[igt-dev] [PATCH i-g-t v4 2/6] lib: Update platform definitions with blitter information

Karolina Stolarek karolina.stolarek at intel.com
Tue Jan 17 09:51:12 UTC 2023


Update entries in intel_device_info to store information on
supported blitter commands and tiling formats. Add predicates
that check if block or fast copy are supported. Update block
copy tests to use the new checks.
