** Description changed:
- The Mesa project requires a kernel change to support OpenGL 3.0
- on Intel's gen7 (Ivy Bridge) hardware.
+ [Impact]
+ The Mesa project requires a kernel change to support OpenGL 3.0 on Intel's
gen7 (Ivy Bridge) hardware. Without this, applications requiring GL 3.0 won't
work properly for owners of this hardware.
+ [Test Case]
To reproduce the issue, run:
$ glxinfo| grep "OpenGL version"
This result is the failing case:
OpenGL version string: 2.1 Mesa 8.0.2
This result is the successful case:
OpenGL version string: 3.0 Mesa 8.0.2
+ [Fix]
To resolve the issue, the kernel commit
ae662d31264979e52581bd2573bf0b82812f52ab
"drm/i915: Add support for resetting the SO write pointers on gen7."
should be cherry-picked.
(This commit is available in the kernel mainline.)
I have tested this with
git://kernel.ubuntu.com/ubuntu/ubuntu-precise.git
The commit cherry picks cleanly, and resolves the issue.
