Hi Amarnath,
not a bad idea, but that won't work either because you really need to
return to make sure that a potential next reset can run.
What could be done is to have a work item which does that, but then I
think it would just be easier to teach the udev function a GFP mask.

Hi Christian,
if sending udev event during reset is going to create problem, we can
move this code from reset sequence to re-int (after GPU reset succeeded).
Regards,
S.Amarnath

Any suggestion how we can notify user space during this situation.
Well trace points should work. They use a ring buffer

Alternative would be to audit the udev code and allow givin
