[Intel-gfx] [PATCH igt 1/3] kms_frontbuffer_tracking: prefer the BLT drawing method

[Paulo Zanoni]

A recent Kernel fix changed the way GTT and WC mmaps behave during
frontbuffer drawing. This, added with the fact that GTT mmaps are
special cases for PSR, suggests that maybe we should move to BLT
drawing in places where we can, in order to simplify things a little
bit.

v2: New commit message.
