            Bug ID: 66281
           Summary: DRI_PRIME=1 glxinfo crashes and causes session to
                    restart
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.13 rc2
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: mortem.dei@gmail.com
        Regression: No

I have a new laptop but the secondary GPU can't be accessed by the system
(neither with Nouveau nor bumblebee). With the kernel 3.12 the output of xrandr
didn't even show the card, but with the new one I do get the following output:


xrandr --listproviders

Providers: number : 2
Provider 0: id: 0x66 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs:
4 outputs: 3 associated providers: 1 name:Intel
Provider 1: id: 0x3f cap: 0x5, Source Output, Source Offload crtcs: 0 outputs:
0 associated providers: 1 name:nouveau

However, when I try to run anything with DRI_PRIME=1 glxinfo the system crashes
and I have to restart the session.

Exactly same thing is happening with me. I have the following kernel:

uname -a output:

0 associated providers: 1 name:nouveau

However, when I try to run anything with DRI_PRIME=1 glxinfo the system crashes
and I have to restart the session.

I am also neither able to load NVIDIA drivers, nor run bumblebee.

Make sure that

(a) You're using a kernel 3.14 or higher (3.13 introduced modesetting but not
the firmware required for acceleration for the gk208)
(b) You're not using bumblebee (3.12 introduced runtime pm support for nouveau)
(c) You have runtime pm and vga switcheroo enabled in your kernel
(d) You're using xf86-video-nouveau 1.0.10 (first version to add gk208 support)

If you want 3d accel to be anywhere near working, I would also recommend
grabbing mesa 10.2-rc1 as that has a number of instruction emission fixes,
although simple programs like glxgears are likely to work on older mesa
versions as well.

Lastly, as per http://nouveau.freedesktop.org/wiki/Bugs/, you will find the fdo
bugtracker a much more reliable way to reach nouveau developers.

Thank you for your response! 

(a) I am using the following kernel (3.14.2)

uname -a output:

Linux localhost.localdomain 3.14.2-200.fc20.x86_64 #1 SMP Mon Apr 28 14:40:57
UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

(b) Although I had installed bumblebee, it is not running. Optirun said that
bumblebee service is not running. I have removed bumblebee now.

(c) How do I check that runtime pm and vga switcheroo are enabled in my kernel.
(Sorry, but I am a newbie to Linux).

(d) I cannot be sure about this as well. AFAIK, the nouveau module is built
into the kernel. The modinfo result is as below:

Actually I am working on some OpenGL/GLSL projects, for which I need GLSL 4.3,
which I believe is still not available in nouveau driver. I was looking forward
to be able to install the latest NVIDIA drivers. Will mesa 10,2-rcl solve this
issue? Can you please recommend any other solution.

Thank you for your time and effort. For future reference, I will use wiki/bugs.

If you have your .config (which, depending on options, may be visible from
/proc/config.gz), you can look for

CONFIG_VGA_SWITCHEROO
CONFIG_PM_RUNTIME

Make sure both of those are set to 'y'. (This is only for optimus-type systems,
of which I'm assuming yours is one.)

xf86-video-nouveau is the xorg ddx which interacts with the kernel driver. In
some distros, for maximal confusion, it is called something else, like
xorg-xserver-video-nouveau or something like that (don't have the exact name,
sorry).

Mesa 10.2 will support a few more extensions which are part of GL4+, but will
not provide all the features required to advertise GL 4.0 support (or GL 4.3,
obviously). You can see the general progress of things at
http://cgit.freedesktop.org/mesa/mesa/tree/docs/GL3.txt.

However it's rare to need ALL of the features available in GL 4.3, so chances
are you could restrict yourself to a lower, supported version + a few
extensions.

Also note that GK208, while covered by the nvc0 driver, has some extra-special
issues that the GK10x cards (and GF1xx cards) don't have. Hopefully they'll be
resolved semi-soon, but the hardware is not easily available.

There is no config.gz file in my system. I have tried using "locate" as well.
Is there some other way I can find this out.

Can you please tell me how to find out (or search) if this is the case. Even if
you can tell me where and how to look for, I will follow.

The latest mesa based DRI drivers through yum is listed as 10.1.1. Will it
work?

http://nouveau.freedesktop.org/wiki/Optimus/

Check

/sys/kernel/debug/vgaswitcheroo/switch
/sys/class/drm/card1/power/runtime_status

If both files are there, that means that you have both of those options.
Further you can check dmesg for references to 'optimus'.

A quick way to find out the version of xf86-video-nouveau is to look in your
Xorg.0.log file (often located in /var/log). There should be a section like

[     7.016] (II) Loading /usr/lib64/xorg/modules/drivers/nouveau_drv.so
[     7.019] (II) Module nouveau: vendor="X.Org Foundation"
[     7.019]    compiled for 1.15.0, module version = 1.0.10
[     7.019]    Module class: X.Org Video Driver
[     7.019]    ABI class: X.Org Video Driver, version 15.0

Note the "module version". Make sure yours is 1.0.10. Earlier versions did not
support GK208.

A large number of shader opcode generation issues for GK110/GK208 are fixed in
the 10.2 release. 10.1.x will work enough for like glxgears though. The final
10.2 release should be out on May 30 or so, dunno how long it takes to get into
distros though.

I guess I have the same problem on a T420, see
"https://bugs.freedesktop.org/show_bug.cgi?id=80769".

Can you boot your system with setting the display to discrete (instead of
Optimus) in the BIOS? https://bugzilla.kernel.org/show_bug.cgi?id=80321
