Cover letter [igt-dev] [PATCH v2 0/1] Skip 2x-cursor-vs-flip subtests for gen > 9
Skip the following for gen > 9
1.) tests/kms_cursor_legacy@2x-cursor-vs-flip-atomic 2.) tests/kms_cursor_legacy@2x-cursor-vs-flip-legacy 3.) tests/kms_cursor_legacy@2x-long-cursor-vs-flip-atomic 4.) tests/kms_cursor_legacy@2x-long-cursor-vs-flip-legacy
Due to DDB allocation changes, we have to add all the planes to the drm_atomic_state post gen 9. When the watermarks are computed by the kernel, the cursor plane is added to the drm_atomic_state which introduces a dependency on hw_done object when the kernel processes DRM_IOCTL_MODE_ATOMIC and DRM_IOCTL_MODE_CURSOR in parallel. There is no race-free way to handle this corner case. These subtests made sense for older generations but not anymore. Hence, skipping these sub-tests post gen 9.
