+
+
+Extra notes on KASUMI F9
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+When using KASUMI F9 authentication algorithm, the input buffer must be
+constructed according to the
+`3GPP KASUMI specification <http://cryptome.org/3gpp/35201-900.pdf>`_
+(section 4.4, page 13). The input buffer has to have COUNT (4 bytes),
+FRESH (4 bytes), MESSAGE and DIRECTION (1 bit) concatenated. After the DIRECTION
+bit, a single '1' bit is appended, followed by between 0 and 7 '0' bits, so that
+the total length of the buffer is multiple of 8 bits. Note that the actual
+message can be any length, specified in bits.
+
+Once this buffer is passed this way, when creating the crypto operation,
+length of data to authenticate "op.sym.auth.data.length" must be the length
+of all the items described above, including the padding at the end.
+Also, offset of data to authenticate "op.sym.auth.data.offset"
+must be such that points at the start of the COUNT bytes.
+
+
+
+.. _building_qat:
+
+Building PMDs on QAT
+--------------------
+
+A QAT device can host multiple acceleration services:
+
+* symmetric cryptography
+* data compression
+
+These services are provided to DPDK applications via PMDs which register to
+implement the corresponding cryptodev and compressdev APIs. The PMDs use
+common QAT driver code which manages the QAT PCI device. They also depend on a
+QAT kernel driver being installed on the platform, see :ref:`qat_kernel` below.
+
+
+Configuring and Building the DPDK QAT PMDs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+Further information on configuring, building and installing DPDK is described
+`here <http://dpdk.org/doc/guides/linux_gsg/build_dpdk.html>`_.
+
+
+Quick instructions for QAT cryptodev PMD are as follows:
+
+.. code-block:: console
+
+ cd to the top-level DPDK directory
+ make defconfig
+ sed -i 's,\(CONFIG_RTE_LIBRTE_PMD_QAT_SYM\)=n,\1=y,' build/.config
+ make
+
+Quick instructions for QAT compressdev PMD are as follows:
+
+.. code-block:: console
+
+ cd to the top-level DPDK directory
+ make defconfig
+ make
+
+
+Build Configuration
+~~~~~~~~~~~~~~~~~~~
+
+These are the build configuration options affecting QAT, and their default values:
+
+.. code-block:: console
+
+ CONFIG_RTE_LIBRTE_PMD_QAT=y
+ CONFIG_RTE_LIBRTE_PMD_QAT_SYM=n
+ CONFIG_RTE_PMD_QAT_MAX_PCI_DEVICES=48
+ CONFIG_RTE_PMD_QAT_COMP_SGL_MAX_SEGMENTS=16
+ CONFIG_RTE_PMD_QAT_COMP_IM_BUFFER_SIZE=65536
+
+CONFIG_RTE_LIBRTE_PMD_QAT must be enabled for any QAT PMD to be built.
+
+The QAT cryptodev PMD has an external dependency on libcrypto, so is not
+built by default. CONFIG_RTE_LIBRTE_PMD_QAT_SYM should be enabled to build it.
+
+The QAT compressdev PMD has no external dependencies, so needs no configuration
+options and is built by default.
+
+The number of VFs per PF varies - see table below. If multiple QAT packages are
+installed on a platform then CONFIG_RTE_PMD_QAT_MAX_PCI_DEVICES should be
+adjusted to the number of VFs which the QAT common code will need to handle.
+Note, there are separate config items for max cryptodevs CONFIG_RTE_CRYPTO_MAX_DEVS
+and max compressdevs CONFIG_RTE_COMPRESS_MAX_DEVS, if necessary these should be
+adjusted to handle the total of QAT and other devices which the process will use.
+
+QAT allocates internal structures to handle SGLs. For the compression service
+CONFIG_RTE_PMD_QAT_COMP_SGL_MAX_SEGMENTS can be changed if more segments are needed.
+An extra (max_inflight_ops x 16) bytes per queue_pair will be used for every increment.
+
+QAT compression PMD needs intermediate buffers to support Deflate compression
+with Dynamic Huffman encoding. CONFIG_RTE_PMD_QAT_COMP_IM_BUFFER_SIZE
+specifies the size of a single buffer, the PMD will allocate a multiple of these,
+plus some extra space for associated meta-data. For GEN2 devices, 20 buffers plus
+1472 bytes are allocated.
