31 CXGBE Poll Mode Driver
32 ======================
34 The CXGBE PMD (**librte_pmd_cxgbe**) provides poll mode driver support
35 for **Chelsio T5** 10/40 Gbps family of adapters. CXGBE PMD has support
36 for the latest Linux and FreeBSD operating systems.
38 More information can be found at `Chelsio Communications Official Website
39 <http://www.chelsio.com>`_.
44 CXGBE PMD has support for:
46 - Multiple queues for TX and RX
47 - Receiver Side Steering (RSS)
52 - Port hardware statistics
57 The Chelsio T5 devices provide two/four ports but expose a single PCI bus
58 address, thus, librte_pmd_cxgbe registers itself as a
59 PCI driver that allocates one Ethernet device per detected port.
61 For this reason, one cannot whitelist/blacklist a single port without
62 whitelisting/blacklisting the other ports on the same device.
64 Supported Chelsio T5 NICs
65 -------------------------
68 - 10G NICs: T520-BT, T520-CR, T520-LL-CR, T520-SO-CR, T540-CR
69 - 40G NICs: T580-CR, T580-LP-CR, T580-SO-CR
70 - Other T5 NICs: T522-CR
75 - Requires firmware version **1.13.32.0** and higher. Visit
76 `Chelsio Download Center <http://service.chelsio.com>`_ to get latest firmware
77 bundled with the latest Chelsio Unified Wire package.
79 For Linux, installing and loading the latest cxgb4 kernel driver from the
80 Chelsio Unified Wire package should get you the latest firmware. More
81 information can be obtained from the User Guide that is bundled with the
82 Chelsio Unified Wire package.
84 For FreeBSD, the latest firmware obtained from the Chelsio Unified Wire
85 package must be manually flashed via cxgbetool available in FreeBSD source
88 Instructions on how to manually flash the firmware are given in section
89 :ref:`linux-installation` for Linux and section :ref:`freebsd-installation`
92 Pre-Installation Configuration

214 Sample Application Notes
215 ~~~~~~~~~~~~~~~~~~~~~~~~
217 This section demonstrates how to launch **testpmd** with Chelsio T5
218 devices managed by librte_pmd_cxgbe in Linux operating system.
220 #. Change to DPDK source directory where the target has been compiled in
221 section :ref:`driver-compilation`:
223 .. code-block:: console
225 cd <DPDK-source-directory>
227 #. Load the kernel module:
229 .. code-block:: console
233 #. Get the PCI bus addresses of the interfaces bound to cxgb4 driver:
235 .. code-block:: console
241 .. code-block:: console
243 cxgb4 0000:02:00.4 p1p1: renamed from eth0
244 cxgb4 0000:02:00.4 p1p2: renamed from eth1
248 Both the interfaces of a Chelsio T5 2-port adapter are bound to the
249 same PCI bus address.
251 #. Unload the kernel module:
253 .. code-block:: console
255 modprobe -ar cxgb4 csiostor
257 #. Request huge pages:
259 .. code-block:: console
261 echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages/nr_hugepages
263 #. Load igb_uio or vfio-pci driver:
265 .. code-block:: console
267 insmod ./x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
271 .. code-block:: console
275 #. Bind the Chelsio T5 adapters to igb_uio or vfio-pci loaded in the previous
278 .. code-block:: console
280 ./tools/dpdk_nic_bind.py --bind igb_uio 0000:02:00.4
284 Setup VFIO permissions for regular users and then bind to vfio-pci:
286 .. code-block:: console
288 sudo chmod a+x /dev/vfio
290 sudo chmod 0666 /dev/vfio/*
292 ./tools/dpdk_nic_bind.py --bind vfio-pci 0000:02:00.4
296 Currently, CXGBE PMD only supports the binding of PF4 for Chelsio T5 NICs.
298 #. Start testpmd with basic parameters:
300 .. code-block:: console
302 ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -w 0000:02:00.4 -- -i

337 testpmd> set flow_ctrl rx on tx on 0 0 0 0 mac_ctrl_frame_fwd off autoneg on 1

