Kristian Høgsberg has announced that the work he and Jesse Barnes, Jakob Bornecrantz, and Chris Wilson have been working on for the past few months is now ready for prime-time action. This work is the mode-setting page-flip ioctl for the kernel DRM. What this work basically leads to is tear-free updating of the screen with low-latency page-flipping.
It has been almost two weeks since the release of the Linux 2.6.31-rc5 kernel but this afternoon there is a new kernel available. Linus has made the release of Linux 2.6.31-rc6, which brings a number of small fixes throughout the Linux kernel. The changes are scattered throughout the different areas, including drivers, architectures, file-systems, etc.
Ready to test out a new kernel? Well, hopefully, as Linus Torvalds has just announced the Linux 2.6.31-rc5 kernel in time for the weekend. The Linux 2.6.31-rc5 kernel will reportedly fix a number of regressions that were present in Linux 2.6.31-rc4 and earlier and there are some other updates too. The changes in Linux 2.6.31-rc5 are scattered throughout, but there is an updated ATI kernel mode-setting module worth noting along with a few new Linux drivers.
The Linux 2.6.31 kernel will be released within the next month or so and one of the new features in this release is the long-awaited integration of the TTM memory manager and then appearing as a staging driver in this kernel is an ATI kernel mode-setting driver. This KMS driver doesn't yet support the newer R600/R700 GPUs, but it does support the R500 series and will be used by default in the forthcoming release of Fedora 12.
For those of you following the latest kernel developments, the Linux 2.6.31-rc4 kernel has just been released. This fourth release candidate for the Linux 2.6.31 kernel brings fixes for some bigger bugs that were discovered in the past week. These bugs, which are now corrected in 2.6.31-rc4, impacted binutils, ccache, and the compiler. Beyond that there are some small bug fixes and other work going on within the Linux 2.6.31-rc4 kernel.
Last week VIA re-released their Chrome 9 DRM in hopes of pushing it into the mainline Linux kernel. However, the only user of this DRM code at present is their Linux binary graphics driver and VIA Technologies has no intentions of providing an open-source Chrome 9 3D driver. However, within a month or so, VIA claims to be releasing a new 2D driver that can use this DRM to some extent. This whole situation with VIA has reignited the discussion over what to do when a company is interested in pushing an open-source DRM driver into the mainline Linux tree, but it's really only used by closed-source user-space drivers.
Just a bit more than a week has passed since the release of the Linux 2.6.31-rc2 kernel, but Linus Torvalds has today replaced that with the third release candidate in the Linux 2.6.31 series.
Quite a lot has made its way into the Linux 2.6.31 kernel, particularly Radeon kernel mode-setting and the new TTM GPU memory manager, but now the merge window for this release cycle is closing. Linus Torvalds last night released Linux 2.6.31-rc1 as the first test release of this new code. Besides the new graphics work within the Direct Rendering Manager side, this kernel boasts various new drivers, enhancements to other drivers, and updates to existing file-systems.
There have already been a few DRM pull requests to go into the Linux 2.6.31 kernel for making better the Linux graphics driver stack, but David Airlie now looks to have one more last minute pull before the merge window closes.
Last week a pull request went in to bring support in the Linux 2.6.31 kernel for Radeon kernel mode-setting and TTM memory management. This initial work was proposed to enter the Linux kernel as a staging driver and then be setup as a proper Linux kernel driver in the next release, Linux 2.6.32.
David Airlie has asked Linus Torvalds to pull in the TTM memory manager and Radeon kernel mode-setting code into the Linux 2.6.31 kernel.
Less than a day after the TTM memory management code was pushed out for review, the ATI kernel mode-setting driver is now getting ready for entrance into the Linux kernel too. Jerome Glisse has now announced on the kernel mailing list (as well as the DRI development list) that the Radeon KMS code is ready for review.
Just as planned, Linus Torvalds has released the Linux 2.6.30 kernel. Linux 2.6.30 introduces the NILFS2 file-system, new and updated drivers, support for the Microblaze CPU architecture, and many other changes. The release announcement for the Linux 2.6.30 kernel can be read at LKML.org.
Around this weekend Linus Torvalds is expecting to release the Linux 2.6.30 kernel. This kernel is home to a few performance improvements, new drivers, updated drivers, new file-systems, and many other improvements in this quarterly Linux update. However, to squeeze in some last minute testing before going final, Linus has released the Linux 2.6.30-rc8 kernel.
For those around the computer this holiday weekend in the United States, Linus Torvalds has announced the seventh release candidate for the Linux 2.6.30 kernel.
Late last night the Linux 2.6.30-rc6 kernel was released by Linus Torvalds. With development work on the Linux 2.6.30 kernel slowing down, there are only about 300 commits that make up this new release candidate. Some of the fixes include that of a PowerPC architecture update, Intel i915 DRM fixes, NILFS2 and ReiserFS file-system updates, Serial ATA updates, and various other small fixes.
