Nouveau - Apr 2014 - [Bug 77371] New: [NVA3] gpu lockup unless noaccel=1

https://bugs.freedesktop.org/show_bug.cgi?id=77371

          Priority: medium
            Bug ID: 77371
          Assignee: nouveau at lists.freedesktop.org
           Summary: [NVA3] gpu lockup unless noaccel=1
        QA Contact: xorg-team at lists.x.org
          Severity: critical
    Classification: Unclassified
                OS: Linux (All)
          Reporter: jw.hendy at gmail.com
          Hardware: x86-64 (AMD64)

dmesg after normal startup on Arch x86_64, prior to startx

System details:

$ uname -a
Linux bigBang 3.14.0-4-ARCH #1 SMP PREEMPT Wed Apr 9 21:11:25 CEST 2014 x86_64
GNU/Linux

$ dmesg | grep -i chipset
[   19.583102] nouveau  [  DEVICE][0000:01:00.0] Chipset: GT215 (NVA3)

$ lspci |grep -i vga
01:00.0 VGA compatible controller: NVIDIA Corporation GT215GLM [Quadro FX
1800M] (rev a2)

Description:

I can only successfully `startx` if I modprobe nouveau with no acceleration
(`nouveau.noaccel=1` appended to kernel line or `options nouveau noaccel=1` in
/etc/modprobe.d/nouveau.conf).

With noaccel=0 (default), I get a GPU lockup message and borked X session (see
attached photo of screen).

Similar bugs:

- https://bugs.freedesktop.org/show_bug.cgi?id=33165 (seems most similar)
- https://bugs.freedesktop.org/show_bug.cgi?id=69488
- https://bugs.freedesktop.org/show_bug.cgi?id=73373 (?, can startx)
- https://bugs.freedesktop.org/show_bug.cgi?id=69203 (?, no gpu lockup)
- https://bugs.freedesktop.org/show_bug.cgi?id=69465 (?, no gpu lockup)

Things tried:
--- firmware: I tried the nouveau-fw packages from Arch Linux's AUR, which
simply packages the firmware instructions here:
http://nouveau.freedesktop.org/wiki/VideoAcceleration/. I have diff'ed the
contents of /lib/firmware/nouveau/ and /tmp/nouveau/vuc-* + /tmp/nouveau/nv*,
and they are identical.
>From what I can tell, NVA3 (NV50 Tesla family) shouldn't need 3D Accel
firmware
(http://nouveau.freedesktop.org/wiki/InstallDRM/, 3D-accel firmware section):

"NV40 - NV50: No firmware needed. The Nouveau driver generates the ctxprogs
and
related state internally (commits 48c6dfb8 and 266229a5)."

With firmware in /lib/firmware/nouveau, I've tried with and without
`nouveau.config=NvGrUseFW=1`, though per the Kernel Parameters page
(http://nouveau.freedesktop.org/wiki/KernelModuleParameters/), this only seems
relevant for NVC0.

--- Per bug 69488, I tried with `nouveau.rumpm=0` and still get the lockup, not
to mention that report suggests this is fixed in 3.13, and I'm on 3.14

--- Comment #9 from jw.hendy at gmail.com ---
I just sent two traces to mmio [dot] dumps [at] gmail [dot] com, following the
instructions here:
- Setup: http://nouveau.freedesktop.org/wiki/MmioTrace/
- Running xinit/xinit + glxgears: https://wiki.ubuntu.com/X/MMIOTracing

Specific process:
- install nvidia drivers

$ sudo pacman -Q | grep nvidia
nvidia 334.21-4
nvidia-libgl 334.21-7
nvidia-utils 334.21-7

- boot system into recovery by adding `s` to kernel line

- unload nvidia and drm

# rmmod nvidia drm

- verify nvidia not loaded

# lsmod | grep nvidia   # no results returned

- start trace

(/sys/kernel/debug was already mounted)
# echo mmiotrace > /sys/kernel/debug/tracing/current_tracer
# cat /sys/kernel/debug/tracing/trace_pipe > /home/user/file.txt

- run test

1) ran `xinit "sleep 10"`
2) ran `xinit -e sh -c "glxgears & sleep 10"`

- stop trace

# echo nop > /sys/kernel/debug/tracing/current_tracer

- compressed files

$ xz -z file.txt
$ mv file.txt trace_quadro-fx-1800m_nv50-family-nva3_[xinit/glxgears].xz

- Send files and upload here as well (will come shortly)

This also prompted me to provide some more system details in case that is of
assistance:

- Computer: HP EliteBook 8540W (laptop)

- Running openbox 3.5.2 with following ~/.xinitrc contents:
#!/bin/sh
#
# ~/.xinitrc
#
# Executed by startx (run your window manager from here)

if [ -d /etc/X11/xinit/xinitrc.d ]; then
  for f in /etc/X11/xinit/xinitrc.d/*; do
    [ -x "$f" ] && . "$f"
  done
  unset f
fi

exec dbus-launch openbox-session

- various package information:

$ sudo pacman -Q | grep nouveau
nouveau-dri 10.1.0-4
xf86-video-nouveau 1.0.10-2

$ sudo pacman -Q |grep mesa
mesa 10.1.0-4
mesa-libgl 10.1.0-4

$ sudo pacman -Q | grep libtxc_dxtn
libtxc_dxtn 1.0.1-5

$ sudo pacmen -Q | grep xorg-server
xorg-server 1.15.0-5
xorg-server-common 1.15.0-5
xorg-server-utils 7.6-3

- screen information:

$ xrandr
Screen 0: minimum 320 x 200, current 1600 x 900, maximum 8192 x 8192
LVDS-1 connected 1600x900+0+0 (normal left inverted right x axis y axis) 344mm

   640x400       59.95  
   640x350       59.77  
DP-1 disconnected (normal left inverted right x axis y axis)
DP-2 disconnected (normal left inverted right x axis y axis)

It appears that all GDDR5 NVA3's hang on start. I've acquired such a
card,
hopefully I'll be able to make it work... we'll see.
