Subject: Sandy Bridge GPU hang reproducer...
Date: Wed, 18 May 2011 12:38:44 +0100	[thread overview]
Message-ID: <BANLkTimKiP0W0A3pQRS7iA-wVibYU+aEtw@mail.gmail.com> (raw)

Hi Chris et al,

On my Sandy Bridge GPU (8086:0126 rev 09) laptop, I often see hangs
that are correctly recovered and sometimes ones which aren't (causing
X lockup or kernel hard lock), hurting usability.

I'm able to reproduce GPU hangs often with the composite tests in
rendercheck (may need to restart a few times):

$ ./rendercheck -t composite,cacomposite
Begin composite mask test on a8
<command hang, maybe GPU hang too>

I'm on the internal LVDS panel (1600x900), and can produce this with
2.6.39-rc7 and Xorg 1.10.1 (Ubuntu 11.04 + gnome 3). Kernel logs are
captured booting with 'drm.debug=0x04' [1], and i915 error state is at
http://quora.org/2011/i915_error_state.txt.bz2 .

Any joy in reproducing it there?

Thanks,
  Daniel
