Rafael Wysocki has offered a glimpse at what's to be merged into mainline in the coming weeks for the Linux 3.9 kernel when it comes to ACPI and power management.
The Linux kernel RNG implementation for providing random numbers has worked quite well for its years in use. However, a new jitter entropy generator implementation has been proposed that is capable of providing 100 kB/s throughput of randomness.
A week has passed since the previous release candidate so Linus Torvalds has now tagged the Linux 3.8-rc7 kernel. This latest kernel release still isn't as quiet on development activity as he'd like, but it's getting better.
Greg Kroah-Hartman has confirmed he is working on an implementation of D-Bus for merging into the mainline Linux kernel.
While the Linux 3.8 kernel hasn't even been released yet, several of the noteworthy features slated to be merged for the Linux 3.9 kernel are already known.
David Herrmann has provided an update on his ambitious initiative to kill of the Linux kernel console. Herrmann has long been working on making the Linux kernel CONFIG_VT option unnecessary for providing a Linux console by punting it off to user-space. The Linux kernel VT console hasn't been changed much in the past two decades and Herrmann is hoping to see it replaced with a user-space solution he's been developing that would allow for multi-seat support, a hardware-accelerated console, full internalization, and other features.
RFC patches were published on Tuesday to provide digital signature protection support for initramfs.
A few weeks ago EnhanceIO's code for the Linux kernel was presented, a new SSD caching implementation for Linux. This code is now being prepared for merging into the Linux kernel's staging area.
While flying over to Brussels for FOSDEM, Linus Torvalds released the sixth Linux 3.8 kernel RC. Unfortunately this weekly development release is larger than Linus would like for this late in the development cycle.
The current Linux kernel CPU hot-plugging support has been described as "an increasing nightmare full of races and undocumented behaviour", but fortunately it's in the process of being re-developed.
Generating a fair amount of attention today is word that when booting modern versions of Ubuntu -- and other Linux distributions -- on Samsung laptops that utilize UEFI, Linux can actually brick the system. There's now an urgent Linux kernel patch underway.
Open-source developers are still pursuing the feat of building the mainline Linux kernel with the LLVM/Clang compiler rather than GCC.
The Reiser4 file-system has been ported to run on the Linux 3.7 kernel. Separately, TRIM/DISCARD support for Reiser4 on solid-state drives is being discussed amongst the remaining Reiser4 developers.
A set of patches that allow the Linux kernel image to be compressed with the LZ4 lossless compression algorithm have been published. The size of LZ4-compressed Linux kernel images are larger than using LZO compression, but there's promise that the boot times could be better.
A set of "controversial" patches were published by Matthew Garrett this morning for the Linux kernel. One of the patch series will disable the kernel's support for kexec and hibernate support when running in a UEFI Secure Boot environment.
The Tux3 file-system has been in development for years while back on 1 January, the file-system work was resurrected. There's now an initial fsck implementation for Tux3.
In early December, Imagination Technologies ended up publishing 28 thousand lines of Linux kernel code, which ended up being a port of the open-source kernel for their Meta ATP/HTP processor cores. This Linux kernel port is looking to be merged to mainline for the Linux 3.9 kernel.
The fifth RC for the Linux 3.8 kernel has been quietly released.
A Google engineer has proposed "Fast Queue Spinlocks" for the Linux kernel as an alternative in select cases to the default ticket spinlock.
From the Linux Foundation's Consumer Electronics Workgroup is a Linux 3.4 kernel that's part of their Long-Term Support Initiative. The LTSI Linux 3.4 kernel will be maintained for two years while back-porting some of the features of newer Linux kernel releases.
The DRM KMS locking re-work patch series is ready and has been queued up for merging into the Linux 3.9 kernel.
Last week on the Linux kernel mailing list was a proposal for an Aggressive Low Memory Booster. This is potentially an interesting feature for Linux systems with limited amounts of RAM.
The Linux kernel is still being ported to new hardware. One of the latest processor families that has been receiving a Linux kernel port is the Synopsys ARC700 series.
Linus Torvalds released the fourth release candidate of the Linux 3.8 kernel on Thursday evening.
An experimental system device hot-plug framework for the Linux kernel is still being developed. This framework is meant to be commomon for system device hot-plugging for system devices like CPU and RAM while being platform-neutral.
It's been a long time coming, but Bcache might finally be merged soon into the mainline Linux kernel. Bcache provides a block-layer SSD cache for Linux with write-back and write-through support for solid-state drives.
Here's some of the improvements that the Intel open-source Linux graphics driver will see with the Linux 3.9 kernel release.
The third release candidate to the Linux 3.8 kernel was issued on Wednesday evening.
A second version of the Zswap patch-set for the Linux kernel was published this week. The Zswap patches provide compressed swap caching support to compress pages in the process of being swapped and compresses them into a dynamically allocated RAM-backed memory pool.
There's ongoing work so that graphics cards can be assigned for use by virtual machines with QEMU.
