Linux 2.6.26 Kernel Released

We were up to nine release candidates with the 2.6.26 branch but today the Linux 2.6.26 kernel has been released. Since 2.6.26-rc9 were mostly documentation updates and a few regression fixes. The Linux 2.6.26 kernel x86 PAT, PCI Express Active State Power Management, KVM support for IA64 and PPC architectures, basic para-virtualization support for KVM, a UVC web-camera driver, OLPC support, new hardware drivers, and more. This kernel also brings updated ATI and Intel DRM, which includes the initial R500 3D support. A nice list of the changes for the Linux 2.6.26 kernel can be found at The Linux 2.6.26 kernel announcement can be read at

Linux 2.6.26-rc9 Kernel Released

If you were hoping that Linux 2.6.26-rc8 would be the last release candidate and the Linux 2.6.26 kernel would be released over the Independence Day weekend here in the US, guess again. There was enough fallout from the 2.6.26-rc8 release that Linus Torvalds has decided to issue a Linux 2.6.26-rc9 kernel release. This update brings a number of fixes, but there still are quite a few regressions and other problems. There are a few security fixes, fix Intel Mac booting with EFI, VFS fixes, and many other changes. Making up the bulk of the Linux 2.6.26-rc9 kernel is a new UVC video driver for the standard USB Video Class specification. The Linux 2.6.26-rc9 announcement can be read on

Linux 2.6.26-rc8 Kernel Released

It's only been a couple days since Linux 2.6.26-rc7, but today Linus Torvalds has released Linux 2.6.26-rc8, or what will hopefully be the last testing release for the Linux 2.6.26 kernel. The two changes making up most of this new release candidate are minor alterations to Xen and KVM virtualization. Linus will be gone for about a week, but he hopes this is the last release candidate before the Linux 2.6.26 kernel goes gold.

Kernel Developers Say No To Binary Blobs

The Linux Foundation and over 140 kernel developers have today issued a message reaffirming their position on binary-only drivers within the Linux kernel. Their positional statement reinforces that any closed-source Linux kernel module is harmful and undesirable. Their one paragraph decree goes on to add "we urge vendors to adopt a policy of supporting their customers on Linux with open-source kernel code." Their statement along with all of the Linux kernel developers agreeing with this message can be found at

Linux 2.6.26-rc7 Kernel Released

With the release of the Linux 2.6.26-rc7 kernel, the release of Linux 2.6.26 final is nearing. The big change in Linux 2.6.26-rc7 is the Intel and ATI DRM update we talked about earlier this week. That update brings R500 DRM support, updated microcode for all Radeon GPUs, and Intel GMA 4-Series (the upcoming X4500 Chipset) DRM support. Linus Torvald's mailing list message and short change-log can be read at Kernel Trap.

Updated Intel, ATI DRM For Linux 2.6.26

Red Hat's David Airlie has requested that Linus Torvalds pulls in a slew of DRM patches in time for the Linux 2.6.26 kernel release. The Linux 2.6.26-rc7 kernel will be out any day now, but David Airlie is requesting these patches get in as most of the work has been well-tested -- aside from the Intel GMA 4-Series work that was committed just days ago. These patches include all of the open-source R500 3D work for Mesa's DRM component, which will bless many users with this newly-found support. In addition, the patches include the new microcode for all Radeon GPUs that were officially released by AMD. While R500 is the major focus of this work, there are also a few DRM fixes for the earlier Radeon R100/200/300/400 generations (and the updated microcode helps these cards too). Last but not least, the Intel GMA 4-Series Chipset patches for DRM are included as well. David Airlie's e-mail message and all of the patches can be found on the mailing list archive.

Linux 2.6.26-rc6 Kernel Released

We're almost nearing an end to the Linux 2.6.26 kernel development with now six release candidates, but Linus Torvalds notes in his mailing list announcement that there are still more changes late in the game than what he'd ideally like to see. Between Linux 2.6.26-rc5 and Linux 2.6.26-rc6 have been 350 commits. As usual, most of the changes have taken place within the driver and architecture sections of the Linux kernel.

Linux 2.6.26-rc5 Kernel Released

Just like Linux 2.6.26-rc4, today's release of the 2.6.26-rc5 kernel is another update with a variety of small fixes. There isn't anything major to talk about with this latest testing kernel update other than fixing some scheduler issues and the usual assortment of driver updates. The release announcement and additional commentary can be found at Kernel Trap.

Linux 2.6.26-rc4 Kernel Released

With the Linux 2.6.26-rc4 kernel announcement Linus Torvalds goes on a bit of a rant surrounding users with a 32-bit x86 kernel but using PAE/HIGHMEM64G for supporting a greater memory capacity in excess of 4GB, but when you should be using the x86_64 kernel. However, for those of you in this situation, the Linux 2.6.26-rc4 kernel has a fix that should prevent some headaches caused by fallout from the recent PAT fix/cleanup patches.

Linux 2.6.25-rc9 Kernel Released

Most thought the Linux 2.6.25-rc8 kernel would be the last testing release before this new Linux kernel goes gold, but in fact -rc9 was released this afternoon. The Linux 2.6.25-rc9 kernel is quite a small update and consists mostly of Motorola m68k updates, network driver updates, and XFS file-system patches. Linus mentioned in the Linux 2.6.25-rc9 announcement that he's looking to release Linux 2.6.25 final early next week.

Linux 2.6.25-rc1 Kernel Released

With the final release of the Linux 2.6.24 kernel at the end of January, the first release candidate for Linux 2.6.25 is now out the door. With the long 2.6.24 development cycle, there is quite a few changes for the Linux 2.6.25 kernel and it includes 1.4 million lines of diffs which amounts to 11MB. Most of this work, however, boils down to architecture and driver updates. Of note in this release is the Intel video driver now working with suspend/resume natively, ACPI and other general suspend/resume changes, and many cleanups from the x86 merge.