+
+.. Note::
+
+ If the compressed output of a Deflate operation using Dynamic Huffman
+ Encoding is too big to fit in an intermediate buffer, then the
+ operation will return RTE_COMP_OP_STATUS_ERROR and an error will be
+ displayed. Options for the application in this case
+ are to split the input data into smaller chunks and resubmit
+ in multiple operations or to configure QAT with
+ larger intermediate buffers.
+
+
+Device and driver naming
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+* The qat cryptodev driver name is "crypto_qat".
+ The "rte_cryptodev_devices_get()" returns the devices exposed by this driver.
+
+* Each qat crypto device has a unique name, in format
+ "<pci bdf>_<service>", e.g. "0000:41:01.0_qat_sym".
+ This name can be passed to "rte_cryptodev_get_dev_id()" to get the device_id.
+
+.. Note::
+
+ The qat crypto driver name is passed to the dpdk-test-crypto-perf tool in the "-devtype" parameter.
+
+ The qat crypto device name is in the format of the slave parameter passed to the crypto scheduler.
+
+* The qat compressdev driver name is "compress_qat".
+ The rte_compressdev_devices_get() returns the devices exposed by this driver.
+
+* Each qat compression device has a unique name, in format
+ <pci bdf>_<service>, e.g. "0000:41:01.0_qat_comp".
+ This name can be passed to rte_compressdev_get_dev_id() to get the device_id.
+
+.. _qat_kernel:
+
+Dependency on the QAT kernel driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To use QAT an SRIOV-enabled QAT kernel driver is required. The VF
+devices created and initialised by this driver will be used by the QAT PMDs.
+
+Instructions for installation are below, but first an explanation of the
+relationships between the PF/VF devices and the PMDs visible to
+DPDK applications.
+Each QuickAssist PF device exposes a number of VF devices. Each VF device can
+enable one cryptodev PMD and/or one compressdev PMD.
+These QAT PMDs share the same underlying device and pci-mgmt code, but are
+enumerated independently on their respective APIs and appear as independent
+devices to applications.
-Installation
-------------
+.. Note::
-To use the DPDK QAT PMD an SRIOV-enabled QAT kernel driver is required. The
-VF devices exposed by this driver will be used by QAT PMD.
+ Each VF can only be used by one DPDK process. It is not possible to share
+ the same VF across multiple processes, even if these processes are using
+ different acceleration services.
-If you are running on kernel 4.4 or greater, see instructions for
-`Installation using kernel.org driver`_ below. If you are on a kernel earlier
-than 4.4, see `Installation using 01.org QAT driver`_.
+ Conversely one DPDK process can use one or more QAT VFs and can expose both
+ cryptodev and compressdev instances on each of those VFs.
+
+
+Available kernel drivers
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Kernel drivers for each device are listed in the following table. Scroll right
+to check that the driver and device supports the service you require.

+
+
+The ``Driver`` column indicates either the Linux kernel version in which
+support for this device was introduced or a driver available on Intel's 01.org
+website. There are both linux and 01.org kernel drivers available for some
+devices. p = release pending.
+
+If you are running on a kernel which includes a driver for your device, see
+`Installation using kernel.org driver`_ below. Otherwise see
+`Installation using 01.org QAT driver`_.
+
+
+Installation using kernel.org driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The examples below are based on the C62x device, if you have a different device
+use the corresponding values in the above table.
+
+In BIOS ensure that SRIOV is enabled and either:
+
+* Disable VT-d or
+* Enable VT-d and set ``"intel_iommu=on iommu=pt"`` in the grub file.
+
+Check that the QAT driver is loaded on your system, by executing::
+
+ lsmod | grep qa
+
+You should see the kernel module for your device listed, e.g.::
+
+ qat_c62x 5626 0
+ intel_qat 82336 1 qat_c62x
+
+Next, you need to expose the Virtual Functions (VFs) using the sysfs file system.
