Hi Christian + Ben,
Just been reviewing around driver TTM code, and found an inconsistency,
amdgpu + radeon both call the above before binding the ttm and going
gpu vram->ram copies, but I don't see nouveau doing it Not sure if it
could cause any issues, but it does look inconsistent.
What amdgpu and radeon do here sounds superfluous to me. The tt
structure should have been allocated with the right caching attributes
in the first place.
BTW: Changing the caching attributes of pages on the fly is utterly
nonsense to begin with. This only works 100% correctly on x86, and there
only by coincident :)
Christian.
Dave.
