So I googled a bit, but not completely sure. Is this only useful for openGL since it's RadeonSI? Or does the amd/common stuff also gets used by RADV?

Yeah, it is a common backend. Radv and RadeonSI both share as much as is possible. It's the reason why RadeonSI took years to bring up, but Radv was up in a very short time.

Pretty sure it's currently only used by OpenGL, but by moving this code into common radv might soon start using it as well.
