Nouveau - Feb 2010 - [Bug 26555] New: nouveau fails to fully resume nforce1 (nv1a) after S3

http://bugs.freedesktop.org/show_bug.cgi?id=26555

           Summary: nouveau fails to fully resume nforce1 (nv1a) after S3
           Product: xorg
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: bonbons67 at internet.lu

Kernel log for both scenarios (debug messages not captured)

Nouveau fails to fully resume from suspend to ram complaining with "PFIFO
still
angry after 101 spins" and monitor just shows garbage (advertised fallback
software fbcon seems not to work). All is done with KMS on linux console,
without running X.

02:00.0 VGA compatible controller [0300]: nVidia Corporation NVCrush11
        [GeForce2 MX Integrated Graphics] [10de:01a0] (rev b1)
(see bug #25619 for full lspci)

kernel version used: 2.6.33-rc8 from Linus + commit
d5f669822059651c4db1be94cbab605e1ba5a389 from nouveau/master.


I tried the following approaches, all ending at the same state:

suspend with nouveau loaded, it POSTs the GPU (which causes monitor to display
"colorful flickering text console") and after doing modesetting
displays
garbage and complains about the angry PFIFO.

suspend while unloading nouveau before suspend and loading it after resume (not
runing vbetool or anything special between resume and loading nouveau), in this
case system resumes quickly without graphics, nouveau then hits the same issues
as when it's resuming (though without POSTing GPU).

In either case switching back from nouveau to text console ends in the
"colorful flickering text console" (back to nouveau after that does
not help
either).

It looks like either something is done in the wrong order or is missing for the
GPU to get things done right.


Is there anything additional I could provide to help getting the resume
working properly?

--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
It appears that this bug report has laid dormant for quite a while. Sorry we
haven't gotten to it. Since we fix bugs all the time, chances are pretty
good
that your issue has been fixed with the latest software. Please give it a shot.
(Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git
versions.) If upgrading to the latest isn't an option for you, your
distro's
bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs
that haven't seen updates since 2011. If the original issue remains, please
make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/
for what we need to see, and re-open this one.

Thanks,

The Nouveau Team

This still applies to 3.10.7.

Hard to tell what state GPU is in as monitor sees no signal after loading
nouveau.

This still applies, with patches (attachment 84758 from bug #50375, or
attachment 85214 and attachment 85215 from bug #50375) applied.

One one attempt with first patch applied on top of 3.11 I got some more-or-less
tiled pattern with black tile content and random borders (big tiles).

One one attempt with the set of two patches I got rather uniform noise.

Writing to /dev/fb0 (from /dev/zero or /dev/urandom) does not seem to affect
the noise displayed on the monitor.
