drm/amdgpu: exclude duplicate pages from UMC RAS UE count

2023-02-23T22:35:59Z

If a UMC bad page is reserved but not freed by an application, the application may trigger uncorrectable error repeatly by accessing the page. v2: add specific function to do the check. v3: remove duplicate pages, calculate new added bad page number. v4: reuse save_bad_pages to calculate new added bad page number.

drm/amdgpu: allow query error counters for specific IP block

2023-01-05T16:42:14Z

amdgpu_ras_block_late_init will be invoked in IP specific ras_late_init call as a common helper for all the IP blocks. However, when amdgpu_ras_block_late_init call amdgpu_ras_query_error_count to query ras error counters, amdgpu_ras_query_error_count queries all the IP blocks that support ras query interface. This results to wrong error counters cached in software copies when there are ras errors detected at time zero or warm reset procedure. i.e., in sdma_ras_late_init phase, it counts on sdma/mmhub errors, while, in mmhub_ras_late_init phase, it still counts on sdma/mmhub errors. The change updates amdgpu_ras_query_error_count interface to allow query specific ip error counter. It introduces a new input parameter: query_info. if query_info is NULL, it means query all the IP blocks, otherwise, only query the ip block specified by query_info.
