2024-01-16drm/amdgpu: check PS, WS indexAlexander Richards1-2/+2
Theoretically, it would be possible for a buggy or malicious VBIOS to overwrite past the bounds of the passed parameters (or its own workspace); add bounds checking to prevent this from happening.

2020-08-14drm/amd/pm: optimize the power related source code layoutEvan Quan1-0/+710
The target is to provide a clear entry point(for power routines). Also this can help to maintain a clear view about the frameworks used on different ASICs. Hopefully all these can make power part more friendly to play with.
