drm/amdgpu: try allocating VRAM as power of two

2018-09-12T21:28:28Z

Try to allocate VRAM in power of two sizes and only fallback to vram split sizes if that fails. Signed-off-by: Christian König Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Keep track of amount of pinned CPU visible VRAM

2018-07-13T19:46:11Z

Instead of CPU invisible VRAM. Preparation for the following, no functional change intended. v2: * Also change amdgpu_vram_mgr_bo_invisible_size to amdgpu_vram_mgr_bo_visible_size, allowing further simplification (Christian König) Cc: stable@vger.kernel.org Reviewed-by: Christian König Signed-off-by: Michel Dänzer Signed-off-by: Alex Deucher

drm/amdgpu: Make amdgpu_vram_mgr_bo_invisible_size always accurate

2018-06-19T18:51:45Z

Even BOs with AMDGPU_GEM_CREATE_NO_CPU_ACCESS may end up at least partially in CPU visible VRAM, in particular when all VRAM is visible. v2: * Don't take VRAM mgr spinlock, not needed (Christian König) * Make loop logic simpler and clearer.

drm/amdgpu: Use kvmalloc_array for allocating VRAM manager nodes array

2018-06-19T17:43:27Z

It can be quite big, and there's no need for it to be physically contiguous. This is less likely to fail under memory pressure (has actually happened while running piglit). Cc: stable@vger.kernel.org Signed-off-by: Michel Dänzer Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu:fix memleak in takedown

2017-11-16T18:35:48Z

this can fix the memory leak under the case that not all BO are freed during "takedown" stage, because originally it blocks following kfree on mgr. Signed-off-by: Monk Liu Reviewed-by: Christian König Signed-off-by: Alex Deucher
