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.
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.
While the Linux 3.12 kernel isn't even up to its first RC release and thus the merge window hasn't closed yet, Linux 3.12 has already collected a number of promising features for the open-source kernel.
For those monitoring the daily advancements to the open-source DRM (Direct Rendering Manager) kernel graphics driver, the big feature pull request has been sent in for the Linux 3.12 kernel merge window.
The Linux 3.12 kernel will feature improvements to existing sound drivers and there's also some new drivers / audio hardware support.
The Linux 3.12 kernel will feature improvements to ACPI and power management in general thanks to recent developments.
While it didn't make it as part of the initial staging pull for the Linux 3.12 merge window, on Sunday dm-writeboost was proposed for staging. DM-Writeboost is new log-structured Linux caching software.
One day after the Linux 3.11 kernel release, Greg Kroah-Hartman already sent in his usual batch of pull requests for the Linux 3.12 kernel.
Greg Kroah-Hartman has noted that the Linux Foundation has joined the UEFI.org group. With his new UEFI dealings, he's decided to better document the steps needed to build and boot a self-signed Linux kernel that will work on UEFI SecureBoot enabled systems.
For those not paying attention, Linus Torvalds has done a Labor Day release of the Linux 3.11 kernel.
The SimpleDRM driver has been revised ahead of the Linux 3.12 kernel merge window. This simple DRM/KMS driver that's generic has been around for a few months now and David Herrmann is hoping it will be reviewed and ready in time.
For those curious about the DRM render/mode-set nodes work that was successfully accomplished via GSoC by David Herrmann, he has written another blog post at length about his accomplishments.
While the Linux 3.11 kernel hasn't even been released yet (hopefully this weekend) and with it will come many exciting changes, there's already a lot to get excited for with the Linux 3.12 kernel.
The Linux 3.11 kernel will hopefully be released this weekend so if you've fallen behind on your Phoronix reading or have got lost in the dozens of different 3.11/3.12/not-merged articles about new Linux kernel features, here's a recap of some of the most prominent features that are introduced in the Linux 3.11 kernel.
In large part because of Canonical's new focus around Ubuntu Touch on phone/tablet devices, the Ubuntu developers are wanting a new revocable memory API for the Linux kernel to help in low-memory scenarios.
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.
The upcoming Linux 3.12 kernel will feature a DRM/KMS driver that supports Qualcomm Snapdragon/Adreno graphics.
It was on this day twenty-two years ago that Linus Torvalds made the first public release of his Linux operating system. In celebrating the 22nd birthday, the Linux 3.11-rc7 kernel has been tagged.
David Herrmann, the student developer working on DRM Render Nodes this summer and has been a longtime proponent of killing the Linux kernel console, has written at length about VT (virtual terminal) switching on Linux systems.
David Herrmann continues his GSoC summer project of implementing DRM Render Nodes support and as part of that VMA Access Management for the Linux kernel.
With the Linux 3.11 kernel due to be released in the coming weeks, here's an overview of the most exciting changes for this next major Linux kernel update.
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.
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.
