88 All the usual chains are supported and also some mixed chains:
90 .. table:: Supported hash-cipher chains for wireless digest-encrypted cases
92 +------------------+-----------+-------------+----------+----------+
93 | Cipher algorithm | NULL AUTH | SNOW3G UIA2 | ZUC EIA3 | AES CMAC |
94 +==================+===========+=============+==========+==========+
95 | NULL CIPHER | Y | 2&3 | 2&3 | Y |
96 +------------------+-----------+-------------+----------+----------+
97 | SNOW3G UEA2 | 2&3 | Y | 2&3 | 2&3 |

100 +------------------+-----------+-------------+----------+----------+
101 | AES CTR | Y | 2&3 | 2&3 | Y |
102 +------------------+-----------+-------------+----------+----------+
104 * The combinations marked as "Y" are supported on all QAT hardware versions.
105 * The combinations marked as "2&3" are supported on GEN2/GEN3 QAT hardware only.
111 * Only supports the session-oriented API implementation (session-less APIs are not supported).
112 * SNOW 3G (UEA2), KASUMI (F8) and ZUC (EEA3) supported only if cipher length and offset fields are byte-multiple.
113 * SNOW 3G (UIA2) and ZUC (EIA3) supported only if hash length and offset fields are byte-multiple.
114 * No BSD support as BSD QAT kernel driver not available.
115 * ZUC EEA3/EIA3 is not supported by dh895xcc devices
116 * Maximum additional authenticated data (AAD) for GCM is 240 bytes long and must be passed to the device in a buffer rounded up to the nearest block-size multiple (x16) and padded with zeros.
117 * Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
118 queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
119 from the RX queue must be done from one thread, but enqueues and dequeues may be done
120 in different threads.)
121 * A GCM limitation exists, but only in the case where there are multiple
122 generations of QAT devices on a single platform.
123 To optimise performance, the GCM crypto session should be initialised for the
124 device generation to which the ops will be enqueued. Specifically if a GCM
125 session is initialised on a GEN2 device, but then attached to an op enqueued
126 to a GEN3 device, it will work but cannot take advantage of hardware
127 optimisations in the GEN3 device. And if a GCM session is initialised on a
128 GEN3 device, then attached to an op sent to a GEN1/GEN2 device, it will not be
129 enqueued to the device and will be marked as failed. The simplest way to
130 mitigate this is to use the bdf whitelist to avoid mixing devices of different
131 generations in the same process if planning to use for GCM.
132 * The mixed algo feature on GEN2 is not supported by all kernel drivers. Check
133 the notes under the Available Kernel Drivers table below for specific details.
134 * Out-of-place is not supported for combined Crypto-CRC DOCSIS security
136 * ``RTE_CRYPTO_CIPHER_DES_DOCSISBPI`` is not supported for combined Crypto-CRC
137 DOCSIS security protocol.
138 * Multi-segment buffers are not supported for combined Crypto-CRC DOCSIS
141 Extra notes on KASUMI F9
142 ~~~~~~~~~~~~~~~~~~~~~~~~
144 When using KASUMI F9 authentication algorithm, the input buffer must be
145 constructed according to the
146 `3GPP KASUMI specification <http://cryptome.org/3gpp/35201-900.pdf>`_
147 (section 4.4, page 13). The input buffer has to have COUNT (4 bytes),
148 FRESH (4 bytes), MESSAGE and DIRECTION (1 bit) concatenated. After the DIRECTION
149 bit, a single '1' bit is appended, followed by between 0 and 7 '0' bits, so that
150 the total length of the buffer is multiple of 8 bits. Note that the actual
151 message can be any length, specified in bits.
153 Once this buffer is passed this way, when creating the crypto operation,
154 length of data to authenticate "op.sym.auth.data.length" must be the length
155 of all the items described above, including the padding at the end.
156 Also, offset of data to authenticate "op.sym.auth.data.offset"
157 must be such that points at the start of the COUNT bytes.
