Subject: [igt-dev] [PATCH v2 0/1] Skip 2x-cursor-vs-flip subtests for gen > 9
Date: Tue, 12 Mar 2019 09:12:43 -0700 [thread overview]
Message-ID: <cover.1552406927.git.neel.desai@intel.com> (raw)
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.
