2021-07-13drm/amdgpu: Return error if no RASLuben Tuikov1-14/+35
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: Fix RAS function interfaceLuben Tuikov1-8/+15
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.

Add bad_page_cnt_threshold to debugfs, an optional file system used for debugging, for reporting purposes only--it usually matches the size of EEPROM but may be different depending on the "bad_page_threshold" kernel module option. The "bad_page_cnt_threshold" is a dynamically computed value. It depends on three things: the VRAM size; the size of the EEPROM (or the size allocated to the RAS table therein); and the "bad_page_threshold" module parameter. It is a dynamically computed value, when the amdgpu module is run, on which further parameters and logic depend, and as such it is helpful to see the dynamically computed value in debugfs.

2021-04-15drm/amdgpu: Fix a bug for input with double sscanfLuben Tuikov1-8/+5
Remove double-sscanf to scan for %llu and 0x%llx, as that is not going to work! The %llu will consume the "0" in "0x" of your input, and the hex value you think you're entering will always be 0. That is, a valid hex value can never be consumed. On the other hand, just entering a hex number without leading 0x will either be scanned as a string and not match, for instance FAB123, or the leading decimal portion is scanned as the %llu, for instance 123FAB will be scanned as 123, which is not correct. Thus remove the first %llu scan and leave only the %llx scan, removing the leading 0x since %llx can scan either. Addresses are usually always hex values, so this suffices.

2021-03-23drm/amdgpu: fix send ras disable cmd when asic not support rasStanley.Yang1-11/+46
cause: It is necessary to send ras disable command to ras-ta during gfx block ras later init, because the ras capability is disable read from vbios for vega20 gaming, but the ras context is released during ras init process, this will cause send ras disable command to ras-to failed. how: Delay releasing ras context, the ras context will be released after gfx block later init done. Changed from V1: move release_ras_context into ras_resume Changed from V2: check BIT(UMC) is more reasonable before access eeprom table Signed-off-by: Stanley.Yang <Stanley.Yang@amd.com> Reviewed-by: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

When connected to a host via xGMI, system fatal errors may trigger warm reset, driver has no change to query edc status before reset. Therefore in this case, driver should harvest previous error loging registers during boot, instead of only resetting them. v2: 1. IP's ras_manager object is created when its ras feature is enabled, so change to query edc status after amdgpu_ras_late_init called 2. change to enable watchdog timer after finishing gfx edc init Signed-off-by: Dennis Li <Dennis.Li@amd.com> Reivewed-by: Hawking Zhang <hawking.zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
