Re: How can I preserve the dump from a GPU hang through reboot?

As upstream stated that was the fix and the firmware package required is in linux-firmware would open a bug report against the linux package asking for https://git.kernel.org/pub/scm/linux/ke … 289cf16703 to be applied.

Re: How can I preserve the dump from a GPU hang through reboot?

Today is the first time this happened while I was actively using the machine i.e. no low-power state was involved and I was in the middle of typing.

It is also the first time I've tested my wait and reboot if dmesg says ... trigger. This worked fine, though rebooting in the middle of doing something is not especially convenient yikes.

Re: How can I preserve the dump from a GPU hang through reboot?

Is there any way to tell whether this or when this will make it into the kernel? My backport request is not doing much, as far as I can tell. (I guess this is an issue which affects few people, so not terribly high priority).

And/or is there anything I can do short of rebooting as a workaround?

Re: How can I preserve the dump from a GPU hang through reboot?

Seems to be in 4.16 - ie. likely next week or so (depends on how long that release remains in testing)

4.16 is not compatible with the nvidia driver so it may remain is staging until arch decides what patches to use or there is a new upstream release from nvidia.

Re: How can I preserve the dump from a GPU hang through reboot?

So this is in the current kernel? That is, I've got 4.16.13-2, but I'm not sure how to be certain this is included. I don't understand how to figure this out from upstream's git repository. (I can see it is merged into master, but I'm not sure if that is the development branch or not and that commit seems only 5 days old.) Or am I even looking at the right thing? https://git.kernel.org/pub/scm/linux/ke … it/commit/
