* [igt-dev] [PATCH] tests/amdgpu/amd_checksum_region: Add test for checksum_region
@ 2023-06-29 15:10 Alan Liu

  To: igt-dev; +Cc: Alan Liu, Lili.Gong

Introduce IGT of checksum_region. Checksum_region allows userspace to
set a region on display and get the CRC data accordingly via CRTC
properties: CHECKSUM_REGION and CEHCKSUM_CRC.
This IGT provides tests to validate if region can be set correctly and
also the corresponding CRC data is as expect.
