I see you have nouveau.config=PCRYPT=0 in your kernel config. Why did you add
this -- was there some kind of issue with the engine? Did someone in #nouveau
tell you to do it to help some issue? It's normally used for copy acceleration
on G96 (which would, in turn, be used to copy off any vram data to ram on
suspend).
The reason I ask is that starting with kernel 4.3, that will no longer have the
effect of disabling PCRYPT. The new config to achieve that would be
nouveau.config=cipher=0.
Note that for G96, I don't think anything in firmware-misc-nonfree would affect
it either way.

Hello Ilia,
I had found a bug report (https://bugs.freedesktop.org/show_bug.cgi?id=58378)
dealing with a similar issue, and there you suggested to try that option
(https://bugs.freedesktop.org/show_bug.cgi?id=58378#c46), and it seemingly
solved the issue, so I gave it a try, but removed it after I noticed that it
had no effect at all.

Ok, thanks for clarification. Copy acceleration sounds good, is there any
downside?

I will uninstall that package and report back.
BTW: No problems with 5.4.13 so far.

Well, the problem the other users were having is that their GPUs were actually
missing the crypt engine entirely, and we were not properly reading the
capabilities bits that indicated this. Trying to use the crypt engine when it's
not actually there has some obvious downsides :) But I don't see an indication
that this would be the case on your setup. (First of all, we now respect the
capability bit, and secondly, you don't have any mmio read/write errors in that
range.)

Well, then this might sound strange:
I purged firmware-misc-nonfree, rebooted, sent the system to sleep and resumed,
and the distortion was back.
Instead of reinstalling it, I set nouveau.config=cipher=0 and tested again, and
everything is fine. Furthermore, now I can use the firmware for Video
Acceleration. Before, I always had distortion after resume with that firmware
installed.
So everything seems fine now, but is there any downside in disabling the crypt
engine?

Sounds like there are things going on that we don't quite understand then...
maybe Ben can weigh in.
If the cipher method is disabled (aka CRYPT), it will fall back to M2MF for
copy acceleration. In experiments, this is slightly slower but still
accelerated.

Ok. However, thank you for telling me the right option for disabling the crypt
engine on current kernels.
If you need any logs or want me to do certain tests, let me know.

Follow-up:
After a dist-upgrade, the error returned. I deleted the video acceleration
firmware and it was ok again.
When I installed 5.4.14, there were warnings about possibly missing firmware
(the nvidia files from firmware-misc-nonfree), so I reinstalled that package
and updated the initramfs (I think I missed that step after purging the
package). Furthermore, I removed nouveau.config=cipher=0 since that doesn't
seem to be related to the error.
To conclude: When it works, I do a dist-upgrade one day and the error returns.
Doing a dist-upgrade a few days after makes it work again. The same holds for
kernel upgrades.
