drm/amdgpu: set metadata pointer to NULL after freeing.

2016-05-11T09:21:38+00:00

commit 0092d3edcb23fcdb8cbe4159ba94a534290ff982 upstream.

Without this there was a double free of the metadata,
which ended up freeing the fd table for me here, and taking
out the machine more often than not.

I reproduced with X.org + modesetting DDX + latest llvm/mesa,
also required using dri3.

drm/amdgpu: fix VM page table reference counting

2015-11-30T19:41:33+00:00

We use the reservation object of the page directory for the page tables as
well, because of this the page directory should be freed last. Ensure that
by keeping a reference from the page tables to the directory.

drm/amdgpu: Don't take dev->struct_mutex in bo_force_delete

2015-08-17T20:51:13+00:00

It really doesn't protect anything which doesn't have other locks
already. Also this is run from driver unload code so not much need for
locks anyway.

Same changes as for radeon really.

drm/amdgpu: remove VI hw bug workaround v3

2015-08-17T20:51:11+00:00

The workaround simply doesn't work because VM mappings
are controlled by userspace not the kernel.

Additional to that this is just a performance problem
which happens if you have holes in your VM mapping.

v2: adjust virtual addr alignment as well.
v3: fix trivial warning
