Looks like if we error out somewhere we never have before, and the attempt to
clean things up ends up using something that hasn't been initialized yet. Can
you try booting with nouveau.debug=trace to see where we end up going wrong,
which should hopefully point out the bad piece of code wrt error recovery?

That sounds way over the scope of a GSoC.

Yes, this is definitely more doable! Being able to run frameretracer on
nouveau would be ideal, as it is an impressive tool to debug performance
issue on Intel platforms (and it may already somewhat work).

Well, I know you are optimistic, but that sounds impossible to someone
who is not already a contributor!

Yes, that could be a good one. This is a pretty self-contained project.
Not sure this is what we want to be working towards, but anything we can
do to reduce our workload is appreciated :)

I would rather go for implementing a lot of simple ones, and hope that
the student will stay long enough to get to the useful ones ;)

Big enough? It is big-enough for a decade apparently given how slow we
have been :s

Thanks for doing this, we need to get more contributors, and this is the
first step!

[Nouveau] [Bug 103284] New: Unable to handle kernel NULL pointer dereference on 4.13.0-1-sparc64-smp

2017-10-15 Thread bugzilla-daemon

Bug ID: 103284
   Summary: Unable to handle kernel NULL pointer dereference on
4.13.0-1-sparc64-smp
   Product: xorg
   Version: unspecified
  Hardware: Other
OS: All
Status: NEW
  Severity: normal
  Priority: medium
 Component: Driver/nouveau
  Assignee: nouveau@lists.freedesktop.org
  Reporter: theholyet...@googlemail.com
QA Contact: xorg-t...@lists.x.org

Created attachment 134850
  --> https://bugs.freedesktop.org/attachment.cgi?id=134850=edit
dmesg with oops

dmesg output attached.

I'll admit this is a somewhat bizarre hardware combination (PC GeForce 210 card
in a Sun Ultra 45), but it probably shouldn't Oops on a null pointer.

More like "distro error" -- "listened to the cacophony of people saying
modesetting is the way to go".

The real issue is that there's some issue in the GL, hence the display issues.
Now they will be limited to applications that use GL [which sadly is "a lot"
these days].

The problems are all gone.

Please chalk this up to user error
- did not configure Xorg to use the nouveau driver.
