The DMA-BUF PRIME support in the popular open-source Linux graphics drivers is coming together for the Linux 3.5 kernel to allow for GPU offloaded rendering.
BCache for the Linux kernel is still being worked on and is now up to its thirteenth revision prior to being merged into the mainline Linux kernel. BCache provides write-through and write-back caching as a new block device.
Ubuntu 12.10, the Quantal Quetzel, is likely to ship with the Linux 3.5 kernel. However, the Ubuntu kernel team will reserve the option to ship with Linux 3.6 if time and interest allows.
Linus Torvalds released the Linux 3.4-rc6 kernel on Sunday and signalled that the final release of the Linux 3.4 kernel is in sight.
A virtual Cirrus KMS driver has once again appeared for providing kernel mode-setting support for virtualized guests using QEMU.
The Linux 3.4-rc5 kernel was released on Sunday with an increased number of changes over its predecessor, which Linus Torvalds describes as annoying, but it shouldn't be "hugely scary" for those testing it out.
A kernel mode-setting (KMS) driver for new hardware has been published.
Linus Torvalds released the fourth release candidate of the Linux 3.4 kernel on Saturday afternoon. He believes the final Linux 3.4 kernel is still on track, but he's not too enthusiastic about the bombarding of new pull requests that seems to happen on Fridays.
There's already a number of changes building up when it comes to the Direct Rendering Manager (DRM) sub-system for merging into the Linux 3.5 kernel.
Linus Torvalds announced the release of the Linux 3.4-rc3 kernel on Sunday evening.
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.
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.
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.