159 Asymmetric Crypto Service on QAT
160 --------------------------------
162 The QAT asymmetric crypto PMD (hereafter referred to as `QAT ASYM [PMD]`) provides
163 poll mode crypto driver support for the following hardware accelerator devices:
165 * ``Intel QuickAssist Technology DH895xCC``
166 * ``Intel QuickAssist Technology C62x``
167 * ``Intel QuickAssist Technology C3xxx``
168 * ``Intel QuickAssist Technology D15xx``
169 * ``Intel QuickAssist Technology C4xxx``
171 The QAT ASYM PMD has support for:
173 * ``RTE_CRYPTO_ASYM_XFORM_MODEX``
174 * ``RTE_CRYPTO_ASYM_XFORM_MODINV``
179 * Big integers longer than 4096 bits are not supported.
180 * Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
181 queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
182 from the RX queue must be done from one thread, but enqueues and dequeues may be done
183 in different threads.)
184 * RSA-2560, RSA-3584 are not supported
191 A QAT device can host multiple acceleration services:
193 * symmetric cryptography
195 * asymmetric cryptography
197 These services are provided to DPDK applications via PMDs which register to
198 implement the corresponding cryptodev and compressdev APIs. The PMDs use
199 common QAT driver code which manages the QAT PCI device. They also depend on a
200 QAT kernel driver being installed on the platform, see :ref:`qat_kernel` below.
203 Configuring and Building the DPDK QAT PMDs
204 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
207 Further information on configuring, building and installing DPDK is described
208 :doc:`here <../linux_gsg/build_dpdk>`.
211 Quick instructions for QAT cryptodev PMD are as follows:
213 .. code-block:: console
215 cd to the top-level DPDK directory
217 sed -i 's,\(CONFIG_RTE_LIBRTE_PMD_QAT_SYM\)=n,\1=y,' build/.config
219 sed -i 's,\(CONFIG_RTE_LIBRTE_PMD_QAT_ASYM\)=n,\1=y,' build/.config
222 Quick instructions for QAT compressdev PMD are as follows:
224 .. code-block:: console
226 cd to the top-level DPDK directory
231 .. _building_qat_config:
236 These are the build configuration options affecting QAT, and their default values:
238 .. code-block:: console
240 CONFIG_RTE_LIBRTE_PMD_QAT=y
241 CONFIG_RTE_LIBRTE_PMD_QAT_SYM=n
242 CONFIG_RTE_LIBRTE_PMD_QAT_ASYM=n
243 CONFIG_RTE_PMD_QAT_MAX_PCI_DEVICES=48
244 CONFIG_RTE_PMD_QAT_COMP_IM_BUFFER_SIZE=65536
246 CONFIG_RTE_LIBRTE_PMD_QAT must be enabled for any QAT PMD to be built.
248 Both QAT SYM PMD and QAT ASYM PMD have an external dependency on libcrypto, so are not
249 built by default. CONFIG_RTE_LIBRTE_PMD_QAT_SYM/ASYM should be enabled to build them.
251 The QAT compressdev PMD has no external dependencies, so needs no configuration
252 options and is built by default.
254 The number of VFs per PF varies - see table below. If multiple QAT packages are
255 installed on a platform then CONFIG_RTE_PMD_QAT_MAX_PCI_DEVICES should be
256 adjusted to the number of VFs which the QAT common code will need to handle.
260 There are separate config items (not QAT-specific) for max cryptodevs
261 CONFIG_RTE_CRYPTO_MAX_DEVS and max compressdevs CONFIG_RTE_COMPRESS_MAX_DEVS,
262 if necessary these should be adjusted to handle the total of QAT and other
263 devices which the process will use. In particular for crypto, where each
264 QAT VF may expose two crypto devices, sym and asym, it may happen that the
265 number of devices will be bigger than MAX_DEVS and the process will show an error
266 during PMD initialisation. To avoid this problem CONFIG_RTE_CRYPTO_MAX_DEVS may be
267 increased or -w, pci-whitelist domain:bus:devid:func option may be used.
270 QAT compression PMD needs intermediate buffers to support Deflate compression
271 with Dynamic Huffman encoding. CONFIG_RTE_PMD_QAT_COMP_IM_BUFFER_SIZE
272 specifies the size of a single buffer, the PMD will allocate a multiple of these,
273 plus some extra space for associated meta-data. For GEN2 devices, 20 buffers are
274 allocated while for GEN1 devices, 12 buffers are allocated, plus 1472 bytes overhead.
278 If the compressed output of a Deflate operation using Dynamic Huffman
279 Encoding is too big to fit in an intermediate buffer, then the
280 operation will be split into smaller operations and their results will
281 be merged afterwards.
