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.

Many parts of the whole SW stack can program the ras enablement state during the boot. Now we handle that case by adding one function which check the ras flags and choose different code path.

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.
