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.
There's more Linux 3.3 kernel news to report... This time it's the DRM pull request officially going in (and being accepted) as it's heavy on enhancements for open-source graphics drivers.
The EXT4 file-system pull request went in today for the Linux 3.3 kernel. The EXT4 updates for this next kernel include the new online resize interface.
The Linux 3.3 kernel staging pull request has been submitted to Linus Torvalds. As said by Greg Kroah-Hartman, the 3.3 staging merge is big and "overall, the story is pretty good."
Reiser4 is still not ready for integration into the Linux 3.3 kernel nor has the file-system even been officially updated yet for any of the recent kernel releases.
Last week a new I/O scheduler was presented for the Linux kernel. This new scheduler, FIOPS, is designed around modern flash-based storage devices like solid-state drives.
If you were hoping to see support for Microsoft's exFAT file-system land in the Linux 3.3 kernel, guess again.
Another feature coming to the Linux 3.3 kernel is Byte Queue Limits (BQL), which attempts to fight "bufferbloat" in networking.
Besides MythTV, Cube 2, and many other open-source projects, another high-profile project that's still around and kicking but that's been quiet as of late is the Zen Kernel.
The Radeon virtual memory (VM) support -- part of the Radeon HD 7000 series upbringing -- is now in the DRM next tree for landing in the Linux 3.3 kernel. Separate from the expected 3.3 graphics pull request, Linaro's "dma-buf" has already been sent to Linus Torvalds for merging into the mainline tree.
When talking yesterday about the likely DRM pull for the Linux 3.3 kernel there were a few graphics driver related items not on the list.
If you upgraded today to the just-released Linux 3.2 kernel and your Intel system is now having problems booting this new kernel release, you're not alone, but here's a possible workaround.
Now that the Linux 3.2 kernel is released, the Linux 3.3 kernel merge window is open. Here's a quick look at what should be queued up for the Linux 3.3 kernel when it comes to the DRM graphics area.
Linus Torvalds officially christened the Linux 3.2 kernel on Wednesday afternoon.
Seth Jennings of IBM has provided a patch for the next Linux kernel that removes the LZO-specific compression bits inside zcache and instead hooks this compressed page cache into the generic Crypto compression API.
After sharing the most popular Linux stories of 2011 in terms of Phoronix news articles, here is a listing of the most popular featured Phoronix articles from this past calendar year.
Ouch, Intel at the last minute has -- once again -- had to disable RC6 power savings support from their open-source Linux graphics driver for Sandy Bridge hardware.
