One of the technological advantages that Sun's Solaris (and OpenSolaris) operating systems have over Linux is their ZFS file-system. ZFS has a number of features not found on any of the current-generation Linux file-systems and its a technology many Linux users (especially those in data centers) have long desired.

The Linux 2.6.26 kernel was released just hours ago, but it's now time to look forward to the next update due out later this year, the Linux 2.6.27 kernel. As a prerequisite to kernel-based mode-setting and TTM / GEM memory managers entering the mainline Linux kernel, David Airlie has reorganized the DRM (Direct Rendering Manager) source-code tree to present in a much cleaner hierarchy.
13 July 2008 - It Means KMS & TTM/GEM Are In Sight
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 KernelNewbies.org. The Linux 2.6.26 kernel announcement can be read at LKML.org.
13 July 2008 - The Linux 2.6.25 Kernel Has A Successor - 4 Comments
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 LKML.org.

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.
25 June 2008 - Xen, KVM Virtualization Updates
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 LinuxFoundation.org.

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.
21 June 2008 - Another RC Kernel Release - 11 Comments
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.
20 June 2008 - A Big DRM Update Late In 2.6.26 Cycle - 1 Comment
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.
12 June 2008 - Another Week, Another RC
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.
5 June 2008 - A few more RCs before final
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.

With a week going by since the Linux 2.6.26-rc2 kernel release, Linus Torvalds has today announced the release of the Linux 2.6.26-rc3 kernel. This update is mostly made up of driver updates. The Linux 2.6.26-rc3 release announcement can be read at LKML.org.
20 May 2008 - Linux Kernel Driver Updates
On the LKML, Linus Torvalds has announced the release of the Linux 2.6.26-rc2 kernel. Since the Linux 2.6.26-rc1 kernel, just under half of the committed work has gone into architecture updates with the remainder of the work going towards drivers and miscellaneous work. Linus mentions that the most noticeable change is with the BKL, or the old Big Kernel Lock.
12 May 2008 - Linux 2.6.26 Is Two Steps Ahead
The Linux 2.6.25 kernel had shipped in the middle of April and now the first release candidate to this kernel's successor (Linux 2.6.26) is available for download. Among the changes in the Linux 2.6.26-rc1 kernel are x86 PAT support, file-system updates (including EXT4), a generic 802.11 layer, and mainline kgdb support for kernel debugging. The Linux 2.6.26-rc1 release announcement can be read at LKML.org.
3 May 2008 - Linux 2.6.26 Kernel Excitement
It's coming a bit late but Linus Torvalds had released the Linux 2.6.25 kernel late last night. The Linux 2.6.25 kernel introduces new EXT4 file-system improvements, ACPI thermal regulation, LatencyTOP kernel support, enhanced process memory usage management, and real-time group scheduling are among the major additions. The Linux 2.6.25 kernel also has the initial ATI R500 DRM support. The release announcement can be read at LKML.org. It's now time to start getting excited for the next Linux release... the Linux 2.6.26 kernel!

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.

The 2nd Linux Foundation Collaboration Summit has just kicked off down in Austin, Texas. The first Linux Foundation Collaboration Summit was held last year at the Googleplex, which Phoronix had also covered. We'll be providing coverage this week of the LF summit of interesting happenings.
8 April 2008 - LF Summit In Texas
Last week the Linux 2.6.25-rc7 kernel was released, which many expected would be the last -rc release before final, but that has changed. Linus Torvalds last night pushed out the Linux 2.6.25-rc8 kernel with a few fixes and the most noticeable regression fixes being for suspend and resume and input layer breakage. The Linux 2.6.25-rc8 release announcement can be read at Kernel Trap.
2 April 2008 - One More RC Before Final?
The Linux 2.6.25 kernel should be out quite soon, but this morning the Linux 2.6.25-rc7 kernel has been released. The changes in this release should close the last of the recent regressions and other trivial changes. Of note to X.Org enthusiasts are a few DRM fixes, which we mentioned were coming right after the -rc6 release with RV550 and PCIGART fixes. The Linux 2.6.25-rc7 release announcement can be read at LKML.org. It looks like the Linux 2.6.25 kernel will be an early April release.
26 March 2008 - One More RC Before Final? - 8 Comments
With just about a week passing since Linux 2.6.25-rc5, the sixth release candidate for the upcoming Linux 2.6.25 kernel has been released. Most changes in Linux 2.6.25-rc6 deal with architecture, documentation, and driver updates. One note about this release is that the Linux 2.6.25 kernel now has the device ID AHCI support for the upcoming NVIDIA MCP7B motherboard chipset.
