[igt-dev] [PATCH v3] kms_rotation_crc:Add HW rotation test case for amdgpu

Sung Joon Kim sungkim at amd.com
Thu Jan 21 23:03:04 UTC 2021


Added Hw rotation case specifically for amdgpu. Currently, kms_rotation_crc tests intel gpus. Added conditions to bypass all the requirements needed for intel when testing amdgpu.

v3: code cleanup. Freed unused fb. Merged all files into one patch due to dependency. Added tiling methods for amdgpu. Updated drm header for amdgpu tiling modifiers.
