[igt-dev] [PATCH i-g-t 4/4] test/amdgpu: Add test for Sub-viewport

Thu Nov 2 20:00:00 UTC 2023
Sub-viewport is a power saving feature found on DCN32/DCN321 and newer dGPUs.
Add a test that commit a high resolution test pattern on multiple displays
and checks whether Sub-viewport feature is engaged.