344 testpmd> set flow_ctrl rx off tx off 0 0 0 0 mac_ctrl_frame_fwd off autoneg off 1
349 .. _freebsd-installation:
354 Steps to manually install the latest firmware from the downloaded Chelsio
355 Unified Wire package for FreeBSD operating system are as follows:
357 #. Load the kernel module:
359 .. code-block:: console
363 #. Use dmesg to get the t5nex instance assigned to the Chelsio card:
365 .. code-block:: console
371 .. code-block:: console
373 t5nex0: <Chelsio T520-CR> irq 16 at device 0.4 on pci2
374 cxl0: <port 0> on t5nex0
375 cxl1: <port 1> on t5nex0
376 t5nex0: PCIe x8, 2 ports, 14 MSI-X interrupts, 31 eq, 13 iq
378 In the example above, a Chelsio T520-CR card is bound to a t5nex0 instance.
380 #. Install cxgbetool from FreeBSD source repository:
382 .. code-block:: console
384 cd <path_to_FreeBSD_source>/tools/tools/cxgbetool/
387 #. Use cxgbetool to load the firmware image onto the card:
389 .. code-block:: console
391 cxgbetool t5nex0 loadfw <path_to_uwire>/src/network/firmware/t5fw-*.bin
393 #. Unload and reload the kernel module:
395 .. code-block:: console
400 #. Verify with sysctl:
402 .. code-block:: console
404 sysctl -a | grep "t5nex" | grep "firmware"
408 .. code-block:: console
410 dev.t5nex.0.firmware_version: 1.13.32.0
412 Sample Application Notes
413 ~~~~~~~~~~~~~~~~~~~~~~~~
415 This section demonstrates how to launch **testpmd** with Chelsio T5
416 devices managed by librte_pmd_cxgbe in FreeBSD operating system.
418 #. Change to DPDK source directory where the target has been compiled in
419 section :ref:`driver-compilation`:
421 .. code-block:: console
423 cd <DPDK-source-directory>
425 #. Copy the contigmem kernel module to /boot/kernel directory:
427 .. code-block:: console
429 cp x86_64-native-bsdapp-clang/kmod/contigmem.ko /boot/kernel/
431 #. Add the following lines to /boot/loader.conf:
433 .. code-block:: console
435 # reserve 2 x 1G blocks of contiguous memory using contigmem driver
436 hw.contigmem.num_buffers=2
437 hw.contigmem.buffer_size=1073741824
438 # load contigmem module during boot process
441 The above lines load the contigmem kernel module during boot process and
442 allocate 2 x 1G blocks of contiguous memory to be used for DPDK later on.
443 This is to avoid issues with potential memory fragmentation during later
444 system up time, which may result in failure of allocating the contiguous
445 memory required for the contigmem kernel module.
447 #. Restart the system and ensure the contigmem module is loaded successfully:
449 .. code-block:: console
452 kldstat | grep "contigmem"
456 .. code-block:: console
458 2 1 0xffffffff817f1000 3118 contigmem.ko
460 #. Repeat step 1 to ensure that you are in the DPDK source directory.
462 #. Load the cxgbe kernel module:
464 .. code-block:: console
468 #. Get the PCI bus addresses of the interfaces bound to t5nex driver:
470 .. code-block:: console
472 pciconf -l | grep "t5nex"
476 .. code-block:: console
478 t5nex0@pci0:2:0:4: class=0x020000 card=0x00001425 chip=0x54011425 rev=0x00
480 In the above example, the t5nex0 is bound to 2:0:4 bus address.
484 Both the interfaces of a Chelsio T5 2-port adapter are bound to the
485 same PCI bus address.
487 #. Unload the kernel module:
489 .. code-block:: console
493 #. Set the PCI bus addresses to hw.nic_uio.bdfs kernel environment parameter:
495 .. code-block:: console
497 kenv hw.nic_uio.bdfs="2:0:4"
499 This automatically binds 2:0:4 to nic_uio kernel driver when it is loaded in
504 Currently, CXGBE PMD only supports the binding of PF4 for Chelsio T5 NICs.
506 #. Load nic_uio kernel driver:
508 .. code-block:: console
510 kldload ./x86_64-native-bsdapp-clang/kmod/nic_uio.ko
512 #. Start testpmd with basic parameters:
514 .. code-block:: console
