drm/amdkfd: Clean up KFD style errors and warnings v2

2017-08-16T03:00:04Z

Using checkpatch.pl -f showed a number of style issues. This patch addresses as many of them as possible. Some long lines have been left for readability, but attempts to minimize them have been made. v2: Broke long lines in gfx_v7 get_fw_version Signed-off-by: Kent Russell Signed-off-by: Felix Kuehling Signed-off-by: Oded Gabbay

drm/amdgpu: Fix KFD initialization for multi-GPU systems

2017-08-15T18:46:02Z

kfd2kgd is device-specific, so it should not be a global variable. Merge amdgpu_amdkfd_load_interface and amdgpu_amdkfd_device_probe so that it's only needed as a local variable in one function. Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Alex Deucher

drm/amdgpu: Add a parameter to amdgpu_bo_create()

drm/amdgpu: Fix KFD oversubscription by tracking queues correctly

2017-07-14T01:21:53Z

The number of compute queues available to the KFD was erroneously calculated as 64. Only the first MEC can execute compute queues and it has 32 queue slots. This caused the oversubscription limit to be calculated incorrectly, leading to a missing chained runlist command at the end of an oversubscribed runlist. v2: Remove unused num_mec field to avoid duplicate logic v3: Separate num_mec removal into separate patches Change-Id: I9e7bba2cc1928b624e3eeb1edb06fdb602e5294f Signed-off-by: Jay Cornwall Reviewed-by: Alex Deucher Signed-off-by: Oded Gabbay

drm/amdgpu: avoid KIQ clashing with compute or KFD queues v2

2017-05-31T20:48:58Z

Instead of picking an arbitrary queue for KIQ, search for one according to policy. The queue must be unused. Also report the KIQ as an unavailable resource to KFD. In testing I ran into KCQ initialization issues when using pipes 2/3 of MEC2 for the KIQ. Therefore the policy disallows grabbing one of these. v2: fix (ring.me + 1) to (ring.me -1) in amdgpu_amdkfd_device_init Reviewed-by: Felix Kuehling Signed-off-by: Andres Rodriguez Signed-off-by: Alex Deucher

drm/amdkfd: allow split HQD on per-queue granularity v5

2017-05-31T20:48:54Z

Update the KGD to KFD interface to allow sharing pipes with queue granularity instead of pipe granularity. This allows for more interesting pipe/queue splits. v2: fix overflow check for res.queue_mask v3: fix shift overflow when setting res.queue_mask v4: fix comment in is_pipeline_enabled() v5: clamp res.queue_mask to the first MEC only Reviewed-by: Edward O'Callaghan Reviewed-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Andres Rodriguez Signed-off-by: Alex Deucher
