[igt-dev] [PATCH i-g-t v3 15/17] tests/xe_exercise_blt: Check blitter library fast-copy for Xe

Tue Jul 11 11:20:07 UTC 2023


Port this test to work on xe. Instead of adding conditional code for
xe code which would decrease readability this is new test for xe.

v3: - Explicitely release offsets and unbind (Karolina)
    - Use has-fast-copy instead of copied has-block-copy check (Karolina)
