introduced "ras_err_info" to better identify a RAS ERROR source. NOTE: For legacy chips, keep the original RAS error print format. v1: RAS errors may come from different dies during a RAS error query, therefore, need a new data structure to identify the source of RAS ERROR. v2: - use new data structure 'amdgpu_smuio_mcm_config_info' instead of ras_err_id (in v1 patch) - refine ras error dump function name - refine ras error dump log format Signed-off-by: Yang Wang <kevinyang.wang@amd.com> Reviewed-by: Tao Zhou <tao.zhou1@amd.com> Reviewed-by: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2023-10-13drm/amdgpu: make err_data structure built-in for ras_managerYang Wang
(No effect outside the ras_mgr data structure) Since a new member was added to the ras_err_data data structure, it becomes unreasonable for the ras_mgr instance to contain this data, because ras mgr only uses the 2 member information of ue_count/ce_count in err_data. This patch changes the code err_data into built-in structure members, making the code directly compatible.

2023-01-05drm/amdgpu: allow query error counters for specific IP blockHawking Zhang
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.

In amdgpu_ras_query_error_count() return an error if the device doesn't support RAS. This prevents that function from having to always set the values of the integer pointers (if set), and thus prevents function side effects--always to have to set values of integers if integer pointers set, regardless of whether RAS is supported or not--with this change this side effect is mitigated. Also, if no pointers are set, don't count, since we've no way of reporting the counts. Also, give this function a kernel-doc.

2021-05-27drm/amdgpu: Use delayed work to collect RAS error countersLuben Tuikov
On Context Query2 IOCTL return the correctable and uncorrectable errors in O(1) fashion, from cached values, and schedule a delayed work function to calculate and cache them for the next such IOCTL. v2: Cancel pending delayed work at ras_fini(). v3: Remove conditionals when dealing with delayed work manipulation as they're inherently racy.

2021-05-27drm/amdgpu: Fix RAS function interfaceLuben Tuikov
The correctable and uncorrectable errors are calculated at each invocation of this function. Therefore, it is highly inefficient to return just one of them based on a Boolean input. If the caller wants both, twice the work would be done. (And this work is O(n^3) on Vega20.) Fix this "interface" to simply return what it had calculated--both values. Let the caller choose what it wants to record, inspect, use.

Rename, ras_hw_supported --> ras_hw_enabled, and ras_features --> ras_enabled, to show that ras_enabled is a subset of ras_hw_enabled, which itself is a subset of the ASIC capability.
