Intel Already Begins Thinking About Linux 3.13 Kernel

The Linux 3.11 kernel hasn't even been released yet, at which point the Linux 3.12 kernel merge window will then open, but Intel's Open-Source Technology Center is already busy at work on features not likely to land until Linux 3.13.

Daniel Vetter of Intel OTC published a new drm-intel-testing Git branch state on Friday that provides PC8+ support, VMA patches, optimized CPU cache flushing, RC6 tuning, and much more (embedded below is a full list).

Daniel also noted in his mailing list post, "a second heads-up: I expect that the next feature round won't hit 3.12, so from now on it's all for 3.13. Or at least very likely for 3.13."

- PC8+ support
- More vma patches
- Kconfig option to enable preliminary support by default
- Optimized cpu cache flush handling and support for write-through caching of display planes on Iris
- RC6 tuning from Stéphane Marchesin for more stability
- VECS seqno wrap/semaphores fix (Ben)
- A pile of smaller cleanups and improvements all over
