Ralink Adds RT5390 Support To Open WiFi Driver

Back in September there was the major victory for the open-source and Linux hardware support communities when Broadcom open-sourced an 802.11n Linux driver after years of their WiFi chipsets being notorious under Linux. There's another wireless chipset vendor now getting more serious about open-source driver support too and that's Ralink. They've now contributed patches to the rt2x00 driver project that enables their new RT5390 chipset family to be used by this open-source Linux wireless driver.

An Update On Reiser4 For The Mainline Linux Kernel

In November of 2009 we reported that the Reiser4 file-system may go into the mainline Linux kernel in late 2010. We're now into 2011 with the merge window having closed earlier this month for the Linux 2.6.38 kernel and there's no sign of this open-source file-system designed to succeed the popular ReiserFS. So what gives? Well, we have another update from its lead developer.

The DRM Brings Some Fun To The Linux 2.6.38 Kernel

David Airlie has just called upon Linus to pull in his DRM tree for the Linux 2.6.38 kernel. With this being the first 2.6.38 DRM pull request and with the merge window still open, this code brings in a fair amount of exciting work. Here's what those using the popular open-source Linux graphics drivers can find in this next kernel release:

Linux 2.6.37-rc8 Kernel Ends Out The Year

For those hoping Linux 2.6.37-rc7 was the last release candidate of the Linux 2.6.37 kernel before going gold, it's not. Linus this evening decided to go ahead and make a Linux 2.6.37-rc8 release.

Linux 2.6.37-rc7 Kernel Released

While in recent years we have seen new Linux kernel releases on Christmas or Christmas Eve, this will not be the case in 2010. Linus has just released the Linux 2.6.37-rc7 kernel making it very unlikely to see any final release (or even another -rc) arrive this week.

Texas Instruments Puts Out A New Open-Source Driver

Earlier this week there was the release of a new open-source Linux driver by an engineer at Texas Instruments. The TI DMM-TILER is this new driver and its for the dynamic memory manager block on Texas Instruments hardware. "Its purpose is to organize video/image memory in a 2-dimensional fashion to limit memory bandwidth and facilitate 0 effort rotation and mirroring. The TILER driver facilitates allocating, freeing, as well as mapping 2D blocks (areas) in the TILER container(s). It also facilitates rotating and mirroring the allocated blocks or its rectangular subsections."

Linux 2.6.37-rc4 Kernel Released On Schedule

While Linus Torvalds spent most of last week in Japan meeting with other Linux kernel developers, the Linux 2.6.37-rc4 release is right on schedule, one week after releasing Linux 2.6.37-rc3. There are more changes found in this fourth release candidate than would be anticipated for this time in the release cycle, but the overall churn isn't too bad and there are a few notable fixes.

ZFS For Linux Is Now Available To The Public!

For those with some extra time this holiday week in the United States, perhaps you want to try out the ZFS file-system on Linux? As was said this week when publishing ZFS benchmarks on Linux using the native kernel module developed by LLNL/KQ Infotech, the public release of this kernel module wasn't going to happen until the first week of January. Fortunately, we have been successful in overwhelming KQ Infotech with lots of interested users, so they have decided to go ahead and make the current beta ZFS Linux module available to the general public.

Bringing Up Hardware First In Linux, Then Windows

After reading the Linux 2.6.37-rc3 release announcement on the Linux kernel mailing list, another interesting thread was found and it's about getting hardware vendors to do their initial hardware bring-up under Linux prior to any Microsoft Windows or Apple Mac OS X support. A number of reasons are provided why hardware vendors should support their hardware first under Linux and also why they should foster open-source drivers along with its challenges.

Linus: What's Wrong With The Whole DRM Crowd?

David Airlie sent in a DRM pull request to Linus Torvalds for the Linux 2.6.37 kernel this week to fix some Intel DRM driver bugs as well as one ATI Radeon KMS fix. However, this pull request sparked another rant by Linus Torvalds about the quality of the work of the open-source Linux (DRM) graphics driver developers.

Linux 2.6.37-rc2 Kernel Released; So Far Looks Painless

Two weeks have passed since the release of the Linux 2.6.37-rc1 kernel that finally allowed the core kernel code to built without the the Big Kernel Lock. It also brought many open-source graphics improvements and other improvements and new drivers (such as a Intel Poulsbo driver and Broadcom's WiFi driver). Now the Linux 2.6.37-rc2 kernel is available as regressions are addressed in time for the final Linux 2.6.37 kernel release several weeks down the road.

Ted Ts'o: EXT4 Within Striking Distance Of XFS

There's just two months to go until the annual Linux.Conf.Au conference, which in 2011 is taking place in Brisbane, Australia. Ted Ts'o, the maintainer of the EXT4, will be speaking at the 2011 Linux.Conf.Au and he's just shared his "money shot" from his presentation about this evolutionary file-system building atop EXT2/EXT3. New benchmarking results from HP's Eric Whitney on a large multi-core system indicate that "[EXT4 is] now within striking distance of XFS."

The Main DRM Pull Request For The Linux 2.6.37 Kernel

David Airlie has just called upon Linus Torvalds to pull in his DRM kernel tree for the Linux 2.6.37 kernel merge window. We have talked about many of these features before that are now entering the mainline Linux kernel code-base as new capabilities of the open-source Linux graphics stack, but here's the list of what made the cut for Linux 2.6.37 and details on some of the features we have yet to discuss.

Three Things That Won't Be In The Linux 2.6.37 Kernel

While the Linux 2.6.36 kernel was released yesterday, we already have our eyes towards the Linux 2.6.37 kernel to see what new features this next kernel will bring, any performance changes that may come as a result (we continue to benchmark the kernel everyday), and this will likely be the kernel version used by Ubuntu 11.04 and other early 2011 Linux distributions. While we have already reported on some of the features that should be merged into the Linux 2.6.37 kernel, there's at least three major features we have been looking forward to that will be sadly missing from this kernel.
