Intel Already Has Graphics Code For Testing For Linux 3.21/Linux 4.1

While we're only in the middle of the Linux 3.20 kernel, for what might still be called Linux 4.0, Intel already has updated DRM driver code for testing that will not be merged until Linux 3.21 (or what might also be known as Linux 4.1).

Daniel Vetter announced the updated drm-intel-testing branch on Friday with code that's under testing for Linux 3.21. Among the changes with this initial post-3.20/4.0 Intel DRM set of changes are greater use of atomic helpers / continued migration on atomic mode-setting, refactoring of the initial plane config code, PPGTT prep pages for dynamic page-table allocation, frame-buffer modifier support, many Skylake workaround patches, vGPU support for XenGT on the client side, and many smaller changes.

The continued work on Linux enablement for Intel Skylake is great with the Skylake Core M chips coming in a few months. Seeing more of XenGT get into shape is also exciting.
