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."
In addition to the already exciting features of the Linux 3.9 kernel, this next release will also bring several new features to the Btrfs file-system.
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 EXT4 file-system in the forthcoming Linux 3.9 kernel will support using the previously-introduced punch hole functionality for inodes not using extent maps.
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.
Samsung developers have worked up a set of improvements to the new F2FS file-system for the Linux kernel. The F2FS work in Linux 3.9 mostly comes down to fixing issues with the Flash-Friendly File-System and implementing some new functionality.
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.
The XFS file-system update for the Linux 3.9 kernel isn't particularly exciting, but it does address some open bugs and regressions for this still very relevant and competitive Linux file-system.
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.
A Google engineer working on Linux, Kent Overstreet, has reworked the Linux DIO (Direct I/O) code so that it's "vastly simpler" while also being faster for at least some test cases.
The NVIDIA Tegra DRM driver has received a set of patches today that provide various enhancements to this open-source ARM SoC graphics driver.
Rafael Wysocki has offered a glimpse at what's to be merged into mainline in the coming weeks for the Linux 3.9 kernel when it comes to ACPI and power management.
The Linux kernel RNG implementation for providing random numbers has worked quite well for its years in use. However, a new jitter entropy generator implementation has been proposed that is capable of providing 100 kB/s throughput of randomness.
A week has passed since the previous release candidate so Linus Torvalds has now tagged the Linux 3.8-rc7 kernel. This latest kernel release still isn't as quiet on development activity as he'd like, but it's getting better.
Greg Kroah-Hartman has confirmed he is working on an implementation of D-Bus for merging into the mainline Linux kernel.
While the Linux 3.8 kernel hasn't even been released yet, several of the noteworthy features slated to be merged for the Linux 3.9 kernel are already known.
