The Linux 3.1 Kernel May Have A New Logo

Back in 2009 the Linux mascot, Tux, was temporarily replaced by Tuz. Tuz was a Tasmanian Devil character and the use of the logo was used to promote this endangered animal that's nearly extinct in Australia. Tuz replaced Tux in the Linux 2.6.29 kernel, but with Linux 2.6.30 there was the return of Tux. Now with the Linux 3.1 kernel that's a proposal (RFC) for a new Linux kernel logo.

The Linux Foundation Falls In New Security Breach

There was the widely-reported Kernel.org security breach at the end of August, which resulted in the servers used for hosting the Linux kernel Git repository and other code to be forced off-line. Kernel.org has still not been restored, and now there's a related security breach at the Linux Foundation. Linux.com, the Linux Foundation itself, and related infrastructure are now "down for maintenance" this weekend.

Longene: The Linux Kernel With Windows Support

This morning after providing benchmarks of FreeBSD with Linux binary compatibility for gaming, which allows unaltered 32-bit Linux binaries to be executed seamlessly with the FreeBSD kernel (and in a rather fast manner), I was reminded on Twitter about another interesting project: Longene. Longene is a "Linux Unified Kernel" that attempts to implement Microsoft Windows APIs within the Linux kernel. In other words, Windows binary compatibility for the Linux kernel, including for Windows device drivers.

Linux 3.1-rc5 Tips Up On GitHub

For those that missed it, the Linux 3.1-rc5 kernel release has been widely reported as it's being hosted on GitHub. Due to the hacking of Kernel.org and bringing down the infrastructure until all systems are reinstalled, Linus Torvalds decided to move it over to GitHub temporarily.

VMware Graphics Prepare To Leave Staging Area

The VMware developers working on their "vmwgfx" graphics driver for Linux on their virtualization platform are preparing to have this driver leave the kernel's staging area and formally move into the Linux kernel DRM tree as one of the stable, mainline graphics drivers. But before this driver moves into the formal DRM tree, they are pushing a set of changes to clean up the kernel interface to this driver, which will break things in a non-backwards-compatible manner.

Samsung DRM Driver Could Make It Into The Kernel

Last week I wrote about Samsung releasing code to a new DRM driver for one of their ARM SoCs, the Exynos 4210 that's used by the Samsung Galaxy S II and other mobile devices. It looks like this open-source kernel driver from Samsung stands a chance as being the first ARM driver to be accepted into the DRM area of the mainline Linux kernel.

Linux 3.1-rc4: Bigger Than Its Predecessor

Linus Torvalds has released the Linux 3.1-rc4 kernel to end out the weekend. Unfortunately this kernel is on a trend he doesn't like: there's an up-tick in the commit rate compared to the previous release candidate for the Linux 3.1 kernel.

Interesting Talks For Linux Plumbers Conference 2011

Besides XDC Chicago 2011 for Linux graphics developers, coming up in just two weeks in Santa Rosa, California is the Linux Plumbers Conference. Here's some of the interesting talks expected at this event that's largely targeted for Linux kernel developers.

Intel Thunderbolt Support Under Linux

Earlier this year Apple introduced Thunderbolt ports on their new systems while more hardware vendors will be offering these next-generation high-speed connections on their systems going forward, particularly when the Ivy Bridge hardware is rolled out. Thunderbolt, which was developed under the Light Peak codename, can transfer data at 20 Gbit/s and offers much potential, but how's the Linux support?

Improving The Linux Kernel's Memory Performance

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.

New Plans For Linux Long-Term Kernel Releases

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.

Linux 3.1-rc2 Is A Fairly Calm Release

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.

The DRM Pull For The Linux 3.1 Kernel

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.

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.

Preparing For The Linux 3.1 Kernel

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.

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.