282 This is not possible if any checksum calculation was requested - in such
283 case the code falls back to fixed compression.
284 To avoid this less performant case, applications should configure
285 the intermediate buffer size to be larger than the expected input data size
286 (compressed output size is usually unknown, so the only option is to make
287 larger than the input size).
290 Running QAT PMD with minimum threshold for burst size
291 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
293 If only a small number or packets can be enqueued. Each enqueue causes an expensive MMIO write.
294 These MMIO write occurrences can be optimised by setting any of the following parameters:
296 - qat_sym_enq_threshold
297 - qat_asym_enq_threshold
298 - qat_comp_enq_threshold
300 When any of these parameters is set rte_cryptodev_enqueue_burst function will
301 return 0 (thereby avoiding an MMIO) if the device is congested and number of packets
302 possible to enqueue is smaller.
303 To use this feature the user must set the parameter on process start as a device additional parameter::
305 -w 03:01.1,qat_sym_enq_threshold=32,qat_comp_enq_threshold=16
307 All parameters can be used with the same device regardless of order. Parameters are separated
308 by comma. When the same parameter is used more than once first occurrence of the parameter
310 Maximum threshold that can be set is 32.
313 Device and driver naming
314 ~~~~~~~~~~~~~~~~~~~~~~~~
316 * The qat cryptodev symmetric crypto driver name is "crypto_qat".
317 * The qat cryptodev asymmetric crypto driver name is "crypto_qat_asym".
319 The "rte_cryptodev_devices_get()" returns the devices exposed by either of these drivers.
321 * Each qat sym crypto device has a unique name, in format
322 "<pci bdf>_<service>", e.g. "0000:41:01.0_qat_sym".
323 * Each qat asym crypto device has a unique name, in format
324 "<pci bdf>_<service>", e.g. "0000:41:01.0_qat_asym".
325 This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
329 The cryptodev driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
331 The qat crypto device name is in the format of the worker parameter passed to the crypto scheduler.
333 * The qat compressdev driver name is "compress_qat".
334 The rte_compressdev_devices_get() returns the devices exposed by this driver.
336 * Each qat compression device has a unique name, in format
337 <pci bdf>_<service>, e.g. "0000:41:01.0_qat_comp".
338 This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
342 Dependency on the QAT kernel driver
343 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
345 To use QAT an SRIOV-enabled QAT kernel driver is required. The VF
346 devices created and initialised by this driver will be used by the QAT PMDs.
348 Instructions for installation are below, but first an explanation of the
349 relationships between the PF/VF devices and the PMDs visible to
352 Each QuickAssist PF device exposes a number of VF devices. Each VF device can
353 enable one symmetric cryptodev PMD and/or one asymmetric cryptodev PMD and/or
355 These QAT PMDs share the same underlying device and pci-mgmt code, but are
356 enumerated independently on their respective APIs and appear as independent
357 devices to applications.
361 Each VF can only be used by one DPDK process. It is not possible to share
362 the same VF across multiple processes, even if these processes are using
363 different acceleration services.
365 Conversely one DPDK process can use one or more QAT VFs and can expose both
366 cryptodev and compressdev instances on each of those VFs.
369 Available kernel drivers

406 The first 3 columns indicate the service:
408 * S = Symmetric crypto service (via cryptodev API)
409 * A = Asymmetric crypto service (via cryptodev API)
410 * C = Compression service (via compressdev API)
412 The ``Driver`` column indicates either the Linux kernel version in which
413 support for this device was introduced or a driver available on Intel's 01.org
414 website. There are both linux in-tree and 01.org kernel drivers available for some
415 devices. p = release pending.
417 If you are running on a kernel which includes a driver for your device, see
418 `Installation using kernel.org driver`_ below. Otherwise see
419 `Installation using 01.org QAT driver`_.
422 Installation using kernel.org driver
423 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
425 The examples below are based on the C62x device, if you have a different device
426 use the corresponding values in the above table.
