2018-09-12drm/amdgpu: try allocating VRAM as power of twoChristian König
Try to allocate VRAM in power of two sizes and only fallback to vram split sizes if that fails. Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Felix Kuehling <felix.kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2018-07-13drm/amdgpu: Keep track of amount of pinned CPU visible VRAMMichel Dänzer
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 <christian.koenig@amd.com> Signed-off-by: Michel Dänzer <michel.daenzer@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2018-06-19drm/amdgpu: Make amdgpu_vram_mgr_bo_invisible_size always accurateMichel Dänzer
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.

2018-06-19drm/amdgpu: Use kvmalloc_array for allocating VRAM manager nodes arrayMichel Dänzer
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).

2017-02-03drm: Improve drm_mm search (and fix topdown allocation) with rbtreesChris Wilson
The drm_mm range manager claimed to support top-down insertion, but it was neither searching for the top-most hole that could fit the allocation request nor fitting the request to the hole correctly. In order to search the range efficiently, we create a secondary index for the holes using either their size or their address. This index allows us to find the smallest hole or the hole at the bottom or top of the range efficiently, whilst keeping the hole stack to rapidly service evictions. v2: Search for holes both high and low. Rename flags to mode. v3: Discover rb_entry_safe() and use it! v4: Kerneldoc for enum drm_mm_insert_mode.

2016-12-30drm/mm: Convert to drm_printerDaniel Vetter
Including all drivers. I thought about keeping small compat functions to avoid having to change all drivers. But I really like the drm_printer idea, so figured spreading it more widely is a good thing. v2: Review from Chris: - Natural argument order and better name for drm_mm_print. - show_mm() macro in the selftest.
