Daniel Poelzleithner has announced to the Linux kernel world his new project named ulatencyd. The focus of ulatencyd is to provide a script-able daemon to dynamically adjust Linux scheduling parameters and other aspects of the Linux 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:
The stable Linux 2.6.37 kernel has now been released. This is the Linux kernel that incorporates Broadcom's new WiFi driver, proper Intel Sandy Bridge support, Btrfs file-system improvements, many open-source graphics DRM/KMS updates, and much more.
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.
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.
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."
With it being just over a week since the release of Linux 2.6.37-rc5, Linus Torvalds has this evening put out Linux 2.6.37-rc6. This seventh release candidate to the Linux 2.6.37 kernel is just packing regression fixes as it nears completion.
For those interested in testing out the very latest Linux kernel code, the Linux 2.6.37-rc5 kernel is now available for use.
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.
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.
One week after the relatively painless Linux 2.6.37-rc2 release came about, the third release candidate for the Linux 2.6.37 kernel has come around.
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.
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.
As anticipated, the 2.6.37 merge window closed yesterday and the first release candidate for the Linux 2.6.37 kernel is now available. Major changes that were pushed into the Linux 2.6.37 kernel include support for building the kernel without the Big Kernel Lock (BKL), many graphics DRM improvements, and more of the responsiveness patches.
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.
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.
The Linux 2.6.36 kernel is now out there on the Internet. After an unexpected delay and some other slowdowns in the 2.6.36 development cycle, Linus tagged the 2.6.36 kernel this afternoon.
While we are close to seeing the Linux 2.6.36 kernel, this week LinSched for the Linux 2.6.35 kernel was released. LinSched is a simulator that allows testing the Linux kernel scheduler in user-space for modifying and observing its scheduling behavior.
While last week it looked like the Linux 2.6.36 kernel was just days away with Linus Torvalds expecting the 2.6.36-rc7 release to be the last test milestone, this has turned out not to be the case as this afternoon a 2.6.36-rc8 kernel has made a debut.
As was anticipated seven days ago when releasing the Linux 2.6.36-rc6 kernel, there is a Linux 2.6.36-rc7 kernel to come and it's just been released. The good news is that Linus Torvalds believes this will be the last release candidate before the Linux 2.6.36 kernel is officially released.
The Linux 2.6.36 kernel is just about here. Linus Torvalds has now released the sixth RC build of this upcoming 2.6.36 build. In the past week since 2.6.36-rc5 was released, there's been many more regression fixes going into the kernel, but still it's not in a state ready for release by Linus' standards.
The Linux 2.6.36-rc5 kernel is now available after Linus Torvalds has got back on track with the weekly release candidates after being at LinuxCon in Brazil. Of course, this later release candidate just targets correcting bugs and other issues, including a fix for a 14 year old kernel bug.
Alban Crequy, a Maemo developer, for the past several weeks have been working on bringing D-Bus directly into the Linux kernel. Why? Huge performance improvements.
Due to LinuxCon Brazil there's been two weeks that have passed since the third release candidate was tagged for the Linux 2.6.36 kernel, but on Sunday afternoon Linus christened Linux 2.6.36-rc4.
While we are always getting excited for the next Linux 2.6 kernel release (heck, we are barely halfway through the Linux 2.6.36 kernel development and we are already getting excited for Linux 2.6.37 with its driver improvements), but sometimes it can be easy to forget that there is still a maintained Linux 2.4 kernel. The Linux 2.6 kernel has been around for nearly seven years and is used by all new Linux distribution updates, but there's lots of enterprise and embedded devices running off this old kernel. The Linux 2.4 kernel though may have just reached an end-of-life state with the just-released Linux 126.96.36.199 kernel.
Linus Torvalds has just done a Sunday afternoon release of the Linux 2.6.36-rc3 kernel. With the merge window for the Linux 2.6.36 kernel having closed a few weeks ago, the third 2.6.36 release candidate isn't too exciting unless you were affected by one of the kernel's outstanding bugs.
About one month ago we reported on the emergence of patches that may fix the Linux desktop responsiveness problems, which is an issue that's been experienced by many Linux desktop users in recent years. For Linux users it may take many seconds for a menu to appear when clicking on it or a half-minute to do a VT switch, but fortunately it's becoming a thing of the past with these patches working well for many users and has since been integrated into the mainline Linux kernel. The story though is not over as even more patches have just been published to further improve the Linux desktop responsiveness.
The Linux 2.6.36-rc2 kernel has been released this Sunday afternoon and this time around there's an announcement of the release by Linus Torvalds (he lacked announcing 2.6.36-rc1; Phoronix was one of the few places reporting on it). The 2.6.36-rc2 kernel release brings mostly bug/regression fixes, but compared to the Linux 2.6.35 kernel, Linus has accepted some pull requests after the -rc1 release in the Linux 2.6.36 kernel while denying other requests.
Kernel mode-setting (KMS) is useful for faster VT/X switching, VTs being always at the panel's native resolution, the ability to thwart some security bugs in the X.Org Server (as shown earlier this week), presenting a cleaner and more flexible architecture, and allowing new and interesting projects to emerge (such as Plymouth and Wayland), but the benefits do not end there. When kernel mode-setting is combined with KDB, a Linux kernel debugger shell, you now have one powerful combination.
The Linux 2.6.36-rc1 kernel was released earlier in the week and while it will still be a couple months until the Linux 2.6.36 kernel will be officially released, the developers behind the open-source DisplayLink graphics driver are already looking forward to the Linux 2.6.37 kernel. This next kernel release that will make it out in early 2011 will bring new features and fixes to this driver that supports many graphics products over USB.
