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 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.
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.
Earlier today the F2FS file-system "major enhancements" were merged for the Linux 3.13 kernel and now we have pull requests issued for EXT4 and XFS file-system updates.
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 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.
As was anticipated, the Linux 3.12 kernel was released this afternoon. The Linux 3.12 kernel is a mighty big update but beyond announcing its debut, Linus Torvalds also made mention of a delay in the Linux 3.13 merge window and has begun expressing possible plans for a Linux 4.0 release in about one year's time.
With the Linux 3.12 kernel likely being officially released this evening if there are no last-minute delays, here is a look again at some of the top features and changes for this major open-source Linux upgrade.
The release of the Linux 3.12 kernel is imminent so here's a recap of some of the benchmarks we have carried out so far on this exciting kernel upgrade.
KTAP is a lightweight script-based dynamic tracing tool for Linux that remains independent of GCC and doesn't require kernel module re-compilation. KTAP 0.3 was just announced this morning and with it comes some more features.
The seventh -- and likely last -- release candidate for the Linux 3.12 kernel is now available. While late in the release cycle, there's been an uptick in new patches merged this week.
While the Linux 3.12 kernel hasn't even been released yet, going back to late August Intel has been plotting their graphics improvements for Linux 3.13. In September Intel was already sending in drm-next changes and they have done more rounds since. Another drm-next pull request was issued today for the Intel DRM driver.
The Linux 3.12 kernel brings faster open-source AMD graphics due to a CPUfreq subsystem change but there also appears to be faster disk performance.
Rob Clark has queued up some interesting changes to his "MSM" DRM driver for reverse-engineered open-source Qualcomm Snapdragon display support. The changes queued up for the Linux 3.13 kernel will include PRIME and render nodes capabilities.
