* drm/amdgpu: Use active umc info from discoveryLijo Lazar2025-02-131-0/+42
| | | | | | | | | | | | | | There could be configs where some UMC instances are harvested. This information is obtained through discovery data and populated in umc.active_mask. Avoid reassigning this as AID mask, instead use the mask directly while iterating through umc instances. This is to avoid accesses to harvested UMC instances. v2: fix warning (Alex) Signed-off-by: Lijo Lazar <[email protected]> Reviewed-by: Hawking Zhang <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
* drm/amdgpu: correct the calculation of RAS bad pageTao Zhou2024-12-101-1/+2
| | | | | | | | | | After the introduction of NPS RAS, one bad page record on eeprom may be related to 1 or 16 bad pages, so the bad page record and bad page are two different concepts, define a new variable to store bad page number.

* drm/amdgpu: parse legacy RAS bad page mixed with new data in various NPS modesTao Zhou2024-12-101-2/+2
| | | | | | | | | | | | All legacy RAS bad pages are generated in NPS1 mode, but new bad page can be generated in any NPS mode, so we can't use retired_page stored on eeprom directly in non-nps1 mode even for legacy data. We need to take different actions for different data, new data can be identified from old data by UMC_CHANNEL_IDX_V2 flag.

* drm/amdgpu: Implement virt req_ras_err_countVictor Skvortsov2024-11-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | 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 <[email protected]> Acked-by: Tao Zhou <[email protected]> Reviewed-by: Zhigang Luo <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
