drm/amdgpu: Use reset recovery state checks

2024-11-20T15:03:05+00:00

Some in_reset checks are infact checking whether the state is reinitialization after reset. Replace with reset_in_recovery calls to identify that it's really checking for recovery stage after reset. Signed-off-by: Lijo Lazar Acked-by: Tao Zhou Signed-off-by: Alex Deucher

drm/amdgpu: Implement virt req_ras_err_count

2024-11-11T16:55:42+00:00

Enable RAS late init if VF RAS Telemetry is supported. When enabled, the VF can use this interface to query total RAS error counts from the host. The VF FB access may abruptly end due to a fatal error, therefore the VF must cache and sanitize the input. The Host allows 15 Telemetry messages every 60 seconds, afterwhich the host will ignore any more in-coming telemetry messages. The VF will rate limit its msg calling to once every 5 seconds (12 times in 60 seconds). While the VF is rate limited, it will continue to report the last good cached data. v2: Flip generate report & update statistics order for VF Signed-off-by: Victor Skvortsov Acked-by: Tao Zhou Reviewed-by: Zhigang Luo Signed-off-by: Alex Deucher

drm/amdgpu: VF Query RAS Caps from Host if supported

2024-11-11T16:55:36+00:00

If VF RAS Capability support is enabled, guest is able to retrieve the real RAS support from the host. Signed-off-by: Victor Skvortsov Reviewed-by: Zhigang Luo Signed-off-by: Alex Deucher

drm/amdgpu: Skip IP coredump for RAS errors

2024-11-04T17:06:23+00:00

For RAS errors, source of error is known. Skip the core dump of IP states. Signed-off-by: Lijo Lazar Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher

drm/amdgpu: Refactor XGMI reset on init handling

2024-09-26T21:06:46+00:00

Use XGMI hive information to rely on resetting XGMI devices on initialization rather than using mgpu structure. mgpu structure may have other devices as well. Signed-off-by: Lijo Lazar Reviewed-by: Feifei Xu Acked-by: Rajneesh Bhardwaj Tested-by: Rajneesh Bhardwaj Signed-off-by: Alex Deucher

drm/amdgpu: Add helper to initialize badpage info

2024-09-26T21:06:38+00:00

Add a separate function to read badpage data during initialization. Reading bad pages will need hardware access and cannot be done during reset. Hence in cases where device needs a full reset during init itself, attempting to read will cause a deadlock.

drm/amdgpu: Use init level for pending_reset flag

Drop pending_reset flag in gmc block. Instead use init level to determine which type of init is preferred - in this case MINIMAL. Signed-off-by: Lijo Lazar Acked-by: Rajneesh Bhardwaj Tested-by: Rajneesh Bhardwaj Signed-off-by: Alex Deucher

amd/amdgpu: Reduce unnecessary repetitive GPU resets
