A set of Direct Rendering Manager patches have appeared to ease the development of targeting DRM drivers for embedded systems. There's also two new DRM drivers using this SDRM layer.
A patch was volleyed into the Linux kernel development camp to change the default I/O scheduler for non-SATA disk drives.
Development on the Linux 2.4 kernel is now officially over with no more maintenance releases being expected.
Just in time for some Easter weekend testing, Linus Torvalds has released the second RC of the Linux 3.4 kernel.
Chris Mason, the Oracle engineer who's the lead developer of the Btrfs, just finished a session at the Linux Foundation Collaboration Summit about his promising and feature-rich file-system.
The pull happened last week prior to the Linux 3.4-rc1 release, but one of the other interesting changes in the Linux 3.4 kernel that hasn't been talked about much is the x32 support.
Another noteworthy session from this year's Linux Foundation Summit was two Oracle engineers talking about DTrace on Linux.
A patch emerged out of IBM yesterday so that the Linux kernel can now has optimal SMP efficiency by being able to support running off zero CPU cores.
Patches for an x86 disassembler for the Linux kernel have been proposed. An in-kernel disassembler could prove useful for developers in cases of kernel panics and other happenings.
Linus Torvalds has put out the first release candidate for the forthcoming Linux 3.4 kernel.
As the latest work queued up for merging in the Linux 3.4 kernel is the Btrfs file-system pull, which Chris Mason describes as "pretty big, picking up patches that have been under development for some time."
David Airlie has a last-minute pull request for the Linux 3.4 kernel following last week's main DRM pull. This latest Git pull request is set to introduce DMA-BUF PRIME support in the mainline kernel.
There's a number of DRM-related updates today in the open-source Linux graphics world.
Con Kolivas announced this weekend the release of an updated BFS scheduler for the recently-released Linux 3.3 kernel. The new BFS scheduler is at version 0.420 and is codenamed "Smoking", with "a fairly large architectural change" since earlier versions of this out-of-tree kernel scheduler.
The PCI pull request went in yesterday for the Linux 3.4 kernel. Overall it's a fairly uninteresting pull for the 3.4 cycle, but there's two basic exceptions.
The main DRM graphics pull landed this afternoon for the Linux 3.4 kernel. David Airlie of Red Hat sent in the main DRM pull, which was followed-up by the Radeon HD 7000 / Trinity pull and then an unexpected Nouveau Kepler / de-staging pull. All of the code made it into the kernel, though Linus is complaining about some GCC warnings.
A patch has been proposed for the Linux kernel to introduce the VMUFAT file-system.
Just one day after the Linux 3.3 kernel was released, the power management pull request for the Linux 3.4 kernel has already been submitted.
Linus Torvalds officially released the Linux 3.3 kernel on Sunday afternoon.
On Thursday there was a new upstream contribution by Canonical for an Apple GMUX device driver, which can provide hybrid graphics support under Linux for certain Apple MacBook laptops.
Besides the DRM work already piling up for Linux 3.4, there's more. The Samsung developers responsible for the Exynos graphics driver have sent in their "-next" pull request, which brings several new features, including the basis of 2D acceleration for this open-source ARM graphics driver. There's also a virtual display driver that could be used for handling wireless displays.
For those that don't closely follow the various development lists, at the end of February a Silicon Motion developer came to the DRI list announcing he had "a kernel driver for all our graphics chips" that he was looking to mainline. It sounds nice, but in the end it's a let-down and the most you'll probably get out of it is a few laughs.
With the final release of the Linux 3.3 kernel expected to happen in in a matter of days, here's a recap of some of the most prominent Linux 3.3 kernel features that were introduced this cycle.
While it looks like there's still another week before the Linux 3.3 kernel will be released and thus marking the merge window for the Linux 3.4 kernel opening, here's some of the DRM graphics changes you can expect to see merged.
While last week it looked like the final release of the Linux 3.3 kernel was imminent, this didn't end up exactly being the case. Due to an up-tick in patches being merged this week, Linus Torvalds decided to go ahead and tag Linux 3.3-rc7 on Saturday afternoon.
The merge window for the Linux 3.4 kernel will open up this month assuming the latest Linux 3.3 release plans work out. One of the features to look forward to out of Linux 3.4 will be the DRM driver support for Intel Medfield graphics.
Towards the end of last year a new effort was initiated to mainline more of the Android changes inside the Linux kernel. Work has been progressing on that front and with the Linux 3.4 kernel more of these changes will land.
On Sunday marked the release of the 58th point release for the Linux 2.6.32 kernel by Greg Kroah-Hartman. The Linux 22.214.171.124 kernel now marks the passing of this kernel series into its extended-long-term maintenance window.
The Linux 3.3 kernel release might be imminent. In releasing the Linux 3.3-rc6 kernel, which Linus says is just made up of small fixes and clean-ups, he says this could be the last release candidate.
An interesting mailing list question was posed yesterday to DRM developers, which raises the question there might be a new Linux DRM kernel driver being hacked.
