Oracle Just Bought Out Ksplice

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.

Linux 3.0-rc7 Kernel Released; One Last Hit?

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.

Linux 3.0-rc6 Kernel: Space Aliens & Drugs

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."

DRM Changes Coming Up For Linux 3.1 Kernel

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.

A Generic AMP/IPC Framework For Linux

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.

Linux 3.0-rc5 Kernel Release Brings Various Fixes

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.

Burning Through Power: Linux Regressions Found

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.

Torvalds: User-Space File-Systems, Toys, Misguided People

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."

The Linux Kernel Power Issues Continues To Bite Users

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.

Linux 3.0 Kernel Has Full Support For Xen

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.

Nailing Down The Linux Kernel Power Regressions

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.

The Linux 3.0 Kernel Will... Reboot Better?

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.

Say Hello To Linux 3.0; Linus Just Tagged 3.0-rc1

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.

CleanCache Merged Into The Linux Kernel

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.

Linux 3.0 Kernel May Remove Some Old Cruft

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.

The DRM Pull For The Gardenshed (Linux 3.0) 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.

The End Of The Road For Linux 2.6 Looks Likely

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.

Linus Talks Of Linux 2.8 Or Linux 3.0; Ending Linux 2.6

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.

What Not To Expect From The Linux 2.6.40 Kernel

Since the release of the Linux 2.6.39 kernel on Thursday, Linus Torvalds opened the merge window for the Linux 2.6.40 kernel and it will stay open until month's end. While the 2.6.40 kernel will bring several open-source graphics driver improvements (performance improvements, Intel Ivy Bridge support NVIDIA Optimus, etc), new hardware enablement, and other enhancements, there's a few features that you will not find in this next major Linux kernel release.

The Linux Kernel Is Still On A Power Binge

It's been about three weeks since last mentioning the major power consumption problem in the Linux kernel (actually, there's more than one power regression) and it's affecting distributions like Ubuntu 11.04. The lack of mentioning the power regression in recent weeks isn't though because the regressions are addressed, they are still outstanding with the about to be released Linux 2.6.39 kernel.

Linux 2.6.39 Kernel Is Imminent

"So things have been pretty quiet, and unless something major comes up I believe that this will be the last -rc," began Linus Torvalds in announcing the release of the Linux 2.6.39-rc7 kernel.

Speeding Up The Linux Kernel With Your GPU

Sponsored in part by NVIDIA, at the University of Utah they are exploring speeding up the Linux kernel by using GPU acceleration. Rather than just allowing user-space applications to utilize the immense power offered by modern graphics processors, they are looking to speed up parts of the Linux kernel by running it directly on the GPU.
