[igt-dev] [PATCH i-g-t 11/12] tests/xe_ccs: Check if flatccs is working with block-copy for Xe
Zbigniew Kempczyński

Tue Jul 4 09:01:03 UTC 2023
This is ported to xe copy of i915 gem_ccs test. Ported means all driver
dependent calls - like working on regions, binding and execution were
replaced by xe counterparts. I wondered to add conditionals for xe
in gem_ccs but this would decrease test readability so I dropped
this idea.
