... instead of looping endless with no hope of ever serving that page-fault. We only need to break out of this loop when the gpu died, to run the reset work (and hopefully resurrect it). To clarify questions Chris raised on irc: This is about handling I/O errors not from our own code, but e.g. when the disk died when trying to swap in a gem bo. So this patch remidies the issue that the current handling only handles gpu-death-induced cases of -EIO. Admittedly, dying disks are much rarer than hanging gpus ...To clarify questions Chris raised on irc: This is about handling I/O errors not from our own code, but e.g. when the disk died when trying to swap in a gem bo.
