I don't think that should block getting the vblank worker code in along with the trivial change to the sprite code to avoid a wait_vblank in the buffer switching case. We've needed that since this code went in, but for some reason Chris's code has been stalled the whole time (and didn't we have a wq patch for the sprite unpin even before that?). -- Jesse Barnes, Intel Open Source Technology Center _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
