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 184.108.40.206 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.
While this weekend saw the release of the Linux 3.3-rc5 kernel, which Linus Torvalds self-admitted was pretty boring, also hitting the mailing list this past week were new kernel patches to implement auto-sleep and "wake locks" support.
Linus Torvalds released the Linux 3.3-rc5 kernel this weekend. Overall, "it's been pretty boring, which is just how I like it."
Brought up on the Linux kernel mailing list this week was a short-lived discussion whether Linux device drivers should be moved from kernel-space to user-space in an attempt to provide "greater security and robustness" of Linux systems.
While the Linux 3.3 kernel is still weeks away from release, there's more building up to look forward to with its successor: the Linux 3.4 kernel. A few months down the road when Linux 3.4 makes it out, there will be some additional Intel performance improvements.
There's a new KMS/DRM driver to introduce to the world: UDL. UDL is a DRM kernel mode-setting driver for the USB-based DisplayLink graphics adapters.
The Linux 3.3-rc4 kernel was released this Saturday evening after a peculiar 32-bit kernel bug had led to the release being delayed by a few days.
Adding to the already existing Linux schedulers, including the out-of-tree Brain Fuck Scheduler (BFS), is now a proposal to integrate a new scheduler... The Barbershop Load Distribution scheduler.
VGEM, the Virtual GEM provider for the Linux kernel, is still being developed and a new version has been published.
The Linux 3.3 kernel is now up to its third RC release and is fairly in shape.
The proper solution to the Linux kernel ASPM power regression will finally be landing in the stable Linux 3.2 kernel series.
The second Linux 3.3 kernel release candidate is now available, which is coming a bit late due to Linus Torvalds falling behind.
Another one of the interesting talks that was recorded from Linux.Conf.Au in Ballarat, Australia last week was the presentation by Matthew Garrett. He went over the good and bad of UEFI support under Linux.
While there's a lot of improvements in the Linux 3.3 kernel, it's not perfect. Here's some of what's unfortunately missing from this forthcoming kernel.
Linus Torvalds released the Linux 3.3-rc1 kernel on Thursday afternoon that marks the closure of the two-week Linux 3.3 kernel merge window.
Linus Torvalds has been called upon to pull the NVM Express driver into the Linux 3.3 mainline kernel.
Back in 2007 (the Linux 2.6.21 days) the mainline Linux kernel received tickless idle support. With the system idling, the timer tick no longer needlessly goes off with the "NOHZ" feature. Being worked on since last year is now adaptive tickless support, which extends the tickless functionality to non-idle cases.
While the Frontswap patches with Cleancache have been available for several Linux kernel release cycles, the Frontswap support still hasn't been merged. Another Oracle developer is now taking over maintenance of Cleancache and getting Frontswap finally ready for merging, but it's too late for the Linux 3.3 kernel.
Alpha quality patches were published today that introduce the "Virtual GEM Provider" for the Linux kernel DRM, which can improve the software-based acceleration experience for graphics.
Queued up in the PCI sub-system pull for the Linux 3.3 kernel is the ASPM re-work that provides a proper fix to the well known Linux kernel power regression that was talked about for much of 2011.
There's more Linux 3.3 kernel news to report... This time it's the DRM pull request officially going in (and being accepted) as it's heavy on enhancements for open-source graphics drivers.
The Linux 3.3 kernel staging pull request has been submitted to Linus Torvalds. As said by Greg Kroah-Hartman, the 3.3 staging merge is big and "overall, the story is pretty good."
Last week a new I/O scheduler was presented for the Linux kernel. This new scheduler, FIOPS, is designed around modern flash-based storage devices like solid-state drives.
Another feature coming to the Linux 3.3 kernel is Byte Queue Limits (BQL), which attempts to fight "bufferbloat" in networking.
Besides MythTV, Cube 2, and many other open-source projects, another high-profile project that's still around and kicking but that's been quiet as of late is the Zen Kernel.
The Radeon virtual memory (VM) support -- part of the Radeon HD 7000 series upbringing -- is now in the DRM next tree for landing in the Linux 3.3 kernel. Separate from the expected 3.3 graphics pull request, Linaro's "dma-buf" has already been sent to Linus Torvalds for merging into the mainline tree.
When talking yesterday about the likely DRM pull for the Linux 3.3 kernel there were a few graphics driver related items not on the list.
