+QPL Compression
+===============
+The Intel Query Processing Library (Intel ``QPL``) is an open-source library to
+provide compression and decompression features and it is based on deflate
+compression algorithm (RFC 1951).
+
+The ``QPL`` compression relies on Intel In-Memory Analytics Accelerator(``IAA``)
+and Shared Virtual Memory(``SVM``) technology, they are new features supported
+from Intel 4th Gen Intel Xeon Scalable processors, codenamed Sapphire Rapids
+processor(``SPR``).
+
+For more ``QPL`` introduction, please refer to `QPL Introduction
+<https://intel.github.io/qpl/documentation/introduction_docs/introduction.html>`_

+QPL Build And Installation
+--------------------------
+
+.. code-block:: shell
+
+  $git clone --recursive https://github.com/intel/qpl.git qpl
+  $mkdir qpl/build
+  $cd qpl/build
+  $cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr -DQPL_LIBRARY_TYPE=SHARED ..
+  $sudo cmake --build . --target install
+
+For more details about ``QPL`` installation, please refer to `QPL Installation
+<https://intel.github.io/qpl/documentation/get_started_docs/installation.html>`_
+
+IAA Device Management
+---------------------
+
+The number of ``IAA`` devices will vary depending on the Xeon product model.
+On a ``SPR`` server, there can be a maximum of 8 ``IAA`` devices, with up to
+4 devices per socket.
+
+By default, all ``IAA`` devices are disabled and need to be configured and
+enabled by users manually.
+
+Check the number of devices through the following command
+
+.. code-block:: shell
+
+  #lspci -d 8086:0cfe
+  6a:02.0 System peripheral: Intel Corporation Device 0cfe
+  6f:02.0 System peripheral: Intel Corporation Device 0cfe
+  74:02.0 System peripheral: Intel Corporation Device 0cfe
+  79:02.0 System peripheral: Intel Corporation Device 0cfe
+  e7:02.0 System peripheral: Intel Corporation Device 0cfe
+  ec:02.0 System peripheral: Intel Corporation Device 0cfe
+  f1:02.0 System peripheral: Intel Corporation Device 0cfe
+  f6:02.0 System peripheral: Intel Corporation Device 0cfe
+
+IAA Device Configuration And Enabling
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The ``accel-config`` tool is used to enable ``IAA`` devices and configure
+``IAA`` hardware resources(work queues and engines). One ``IAA`` device
+has 8 work queues and 8 processing engines, multiple engines can be assigned
+to a work queue via ``group`` attribute.
+
+For ``accel-config`` installation, please refer to `accel-config installation
+<https://github.com/intel/idxd-config>`_
+
+One example of configuring and enabling an ``IAA`` device.
+
+.. code-block:: shell
+
+  #accel-config config-engine iax1/engine1.0 -g 0
+  #accel-config config-engine iax1/engine1.1 -g 0
+  #accel-config config-engine iax1/engine1.2 -g 0
+  #accel-config config-engine iax1/engine1.3 -g 0
+  #accel-config config-engine iax1/engine1.4 -g 0
+  #accel-config config-engine iax1/engine1.5 -g 0
+  #accel-config config-engine iax1/engine1.6 -g 0
+  #accel-config config-engine iax1/engine1.7 -g 0
+  #accel-config config-wq iax1/wq1.0 -g 0 -s 128 -p 10 -b 1 -t 128 -m shared -y user -n app1 -d user
+  #accel-config enable-device iax1
+  #accel-config enable-wq iax1/wq1.0
+
+.. note::
+   IAX is an early name for IAA
+
+- The ``IAA`` device index is 1, use ``ls -lh /sys/bus/dsa/devices/iax*``
+  command to query the ``IAA`` device index.
+
+- 8 engines and 1 work queue are configured in group 0, so all compression jobs
+  submitted to this work queue can be processed by all engines at the same time.
+
+- Set work queue attributes including the work mode, work queue size and so on.
+
+- Enable the ``IAA1`` device and work queue 1.0
+
+.. note::
+
+  Set work queue mode to shared mode, since ``QPL`` library only supports
+  shared mode
+
+For more detailed configuration, please refer to `IAA Configuration Samples
+<https://github.com/intel/idxd-config/tree/stable/Documentation/accfg>`_
+
+IAA Unit Test
+^^^^^^^^^^^^^
+
+- Enabling ``IAA`` devices for Xeon platform, please refer to `IAA User Guide
+  <https://www.intel.com/content/www/us/en/content-details/780887/intel-in-memory-analytics-accelerator-intel-iaa.html>`_
+
+- ``IAA`` device driver is Intel Data Accelerator Driver (idxd), it is
+  recommended that the minimum version of Linux kernel is 5.18.
