drm/amdkfd: Optimize out sdma doorbell array in kgd2kfd_shared_resources

2019-02-18T23:00:50Z

We can directly calculate sdma doorbell indexes in the process doorbell pages through the doorbell_index structure in amdgpu_device, so no need to cache them in kgd2kfd_shared_resources any more. This alleviates the adaptation needs when new SDMA configurations are introduced. Signed-off-by: Yong Zhao Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Fix bugs regarding CP queue doorbell mask on SOC15

drm/amdgpu: Relocate kgd2kfd function declaration

2019-01-14T20:04:28Z

Since amdkfd is merged into amdgpu module and amdgpu can access amdkfd directly, move declaration of kgd2kfd functions from kfd_priv.h to amdgpu_amdkfd.h Signed-off-by: Amber Lin Reviewed-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Alex Deucher

drm/amdkfd: Add support for doorbell BOs

2018-12-07T23:14:00Z

This allows user mode to map doorbell pages into GPUVM address space. That way GPUs can submit to user mode queues (self-dispatch). Acked-by: Alex Deucher Signed-off-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Change the control stack MTYPE from UC to NC on GFX9

2018-09-20T15:25:17Z

CWSR fails on Raven if the control stack is MTYPE_UC, which is used for regular GART mappings. As a workaround we map it using MTYPE_NC. The MEC firmware expects the control stack at one page offset from the start of the MQD so it is part of the MQD allocation on GFXv9. AMDGPU added a memory allocation flag just for this purpose.