428 In BIOS ensure that SRIOV is enabled and either:
431 * Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
433 Check that the QAT driver is loaded on your system, by executing::
437 You should see the kernel module for your device listed, e.g.::
440 intel_qat 82336 1 qat_c62x
442 Next, you need to expose the Virtual Functions (VFs) using the sysfs file system.
444 First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
449 You should see output similar to::
451 1a:00.0 Co-processor: Intel Corporation Device 37c8
452 3d:00.0 Co-processor: Intel Corporation Device 37c8
453 3f:00.0 Co-processor: Intel Corporation Device 37c8
455 Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
457 echo 16 > /sys/bus/pci/drivers/c6xx/0000:1a:00.0/sriov_numvfs
458 echo 16 > /sys/bus/pci/drivers/c6xx/0000:3d:00.0/sriov_numvfs
459 echo 16 > /sys/bus/pci/drivers/c6xx/0000:3f:00.0/sriov_numvfs
461 Check that the VFs are available for use. For example ``lspci -d:37c9`` should
462 list 48 VF devices available for a ``C62x`` device.
464 To complete the installation follow the instructions in
465 `Binding the available VFs to the DPDK UIO driver`_.
469 If the QAT kernel modules are not loaded and you see an error like ``Failed
470 to load MMP firmware qat_895xcc_mmp.bin`` in kernel logs, this may be as a
471 result of not using a distribution, but just updating the kernel directly.
473 Download firmware from the `kernel firmware repo
474 <http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/>`_.
476 Copy qat binaries to ``/lib/firmware``::
478 cp qat_895xcc.bin /lib/firmware
479 cp qat_895xcc_mmp.bin /lib/firmware
481 Change to your linux source root directory and start the qat kernel modules::
483 insmod ./drivers/crypto/qat/qat_common/intel_qat.ko
484 insmod ./drivers/crypto/qat/qat_dh895xcc/qat_dh895xcc.ko
489 If you see the following warning in ``/var/log/messages`` it can be ignored:
490 ``IOMMU should be enabled for SR-IOV to work correctly``.
493 Installation using 01.org QAT driver
494 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
496 Download the latest QuickAssist Technology Driver from `01.org
497 <https://01.org/packet-processing/intel%C2%AE-quickassist-technology-drivers-and-patches>`_.
498 Consult the *Getting Started Guide* at the same URL for further information.
500 The steps below assume you are:
502 * Building on a platform with one ``C62x`` device.
503 * Using package ``qat1.7.l.4.2.0-000xx.tar.gz``.
504 * On Fedora26 kernel ``4.11.11-300.fc26.x86_64``.
506 In the BIOS ensure that SRIOV is enabled and VT-d is disabled.
508 Uninstall any existing QAT driver, for example by running:
510 * ``./installer.sh uninstall`` in the directory where originally installed.
513 Build and install the SRIOV-enabled QAT driver::
518 # Copy the package to this location and unpack
519 tar zxof qat1.7.l.4.2.0-000xx.tar.gz
521 ./configure --enable-icp-sriov=host
524 You can use ``cat /sys/kernel/debug/qat<your device type and bdf>/version/fw`` to confirm the driver is correctly installed and is using firmware version 4.2.0.
525 You can use ``lspci -d:37c9`` to confirm the presence of the 16 VF devices available per ``C62x`` PF.
527 Confirm the driver is correctly installed and is using firmware version 4.2.0::
529 cat /sys/kernel/debug/qat<your device type and bdf>/version/fw
532 Confirm the presence of 48 VF devices - 16 per PF::
537 To complete the installation - follow instructions in `Binding the available VFs to the DPDK UIO driver`_.
541 If using a later kernel and the build fails with an error relating to
542 ``strict_stroul`` not being available apply the following patch:
546 /QAT/QAT1.6/quickassist/utilities/downloader/Target_CoreLibs/uclo/include/linux/uclo_platform.h
547 + #if LINUX_VERSION_CODE >= KERNEL_VERSION(3,18,5)
548 + #define STR_TO_64(str, base, num, endPtr) {endPtr=NULL; if (kstrtoul((str), (base), (num))) printk("Error strtoull convert %s\n", str); }
550 #if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,38)
551 #define STR_TO_64(str, base, num, endPtr) {endPtr=NULL; if (strict_strtoull((str), (base), (num))) printk("Error strtoull convert %s\n", str); }
553 #if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,25)
554 #define STR_TO_64(str, base, num, endPtr) {endPtr=NULL; strict_strtoll((str), (base), (num));}