+
+- Add ``"intel_iommu=on,sm_on"`` parameter to kernel command line
+  for ``SVM`` feature enabling.
+
+Here is an easy way to verify ``IAA`` device driver and ``SVM`` with `iaa_test
+<https://github.com/intel/idxd-config/tree/stable/test>`_
+
+.. code-block:: shell
+
+  #./test/iaa_test
+   [ info] alloc wq 0 shared size 128 addr 0x7f26cebe5000 batch sz 0xfffffffe xfer sz 0x80000000
+   [ info] test noop: tflags 0x1 num_desc 1
+   [ info] preparing descriptor for noop
+   [ info] Submitted all noop jobs
+   [ info] verifying task result for 0x16f7e20
+   [ info] test with op 0 passed
+
+
+IAA Resources Allocation For Migration
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+There is no ``IAA`` resource configuration parameters for migration and
+``accel-config`` tool configuration cannot directly specify the ``IAA``
+resources used for migration.
+
+The multifd migration with ``QPL`` compression method  will use all work
+queues that are enabled and shared mode.
+
+.. note::
+
+  Accessing IAA resources requires ``sudo`` command or ``root`` privileges
+  by default. Administrators can modify the IAA device node ownership
+  so that Qemu can use IAA with specified user permissions.
+
+  For example
+
+  #chown -R Qemu /dev/iax
+
+
+Shared Virtual Memory(SVM) Introduction
+=======================================
+
+An ability for an accelerator I/O device to operate in the same virtual
+memory space of applications on host processors. It also implies the
+ability to operate from pageable memory, avoiding functional requirements
+to pin memory for DMA operations.
+
+When using ``SVM`` technology, users do not need to reserve memory for the
+``IAA`` device and perform pin memory operation. The ``IAA`` device can
+directly access data using the virtual address of the process.
+
+For more ``SVM`` technology, please refer to
+`Shared Virtual Addressing (SVA) with ENQCMD
+<https://docs.kernel.org/next/x86/sva.html>`_
+
+
+How To Use QPL Compression In Migration
+=======================================
+
+1 - Installation of ``QPL`` library and ``accel-config`` library if using IAA
+
+2 - Configure and enable ``IAA`` devices and work queues via ``accel-config``
+
+3 - Build ``Qemu`` with ``--enable-qpl`` parameter
+
+  E.g. configure --target-list=x86_64-softmmu --enable-kvm ``--enable-qpl``
+
+4 - Enable ``QPL`` compression during migration
+
+  Set ``migrate_set_parameter multifd-compression qpl`` when migrating, the
+  ``QPL`` compression does not support configuring the compression level, it
+  only supports one compression level.
+
+The Difference Between QPL And ZLIB
+===================================
+
+Although both ``QPL`` and ``ZLIB`` are based on the deflate compression
+algorithm, and ``QPL`` can support the header and tail of ``ZLIB``, ``QPL``
+is still not fully compatible with the ``ZLIB`` compression in the migration.
+
+``QPL`` only supports 4K history buffer, and ``ZLIB`` is 32K by default. The
+``ZLIB`` compressed data that ``QPL`` may not decompress correctly and
+vice versa.
+
+``QPL`` does not support the ``Z_SYNC_FLUSH`` operation in ``ZLIB`` streaming
+compression, current ``ZLIB`` implementation uses ``Z_SYNC_FLUSH``, so each
+``multifd`` thread has a ``ZLIB`` streaming context, and all page compression
+and decompression are based on this stream. ``QPL`` cannot decompress such data
+and vice versa.
+
+The introduction for ``Z_SYNC_FLUSH``, please refer to `Zlib Manual
+<https://www.zlib.net/manual.html>`_
+
+The Best Practices
+==================
+When user enables the IAA device for ``QPL`` compression, it is recommended
+to add ``-mem-prealloc`` parameter to the destination boot parameters. This
+parameter can avoid the occurrence of I/O page fault and reduce the overhead
+of IAA compression and decompression.
+
+The example of booting with ``-mem-prealloc`` parameter
+
+.. code-block:: shell
+
+   $qemu-system-x86_64 --enable-kvm -cpu host --mem-prealloc ...
+
+
+An example about I/O page fault measurement of destination without
+``-mem-prealloc``, the ``svm_prq`` indicates the number of I/O page fault
+occurrences and processing time.
+
+.. code-block:: shell
+
+  #echo 1 > /sys/kernel/debug/iommu/intel/dmar_perf_latency
+  #echo 2 > /sys/kernel/debug/iommu/intel/dmar_perf_latency
+  #echo 3 > /sys/kernel/debug/iommu/intel/dmar_perf_latency
+  #echo 4 > /sys/kernel/debug/iommu/intel/dmar_perf_latency
