[Bug 2020769] Re: [NEW SRU] backport accel-config for HWE support

[Kleber Sacilotto de Souza]

** Description changed:

  [ Impact ]
  
   * accel-config is a utility library for controlling and configuring DSA
  (Intel® Data Streaming Accelerator Architecture) and IAA (Intel®
  Analytics Accelerator Architecture) sub-systems in the Linux kernel
  
   * This is required/only userspace tooling for this hardware
  
   * Backport this package as part of HWE SRU exception
  
  [ Test Plan ]
  
-  * I don't have access to relevant hardware, thus we will rely on Intel
- partner (cking) to test and verify proposed packages
+  * We don't have access to relevant hardware, thus we will rely on Intel
+ partner (cking) to test and verify proposed packages.
  
+ * Hardware requirements: DSA/IAA enabled platform is required. This
+ means a 4th Generation Intel® Xeon® Scalable Processor is necessary.
+ 
+ * Kernel requirements:
+   - The kernel should have the IDXD module enabled (CONFIG_INTEL_IDXD_BUS=m, CONFIG_INTEL_IDXD=m, CONFIG_INTEL_IDXD_SVM=y).
+   - The recommended kernel version that contains support for these features is 5.18+.
+   - The kernel configs are enabled for the Lunar and Kinetic generic kernels.
+   - Therefore in Lunar and Kinetic the tests can be run with the generic kernels. In Jammy the tests need to be performed with the hwe-5.19 and hwe-6.2 kernels.
+ 
+ * Test procedure:
  1. install accel-config
- 2. with the accel-config sources, run the test_all.sh test script
+ 2. with the accel-config sources, run the test_all.sh test script (documentation at https://github.com/intel/idxd-config/tree/accel-config-v4.0/test)
  3. the script will report failures if they occur
- 
  
  [ Where problems could occur ]
  
   * For jammy this is a new package
   * For lunar upgrade, this should be trivial as the hardware in question is unlikely to be deployed with interim release
+  * As this package provides support for configuring features only provided by a processor family that has been recently launched, this package shouldn't cause any regression for older processors or kernel versions. 
  
  [ Other Info ]
  
   * Requested by Intel partner team.
