[igt-dev] [PATCH i-g-t v5 4/4] tests/kms_dirtyfb: Add new test for dirtyfb ioctl
Jouni Högander
jouni.hogander at intel.com
Mon Jun 19 12:56:33 UTC 2023
Add new test to validate dirtyfb ioctl is working properly with GPU
frontbuffer rendering.
Create big framebuffer and use only lower right corner for the
plane. Initiate GPU drawing for a rectangle over the whole
framebuffer and perform dirtyfb ioctl. Then wait for the drawing to
complete and collect crc and check that it matches with expected.
v5:
- Modifiations to support Xe as well
v4:
- Check connector type when PSR is tested
v3:
- Use spinner
- Drop allocating big frambuffers
v2:
- Change license comment
- Move disable_features and do not apply for FEATURE_DEFAULT
