Er, hopefully you don't notice anything except it speeds up certain operations (quite considerably) :). You have to enable the DBG output to see it in action, as it is quite a lowlevel feature (i.e. how we interact with the kernel) and should not add any user visible features. However, it does also require the kernel patch for it to be enabled. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
