2019-04-12drm/amdgpu: Set proper function to set xgmi pstateshaoyunl1-1/+12
Driver need to call SMU to set xgmi pstate Signed-off-by: shaoyunl <[email protected]> Reviewed-by: Evan Quan <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
2019-03-27drm/amdgpu: XGMI pstate switch initial supportshaoyunl1-1/+15
Driver vote low to high pstate switch whenever there is an outstanding XGMI mapping request. Driver vote high to low pstate when all the outstanding XGMI mapping is terminated.

2019-03-21drm/amdgpu: revert "XGMI pstate switch initial support"Christian König1-15/+0
This reverts commit 9b638f9751308ae3ae8f28e0c6e9decffd97f5f9. Adding this to the mapping is complete nonsense and the whole implementation looks racy. This patch wasn't thoughtfully reviewed and should be reverted for now.

2019-03-19drm/amdgpu: Add sysfs entries for xgmi hive v2.Andrey Grodzovsky1-3/+142
For each device a file xgmi_device_id is created. On the first device a subdirectory named xgmi_hive_info is created, It contains a file named hive_id and symlinks named node 1-4 linking to each device in the hive. v2: Return error codes instead of '-1' and few misspellings.
