Subject: [PATCH v4 0/5] selftests/resctrl: Add non-contiguous CBMs in Intel CAT selftest
Non-contiguous CBM support for Intel CAT has been merged into the kernel
with Commit 0e3cd31f6e90 ("x86/resctrl: Enable non-contiguous CBMs in
Intel CAT") but there is no selftest that would validate if this feature
works correctly.
The selftest needs to verify if writing non-contiguous CBMs to the
schemata file behaves as expected in comparison to the information about
non-contiguous CBMs support.
The patch series is based on a rework of resctrl selftests that's
currently in review [1]. The patch also implements a similar
functionality presented in the bash script included in the cover letter
of the original non-contiguous CBMs in Intel CAT series [3].
Changelog v4:
- Changes to error failure return values in non-contiguous test.
- Some minor text refactoring without functional changes.
Changelog v3:
- Rebase onto v4 of Ilpo's series [1].
- Split old patch 3/4 into two parts. One doing refactoring and one
adding a new function.
- Some changes to all the patches after Reinette's review.
Changelog v2:
- Rebase onto v4 of Ilpo's series [2].
- Add two patches that prepare helpers for the new test.
- Move Ilpo's patch that adds test grouping to this series.
- Apply Ilpo's suggestion to the patch that adds a new test.