556 #define STR_TO_64(str, base, num, endPtr) \
560 *(num) = -(simple_strtoull((str+1), &(endPtr), (base))); \
562 *(num) = simple_strtoull((str), &(endPtr), (base)); \
572 If the build fails due to missing header files you may need to do following::
574 sudo yum install zlib-devel
575 sudo yum install openssl-devel
576 sudo yum install libudev-devel
580 If the build or install fails due to mismatching kernel sources you may need to do the following::
582 sudo yum install kernel-headers-`uname -r`
583 sudo yum install kernel-src-`uname -r`
584 sudo yum install kernel-devel-`uname -r`
587 Binding the available VFs to the DPDK UIO driver
588 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
590 Unbind the VFs from the stock driver so they can be bound to the uio driver.
592 For an Intel(R) QuickAssist Technology DH895xCC device
593 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
595 The unbind command below assumes ``BDFs`` of ``03:01.00-03:04.07``, if your
596 VFs are different adjust the unbind command below::
598 for device in $(seq 1 4); do \
599 for fn in $(seq 0 7); do \
600 echo -n 0000:03:0${device}.${fn} > \
601 /sys/bus/pci/devices/0000\:03\:0${device}.${fn}/driver/unbind; \
605 For an Intel(R) QuickAssist Technology C62x device
606 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
608 The unbind command below assumes ``BDFs`` of ``1a:01.00-1a:02.07``,
609 ``3d:01.00-3d:02.07`` and ``3f:01.00-3f:02.07``, if your VFs are different
610 adjust the unbind command below::
612 for device in $(seq 1 2); do \
613 for fn in $(seq 0 7); do \
614 echo -n 0000:1a:0${device}.${fn} > \
615 /sys/bus/pci/devices/0000\:1a\:0${device}.${fn}/driver/unbind; \
617 echo -n 0000:3d:0${device}.${fn} > \
618 /sys/bus/pci/devices/0000\:3d\:0${device}.${fn}/driver/unbind; \
620 echo -n 0000:3f:0${device}.${fn} > \
621 /sys/bus/pci/devices/0000\:3f\:0${device}.${fn}/driver/unbind; \
625 For Intel(R) QuickAssist Technology C3xxx or 200xx or D15xx device
626 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
628 The unbind command below assumes ``BDFs`` of ``01:01.00-01:02.07``, if your
629 VFs are different adjust the unbind command below::
631 for device in $(seq 1 2); do \
632 for fn in $(seq 0 7); do \
633 echo -n 0000:01:0${device}.${fn} > \
634 /sys/bus/pci/devices/0000\:01\:0${device}.${fn}/driver/unbind; \
638 Bind to the DPDK uio driver
639 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
641 Install the DPDK igb_uio driver, bind the VF PCI Device id to it and use lspci
642 to confirm the VF devices are now in use by igb_uio kernel driver,
643 e.g. for the C62x device::
647 echo "8086 37c9" > /sys/bus/pci/drivers/igb_uio/new_id
651 Another way to bind the VFs to the DPDK UIO driver is by using the
652 ``dpdk-devbind.py`` script::
654 cd to the top-level DPDK directory
655 ./usertools/dpdk-devbind.py -b igb_uio 0000:03:01.1
660 QAT SYM crypto PMD can be tested by running the test application::
665 ./test -l1 -n1 -w <your qat bdf>
666 RTE>>cryptodev_qat_autotest
668 QAT ASYM crypto PMD can be tested by running the test application::
673 ./test -l1 -n1 -w <your qat bdf>
674 RTE>>cryptodev_qat_asym_autotest
676 QAT compression PMD can be tested by running the test application::
679 sed -i 's,\(CONFIG_RTE_COMPRESSDEV_TEST\)=n,\1=y,' build/.config
682 ./test -l1 -n1 -w <your qat bdf>
683 RTE>>compressdev_autotest
689 There are 2 sets of trace available via the dynamic logging feature:
691 * pmd.qat_dp exposes trace on the data-path.
692 * pmd.qat_general exposes all other trace.
694 pmd.qat exposes both sets of traces.
695 They can be enabled using the log-level option (where 8=maximum log level) on
696 the process cmdline, e.g. using any of the following::
698 --log-level="pmd.qat_general,8"
699 --log-level="pmd.qat_dp,8"
700 --log-level="pmd.qat,8"
704 The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
705 RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
706 for meson build and config/common_base for gnu make.
707 Also the dynamic global log level overrides both sets of trace, so e.g. no
708 QAT trace would display in this case::
710 --log-level="7" --log-level="pmd.qat_general,8"
