Linux Kernel News Archives
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.

Released last month was RapidDisk 1.0, which is a Linux kernel module that up to this point has received little attention on the Internet. RapidDisk is a new Linux RAM disk kernel module like the brd and zram modules, but with a different feature-set.

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.

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.
21 July 2011 - New Release
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."
5 July 2011 - The New 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.

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."

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.
