drm/amdgpu: fix "mitigate workaround for i915"

2018-03-21T20:04:03Z

Mixed up exporter and importer here. E.g. while mapping the BO we need to check the importer not the exporter. Bug: https://bugs.freedesktop.org/show_bug.cgi?id=105633 Signed-off-by: Christian König Acked-by: Alex Deucher Tested-by: Mike Lothian 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: initial validate the prime BOs into the CPU domain

2018-03-14T19:38:28Z

Just set the GTT domain as mandatory, so that the BO is validated into it on first use. This allows us to setup the sg table later on. Signed-off-by: Christian König Acked-by: Roger He Signed-off-by: Alex Deucher

drm/amdgpu: further mitigate workaround for i915

2018-03-07T21:10:12Z

Disable the workaround on imported BOs as well. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: mitigate workaround for i915

2018-02-20T19:40:13Z

To be able to use DRI_PRIME with amdgpu and i915 we add all our fences only as exclusive ones. Disable that behavior when sharing between amdgpu itself cause it hinders concurrent execution. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: implement amdgpu_gem_map_(attach/detach)

2018-02-20T19:40:03Z

Instead of the pin/unpin callback implement the attach/detach ones. Functional identical, but allows us access to the attachment. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: revert "Add a parameter to amdgpu_bo_create()"

2018-02-19T19:18:54Z

This reverts commit 2046d46db9166bddc84778f0b3477f6d1e9068ea. Not needed any more. Signed-off-by: Christian König Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Move to gtt before cpu accesses dma buf.

2018-02-19T19:17:41Z

To improve cpu read performance. This is implemented for APUs currently. v2: Adapt to change https://lists.freedesktop.org/archives/amd-gfx/2017-October/015174.html v3: Adapt to change "forward begin_cpu_access callback to drivers" v4: Instead of v3, reuse drm_gem dmabuf_ops here. Also some minor fixes as suggested. v5: only set dma_buf ops when it is valid (Samuel) Signed-off-by: Samuel Li Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: set f_mapping on exported DMA-bufs

2017-11-14T16:35:43Z

Otherwise we can't correctly CPU map TTM buffers. Signed-off-by: Christian König Acked-by: Alex Deucher Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/amdgpu: Add gem_prime_mmap support

2017-09-26T19:14:37Z

v2: drop hdp invalidate/flush. v3: honor pgoff during prime mmap. Add a barrier after cpu access. v4: drop begin/end_cpu_access() for now, revisit later. Signed-off-by: Samuel Li Reviewed-by: Christian König Signed-off-by: Alex Deucher
