While Linux has supported WOL (Wake-On-LAN) for wired network adapters, the Linux 3.1 kernel prepares support for WWOL, or Wake On Wireless LAN.
Over the past few days there's been an active discussion on the Linux kernel mailing list surrounding the memory copy (the memcpy function to copy blocks of memory) performance within the kernel. In particular, an application vendor claims to have boosted their application (a video recorder) performance by 12% when implementing an "optimized" memory copy function that takes advantage of SSE3.
Greg Kroah-Hartman has laid out his plans this morning for handling Linux kernel releases in the future that will be supported for the long-term. The proposal is quite simple and is not handled radically different from now with regards to kernel releases that are maintained for extended periods of time.
Linus Torvalds released the Linux 3.1-rc2 kernel on Sunday afternoon. There isn't too much to see and Linus notes that this is a fairly calm release for coming just one week after the close of the Linux 3.1 kernel merge window.
Linus Torvalds officially released the Linux 3.1-rc1 kernel on Sunday afternoon, following the 3.1 merge window being open for more than two weeks.
David Airlie has called upon Linus Torvalds to pull in his DRM Git tree that offers the key Direct Rendering Manager graphics driver improvements for the Linux 3.1 kernel.
The latest feature to be pulled into the Linux 3.1 kernel is support for OpenRISC, an open-source CPU architecture.
After not being updated for a few mainline kernel release cycles, the real-time (RT) Linux kernel has been updated against the Linux 3.0 kernel release.
Officially marking the introduction of Linux 3.x, Linus Torvalds this evening announced the official release of Linux 3.0.
Oracle's latest acquisition is that of Ksplice Inc, the company behind the software to apply updates to the Linux kernel in real-time without requiring a system reboot or other downtime. "Never Reboot Linux For Security Updates," as Ksplice says.
Linus Torvalds is expected to release the Linux 3.0 kernel today. He has announced that the last-minute bugs that held up the Monday release should be addressed and he's preparing for the Linux 3.1 kernel merge window to be opened.
While it looked like the Linux 3.0 kernel was near based upon last week's Linux 3.0-rc6 release, Linus Torvalds has decided to do one last release candidate based upon last minute changes.
Linus Torvalds released the Linux 3.0-rc6 yesterday in celebration of Independence Day in the United States. It includes a new driver that has received praise and Linus believes it's due to "space aliens are secretly testing their happy drugs on Christoph."
There's still a few more weeks left until the Linux 3.0 kernel will be officially released, but there are already some changes worth looking forward to with the Linux 3.1 kernel as it pertains to the Direct Rendering Manager drivers.
Being proposed by Ohad Ben-Cohen for integration into the mainline Linux kernel is a generic AMP/IPC framework. This a-symmetric multi-processing (AMP) framework with inter-process communication (IPC) integration makes it possible to control remote processors and communicate messages with these remote processors. This work is the primary target of modern SoC devices.
Linus Torvalds has released the Linux 3.0-rc5 kernel on this Monday evening. Around 25% of the changes in this week's release candidate are driver related while file-system changes account for nearly half and the rest of the work is scattered throughout.
For the multiple Linux kernel power regressions that I've talked about on Phoronix now for a number of weeks and have been affecting mobile Linux users en mass, I said I was looking for a better power measuring approach by using an AC power meter / UPS rather than a notebook battery to use in nailing these regressions. Using such a power meter would lead to a fully-automated process by the Phoronix Test Suite as no longer would I need to keep pulling the power plug from a laptop, could use much faster hardware, and allow for some other interesting possibilities. Well, last week I bought a power meter that plays with Linux. So now there's some news to share.
Yesterday I mentioned what Anton Altaparmakov of Tuxera had recently said about their NTFS kernel driver being the fastest Linux file-system, which erupted into a large debate in our forums. Within that mailing list thread was also another interesting comment by Linus Torvalds. "Userspace filesystem? The problem is right there. Always has been. People who think that userspace filesystems are realistic for anything but toys are just misguided."
Linus Torvalds has announced the release of the Linux 3.0-rc4 kernel.
The Linux kernel power regressions in the Linux 2.6.38 where I was the first to largely document and prove would cause major power problems in Ubuntu 11.04 and other Linux distributions, continues to bite plenty of mobile users.
The second -rc release for the Linux 3.0 kernel is rather quiet and not too exciting. Linus pushed out this new kernel release in the early hours of the morning.
Beyond the features of the Linux 3.0 kernel already talked about on Phoronix, there's another big milestone hit in this next kernel release beyond changing up the versioning scheme. The Linux 3.0 kernel will have full Dom0 and DomU support for Xen virtualization.
For those that missed it, now that I've been back in the office for a few weeks and caught up on the other benchmarks and articles for May and beginning the work for June, I'm back to looking into the Linux kernel power regressions reported more than a month ago -- i.e. Linux Has Major Power Regression and Another Major Linux Power Regression Spotted.
Beyond file-system cleancache support, a Microsoft Kinect driver, Intel Ivy Bridge support, and various open-source graphics driver improvements, the Linux 3.0 kernel may also reboot your system better. Yes, really.
For anyone that was doubting Linus Torvalds would finally part ways with the Linux 2.6 kernel series, you lost your bets. On the eve of Memorial Day in the United States and his departure to Japan for LinuxCon, Linus Torvalds just tagged Linux 3.0-rc1 in Git.
While the first Phoronix benchmarks of EXT4, Btrfs, and XFS on the Linux 2.6.39 kernel were just published this morning, an interesting change was just made for the next Linux kernel that will affect many of the file-systems living within the kernel. For what will be the Linux 2.6.40 kernel, or rather the Linux 3.0 kernel is the finally-merged support for CleanCache.
The discussion surrounding Linus Torvalds' proposal to end the Linux 2.6 kernel series and continue on as the Linux 3.0 kernel has continued on since it began less than 24 hours ago. The reaction has largely been positive and supportive of this proposed change. Of the few objections, some see no reason to mess around with the versioning, but now there may be a reason for this change: to drop the old cruft that's been living in the kernel.
While it's not known yet what the next Linux kernel will be called, right now it's looking like the next release could be the Linux 3.0 kernel. With that said, David Airlie has a pull request to go in before the merge window closes for the Linux 2.6.40/3.0 kernel. He's sent in the DRM pull request for this next kernel as the Gardenshed-rc1 kernel.
It was just a few hours ago that we were the first news site to point out the message by Linus Torvalds on the kernel mailing list about his desire to end the Linux 2.6 kernel series and move future releases to the Linux 2.8 or even Linux 3.0 series. While efforts to change the Linux kernel versioning have been voiced in the past and ultimately failed, it looks like the effort this time around is building momentum and the change could very well happen.
In a message to the Linux Kernel Mailing List today regarding the shortened merge window for the Linux 2.6.40 kernel, Linus Torvalds brings up that there's already been many Linux 2.6 kernel releases and that he could end up tagging this as the Linux 2.8.0 kernel.
