I915 driver locks up

I915 driver locks up

[Stephen Clark]

Hi,

I am using 2.6.35.9-64.fc14.x86_64 running 1.3.9-1.fc14.x86_64
and am having my 945gma lock up in texture decompress according
to intel_gpu_top utility, when trying to play Myst 5.

Any fixes on the horizon?

Additional data point with 2.6.37-0.rc6.git0.1.fc15.x86_64 from rawhide 
I get:

and my X screen goes weird - have to switch to vty console.

Judging by your description, you've hit a bug in Mesa. Please verify the
bug with the current stable release (of Mesa) and file a bug report, and
be sure to include /sys/kernel/debug/dri/0/i915_error_state for the hang.

Thanks,

I had been using mesa-7.9.
I loaded mesa-7.10 similar results. There is no

/sys/kernel/debug/dri/0/i915_error_state

In fact there is nothing in the /sys/kernel/debug directory. Do I have 
to enable
something.

With the later kernel - things are worse X becomes totally useless it looks
like my lcd panel lost horizontal sync. With the 2.6.25 kernel X is 
still usable
this makes me think at least some of the problem is kernel related.

With 2.6.37-rc6 and mesa 7.10 with hardware acceleration turned off in wine-

You need to "mount -tdebugfs debug /sys/kernel/debug".

2.6.25 to present marks the transition between UMS and KMS, i.e. moving
of the userspace modesetting code into the kernel. And that should not
have regressed. Can you please, grab an intel_reg_dumper of the working
setup and the lost-sync setup, and include a drm.debug=0xe dmesg (i.e. add
drm.debug=0xe to your boot commandline)?

Good, those drivers are recent enough that I should be able to use the
error state to find the broken code.

Hi Chris,

I emailed the information you requested, it was quite large, and haven't 
seen it show up on
LKML yet. Don't know if it is being blocked by the ML or not.

Steve

Hi Chris,

Just wondering if you received what you needed from me. I still have the 
info
for the 2.6.37rc6 kernel that I haven't sent awaiting some kind of 
acknowledgment that
you received the initial info I send for the 2.6.35 kernel.

Hi Chris,

Just wanted to say I downloaded the latest drm_fixes from Dave Airlie 
and tried them
on 2.6.37rc7 and got the same gpu hang with the screen tearing 
horizontally. I have
the the intel gpu dump and a cat of the i915_error_state. Together they 
are over
2 megabytes. Should I send them to you directly since they seem to big 
for the mailing
list.

Regards,
Steve

Please do, or open a bug on bugs.freedesktop.org so that the error state
doesn't get lost. The intel_gpu_dump should be redundant, as the same
information, and more, is captured in the i915_error_state.
