2019-08-27drm/amdgpu: Add RAS EEPROM table.Andrey Grodzovsky1-0/+3
Add RAS EEPROM table manager to eanble RAS errors to be stored upon appearance and retrived on driver load. v2: Fix some prints. v3: Fix checksum calculation. Make table record and header structs packed to do correct byte value sum. Fix record crossing EEPROM page boundry. v4: Fix byte sum val calculation for record - look at sizeof(record). Fix some style comments. v5: Add description to EEPROM_TABLE_RECORD_SIZE and syntax fixes.

2019-06-13amdgpu: no need to check return value of debugfs_create functionsGreg Kroah-Hartman1-2/+2
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

2019-06-11drm/amdgpu: Fix bounds checking in amdgpu_ras_is_supported()Dan Carpenter1-0/+2
The "block" variable can be set by the user through debugfs, so it can be quite large which leads to shift wrapping here. This means we report a "block" as supported when it's not, and that leads to array overflows later on. This bug is not really a security issue in real life, because debugfs is generally root only.

2019-03-19drm/amdgpu: add new ras workflow control flagsxinhui pan1-0/+3
add ras post init function. Do some initialization after all IP have finished their late init. Add new member flags which will control the ras work flow. For now, vbios enable ras for us on boot. That might change in the future. So there should be a flag from vbios to tell us if ras is enabled or not on boot. Looks like there is no such info now. Other bits of the flags are reserved to control other parts of ras.
