      drm/i915/tgl: Disable rc6 for debugging · ab37c4d7
      Chris Wilson authored
      Empirical evidence from CI tells us that our rc6 setup for Tigerlake is
      off. Disable rc6 on tgl temporary so that we gain CI coverage as we
      prepare a fix. It also appears that the BIOS on our tgl leaves rc6
      enabled, so we have to explicitly disable it on init.

      drm/i915/selftests: Tighten the timeout testing for partial mmaps · 07e98eb0
      Chris Wilson authored
      Currently, if there is time remaining before the start of the loop, we
      do one full iteration over many possible different chunks within the
      object. A full loop may take 50+s (depending on speed of indirect GTT
      mmapings) and we try separately with LINEAR, X and Y -- at which point
      igt times out. If we check more frequently, we will interrupt the loop
      upon our timeout -- it is hard to argue for as this significantly reduces
      the test coverage as we dramatically reduce the runtime. In practical
      terms, the coverage we should prioritise is in using different fence
      setups, forcing verification of the tile row computations over the
      current preference of checking extracting chunks. Though the exhaustive
      search is great given an infinite timeout, to improve our current
      coverage, we also add a randomised smoketest of partial mmaps. So let's
      do both, add a randomised smoketest of partial tiling chunks and the
      exhaustive (though time limited) search for failures.
      
      Even in adding another subtest, we should shave 100s off BAT! (With,
      hopefully, no loss in coverage, at least over multiple runs.)

      drm/i915/selftests: Take runtime wakeref for igt_ggtt_lowlevel · 7c465310
      Chris Wilson authored
      Being a "low-level" test, we opt to bypass the normal bind/unbind hooks
      for the lower level insert_entries/clear_range. For ggtt, the
      bind/unbind hooks provide the runtime wakeref and so we must also handle
      this in exercising the low level hooks.
