drm/drivers: add support for using the arch wc mapping API.

2018-09-09T18:04:36Z

commit 7cf321d118a825c1541b43ca45294126fd474efa upstream. This fixes a regression in all these drivers since the cache mode tracking was fixed for mixed mappings. It uses the new arch API to add the VRAM range to the PAT mapping tracking tables. Fixes: 87744ab3832 (mm: fix cache mode tracking in vm_insert_mixed()) Reviewed-by: Christian König .

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

2016-05-11T09:21:22Z

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

2015-11-30T19:41:33Z

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. Signed-off-by: Christian König Signed-off-by: Alex Deucher

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

2015-08-17T20:51:13Z

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.
