I am intrigued as to how the rings can be active when they are shut down. Oh, I see, a slight misordering... Can you please also send a patch to issue the ring disable before we setup the status page? I wonder if there are other steps that should be placed into that critical section where the ring is disabled? -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
