2015-11-30drm/amdgpu: fix VM page table reference countingChristian König1-0/+1
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 <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2015-08-17drm/amdgpu: Don't take dev->struct_mutex in bo_force_deleteDaniel Vetter1-3/+1
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.

2015-08-17drm/amdgpu: remove VI hw bug workaround v3Christian König1-12/+0
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 Signed-off-by: Christian König <[email protected]> Reviewed-by: Monk Liu <[email protected]> (v1) Reviewed-by: Jammy Zhou <[email protected]> (v2)

2015-06-03drm/amdgpu: drop ttm two ended allocationAlex Deucher1-6/+0
amdgpu_bo_create() calls amdgpu_ttm_placement_from_domain() before ttm_bo_init() is called. amdgpu_ttm_placement_from_domain() uses the ttm bo size to determine when to select top down allocation but since the ttm bo is not initialized yet the check is always false. It only took affect when buffers were validated later. It also seemed to regress suspend and resume on some systems possibly due to it not taking affect in amdgpu_bo_create(). amdgpu_bo_create() and amdgpu_ttm_placement_from_domain() need to be reworked substantially for this to be optimally effective. Re-enable it at that point.
