[PATCH i-g-t 1/3] lib/igt_fb: Allow specifiying object tiling when creating frame buffers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>

Currently object tiling is inferred from the frame buffer modifier
and only for legacy X scanout.

It is useful to support overriding this selection for certain tests
so add the capability.
