drm/amdkfd: SMI report dropped event count2024-10-07T18:32:23+00:00Philip YangPhilip.Yang@amd.com2024-07-30T19:33:23+00:00urn:sha1:a3ab2d45b9887ee609cd3bea39f668236935774c
Add new SMI event to report the dropped event count.
When the event kfifo is full, drop count is not zero, or no enough space
left to store the event message, increase drop count.
After reading event out from kfifo, if event was dropped, drop_count is
not zero, generate a dropped event record and reset drop count to zero.

drm/amdkfd: Output migrate end event if migrate failed2024-10-07T18:09:02+00:00Philip YangPhilip.Yang@amd.com2024-02-16T16:41:16+00:00urn:sha1:dad6c45cbd40b57db95c9d46e01ff6d302e86042
If page migration failed, also output migrate end event to match with
migrate start event, with failure error_code added to the end of the
migrate message macro. This will not break uAPI because application uses
old message macro sscanf drop and ignore the error_code.
Output GPU page fault restore end event if migration failed.

Certain GPUs have better copy performance over xGMI on specific
SDMA engines depending on the source and destination GPU.
Allow users to create SDMA queues on these recommended engines.
Close to 2x overall performance has been observed with this
optimization.
