So I've just been looking a bit more at dynamic PM for graphics and noticed that when userspace reads pci config space, the read happens under the pci_lock which is a spinlock. Now on most of the GPU drivers we'll be entering standard s/r paths which don't have this restriction from what I can see, I get to see lots of scheduling while atomic fun, that I'm not really sure I can fix nicely.
