1. This is the first time GEM can go so far on our 855gm.
2. This doesn't happen on 9xx.

commit 8ec6e036792decf5149a209e51cb5e93ccc5c754
Author: Eric Anholt <eric@anholt.net>
Date:   Tue May 26 20:45:29 2009 -0700

    i915: Fall back on NPOT textured metaops on 830-class.

(now readpix just shows off that software fallbacks on 8xx are incorrect).
Comment 9 liuhaien 2009-06-03 19:51:47 UTC
