It's the interface for accessing vram via the CPU. E.g., when you access a buffer in vram via the PCI FB BAR, it goes through the HDP on the GPU. Unfortunately, bugzilla.kernel.org is down so I don't remember exactly what bug the r600_ioctl_wait_idle patch fixed. It's possible you just aren't hitting the case in your particular desktop scenario, but that removing it would regress other cases. I'm leery of applying it until I have some confirmation that someone else is hitting this bug or that it doesn't regress any other cases. > > I tried to compile mesa from git, but didn't succeed and gave up in shame!
