2021-04-15drm/amdgpu: Add double-sscanf but invertLuben Tuikov
Add back the double-sscanf so that both decimal and hexadecimal values could be read in, but this time invert the scan so that hexadecimal format with a leading 0x is tried first, and if that fails, then try decimal format. Also use a logical-AND instead of nesting double if-conditional.

2021-04-15drm/amdgpu: Add bad_page_cnt_threshold to debugfsLuben Tuikov
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 in checking the result of reserve pageLuben Tuikov
Fix if (ret) --> if (!ret), a bug, for "retire_page", which caused the kernel to recall the method with *pos == end of file, and that bounced back with error. On the first run, we advanced *pos, but returned 0 back to fs layer, also a bug. Fix the logic of the check of the result of amdgpu_reserve_page_direct()--it is 0 on success, and non-zero on error, not the other way around. This patch fixes this bug.

2021-04-15drm/amdgpu: Fix a bug for input with double sscanfLuben Tuikov
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.

2020-08-24drm/amdgpu: refine codes to avoid reentering GPU recoveryDennis Li
if other threads have holden the reset lock, recovery will fail to try_lock. Therefore we introduce atomic hive->in_reset and adev->in_gpu_reset, to avoid reentering GPU recovery. v2: drop "? true : false" in the definition of amdgpu_in_reset Reviewed-by: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: Dennis Li <Dennis.Li@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2020-08-14drm/amdgpu: fix NULL pointer access issue when unloading driverGuchun Chen
When unloading driver by "modprobe -r amdgpu", one NULL pointer dereference bug occurs in ras debugfs releasing. The cause is the duplicated debugfs_remove, as drm debugfs_root dir has been cleaned up already by drm_minor_unregister.

2020-08-14drm/amdgpu: revert "fix system hang issue during GPU reset"Christian König
The whole approach wasn't thought through till the end. We already had a reset lock like this in the past and it caused the same problems like this one. Completely revert the patch for now and add individual trylock protection to the hardware access functions as necessary. This reverts commit df9c8d1aa278c435c30a69b8f2418b4a52fcb929.
