Linux overcame most of its former driver woes years ago except for one noticeable exception: Wi-Fi drivers. While many Wi-Fi cards and chipsets were Linux friendly, two major Wi-Fi chipset vendors, Atheros and Broadcom, kept their drivers proprietary. Now, things are changing. Atheros has released a true open-source driver for its latest 802.11n chipsets.

Linus has released the 2.6.25 kernel. After nearly three months of development and the merging of over 12,000 patches from almost 1200 developers, this kernel is now considered ready for wider use.

With the end of the next kernel version's main development phase, the most important new features of Linux 2.6.33 have been determined: DRBD, Nouveau, support of the Trim ATA command and a bandwidth controller for block devices. The developers have also improved the Radeon drivers and the support of Intel Wi-Fi chips.

The next version of Linux is not only the first to offer the Nouveau KMS graphics driver for NVIDIA graphics hardware, it also comes with a multitude of improvements for the two AMD/ATI and Intel graphics drivers which support Kernel-based Mode Setting (KMS).

The filesystem used in the vast majority of Linux (and to a lesser extent on other Unix) distributions is the ext3 filesystem, which stands for extended filesystem. Slashdot recently pointed to an article on IBM DeveloperWorks discussing the new ext4 filesystem currently in development, and some of its new features. So what is a filesystem really?

One month ago Nvidia released their 180.22 video drivers for Linux OSes, which brought initial support for Linux kernel 2.6.28. Last night (February 11th) Nvidia proudly presented yet another improved version of their proprietary video driver for the Linux, FreeBSD and Solaris open source operating systems.

« With the recent discussion here on proprietary blobs in the Linux kernel, it's nice to see that today Sam Leffler has released the source for the Atheros Hardware Abstraction Layer under the ISC license, which is both GPL and BSD compatible. The Atheros chipset is used in many laptops, so this is another important step towards running a completely free distribution. »

Linus Torvalds has released the first RC of Linux 2.6.34 and completed the integration of the next version of the kernel's most important changes. Improvements include graphics drivers for recent Radeon GPUs and for the graphics cores of some Intel processors that are only expected to be released early next year. Another new addition is the LogFS solid-state storage file system.

The latest version of Linux offers a whole host of new features – for example a USB 3.0 infrastructure, drivers for the Sound Blaster X-Fi, KMS support for Radeon chips and improved versions of Btrfs and Ext4. As is traditional with new Linux versions in the main development branch, however, this is only the tip of the iceberg.
