drm/amdgpu: always register an MMU notifier for userptr

2022-12-08T10:15:40+00:00

commit b39df63b16b64a3af42695acb9bc567aad144776 upstream.

Since switching to HMM we always need that because we no longer grab
references to the pages.

drm/amdgpu: fix prime teardown order

2018-03-22T08:18:00+00:00

commit 342038d92403b3efa1138a8599666b9f026279d6 upstream.

We unmapped imported DMA-bufs when the GEM handle was dropped, not when the
hardware was done with the buffere.

drm: Remove unused drm_device from drm_gem_object_lookup()

2016-05-17T06:47:30+00:00

drm_gem_object_lookup() has never required the drm_device for its file
local translation of the user handle to the GEM object. Let's remove the
unused parameter and save some space.

All these are compile time constand and the

drm: Protect dev->filelist with its own mutex

2016-04-27T08:16:17+00:00

amdgpu gained dev->struct_mutex usage, and that's because it's walking
the dev->filelist list. Protect that list with it's own lock to take
one more step towards getting rid of struct_mutex usage in drivers
once and for all.

While doing the conversion I noticed that 2 debugfs files in i915
completely lacked appropriate locking. Fix that up too.

v2: don't forget to switch to drm_gem_object_unreference_unlocked.
