While Samsung has its Exynos 4210 DRM merged into the Linux 3.2 kernel as the first DRM driver for ARM in the mainline kernel, they haven't stopped there. More patches have been floating around from Samsung in the past few days.
There's long been a desire to have a KMS-based console program that can tie in with OpenGL, but none of the active DRM developers have yet to get around to writing such a "kmscon" program. However, Jesse Barnes has written a fairly in-depth guide for anyone wishing to write a standalone program using EGL and KMS with OpenGL. As Jesse says, "just in case anyone wants to port the VTE widget and give me my VTs on a cube."
The PCI subsystem pull for the Linux 3.2 kernel was published on Friday evening. If you were hoping it would rework PCI-E ASPM (Active-State Power Management) to be more like the Windows implementation or for more PCI drivers to be setting the bits directly to support it (effectively white-listing drivers/hardware), it didn't happen yet.
David Airlie sent in the main DRM pull request for the Linux 3.2 kernel to Linus Torvalds.
Just as the Linux 3.2 kernel merge window opened, NVIDIA published a set of patches that enable support for their Tegra 3 (Kal-El) processor.
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.
Edward Shishkin, the lone developer that took over development of the Reiser4 file-system following the conviction of Hans Reiser, has shared a new update with Phoronix regarding the efforts towards pushing Reiser4 into the mainline Linux 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.
