\"Linux<\/a><\/p>\n

Linus Torvalds finally announced Linux Kernel 3.12<\/b>. Here’re the new features and how to install \/ upgrade to Kernel 3.12<\/b> in Ubuntu 13.10, Ubuntu 12.04, Ubuntu 12.10<\/b> and Linux Mint<\/b>.<\/p>\n

Linus Torvalds wrote on the mailing list (read the announcement<\/a>):<\/p>\n

I was vacillating whether to do an rc8 or just cut the final 3.12, but
\nsince the biggest reason to *not* do a final release was not so much
\nthe state of the code, as simply the fact that I’ll be traveling with
\nvery bad internet connection next week, I didn’t really want to delay
\nthe release. Sure, we had a number of driver reverts, and there was an
\nannoying auto-NUMA memory corruption fix series, but none of it was
\nreally worth delaying 3.12 for.<\/p>\n

But the fact that I’m going to be (effectively) off-line next week
\nmeans that I’m *not* opening the merge window for 3.13 yet …<\/p>\n

What’s New in Linux Kernel 3.12:<\/h3>\n
  • 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. <\/li>\n
  • 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.<\/li>\n
  • Run-time GPU power management so NVIDIA Optimus systems can dynamically power on\/off the secondary GPU. <\/li>\n
  • Experimental DRM render nodes support done by David Herrmann over the summer.<\/li>\n
  • AMD Berlin APU support as the first APU built upon AMD’s Heterogeneous System Architecture (HSA).<\/li>\n
  • The EXT4 file-system now supports aggressive extent caching and better recovery capabilities.<\/li>\n
  • Random F2FS, XFS, and Btrfs file-system improvements. This kernel does deliver on disk improvements.<\/li>\n
  • 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.<\/li>\n
  • Various staging driver updates and sound driver work and other glorious work.<\/li>\n
