Yeah, but iirc we've hand-waved over the issue with "hopefully the bios wm setup never underruns while we take over". If it does we're screwed ;-) Wrt vblank interrupts I think we're better off since we initially disable them, and only enable them on-demand. Presuming that our interrupt setup code is race-free and properly clears out old interrupts we should be fine here. So I'm ok with just mentioning that in the commit message. For the pipe underrun stuff I guess we could to disable the relevant interrupt sources at driver bring up first, but maybe we can just wait with that until the first bug report hits us ;-) Cheers, Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