Development work on the forthcoming Linux 2.6.30 kernel is slowly winding down as is indicated by this afternoon's release of the Linux 2.6.30-rc5 kernel. This latest 2.6.30 build has a few driver and architecture updates small file-system updates, and other regression fixes scattered throughout.
With the Linux 2.6.29 kernel a new logo was introduced to raise awareness for the Tasmanian Devil, a small animal nearing extinction. This interim logo was called Tuz while the traditional Tux penguin had "went on vacation", well, with the Linux 2.6.30-rc4 kernel, Tux has returned.
Ending off a week of testing with the Linux 2.6.30-rc2 kernel, Linus has announced the release of Linux 2.6.30-rc3. In this new test release are some x86 updates, a Btrfs update, and various other changes. The 2.6.30-rc3 announcement with the short changes can be found at LKML.org.
Last week Linux 2.6.30-rc1 was released, but this afternoon Linus Torvalds has pushed out the second release candidate for the Linux 2.6.30 kernel series.
Two weeks have passed since the release of the Linux 2.6.29 kernel that brought Intel kernel mode-setting, the Btrfs file-system, and many other improvements to the Linux kernel. Now though the first release candidate for the forthcoming Linux 2.6.30 kernel is now out in the wild.
The merge window for the Linux 2.6.30 kernel is now open and Linus has already accepted a horde of new patches for this next quarterly Linux update. Among what has been pulled in so far is the DRM (Direct Rendering Manager) support for a new Intel chipset. This new Intel IGP is described by Intel's Shaohua Li as "a G33-like desktop and mobile chipset." The patch adds in two new product IDs (0xa001 and 0xa011) for the desktop and mobile version and makes some clock-related changes. Within the code, the chipset is referred to as just an IGD (Integrated Graphics Device) rather than being more descriptive like the I945GM, I965GM, and GM45 defines.
Tux, the Linux penguin mascot, will be taking a break during the Linux 2.6.29 kernel cycle. Committed to the Linus's kernel tree last night is a new temporary logo known as Tuz. Tuz is a Tasmanian Devil, which is a species in danger of becoming extinct. The Tasmanian Devil is native to Australia and during this year's Linux.Conf.Au conference it was decided that Tuz will stand in for Tux for one kernel release in order to raise awareness for this creature. Tux will return with the release of the Linux 2.6.30 kernel.
In what will hopefully be the last test release, Linus has announced the Linux 2.6.29-rc8 kernel. This release brings a variety of fixes including a few Intel DRM tweaks, Blackfin architecture changes, a couple ALSA fixes, and a temporary fix for an Intel Atom bug. Overall there isn't anything too particularly interesting with this release candidate.
This month we will see the release of the Linux 2.6.29 kernel. This updated kernel will bring kernel mode-setting support on Intel hardware, the Btrfs file-system, the mainlining of SquashFS, improved EXT4 support, and other new features. If you are interested in helping to test this new kernel before it goes gold, the Linux 2.6.29-rc7 kernel was pushed out last night.
In March we should see the release of the Linux 2.6.29 kernel with the addition of Intel kernel mode-setting, the Btrfs file-system, and numerous driver improvements, but those that want to see a good and well-tested release should provide a hand in testing out the latest release candidate. Linus Torvalds last night pushed out Linux 2.6.29-rc6.
As of late, file-systems have been a popular topic among Linux developers and users. The EXT4 file-system was recently stabilized and it brings some modest performance improvements and is finding its way into modern distributions. While not yet stabilized, the Btrfs file-system was merged into the Linux 2.6.29 kernel and is poised as the Linux competitor to Sun's famed ZFS file-system. There is also open-source work underway in supporting Microsoft's exFAT file-system on Linux. On top of all of that, there is also the Tux3 file-system.
Work on the Linux 2.6.29 kernel is slowly winding down, and as a sign of that, Linus Torvalds had announced the release of Linux 2.6.29-rc5. This fifth release candidate has nearly 90% of the changes within the network drivers section due to a bnx2 firmware update and then nearly 5% from a staging USB driver. Beyond that there are also a few Intel DRM fixes worth noting. For the Linux 2.6.29-rc5 kernel release announcement, head on over to LKML.org.
A week and a half has gone by since the release of the 2.6.29-rc3 kernel, but the fourth release candidate for the Linux 2.6.29 kernel is now available. This release is targeted at just addressing regressions, with most of the work being done within Linux drivers and architecture updates. There are also a few fixes in place for the recently merged Btrfs file-system.
Development work on the Linux 2.6.29 kernel had slowed down a bit due to Linux.Conf.Au taking place last week, but the third release candidate has now been issued. There's a variety of bug-fixes and minor updates through the Linux kernel in 2.6.29-rc3, but nothing particularly exciting. Catching our eyes were just a few DRM updates (small work on GEM and KMS) and just a variety of driver updates.
