> Next week, at embedded world, we will be giving a restartability demo (running on ARM) of the crash and recovery of a graphics driver. This is quite unique and unseen feature in the Linux world.
Uhm...

Linux GPU drivers have had support for hang detection and reset for _years_.

hehe.

It seems that the biggest problem with all of this is that when the driver crashes it puts the hardware into a bad state were recovery is just not going to happen.

That is why I suppose people don't notice that hang detection and reset exists.

Oops inside kernel driver was always either-or event.
If you're lucky, kernel continues to run, no restart needed!
