While we are just a few days into the Linux 3.8 kernel merge window and there's still a number of pull requests that have yet to appear for this next kernel development cycle with new features, there's already a ton of exciting work. If you missed the horde of Phoronix articles in the past few days covering the prominent features, here's a recap showing why this Linux kernel being developed over the holidays is a great gift for its users.
The FUSE module, which allows for file-systems to be run from user-space, can now process direct I/O a-synchronously. This a-synchronous direct I/O can lead to very noticeable performance improvements for FUSE-based file-systems like ZFS.
The Linux 3.8 kernel is continuing to pull in massive amounts of new code as shown by all of the noteworthy pull requests that have been highlighted on Phoronix in the past few days. The latest pull request to catch my interest has been the crypto work, thanks to performance-enhancing additions by Intel.
The audio/sound pull for the Linux 3.8 kernel has been sent in and it features audio driver improvements, new capabilities, clean-ups, and more.
For certain workloads with the Linux 3.8 kernel the physical memory usage is lowered by a significant amount thanks to improvements within this kernel that's presently under development.
Now that the Linux kernel has dropped support for old Intel 386 CPUs, GCC developers are also considering the removal of i386 support from their compiler.
While it might be too late to make the Linux 3.8 kernel merge window, released on Wednesday were the latest patches for the ongoing work by Intel open-source developers and others to enact atomic mode-setting and page-flipping.
Published to the Linux kernel mailing list were a set of patches to provide a new feature called Zswap for lightweight compressed swap caching.
Yet another change for the upcoming Linux 3.8 kernel is the removal of support for the old Intel i386 processors.
The latest pull request worthy of being mentioned for the Linux 3.8 kernel is the updates to the kernel's staging area.
ARM Holdings has more improvements for their ARMv8 AArch64 architecture with the Linux 3.8 kernel that just officially entered the first stages of development.
The ACPI and power management updates targeting the Linux 3.8 kernel were already submitted to Linus Torvalds this morning. There's a whole lot of new work to look forward to when it comes to power management in this next kernel.
One of the first pull requests sent in following the the Linux 3.7 kernel release is for getting closer to "true CPU hotplug support" with the Linux 3.8 kernel.
Linus Torvalds announced the release of the Linux 3.7 kernel on Monday night.
With the release of the Linux 3.7 kernel being imminent (it might even be out today), here's an overview of the features and highlights of this 2012 holiday release of the Linux kernel.
For those interested in Non-Unified Memory Access performance under Linux, here's an independent performance comparison that puts the mainline kernel against three other NUMA kernels.
Imagination Technologies has published a set of 44 patches that add in over 28,000 lines of new code to the Linux kernel.
The Linux Kernel A-synchronous I/O support has been receiving some performance improvements and clean-ups that should soon be merged to mainline.
Linus Torvalds decided to release Linux 3.7-rc8 on Monday rather than christening the Linux 3.7 kernel release. The final release will now come next week and the Linux 3.8 merge window will close right before Christmas.
For the past several months there has been work on vhost-blk, an in-kernel virito-blk device accelerator. This kernel-based accelerator can provide measurable speed-ups for disk/block device access by virtualized guest machines.
James Bottomley wrote a new blog post this morning about why the Linux Foundation really isn't concerned about UEFI SecureBoot on ARM hardware (smart-phones, tablets, etc) compared to the work they are doing on x86 PCs with UEFI SecureBoot support for Linux.
Linus Torvalds released the Linux 3.7-rc7 kernel on Sunday night and considers this new release candidate to be "slightly scarier" than the previous 3.7-rc6 release.
Various improvements to the major open-source Linux graphics drivers will be landing with the Linux 3.8 kernel in the months ahead.
Automatic NUMA Balancing has been quick to advance as it prepares for eventually merging into the mainline Linux kernel.
The sixth RC for the Linux 3.7 kernel is another calm release. Linus anticipates releasing a 3.7-rc7, but then we should see the final release in about two weeks time.
LDT has been published, a Linux Driver Template for helping new Linux kernel developers begin writing hardware device drivers.
For the past few days there has been a much-viewed and very polarized discussion happening on the Linux kernel mailing list about a possible GPL violation within the Linux kernel.
The Linux 3.7-rc5 kernel was releases on Sunday morning. It's a small weekly -rc release, which has left Linus Torvalds happy.
The Linux kernel has been ported to a new family of processors commonly found in TV set-top boxes, digital media players, and other devices.
The Linux 3.7-rc4 kernel was released on Sunday.
