drm/amdgpu: kfd_pre_reset outside req_full_gpu cause sriov hang

2018-12-14T17:04:38Z

XGMI hive put kfd_pre_reset into amdgpu_device_lock_adev, but outside req_full_gpu of sriov. It would make sriov hang during reset. Signed-off-by: Wentao Lou Reviewed-by: Shaoyun Liu Signed-off-by: Alex Deucher

drm/amdgpu: Implement concurrent asic reset for XGMI.

2018-12-03T16:15:14Z

Use per hive wq to concurrently send reset commands to all nodes in the hive. v2: Switch to system_highpri_wq after dropping dedicated queue. Fix non XGMI code path KASAN error. Stop the hive reset for each node loop if there is a reset failure on any of the nodes. Signed-off-by: Andrey Grodzovsky Acked-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: Fix num_doorbell calculation issue

2018-11-30T17:01:04Z

When paging queue is enabled, it use the second page of doorbell. The AMDGPU_DOORBELL64_MAX_ASSIGNMENT definition assumes all the kernel doorbells are in the first page. So with paging queue enabled, the total kernel doorbell range should be original num_doorbell plus one page (0x400 in dword), not *2.

drm/amdgpu: Refactor GPU reset for XGMI hive case

2018-11-28T20:55:36Z

For XGMI hive case do reset in steps where each step iterates over all devs in hive. This especially important for asic reset since all PSP FW in hive must come up within a limited time (around 1 sec) to properply negotiate the link. Do this by refactoring amdgpu_device_gpu_recover and amdgpu_device_reset into pre_asic_reset, asic_reset and post_asic_reset functions where is part is exectued for all the GPUs in the hive before going to the next step. v2: Update names for amdgpu_device_lock/unlock functions. v3: Introduce per hive locking to avoid multiple resets for GPUs in same hive. v4: Remove delayed_workqueue()/ttm_bo_unlock_delayed_workqueue() - they are copy & pasted over from radeon and on amdgpu there isn't any reason for that any more.
