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.
Using the latest ZFS On Linux support, the ZFS file-system was benchmarked from the Linux 3.10 stable kernel and compared to the Linux file-system competition.
A power capping framework has been proposed for the mainline Linux kernel to provide some standard interfaces for the increasing amount of drivers/hardware that support power monitoring and limiting.
Cross-device synchronization support for DMA-BUF is still being worked on for a future Linux kernel release.
The third release candidate is out for the Linux 3.11 kernel and it incorporates many more patches -- too many more than Linus Torvalds would prefer at this time.
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.
Samsung Electronics has dramatically ramped up their Linux hiring and development efforts in the past three years and they are still on track for hiring another 20,000 Linux and open-source developers.
Rob Clark has posted the second version of his MSM DRM driver, an open-source reverse-engineered kernel Direct Rendering Manager driver for Qualcomm's "Snapdragon" SoCs.
Linus Torvalds on Sunday announced the second release candidate for the Linux 3.11 kernel.
Linus Torvalds is usually complaining about too many pull requests during the Linux kernel development cycle when past its merge window, but this time around he's complaining about too few patches this week. He's also proclaimed himself the Goldilocks of kernel development.
Linus Torvalds announced the Linux 3.11-rc1 release on Sunday afternoon.
Nearing the end of the Linux 3.11 kernel with most (if not all) of the interesting pull requests merged, here's a look at the exciting features that will premiere in this next Linux kernel release.
The Linux 3.11 kernel will support kernel images compressed using the LZ4 compression algorithm.
A Linux kernel scheduler that's power-aware and aims for offering power-efficient performance has been published. The developer behind this new Linux scheduler is presently seeking other developer feedback on his set of nine patches.
Besides the Btrfs file-system updates that were merged today for the Linux 3.11 kernel, the XFS changes were also submitted and pulled.
The Hypertext Transfer Protocol Bis Working Group of the IETF has published a new Internet draft of the HTTP 2.0 protocol.
David Airlie has submitted the DRM subsystem pull request for the Linux 3.11 kernel that is of monster size. The Radeon DRM kernel driver is now perhaps the single biggest Linux kernel driver by code size after the merging of its huge dynamic power management code addition.
Linux wireless developers remain at work on support for 5 and 10MHz channels in order to prepare for future 802.11 standards.
Beyond Xen and KVM virtualization coming to 64-bit ARM in the Linux 3.11, there's also other ARM architecture and SoC advancements within this next major kernel release.
Samsung's Flash-Friendly File-System (F2FS) has been updated for the Linux 3.11 merge window.
The sound/audio kernel driver pull request has been submitted for the Linux 3.11 merge window. The changes this time around aren't too exciting, but there's the continued bettering of the Linux audio stack.
Ted Ts'o has already sent in his pull request for EXT4 file-system changes targeting the Linux 3.11 kernel.
The staging pull has been submitted for the Linux 3.11 kernel merge window and with it comes client support for Lustre, the high-performance parallel distributed file-system.
The Linux 3.11 kernel that's officially just been under development since last night's 3.10 release will feature support for KVM and Xen virtualization on 64-bit ARM (AArch64) hardware.
The Linux 3.10 kernel, which yields the biggest changes in years, has been officially released this Sunday evening.
The Linux support for Apple's new Haswell-based MacBook Air is less than desirable, but at least it's on the path to getting better.
The in-kernel DRM graphics driver changes lined up for the Linux 3.11 kernel are possibly the biggest set of Direct Rendering Manager changes ever, but it looks unlikely that the VIA KMS driver will be merged for this release.