+
+First find the BDFs (Bus-Device-Function) of the physical functions (PFs) of
+your device, e.g.::
+
+ lspci -d:37c8
+
+You should see output similar to::
+
+ 1a:00.0 Co-processor: Intel Corporation Device 37c8
+ 3d:00.0 Co-processor: Intel Corporation Device 37c8
+ 3f:00.0 Co-processor: Intel Corporation Device 37c8
+
+Enable the VFs for each PF by echoing the number of VFs per PF to the pci driver::
+
+ echo 16 > /sys/bus/pci/drivers/c6xx/0000:1a:00.0/sriov_numvfs
+ echo 16 > /sys/bus/pci/drivers/c6xx/0000:3d:00.0/sriov_numvfs
+ echo 16 > /sys/bus/pci/drivers/c6xx/0000:3f:00.0/sriov_numvfs
+
+Check that the VFs are available for use. For example ``lspci -d:37c9`` should
+list 48 VF devices available for a ``C62x`` device.
+
+To complete the installation follow the instructions in
+`Binding the available VFs to the DPDK UIO driver`_.
+
+.. Note::
+
+ If the QAT kernel modules are not loaded and you see an error like ``Failed
+ to load MMP firmware qat_895xcc_mmp.bin`` in kernel logs, this may be as a
+ result of not using a distribution, but just updating the kernel directly.
+
+ Download firmware from the `kernel firmware repo
+ <http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/>`_.
+
+ Copy qat binaries to ``/lib/firmware``::
+
+ cp qat_895xcc.bin /lib/firmware
+ cp qat_895xcc_mmp.bin /lib/firmware
+
+ Change to your linux source root directory and start the qat kernel modules::
+
+ insmod ./drivers/crypto/qat/qat_common/intel_qat.ko
+ insmod ./drivers/crypto/qat/qat_dh895xcc/qat_dh895xcc.ko
+
+
+.. Note::
+
+ If you see the following warning in ``/var/log/messages`` it can be ignored:
+ ``IOMMU should be enabled for SR-IOV to work correctly``.
Installation using 01.org QAT driver
-------------------------------------
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Download the latest QuickAssist Technology Driver from `01.org
-<https://01.org/packet-processing/intel%C2%AE-quickassist-technology-drivers-and-patches>`_
+<https://01.org/packet-processing/intel%C2%AE-quickassist-technology-drivers-and-patches>`_.
Consult the *Getting Started Guide* at the same URL for further information.
The steps below assume you are:
-* Building on a platform with one ``DH895xCC`` device.
-* Using package ``qatmux.l.2.3.0-34.tgz``.
-* On Fedora21 kernel ``3.17.4-301.fc21.x86_64``.
+* Building on a platform with one ``C62x`` device.
+* Using package ``qat1.7.l.4.2.0-000xx.tar.gz``.
+* On Fedora26 kernel ``4.11.11-300.fc26.x86_64``.
In the BIOS ensure that SRIOV is enabled and VT-d is disabled.
* ``./installer.sh uninstall`` in the directory where originally installed.
-* or ``rmmod qat_dh895xcc; rmmod intel_qat``.
Build and install the SRIOV-enabled QAT driver::
mkdir /QAT
cd /QAT
- # copy qatmux.l.2.3.0-34.tgz to this location
- tar zxof qatmux.l.2.3.0-34.tgz
- export ICP_WITHOUT_IOMMU=1
- ./installer.sh install QAT1.6 host
+ # Copy the package to this location and unpack
+ tar zxof qat1.7.l.4.2.0-000xx.tar.gz
+
+ ./configure --enable-icp-sriov=host
+ make install
+
+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.
+You can use ``lspci -d:37c9`` to confirm the presence of the 16 VF devices available per ``C62x`` PF.
+
+Confirm the driver is correctly installed and is using firmware version 4.2.0::
+
+ cat /sys/kernel/debug/qat<your device type and bdf>/version/fw
+
+
+Confirm the presence of 48 VF devices - 16 per PF::
+
+ lspci -d:37c9
-You can use ``cat /proc/icp_dh895xcc_dev0/version`` to confirm the driver is correctly installed.
-You can use ``lspci -d:443`` to confirm the bdf of the 32 VF devices are available per ``DH895xCC`` device.
To complete the installation - follow instructions in `Binding the available VFs to the DPDK UIO driver`_.

