While we're still waiting on 3D/OpenGL guest acceleration for KVM/QEMU guests, a Bochs DRM kernel driver is still being developed for the virtual VGA adapters using the Bochs DISPI interface on QEMU.
A "Knock" patch has been proposed for the mainline Linux kernel that would provide NAT-compatible, TCP stealthy port knocking for improved network security of Linux systems.
KTAP version 0.4 is now available as the script-based dynamic tracing tool for Linux.
While Fedora 20 isn't going to be released until at least the middle of the month and the Linux 3.12 kernel has been stable since the start of November, the bleeding-edge Fedora Linux will not be shipping with Linux 3.12 by default.
Linus Torvalds has done another Friday release of the latest Linux 3.13 kernel merge window.
The BFS Linux kernel scheduler by Con Kolivas is up to version 0.444 this week and this updated scheduler is available for the Linux 3.12 kernel.
Matthew Garrett has written an insightful blog post about security issues pertaining to the Linux kernel's kexec functionality that could defeat any security benefits provided by Secure Boot. Using kexec could even allow you to boot a Windows kernel.
While the Intel, Radeon, and Nouveau (NVIDIA) DRM drivers are the most commonly talked about kernel graphics drivers talked about on Phoronix for the Direct Rendering Manager, there have been many smaller DRM/KMS drivers seeing the light of day in recent kernels.
At the request of many Phoronix readers, here are some new battery power usage benchmarks on every recent Linux kernel release from Linux 3.7.0 to Linux 3.13 Git. Has an Intel "Ivy Bridge" Ultrabook's power consumption changed much due to the continuous kernel churn? Here's the answer.
Linus Torvalds is celebrating Black Friday by giving out a great deal for Linux users: the Linux 3.13-rc2 kernel is now available for testing and regression spotting.
While zRAM has been part of the Linux kernel's staging area for a while now and this RAM-based compressed block device is used by Chrome OS and Android, it's struggling to get promoted to the main area of the kernel.
Linus Torvalds announced the Linux 3.13-rc1 kernel on Friday.
For those keeping track of Linux 3.13 kernel activity, another DRM subsystem pull update was submitted during this merge window.
Today at the virtual Ubuntu Developer Summit it was generally agreed upon that Ubuntu 14.04 LTS will be targeting the Linux 3.13 kernel to power the distribution, but there's a chance 3.14 might happen.
A second pull request has been submitted for the Linux 3.13 kernel that provides further updates to the often less than desirable ACPI and power management code.
SquashFS is commonly used by Linux distributions as a compressed read-only file-system commonly used by the Live CD/DVD/USB versions of distributions like Ubuntu, Arch, Fedora, Debian, etc. There's some performance improvements to be merged into the Linux kernel that will make SquashFS even faster. SquashFS decompression can be multiple times faster with these patches.
While there's many exciting features to Linux 3.13, there's still some features that you won't find in this next major Linux kernel update.
The /dev/random changes went in for the Linux 3.13 kernel and this pull request was even interesting for the very promising next kernel release. While not in Linux 3.13, it's mentioned the Linux kernel might also end up taking a security feature from the FreeBSD playbook.
While the merge window for the Linux 3.13 kernel isn't even over yet, this next major kernel update is already looking to be rather exciting with a number of new features.
While many independent Phoronix articles have been covering the Linux 3.13 kernel changes for the individual DRM graphics drivers, the DRM subsystem pull request in its entirety was submitted yesterday for mainlining.
The Kernel-based Virtual Machine updates for the Linux 3.13 kernel were filed today and includes a fair amount of improvements for virtualization on PowerPC hardware, but there's also some x86 improvements too.
The multi-queue block layer (blk-mq) has indeed made it for Linux 3.13 as one (of many other) exciting features. The multi-queue block layer can lead to better SSD performance through reducing latency by balancing I/O workload across multiple CPU cores and allowing for multiple hardware queues.
The Russian Linux developers at ROSA have come up with a Linux kernel ABI tracker that monitors upstream versions of the kernel to record API and ABI changes.
Beyond the NVIDIA Tegra 4 support and improved 64-bit ARM code, the in-development Linux 3.13 kernel will also support EFI on ARM.
The merge window hasn't even officially opened yet on the Linux 3.13 kernel but it's already super exciting and I can't wait for the new code to start hitting mainline and to benchmark these massive changes to the Linux kernel. Here's just a few things to expect so far but it's already gearing up to be a super exciting release and perhaps the best of 2013.
The Linux 3.13 kernel merge window has become even more exciting even though it's not even officially open yet. Besides many to-be-merged changes talked about on Phoronix already, the ACPI and power management pull is particularly exciting for ARM and Intel Linux users.
SystemTap 2.4 has been released today for effective information gathering and software diagnostics on Linux systems. SystemTap 2.4 provides smarter error reporting, support for virtual machine probing using libvirt, and other new functionality.
While the Linux 3.13 merge window isn't opening until next week, the maintainer of the block layer to the Linux kernel isn't accepting anymore changes for this next kernel release. The merge pull for the block layer in Linux 3.13 is already quite large, in part due to merging the multi-queue block layer (blk-mq) support for faster disk performance. The multi-queue block layer will allow Linux to perform significantly better for disk IOPS while reducing latency with multi-queue SSD access on multi-core systems.
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.
