The Linux 3.11-rc2 kernel isn't even out yet, but Intel's open-source developers have already begun lining up DRM kernel graphics driver changes for the Linux 3.12 kernel.

The first (of several) Intel DRM pull requests for targeting the Linux 3.12 kernel was submitted on Thursday. There isn't much in the way of interesting end-user work, but the changes, per Daniel Vetter's message include

- Follow-up refactoring after the shared dpll rework that landed in 3.11.
- Oddball prep cleanups from Ben for ppgtt.
- Encoder->get_config state tracking infrastructure.
- Used by the experimental fastboot support from Jesse (disabled by default).
- Make the error state file official and add it to our sysfs interface.
- Drm_mm prep changes from Ben, prepares to embedd the drm_mm_node (which will be used by the vma rework later on).
- Interrupt handling rework, follow up cleanups to the VECS enabling, hpd storm handling and fifo underrun reporting.
- Big pile of smaller cleanups, code improvements and related stuff.
