It seems to be a good time to clean-up the Linux graphics driver stack. After old hardware support was dropped in Mesa in August, more Mesa code was dropped, and most recently the classic ATI R300/R600 drivers are to be killed (this is set to happen this Friday). Now Intel's Daniel Vetter is chopping up some DRM code.
The Linux Foundation has announced this morning from Prague at LinuxCon Europe 2011 that they will be backing long-term support Linux kernel releases. In a move that targets consumer electronic devices relying upon the Linux kernel, once per year an LTS Linux kernel will be tagged and it will be maintained for a period of two years.
Linus Torvalds was worried that the Linux 3.2 kernel might be of a worrying size due to the belated release of Linux 3.1. Merge requests are now starting to come in for the Linux 3.2 kernel and the staging merge alone touches several hundred thousand lines of code.
In the early hours of the morning, Linus Torvalds tagged the Linux 3.1 kernel final.
After going through ten release candidates, the Linux 3.1 kernel should be released by early next week. However, with the Linux 3.1 kernel release cycle having been dragged on by more RCs than normal and the Kernel.org hacking incident, the Linux 3.2 kernel may end up being abnormally large and its worrying Linus Torvalds.
If you have an affected motherboard to the ASPM power regression in the Linux kernel and it's from Gigabyte, don't expect a BIOS update from them to correct the ASPM semantics in the BIOS. Gigabyte recommends you just use Microsoft Windows.
Development of the Linux 3.1 kernel has dragged on with Linus Torvalds releasing the Linux 3.1-rc10 kernel.
Texas Instruments has put out a new version of its DRM/KMS Linux driver for OMAP platforms as it prepares to hopefully see this open-source graphics driver merged into the mainline Linux kernel.
There's been a Linaro memory management working group for the past year to figure out memory management APIs and unify the memory management landscape for Linux graphics. One of the fruits of this work is now a DMA buffer sharing mechanism that was put out by Texas Instruments.
The Linux 3.1 kernel should be released any day now after going through nine test releases, which will be followed by the opening of the Linux 3.2 kernel merge window. Here's some of the DRM improvements to look forward to in this next major kernel release.
Linux kernel developers have marked Oracle's VirtualBox Linux kernel driver as "tainted crap" due to the overwhelming number of problems this module has caused.
While it's rare for there to be more than seven or eight (weekly) release candidates before a new major Linux kernel release, this evening Linus Torvalds has tagged 3.1-rc9.
It looks like the Samsung Exynos4 DRM driver that first publicly appeared in August will soon be merged into the mainline Linux kernel as the first open-source DRM driver within the kernel for an ARM SoC.
It's been nearly one month since Kernel.org was hacked -- the home to the Linux kernel source-code repository, among other services -- but it's still not back online yet.
For some non-X non-graphics news today, the Linux 3.1-rc6 kernel was released on Wednesday by Linus Torvalds.
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.
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.
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.
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.
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.
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.
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.
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.
Linus Torvalds announced the Linux 3.1-rc3 kernel last night. Overall there isn't a whole lot that's been changed in this development kernel over the past week.
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?
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.
