drm/amdkfd: use tlb_seq from the VM subsystem for SVM as well v2

2022-03-25T16:40:52+00:00

Instead of hand rolling the table_freed parameter. v2: add some changes suggested by Philip Signed-off-by: Christian König Reviewed-by: Philip Yang Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: add UTCL2 RAS poison query for Aldebaran (v2)

2022-03-25T16:40:26+00:00

Add help functions to query and reset RAS UTCL2 poison status. v2: implement it on amdgpu side and kfd only calls it. Signed-off-by: Tao Zhou Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher

drm/amdkfd: CRIU Implement KFD resume ioctl

2022-02-07T22:59:41+00:00

This adds support to create userptr BOs on restore and introduces a new ioctl op to restart memory notifiers for the restored userptr BOs. When doing CRIU restore MMU notifications can happen anytime after we call amdgpu_mn_register. Prevent MMU notifications until we reach stage-4 of the restore process i.e. criu_resume ioctl op is received, and the process is ready to be resumed. This ioctl is different from other KFD CRIU ioctls since its called by CRIU master restore process for all the target processes being resumed by CRIU.

drm/amdkfd: CRIU Implement KFD checkpoint ioctl

2022-02-07T22:59:29+00:00

This adds support to discover the buffer objects that belong to a process being checkpointed. The data corresponding to these buffer objects is returned to user space plugin running under criu master context which then stores this info to recreate these buffer objects during a restore operation.

drm/amdkfd: reset queue which consumes RAS poison (v2)

2021-12-28T21:02:59+00:00

CP supports unmap queue with reset mode which only destroys specific queue without affecting others. Replacing whole gpu reset with reset queue mode for RAS poison consumption saves much time, and we can also fallback to gpu reset solution if reset queue fails. v2: Return directly if process is NULL; Reset queue solution is not applicable to SDMA, fallback to legacy way; Call kfd_unref_process after lookup process.

drm/amdgpu: Update BO memory accounting to rely on allocation flag

2021-11-22T19:45:01+00:00

Accounting system to track amount of available memory (system, TTM and VRAM of a device) relies on BO's domain. The change is to rely instead on allocation flag indicating BO type - VRAM, GTT, USERPTR, MMIO or DOORBELL Signed-off-by: Ramesh Errabolu Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher
