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.

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.

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.

Twenty years ago today Microsoft released Windows 3.11 while today Linus Torvalds released the Linux 3.11-rc5 kernel. He wished he could have released Linux 3.11 kernel final today, but that didn't happen.

The Common Display Framework (CDF) proposal for the Linux kernel that started last year is still being worked on. The CDF code is now up to its third revision, but this isn't likely to be the final revision before pushing it for mainline inclusion.

Separate from the important Radeon DPM support in Linux 3.11 that can sharply lower system power usage when using this forthcoming kernel update, there's been other power-related changes in recent Linux kernel releases.

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.

On Friday I reported that the Linux 3.11 kernel may lower power consumption for Intel systems. Since then, additional power consumption tests have revealed there are some changes within the Linux 3.11 but overall recent kernel releases are in better shape than the past.

It's still being investigated, but early indications are that the Linux 3.11 kernel is consuming less power at least for Intel CPUs.

Patches to support compressing SquashFS file-systems with the LZ4 compression algorithm have been proposed for the mainline Linux kernel, but it's not clear at the moment whether the work will be accepted.
