It appears that the out-of-tree BFS scheduler lost some of its charm with the Linux 3.11 kernel release where CFS is now running faster.
The Linux 3.12 kernel was released on Sunday evening but prior to that was a last-minute pull request that got rejected by Linus Torvalds and with it he reaffirmed the focus of Linux on 64-bit.
As was anticipated, the Linux 3.12 kernel was released this afternoon. The Linux 3.12 kernel is a mighty big update but beyond announcing its debut, Linus Torvalds also made mention of a delay in the Linux 3.13 merge window and has begun expressing possible plans for a Linux 4.0 release in about one year's time.
With the Linux 3.12 kernel likely being officially released this evening if there are no last-minute delays, here is a look again at some of the top features and changes for this major open-source Linux upgrade.
The release of the Linux 3.12 kernel is imminent so here's a recap of some of the benchmarks we have carried out so far on this exciting kernel upgrade.
KTAP is a lightweight script-based dynamic tracing tool for Linux that remains independent of GCC and doesn't require kernel module re-compilation. KTAP 0.3 was just announced this morning and with it comes some more features.
The seventh -- and likely last -- release candidate for the Linux 3.12 kernel is now available. While late in the release cycle, there's been an uptick in new patches merged this week.
While the Linux 3.12 kernel hasn't even been released yet, going back to late August Intel has been plotting their graphics improvements for Linux 3.13. In September Intel was already sending in drm-next changes and they have done more rounds since. Another drm-next pull request was issued today for the Intel DRM driver.
The Linux 3.12 kernel brings faster open-source AMD graphics due to a CPUfreq subsystem change but there also appears to be faster disk performance.
Rob Clark has queued up some interesting changes to his "MSM" DRM driver for reverse-engineered open-source Qualcomm Snapdragon display support. The changes queued up for the Linux 3.13 kernel will include PRIME and render nodes capabilities.
The Armada DRM display driver for Marvell "Dove" devices is being queued up for hopeful inclusion into the Linux 3.13 kernel.
Linus Torvalds released the Linux 3.12-rc6 kernel a day early due to flying out tonight for the Linux Kernel Summit happening next week in Edinburgh. Overall, things are quieting down for the Linux 3.12 kernel with the end being near.
NFTables is a new firewall subsystem / packet filtering engine for the Linux kernel that is poised to replace iptables. NFTables has been in development for several years by the upstream author of Netfilter. This new nftables system is set to be merged now into the Linux 3.13 kernel.
Going back years there's been work to build the Linux kernel with LLVM's Clang compiler rather than GCC. It's taken a lot of work by many individuals and organizations, but it's becoming an easier task to accomplish for multiple architectures. Here's where the Clang'ed Linux kernel is at today.
Kernel developers are still working on CPU Boost mode support for the Linux kernel's cpufreq to unify hardware and software-based solutions for CPU overclocking.
Continuing in Linus Torvalds' usual Sunday tradition, the next release candidate of the Linux kernel is now available. With today's 3.12-rc5 kernel release, the rate of change for the Linux 3.12 kernel is lessening.
Greg Kroah-Hartman announced the release of Linux 3.0.100 on Sunday and with that he intends to end-of-life this long-term kernel series in the coming days.
For months now there's been an Armada DRM/KMS graphics driver for Marvell Armada ARM SoCs. Having gone through several patch revisions, it appears that all major issues have now been addressed for this nearly 5,000 line open-source driver.
As usual, Linus Torvalds released the latest Linux development kernel on Sunday.
The third release candidate for the Linux 3.12 kernel is now available.
There's still ongoing work to mainline the open-source exFAT file-system support within the Linux kernel.
In the past number of months on Phoronix there have been numerous articles about the conquest of David Herrmann and others to killing CONFIG_VT in the Linux kernel or at least deprecating it. Here's the latest material on the matter.
Linus Torvalds has announced the release of Linux 3.12-rc2, but it's not overly exciting.
From interesting events to a number of important announcements, next week should be very exciting for open-source fans, gamers, and Linux enthusiasts.
For unifying common FGPA drivers, a FPGA subsystem has been proposed for the Linux kernel.
When running some Iris Pro 5200 graphics benchmarks we were surprised to see the Intel Linux 3.12 kernel changes didn't boost the performance at all given that it enables the 128MB of dedicated video memory. Additionally, within the forums there's been reports of Intel users seeing decreased performance out of the 3.12 kernel code. To clear up matters a bit, here's some Intel Ivy Bridge tests on Linux 3.12 compared to prior kernel releases.
While at the first day of LinuxCon in New Orlenans, Linus Torvalds went ahead and released the Linux 3.12-rc1 kernel as the first major development release for this major forthcoming open-source kernel update.
The merge window for the Linux 3.12 kernel is coming to an end and 3.12-rc1 should be released soon. Here's an overview of the interesting merges that happened over the past two weeks as new features for Linux 3.12.
We're late into the Linux 3.12 merge window and other prominent file-systems were already updated but on Thursday evening the Btrfs updates for the 3.12 kernel were finally published. With the new Btrfs pull does come some notable changes for this next-generation Linux file-system.
After the Linux 3.11 kernel was codenamed "Linux for Workgroups" in reminisce of Microsoft Windows for Workgroups 3.11, Linus Torvalds is using "Suicidal Squirrel" as the Linux 3.12 kernel codename.
