[Intel-gfx] [PATCH] drm/i915/selftests: Drop igt_cs_tlb
From: Jonathan Cavitt
The gt_tlb live selftest has the same code coverage as the
igt_cs_tlb subtest of gtt, except it is better at detecting
TLB bugs. Furthermore, while igt_cs_tlb is hitting some
unforeseen issues, these issues are either false positives
due to the test being poorly formatted, or are true
positives that can be more easily diagnosed with smaller
tests. As such, igt_cs_tlb is superceded by and obsoleted
by gt_tlb, meaning it can be removed.

True, the intent of the code is the same, but gt_tlb has had a much high success rate at hitting TLB bugs, so is my preferred test. > However, igt_cs_tlb is hitting > an issue in that we are updating PTE in gt0->vm but > executing on the media tile without updating gt1->vm. I'm no longer convinced this a good explanation of the issue, as unlike the i915_requests selftest this is using a GEM context and not the local kernel contexts. The GEM context->vm should work equally on the mtl render and media tiles, afaict. The failure is very early in running on media tile (after running on the render tile) so I think it should be easy enough to reproduce in a simpler test to narrow down the cause. > This issue is corrected in gt_tlb, and thus igt_cs_tlb > is obsolete and should be removed. gt_tlb supersedes igt_cs_tlb, that I can agree on, Acked-by: Chris Wilson -Chris
[Intel-gfx] [PATCH] drm/i915/selftests: Drop igt_cs_tlb
The gt_tlb live selftest has the same code coverage as the
igt_cs_tlb subtest of gtt. However, igt_cs_tlb is hitting
an issue in that we are updating PTE in gt0->vm but
executing on the media tile without updating gt1->vm.
This issue is corrected in gt_tlb, and thus igt_cs_tlb
is obsolete and should be removed.
