Commit Message

Thomas Zimmermann Aug. 13, 2020, 8:36 a.m. UTC
GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in amdgpu. The only exception is gem_prime_mmap,
which is non-trivial to convert.

Wrong file, this belongs into amdgpu_gem.c

And this should probably go into amdgpu_gem_object_create().

Apart from that looks like a good idea to me.

I'm trying to understand what amdgpu does.  What about all the places
where amdgpu calls amdgpu_bo_create() internally? Wouldn't these miss
the free callback for the GEM object?

Best regards
