GPU Runtime Power Management Coming For Linux 3.12

The latest DRM subsystem work to be merged for the upcoming Linux 3.12 kernel is runtime power management support to be able to dynamically turn on/off secondary GPUs. This is an especially important feature for those with dual GPU (e.g. Optimus) laptops where the secondary GPU doesn't need to be constantly running.

Linux 3.11-rc7 Planned To Celebrate 22 Years Of Linux

Linus Torvalds released the Linux 3.11-rc6 kernel on Sunday evening. This sixth release candidate is fairly quiet for the Linux 3.11 kernel, but Linus is already planning to time the 3.11-rc7 release to celebrate the 22nd birthday of Linux.

ZRAM Might Finally Be Moved Out Of Linux Staging

The zRAM Linux kernel module that aims to increase Linux's performance by avoiding paging to disk and optimizing to use a compressed block device in RAM, may finally leave the Linux kernel staging area and be promoted to main. This code that mostly benefits users with limited amounts of system RAM has become quite mature and is becoming widely adopted, which in part is why it's trying to be promoted out of the staging area.

Linux 3.11-rc4 Kernel Brings More Changes

It's time for another Sunday release of the Linux kernel. While it's out on schedule, the Linux 3.11-rc4 release carries about the same amount of changes as 3.11-rc3, which isn't making Linus Torvalds happy.
