What’s New in Linux Kernel 3.12

  • The Radeon open-source kernel graphics driver has improved Dynamic Power Management, but it won’t be until Linux 3.13 where Radeon DPM is enabled by default along with HDMI audio.
  • A brand new DRM/KMS driver in the form of the Snapdragon MSM driver written by Rob Clark to go along with his reverse-engineered Freedreno driver for Qualcomm Snapdragon/Adreno graphics.
  • Run-time GPU power management so NVIDIA Optimus systems can dynamically power on/off the secondary GPU.
  • Experimental DRM render nodes support done by David Herrmann over the summer.
  • AMD Berlin APU support as the first APU built upon AMD’s Heterogeneous System Architecture (HSA).
  • The EXT4 file-system now supports aggressive extent caching and better recovery capabilities.
  • Random F2FS, XFS, and Btrfs file-system improvements. This kernel does deliver on disk improvements.
  • zRAM has been promoted out of the staging area of the kernel. ZRAM supports a compressed block device in RAM to avoid paging to disk and is mostly of benefit for systems with limited amounts of system memory.
  • Various staging driver updates and sound driver work and other glorious work
