Here's v4 series to improve resctrl selftests with generalized test framework and rewritten CAT test.

The series contains following improvements:

• Excludes shareable bits from CAT test allocation to avoid interference
• Replaces file "sink" with a volatile variable
• Alters read pattern to defeat HW prefetcher optimizations
• Rewrites CAT test to make the CAT test reliable and truly measure if CAT is working or not
• Introduces generalized test framework making easier to add new tests
• Lots of other cleanups & refactoring

This series has been tested across a large number of systems from different generations.

Ilpo, thank you very much for this great cleanup and a creating a reliable CAT test. This work is focused on kernel health and greatly appreciated.

All patches in this series should have my reviewed-by tag. For confirmation, for this whole series: Reviewed-by: Reinette Chatre reinette.chatre@intel.com

Shuah, could you please consider this series for inclusion at your convenience?

Thank you very much.
