The Linux 3.3 kernel release might be imminent. In releasing the Linux 3.3-rc6 kernel, which Linus says is just made up of small fixes and clean-ups, he says this could be the last release candidate.
An interesting mailing list question was posed yesterday to DRM developers, which raises the question there might be a new Linux DRM kernel driver being hacked.
While this weekend saw the release of the Linux 3.3-rc5 kernel, which Linus Torvalds self-admitted was pretty boring, also hitting the mailing list this past week were new kernel patches to implement auto-sleep and "wake locks" support.
Linus Torvalds released the Linux 3.3-rc5 kernel this weekend. Overall, "it's been pretty boring, which is just how I like it."
A status report of the XFS file-system for January 2012 has been released. This report outlines some of then notable improvements made to this popular enterprise-grade Linux file-system for the Linux 3.2 and 3.3 kernels.
Brought up on the Linux kernel mailing list this week was a short-lived discussion whether Linux device drivers should be moved from kernel-space to user-space in an attempt to provide "greater security and robustness" of Linux systems.
While the Linux 3.3 kernel is still weeks away from release, there's more building up to look forward to with its successor: the Linux 3.4 kernel. A few months down the road when Linux 3.4 makes it out, there will be some additional Intel performance improvements.
After writing about Btrfs LZ4 compression support and that the Btrfs FSCK tool wasn't available, it turns out that there is the new Btrfs repair tool, but it's not widely known and it's not recommended to ever use it -- at least at this stage.
There's a new KMS/DRM driver to introduce to the world: UDL. UDL is a DRM kernel mode-setting driver for the USB-based DisplayLink graphics adapters.
The Linux 3.3-rc4 kernel was released this Saturday evening after a peculiar 32-bit kernel bug had led to the release being delayed by a few days.
A patch has been sent over to the Btrfs developers that can result in the next-generation Linux file-system being 5~10% faster in writes by introducing an extent buffer cache for each i-node.
Adding to the already existing Linux schedulers, including the out-of-tree Brain Fuck Scheduler (BFS), is now a proposal to integrate a new scheduler... The Barbershop Load Distribution scheduler.
VGEM, the Virtual GEM provider for the Linux kernel, is still being developed and a new version has been published.
The Linux 3.3 kernel is now up to its third RC release and is fairly in shape.
The proper solution to the Linux kernel ASPM power regression will finally be landing in the stable Linux 3.2 kernel series.
The second Linux 3.3 kernel release candidate is now available, which is coming a bit late due to Linus Torvalds falling behind.
Btrfs, the quite promising next-generation Linux file-system that's been in-development for years by Chris Mason and others, is about to take on a big role within Oracle's Enterprise Linux distribution.
Another one of the interesting talks that was recorded from Linux.Conf.Au in Ballarat, Australia last week was the presentation by Matthew Garrett. He went over the good and bad of UEFI support under Linux.
Chris Mason of Btrfs fame wasn't the only Linux file-system developer talking to the public last week. While the Btrfs talk was going on in Los Angeles at SCALE 10x, Dave Chinner was down under in Australia at LCA2012 talking about XFS. His talk included some controversial shots at EXT4 and Btrfs.
An fsck utility capable of fixing problems on the Btrfs file-system is imminent. Plus other features continue to be worked on for this next-generation, open-source Linux file-system.
While there's a lot of improvements in the Linux 3.3 kernel, it's not perfect. Here's some of what's unfortunately missing from this forthcoming kernel.
Linus Torvalds released the Linux 3.3-rc1 kernel on Thursday afternoon that marks the closure of the two-week Linux 3.3 kernel merge window.
Linus Torvalds has been called upon to pull the NVM Express driver into the Linux 3.3 mainline kernel.
Back in 2007 (the Linux 2.6.21 days) the mainline Linux kernel received tickless idle support. With the system idling, the timer tick no longer needlessly goes off with the "NOHZ" feature. Being worked on since last year is now adaptive tickless support, which extends the tickless functionality to non-idle cases.
On the same day as talking about Microsoft's new Resilient File System, the pull request for Btrfs in the Linux 3.3 kernel was sent in and subsequently pulled. This file-system update does bring a few notable changes.
Microsoft has released extensive details on their next-generation ReFS file-system to be introduced with Windows Server 8. How though does the file-system compare to Btrfs and the Linux file-systems?
New patches have been published for the Btrfs file-system that implement support for Google's Snappy compression algorithm, which promises to deliver better performance beyond LZO compression.
While the Frontswap patches with Cleancache have been available for several Linux kernel release cycles, the Frontswap support still hasn't been merged. Another Oracle developer is now taking over maintenance of Cleancache and getting Frontswap finally ready for merging, but it's too late for the Linux 3.3 kernel.
Alpha quality patches were published today that introduce the "Virtual GEM Provider" for the Linux kernel DRM, which can improve the software-based acceleration experience for graphics.
Queued up in the PCI sub-system pull for the Linux 3.3 kernel is the ASPM re-work that provides a proper fix to the well known Linux kernel power regression that was talked about for much of 2011.
