +to remote host using NIX-TX. Remote host machine need to use corresponding driver +(kernel/user mode) to communicate with SDP interface on cnxk SoC. SDP supports +single PCIe SRIOV physical function(PF) and multiple virtual functions(VF's). Users +can bind PF or VF to use SDP interface and it will be enumerated as ethdev ports. + +The primary use case for SDP is to enable the smart NIC use case. Typical usage models are, + +#. Communication channel between remote host and cnxk SoC over PCIe. +#. Transfer packets received from network interface to remote host over PCIe and + vice-versa. + +cnxk packet flow +---------------------- + +The :numref:`figure_cnxk_packet_flow_hw_accelerators` diagram depicts +the packet flow on cnxk SoC in conjunction with use of various HW accelerators. + +.. _figure_cnxk_packet_flow_hw_accelerators: + +.. figure:: img/cnxk_packet_flow_hw_accelerators.* + + cnxk packet flow in conjunction with use of HW accelerators + +HW Offload Drivers +------------------ + +This section lists dataplane H/W block(s) available in cnxk SoC. + +Procedure to Setup Platform +--------------------------- + +There are three main prerequisites for setting up DPDK on cnxk +compatible board: + +1. **RVU AF Linux kernel driver** + + The dependent kernel drivers can be obtained from the + `kernel.org `_. + + Alternatively, the Marvell SDK also provides the required kernel drivers. + + Linux kernel should be configured with the following features enabled: + +.. code-block:: console + + # 64K pages enabled for better performance + CONFIG_ARM64_64K_PAGES=y + CONFIG_ARM64_VA_BITS_48=y + # huge pages support enabled + CONFIG_HUGETLBFS=y + CONFIG_HUGETLB_PAGE=y + # VFIO enabled with TYPE1 IOMMU at minimum + CONFIG_VFIO_IOMMU_TYPE1=y + CONFIG_VFIO_VIRQFD=y + CONFIG_VFIO=y + CONFIG_VFIO_NOIOMMU=y + CONFIG_VFIO_PCI=y + CONFIG_VFIO_PCI_MMAP=y + # SMMUv3 driver + CONFIG_ARM_SMMU_V3=y + # ARMv8.1 LSE atomics + CONFIG_ARM64_LSE_ATOMICS=y + # OCTEONTX2 drivers + CONFIG_OCTEONTX2_MBOX=y + CONFIG_OCTEONTX2_AF=y + # Enable if netdev PF driver required + CONFIG_OCTEONTX2_PF=y + # Enable if netdev VF driver required + CONFIG_OCTEONTX2_VF=y + CONFIG_CRYPTO_DEV_OCTEONTX2_CPT=y + # Enable if OCTEONTX2 DMA PF driver required + CONFIG_OCTEONTX2_DPI_PF=n + +2. **ARM64 Linux Tool Chain** + + For example, the *aarch64* Linaro Toolchain, which can be obtained from + `here `_. + + Alternatively, the Marvell SDK also provides GNU GCC toolchain, which is + optimized for cnxk CPU. + +3. **Rootfile system** + + Any *aarch64* supporting filesystem may be used. For example, + Ubuntu 15.10 (Wily) or 16.04 LTS (Xenial) userland which can be obtained + from ``_. + + Alternatively, the Marvell SDK provides the buildroot based root filesystem. + The SDK includes all the above prerequisites necessary to bring up the cnxk board. + +- Follow the DPDK :doc:`../linux_gsg/index` to setup the basic DPDK environment. + + +Debugging Options +----------------- + +.. _table_cnxk_common_debug_options: + +.. table:: cnxk common debug options + + +---+------------+-------------------------------------------------------+ + | # | Component | EAL log command | + +===+============+=======================================================+ + | 1 | Common | --log-level='pmd\.cnxk\.base,8' | + +---+------------+-------------------------------------------------------+ + | 2 | Mailbox | --log-level='pmd\.cnxk\.mbox,8' | + +---+------------+-------------------------------------------------------+ + +Debugfs support +~~~~~~~~~~~~~~~ + +The **RVU AF Linux kernel driver** provides support to dump RVU blocks +context or stats using debugfs. + +Enable ``debugfs`` by: + +1.
