drm/amd/amdgpu: fix offset into page with amdgpu_iomem debugfs file

2018-03-21T04:43:34Z

The offset inside the page wasn't included in the copy call meaning the start of the page was being read/written instead. Reported-by: Jay Cornwall Signed-off-by: Tom St Denis Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: explicit give BO type to amdgpu_bo_create

2018-03-14T20:08:24Z

Drop the "kernel" and sg parameter and give the BO type to create explicit to amdgpu_bo_create instead of figuring it out from the parameters. Signed-off-by: Christian König Reviewed-by: Roger He Signed-off-by: Alex Deucher

drm/amdgpu: drop the backing store when DMA-buf imports are evicted

2018-03-14T19:38:28Z

Instead of moving this to the SYSTEM domain just drop the backing store and let the resulting allocation be freed. Signed-off-by: Christian König Acked-by: Roger He Signed-off-by: Alex Deucher

drm/ttm: add bo as parameter to the ttm_tt_create callback

2018-03-14T19:38:27Z

Instead of calculating the size in bytes just to recalculate the number of pages from it pass the BO directly to the function. Signed-off-by: Christian König Reviewed-by: Roger He Signed-off-by: Alex Deucher

drm/amdgpu: stop allocating a page array for prime shared BOs

2018-03-14T19:38:24Z

We don't need the page array for prime shared BOs, stop allocating it. Signed-off-by: Christian König Reviewed-by: Roger He Signed-off-by: Alex Deucher

drm/amdgpu: Add GPUVM memory management functions for KFD

2018-02-07T01:32:38Z

v2: * Removed unused flags from struct kgd_mem * Updated some comments * Added a check to unmap_memory_from_gpu whether BO was mapped v3: add mutex_destroy in relevant places Signed-off-by: Felix Kuehling Acked-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdgpu: Add KFD eviction fence

2018-02-07T01:32:35Z

This fence is used by KFD to keep memory resident while user mode queues are enabled. Trying to evict memory will trigger the enable_signaling callback, which starts a KFD eviction, which involves preempting user mode queues before signaling the fence. There is one such fence per process. v2: * Grab a reference to mm_struct * Dereference fence after NULL check * Simplify fence release, no need to signal without anyone waiting * Added signed-off-by Harish, who is the original author of this code v3: * update MAINTAINERS file * change amd_kfd_ prefix to amdkfd_ * remove useless initialization of variable to NULL v4: * set amdkfd_fence_ops to be static * Suggested by: Fengguang Wu Signed-off-by: Harish Kasiviswanathan Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdgpu: replace iova debugfs file with iomem (v3)

2018-03-07T21:11:54Z

This allows access to pages allocated through the driver with optional IOMMU mapping. v2: Fix number of bytes copied and add write method v3: drop check for kmap return Original-by: Christian König Signed-off-by: Tom St Denis Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: drop gtt->adev

We can use ttm->bdev instead. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: use separate status for buffer funcs availability v2

2018-03-05T20:37:24Z

The ring status can change during GPU reset, but we still need to be able to schedule TTM buffer moves in the meantime. Otherwise we can ran into problems because of aborted move/fill operations during GPU resets. v2: still check if ring is available during direct submit.
