MuQSS is the successor to the BFS scheduler and its first major release was last month for this scheduler that currently doesn't have any ambitions to go mainline. On OpenBenchmarking.org this weekend were some independent benchmarks of the new scheduler.
The sixth weekly test release of the Linux 4.9 kernel is now available while Linus Torvalds is still deciding how many more RCs to go before officially releasing this huge kernel update.
Jerome Glisse has sent out the latest version of his patches now for Heterogeneous Memory Management (HMM), which he's been working on the Linux kernel since 2014.
Red Hat developer David Howells has wrangled up a set of patches by him and other developers to provide a "Kernel Lockdown" mode to prevent the user-space from the possibility of modifying the running kernel image.
Adding to the list of new features coming for Linux 4.10 is support for explicit fencing for atomic DRM drivers.
The Linux 4.9 kernel will be officially released in about three weeks but there is already new features/functionality to get excited about for Linux 4.10.
Linus Torvalds released Linux 4.9-rc5 a few minutes ago as the latest weekly test release of the forthcoming Linux 4.9.
The Linux 4.10 kernel will likely see ZTE's "ZXDRM" display driver added.
Linus Torvalds has done another Saturday release of the latest Linux kernel release candidate.
DRM subsystem maintainer David Airlie submitted on Wednesday quite a number of fixes for the Direct Rendering Manager drivers. There's been fixes queueing up for a while that are now ready to go in after the nasty PAT regression fix has landed.
Linus Torvalds released the Linux 4.9-rc3 kernel as the latest test version of the massive Linux 4.9 code-base.
At the beginning of the month well-known independent kernel contributor Con Kolivas confirmed he was working on a new project called MuQSS as an evolutionary successor to his Brain F*** Scheduler. This Saturday morning he's now announced the first stable major release of MuQSS.
This morning I published the Power Consumption and Efficiency Of The Linux Kernel For The Last Three Years article containing power consumption data for an Intel Haswell system going back to the Linux 3.11 kernel through Linux 4.9 Git. Those were some interesting power consumption numbers under load while here are the idle numbers.
David Herrmann has posted the initial patches for review of the BUS1 kernel message bus, the successor to KDBUS as an in-kernel IPC mechanism.
Broadcom developer Eric Anholt's latest work on the VC4 DRM kernel driver for Raspberry Pi hardware is for enabling HDMI audio support.
Last week the Intel Turbo Boost Max 3.0 patches were updated for the Linux 4.9-rc1 kernel. While it won't be mainlined until Linux 4.10 at least, I decided to try out these TBM 3.0 / ITMT patches with a Core i7 6800K Broadwell-E CPU.
We're only up to Linux 4.9-rc2 but as usual Daniel Vetter has already prepared a pull request of drm-intel-next to begin staging Intel kernel graphics/display driver changes for Linux 4.10.
Linux 4.9-rc2 is now available as the latest test release of this forthcoming kernel update.
When having out the Core i5 "Sandy Bridge" HP EliteBook this weekend besides comparing fresh OpenGL numbers to early Sandy Bridge results going back to 2012, I also compared Ubuntu 16.10 / Linux 4.8 and Linux 4.9 compared to older kernel benchmarks I did with the same system.
Not mentioned in my earlier features you won't find in the Linux 4.9 mainline kernel is support for Intel's Cache Allocation Technology (CAT) but at least it was revised this weekend in still working towards mainline integration.
Earlier this year patches were posted for a new /dev/random implementation for the Linux kernel dubbed LRNG -- simply, the Linux Random Number Generator. The LRNG work has yet to be merged in the mainline kernel but the code has now been updated for Linux 4.9.
The perf code for Linux 4.10 is set to receive a new "c2c" tool.
Earlier this week I posted some benchmarks of a Core i7 6800K Broadwell-E system seeing performance boosts under Linux 4.9 and it turns out it's looking more widespread than just affecting a niche system or two. When testing a more traditional Intel Haswell desktop, Linux 4.9 Git is seeing more wins over Linux 4.8 and 4.7 kernels.
The supported Linux 4.8/4.7/4.4 kernel series have seen stable point releases today to address a new CVE security issue nicknamed "Dirty COW" that is a local privilege escalation issue and could allow attackers to overwrite files to which they don't own write access.
Now that Linux 4.9-rc1 is out, it's onward to testing this new Linux kernel on the dozens of test systems at Phoronix. With some early testing on a Core i7 6800K Broadwell-E box, there are some promising improvements.
While Linux 4.9-rc1 was only released this past weekend, the EFI subsystem changes are already being staged for the next kernel cycle.
While there are many new features in Linux 4.9, there is some functionality we've been looking forward to that sadly isn't yet in the mainline kernel tree.
With all the new features in Linux 4.9, obviously Tux put on a bit of weight this kernel cycle... Here's some numbers.
