Update i915 GPU driver to Linux 3.8
Our kernel-side i915 GPU driver is getting old: platforms starting with Haswell are not supported at all. Furthermore, it lacks at least one feature required by Mesa 9.2+.
Current status (2013-10-24)
An i915 update is in progress by kib@ under sponsorship of the FreeBSD Foundation.
It needs that the update to the DRM generic code makes progress.
- Mesa 9.2 requires a feature (hardware context) we don't have. OpenBSD has this feature.
libdrm 2.4.48 and Mesa 10.0 may use a newer ioctl.
