[Intel-gfx] [PATCH i-g-t] i915: Remove gem_mocs_settings
Chris Wilson
chris at chris-wilson.co.uk
Fri Nov 15 10:32:16 UTC 2019
This igt relies on using privileged batches to read and modify protected
registers. This is no longer supported and so the test is entirely
defunct, and for as much as we can has been subsumed into a kernel
selftest.
