Jean Delvare, a name commonly associated with the LM_Sensors project while being an employee at SUSE, has raised an important discussion item on the kernel mailing list about improving the kernel configuration (Kconfig) options when building the Linux kernel.
The first release candidate to the Linux 3.15 kernel is now available and it marks the close of the kernel merge window for about two months. Linux 3.15 is poised to be a very exciting kernel release.
There's likely just a day or two left before the Linux 3.15-rc1 kernel will be released to mark the end of the Linux 3.15 kernel merge window. With all of the major features appearing to have been merged by now, here's an overview of the exciting features to look forward to with the Linux 3.15 release.
Early on in the Linux 3.15 merge window there were improvements to significantly speed-up suspend and resume for systems, but now there's another late merge of a patch that has the capability of speeding up the resume time from suspend by 7~12x for at least some laptop/desktop systems.
Experimental Linux kernel code for providing a Thunderbolt driver that works on Apple MacBook Pro systems has been updated and is still hopeful for its eventual mainline kernel inclusion.
The x86 platform driver update was pulled today for the Linux 3.15 kernel, which includes new notebook support.
Yesterday patches were published via a pull request to enable experimental LTO support for the Linux 3.15 kernel, but Linus Torvalds hasn't yet decided whether he will accept this code in the upstream Linux kernel... Linus doesn't yet see the benefits in link-time optimizations for the kernel and isn't sure whether this code is ready yet to be mainlined.
A second staging pull was submitted for the Linux 3.15 kernel that adds the new r8723au driver for handling an increasingly used WiFi adapter common to some new notebooks/ultrabooks.
The very large DRM pull request for the Linux 3.15 kernel was submitted just moments ago with significant updates to the open-source Linux graphics drivers.
As a potentially significant performance win for the Linux kernel, when compiling the Linux kernel support for link-time optimizations (LTO) are now supported.
For those not keeping up to date on all of the Phoronix articles covering the Linux 3.15 kernel changes that landed in the past week, here's a recap of the changes that were merged so far half-way through the Linux 3.15 merge window.
Linux kernel developers have been discussing for the past few days about the possibility of encoding kernel oops messages into QR codes that would be shown on the screen.
The Linux 3.15 kernel's /dev/random implementation will feature a new instruction of Intel's upcoming Broadwell processors.
File-systems implemented via FUSE (File-Systems in User-Space) will be getting better write throughput performance when upgrading to the Linux 3.15 kernel.
Published on the Linux kernel mailing list for review on Wednesday was per-cgroup swap file support.
The Kernfs code that's a split of the sysfs logic to make it more useful to other kernel subsystems wishing to have a virtual file-system, will get better in Linux 3.15.
While the Linux 3.15 kernel is introducing a large number of new features, it's also doing away with some old drivers and older x86 platforms.
Landing a few hours ago into the drm-next code-base for merger into the Linux 3.15 kernel in the days ahead is the universal/primary plane support for the Direct Rendering Manager drivers.
There's many updates to the sound drivers within the Linux 3.15 kernel that's now officially under development.
It was decided at last week's 2014 Linux Foundation Collaboration Summit that for inspiring a new wave of kernel developers and becoming more interactive with the community, patch review will become more social via handling patch reviews on Facebook.
The latest exciting set of kernel changes to mention for the Linux 3.15 kernel are some scheduler enhancements.
Another interesting change that's already landed for the Linux 3.15 kernel is infrastructure work for supporting x86 kernels optimized via LTO for yielding better kernel performance.
The libata pull request for the Linux 3.15 kernel is large due to AHCI changes.
Landing into the latest Linux kernel code for version 3.15 is EFI mixed mode support that will allow 64-bit kernels to run from 32-bit EFI firmware.
As expected after writing about the imminent Linux 3.14 a few hours ago, Linus Torvalds did a late Sunday night release of this next major kernel upgrade... There's new hardware support, stabilized Intel Broadwell graphics support, the SCHED_DEADLINE scheduler, AMD Cryptographic Coprocessor support, TCP auto-corking, Kernfs, and a whole lot more.
While no official announcement has come down yet, the Linux 3.14 kernel will most likely be released in the hours ahead.
KTAP has been public for the better part of two years as a dynamic tracing tool for the Linux kernel but only now it looks like this kernel tool will be merged to the mainline tree.
SUSE engineers will attempt to merge their kGraft live kernel patching mechanism into the mainline Linux kernel.
The Tux3 file-system has been in development since 2008 but it looks like in the next kernel release or two we will likely see it merged into the mainline Linux kernel.
With another Linux Foundation Summit means another time to hear an update about LLVMLinux, the Linux Foundation backed project to build the mainline Linux kernel with LLVM's Clang C/C++ compiler in place of GCC.
