Aside from a new Intel PRIME'd driver this weekend, there's also new Intel DRM driver code available for testing.

Daniel Vetter updated the Intel DRM driver's -testing branch that will ultimately go into the Linux 3.7 kernel. The work that's available in this branch, which Intel is soliciting for its experimental Intel Linux enthusiasts to test out, includes:

- New modeset code framework.
- Tiny fix in the fb helper to go through the official dpms interface instead of calling the crtc helper code.
- forcewake code frobbery from Ben, code should be more in-line with what Windows does now.
- fixes for the render ring flush on hsw (Paulo)
- gpu frequency tracepoint
- vlv forcewake changes to better align it with our understanding of the forcewake magic.
- a few smaller cleanups

The most prominent is the new Intel mode-setting code that is quite significant. The continued work on Valley View and Haswell is also very pleasant for seeing that by the time this next-generation Intel hardware shipped it will be backed by quality open-source support.

Daniel mentioned these changes on the intel-gfx list.