+Bind to the DPDK uio driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
-If you get an error, it's likely you're using a QAT kernel driver earlier than kernel 4.4.
+Install the DPDK igb_uio driver, bind the VF PCI Device id to it and use lspci
+to confirm the VF devices are now in use by igb_uio kernel driver,
+e.g. for the C62x device::
-To verify that the VFs are available for use - use ``lspci -d:443`` to confirm
-the bdf of the 32 VF devices are available per ``DH895xCC`` device.
+ cd to the top-level DPDK directory
+ modprobe uio
+ insmod ./build/kmod/igb_uio.ko
+ echo "8086 37c9" > /sys/bus/pci/drivers/igb_uio/new_id
+ lspci -vvd:37c9
-To complete the installation - follow instructions in `Binding the available VFs to the DPDK UIO driver`_.
-**Note**: If the QAT kernel modules are not loaded and you see an error like
- ``Failed to load MMP firmware qat_895xcc_mmp.bin`` this may be as a
- result of not using a distribution, but just updating the kernel directly.
+Another way to bind the VFs to the DPDK UIO driver is by using the
+``dpdk-devbind.py`` script::
-Download firmware from the kernel firmware repo at:
-http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/
+ cd to the top-level DPDK directory
+ ./usertools/dpdk-devbind.py -b igb_uio 0000:03:01.1
-Copy qat binaries to /lib/firmware:
-* ``cp qat_895xcc.bin /lib/firmware``
-* ``cp qat_895xcc_mmp.bin /lib/firmware``
+Testing
+~~~~~~~
-cd to your linux source root directory and start the qat kernel modules:
-* ``insmod ./drivers/crypto/qat/qat_common/intel_qat.ko``
-* ``insmod ./drivers/crypto/qat/qat_dh895xcc/qat_dh895xcc.ko``
+QAT crypto PMD can be tested by running the test application::
-**Note**:The following warning in /var/log/messages can be ignored:
- ``IOMMU should be enabled for SR-IOV to work correctly``
+ make defconfig
+ make test-build -j
+ cd ./build/app
+ ./test -l1 -n1 -w <your qat bdf>
+ RTE>>cryptodev_qat_autotest
+QAT compression PMD can be tested by running the test application::
+ make defconfig
+ sed -i 's,\(CONFIG_RTE_COMPRESSDEV_TEST\)=n,\1=y,' build/.config
+ make test-build -j
+ cd ./build/app
+ ./test -l1 -n1 -w <your qat bdf>
+ RTE>>compressdev_autotest
-Binding the available VFs to the DPDK UIO driver
-------------------------------------------------
-The unbind command below assumes ``bdfs`` of ``03:01.00-03:04.07``, if yours are different adjust the unbind command below::
+Debugging
+~~~~~~~~~
+
+There are 2 sets of trace available via the dynamic logging feature:
+
+* pmd.qat_dp exposes trace on the data-path.
+* pmd.qat_general exposes all other trace.
+
+pmd.qat exposes both sets of traces.
+They can be enabled using the log-level option (where 8=maximum log level) on
+the process cmdline, e.g. using any of the following::
- cd $RTE_SDK
- modprobe uio
- insmod ./build/kmod/igb_uio.ko
+ --log-level="pmd.qat_general,8"
+ --log-level="pmd.qat_dp,8"
+ --log-level="pmd.qat,8"
- for device in $(seq 1 4); do \
- for fn in $(seq 0 7); do \
- echo -n 0000:03:0${device}.${fn} > \
- /sys/bus/pci/devices/0000\:03\:0${device}.${fn}/driver/unbind; \
- done; \
- done
+.. Note::
- echo "8086 0443" > /sys/bus/pci/drivers/igb_uio/new_id
+ The global RTE_LOG_DP_LEVEL overrides data-path trace so must be set to
+ RTE_LOG_DEBUG to see all the trace. This variable is in config/rte_config.h
+ for meson build and config/common_base for gnu make.
+ Also the dynamic global log level overrides both sets of trace, so e.g. no
+ QAT trace would display in this case::
-You can use ``lspci -vvd:443`` to confirm that all devices are now in use by igb_uio kernel driver.
+ --log-level="7" --log-level="pmd.qat_general,8"
