3D on Intel SandyBridge?

Hi, all:

I've a FreeBSD 9.1 box running on Intel Sandy Bridge chips and have installed the latest Xorg and Intel driver from xorg-dev with KMS enabled (I also tried the new Xorg in our official ports but nothing different). It works fine for normal usage, however, every time I try to run some 3D applications, such as astro/stellarium, astro/google-earth and so on, my X hangs and keyboard is unresponsive (mouse is working though), so I've to reboot it manually.

I searched on our forum and found some guys say they can run 3D applications on FreeBSD with KMS flawlessly. So, is my box not able to run 3D applications? Need I do some tweaks? Thank you:)

P.S.:

1) When my X hangs, the sysctl hw.dri.0.info.i915_error_state shows:

2) What about my system:

Hello @YZMSQ,

I have an Intel Sandy Bridge card too. I installed games/tuxracer for testing 3D support. That's a simple 3D game that no need very resources in general. Well, It seems that games/tuxracer is a heavy game for me :e It's not playable on my laptop and it has very low fps. I'll test astro/google-earth astro/stellarium.
Thank you. Have you encountered "X freezing" problem when running those 3D applications? To be frank, even running a webgl demo in Chromium for several minutes can also lead my X to freeze. Very annoying.:\

For information purposes, see the PR ports/160422 related with google-earth issue.
Hi, thank you. Google Earth itself doesn't crash, it makes X to freeze after running several seconds. Some other 3D applications are also like this.:)
 
Well, I installed astro/stellarium. It's very slow (about 1.5 FPS) but it doesn't crash. Unfortunately, I can't test astro/google-earth since I'm on amd64. (astro/google-earth only works on i386)

Have you encountered "X freezing" problem when running those 3D applications?

No. 3D applications works for me and doesn't crash but they are very slow. The only problem I have is sometimes I encounter with some red strips on my screen.


it makes X to freeze after running several seconds. Some other 3D applications are also like this.

Please add this line in your /etc/X11/xorg.conf and post your /var/log/Xorg.0.log and /var/log/message the next time it happened:

Code:
Option "Log" "sync"

I'm not sure but it might help.

Thank you. I'll add this line to the /etc/X11/xorg.conf and post more information next time when it happens. And one more thing, could you share your /etc/X11/xorg.conf, uname -a command output and the version of your Xorg, libdrm, libGL, xf86-video-intel with us?:e
 
Of course :e

EDIT:
I've commented xorg.conf.

Code:
[CMD]# pkg_info -I -x xorg -x libdrm -x intel -x libGL[/CMD]
libGL-7.11.2_3      OpenGL library that renders using GLX or DRI
libGLU-7.11.2_2     OpenGL utility library
libdrm-2.4.31_1     Userspace interface to kernel Direct Rendering Module servi
xf86-video-intel-2.17.0_1 Driver for Intel integrated graphics chipsets
xorg-fonts-truetype-7.5.1 X.Org TrueType fonts
xorg-minimal-7.5.2  X.Org minimal distribution metaport
xorg-server-1.10.6_2,1 X.Org X server and related programs

I also have this lines in my /etc/make.conf:

Code:
[CMD]% cat /etc/make.conf[/CMD]

WITH_NEW_XORG=  yes
VIDEO_DRIVER=   intel

# unrelated stuff.

My machine is a GIGABYTE Q2532N.
Thank you very much for your sharing!:e
It seems that there is no Option "AIGLX" "True" enabled in xorg.conf, while I have it enabled in my box. So could you try it?:e
 
I've added that line:

Code:
[CMD]% grep AIG /var/log/Xorg.0.log[/CMD]
[    34.084] (**) Option "AIGLX" "True"
[    34.214] (**) AIGLX enabled
[    35.661] (EE) AIGLX error: dlopen of /usr/local/lib/dri/i965_dri.so failed (Cannot open "/usr/local/lib/dri/i965_dri.so")
[    35.661] (EE) AIGLX: reverting to software rendering
[    35.661] (II) AIGLX: Screen 0 is not DRI capable
[    35.975] (II) AIGLX: Loaded and initialized /usr/local/lib/dri/swrast_dri.so

There are some error messages. I'm not sure if it enabled correctly. Although, it doesn't have any effect. Low FPS without any crash. Can you explain what is that AIGLX please? Do you really need that line?

One thing I notice in your lines is "reverting to software rendering", I don't get that message in mine. Also can you verify that the i965_dri.so exists and has the appropriate permissions.

I can also confirm that the current Intel driver works with OpenGL(just not with the Linuxulator on AMD64, yet) because I just installed Cube2: Sauerbraten last night, I'm getting a solid 60 FPS.

Well, it's said that 3D performance will be improved with AIGLX enabled, not confirmed yet. Anyway, thank you very much for your help.:e Hopefully this issue will be fixed in the next release.

Do you use 9.1-RELEASE or -STABLE? Or 10.0-CURRENT?

IvyBridge, the next one up. But I'm pretty sure SandyBridge works too. ;)
Hi, thank you for your reply. And could you tell me the version of Xorg, libdrm, libGL, xf86-video-intel that you use?:)

Sure, these are my versions:

Xorg-7.5.2

libdrm-2.4.31_1

libGL-7.11.2_3

xf86-video-intel-2.17.0_1

Accelerated Indirect GLX (AIGLX) is an X server architecture designed to use 3D graphic rendering via OpenGL for acceleration of 2D functions, such as desktop and window management. AIGLX is very similar to Xgl except Xgl was developed by Novell, a private corporation, and AIGLX was developed in an open source environment. See also wiki AIGLX article.

@YZMSQ,

Check if VT-x is enabled in your BIOS. As recommended in this thread, disable "Virtualization" may help.

*EDIT*
Digging more I found this problem related: https://bugs.freedesktop.org/show_bug.cgi?id=47535.
Hi,
I disabled VT-X on BIOS just now and tried some 3D apps, for instance, astro/celestia-gtk, unfortunately, GPU crashed again. I saw these lines in my xorg.0.log:
Code:
[   486.342] [mi] EQ overflowing. The server is probably stuck in an infinite loop.
[   489.004] (EE) intel(0): Detected a hung GPU, disabling acceleration.
[   489.006] (EE) intel(0): When reporting this, please include i915_error_state from debugfs and the full dmesg.

Edit: My X didn't freeze, it just appeared rather slow due to the "disabling acceleration".

"EQ overflowing" means the X server's input event queue is overflowing. A good explanation of what it is, can be read here.

Please, attach your full Xorg.0.log.

P.S. Remove anything related to eventual VESA entries in xorg.conf.
