One of the areas of hardware power management that can yield a surprising amount of power-savings but is often overlooked comes down to the system memory. Fortunately, new Linux kernel patches continue to be written for improving the Linux kernel RAM power management.
Red Hat's Mikulas Patocka has posted a set of Linux kernel patches that parallelize the dm-crypt sub-system.
Samsung developers last week provided patches for a new cpufreq governor dubbed "LAB", or the "Legacy Application Boost", for the Linux kernel.
The Linux 3.9-rc6 kernel was released over the night. With Linus expecting next week's 3.9-rc7 kernel to be the last test release, the final release of the Linux 3.9 kernel is expected in about two weeks time.
The Linux kernel has been ported to the Texas Instruments TI-Nspire. The TI-Nspire series platform powers higher-end graphing calculators in recent years from the Dallas-based company.
Linus Torvalds released Linux 3.9-rc5 on Easter. This kernel midway through the Linux 3.9 kernel cycle isn't particularly thrilling but does provide fixes for new features.
Linus Torvalds announced the release of the RC4 for the Linux 3.9 kernel on Saturday evening, but its development still has not slowed down.
Is the Tux3 file-system alive and well for Linux or will it face a fate like Reiser4 where it may never see a mainline state?
Linus Torvalds put out the Linux 3.9-rc3 kernel on Sunday afternoon.
Introduced to the world on Monday and already revised today is the Linux Kernel Wait-Free Concurrent Queue Implementation.
The Overlay File-System has been in development for several years and is used by some notable Linux distributions, but has yet to be merged into the mainline Linux kernel after having to be pulled a few times in the past. The new plan is to merge OverlayFS for the Linux 3.10 kernel.
The second release candidate to the Linux 3.9 kernel is now available. Standing out in this week's kernel development update is work on WiFi drivers and other updates throughout kernel-land.
While there are many interesting features to the Linux 3.9 kernel, there is some functionality you will not find yet within the mainline Linux kernel.
Progress is being made within the Linux kernel for reducing the I/O wait times and system interactivity/responsiveness when dealing with large I/O operations.
Linus Torvalds released the first release candidate for the Linux 3.9 kernel on Sunday afternoon. He says with this kernel there's changes all over the place, but the merge window was a bit rocky but fortunately with all of the nasty bugs "each time people were on them like paparazzi on Justin Bieber."
Aside from Google Zopfli there is some more Linux/open-source compression algorithm news today. The LZO compression/decompression support within the Linux kernel has been updated against upstream. LZO in Linux 3.9 will now be much faster.
The merge window for the Linux 3.9 kernel is coming to a close and most of the major merges have already occurred, so let's take a look at some of the best new features coming to this next Linux kernel release.
The DRM pull request for the new features to be introduced in the Linux 3.9 kernel have been presented.
A Linux kernel exploit was made public this weekend that affects versions of Linux going back to the 3.3 kernel. This exploit allows for user-space programs to gain root access through a bug in the kernel's networking code.
The PCI pull request for the Linux 3.9 kernel reveals that more hot-plugging work is about to land plus developers are still working on the handling of PCI Express ASPM (Active State Power Management), the cause of the major Linux kernel power regression of 2011.
With the ATA pull for the Linux 3.9 kernel finally comes ZPODD, the Zero-Power Optical Device Driver.
As usual, there's lots of changes within the staging area that's been queued up for the Linux 3.9 kernel.
The feature pull for ACPI and power management updates to be introduced in the Linux 3.9 kernel were merged.
The input pull request for the Linux 3.9 kernel has went in and it supports new touchpad drivers and more.
NDISwrapper, the open-source project that implements the Microsoft Windows kernel API and NDIS API within Linux for running Windows wireless network card drivers on Linux, has been updated. This effectively native Windows WiFi network driver project for Linux now runs on new kernels, up to and including the brand new Linux 3.8 kernel. This is the first release from the project in more than one year.
Ingo Molnar has already submitted his x86 platform pull request for the Linux 3.9 kernel that's now officially under development since last night. With the Linux 3.9 kernel will come support for Google's Android "Goldfish" emulator.
The Linux 3.8 kernel was released on Monday afternoon by Linus Torvalds. This is a very exciting kernel update.
A System Frame-buffer Bus has been proposed for the Linux kernel. The focus of this new bus is to address the problem of many different graphics drivers, e.g. DRM and FBDEV, attempting to access the graphics card's frame-buffer and no clean way for addressing control of it.
The Texas Instruments' OMAP DRM pull request for the Linux 3.9 kernel is now known. The OMAP DRM graphics driver will leave the kernel's staging area while at the same time picking up support for the OMAP5 SoC.
The ALSA SoC (ASoC) layer will see a number of new improvements and also a new sound driver within the Linux 3.9 kernel.
