Not a problem with this patch because we're moving code around, but this is a potential infinite loop that should have some sort of timeout so we don't sit here forever trying to see a bit toggle.
Yes, I will add some protection in new patch, like it is done for newer PLLs. Thanks for you review. -- Regards, Sylwester _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
