Fedora 20 Will Ship With The Linux 3.11 Kernel

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.

Defeating Secure Boot With Linux Kexec

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.

The DRM/KMS Drivers In The Linux 3.13 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.

Linux 3.6 To Linux 3.13 Kernel Power Consumption Tests

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.

zRAM Is Still Hoping For A Promotion

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.

SquashFS Getting Major Performance Enhancements

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.

Random Is Faster, More Randomness In Linux 3.13

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.

The Major DRM Graphics Update Sent Into Linux 3.13

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.

Btrfs File-System Changes Published For Linux 3.13

The Linux 3.13 kernel brings major enhancements to Samsung's F2FS file-system but the EXT4 and XFS changes aren't too exciting. How are the Btrfs changes for this next kernel? We now know thanks to a new pull request from Chris Mason.

Multi-Queue Block Layer Is Merged For Linux 3.13

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.

F2FS File-System Major Linux 3.13 Enhancements

For those in need of a high-performance specially-optimized file-system for flash storage devices, the F2FS file-system developed at Samsung has seen more "major enhancements" queued up for the Linux 3.13 kernel.

The Linux 3.13 Kernel Is Already Super Exciting

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.

ACPI, Power Management Get Big Linux 3.13 Updates

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.

Linux 3.13 To Receive Multi-Queue Block Layer

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.
