The latest Raspberry Pi graphics driver hacking by Eric Anholt of Broadcom has been working to support QPU shaders by this open-source driver stack. QPUs are the shader core of the graphics hardware found in the Raspberry Pi SoC, but come up short of supporting OpenCL or OpenGL compute shaders.
David Airlie a short time ago submitted the Linux 4.9 DRM subsystem update, including the much sought after open-source Direct Rendering Manager driver improvements. There's a lot of good stuff in here, but sadly the Nouveau changes look like they're going to have to wait until Linux 4.10.
The non-volatile DIMM (NVDIMM) support has been updated for the Linux 4.9 kernel merge window.
While running the fresh NVIDIA vs. AMD Vulkan Linux benchmarks (that also included some OpenGL numbers too), I had also taken the opportunity to run some fresh OpenCL compute benchmarks of the latest NVIDIA 370 proprietary Linux driver against AMDGPU-PRO on different graphics cards.
There is support for a number of new ARM platforms with the in-development Linux 4.9 kernel.
Linux's power management and ACPI subsystems maintainer Rafael Wysocki presented at this week's LinuxCon Europe event in Berlin about the state and future of power management in the Linux kernel.
With the Linux 4.9 staging pull request comes the addition of the Greybus subsystem. A major user of the Greybus subsystem was to be Google's Project Ara modular smartphone, but with that initiative recently being canned, it may seem like Greybus is dead but that's not actually the case.
The input subsystem is the latest pull request to talk about for the forthcoming Linux 4.9 kernel development cycle.
Takashi Iwai sent in the sound subsystem updates for the Linux 4.9 kernel. This cycle there continues to be changes all over the place.
The x86/platform updates for the Linux 4.9 kernel that entered development on Sunday is bringing initial support for the Mellanox systems platform.
In the months ahead the Linux kernel should start receiving the work out of the "make-wifi-fast" initiative for improving WiFi reliability and performance.
The past few kernel releases there's been a redesign of CPUFreq and P-State code for being able to make use of the kernel's scheduler utilization data by these CPU frequency scaling drivers. That work also led to the introduction of the Schedutil governor. Work along this line has continued for Linux 4.9.
Purism, the startup behind the Librem laptops with a focus on free software and user privacy/freedom, still has their minds set on coming up with a GNU/Linux smartphone.
Here are some fresh benchmarks of various solid-state drives (SATA 3.0 SSDs plus two NVMe M.2 SSDs) as well as two HDDs for getting a fresh look at how they are performing using the Linux 4.8 Git kernel.
Lately I've heard a few reports of some newer PCs being less than friendly with Linux, namely a number of Lenovo devices who have issues with installing Linux. Based upon new information that's come to light from a Phoronix reader, it appears that PCs receiving Microsoft's "Signature Edition" tag are being locked-out from running non-Windows platforms.
Linux input developer Peter Hutterer of Red Hat has provided a look at the evdev protocol for those wondering about its design.
Similar to last year, unfortunately there is no Phoronix Oktoberfest meet-up in 2016 unlike in a number of years prior, as unfortunately I am missing the yearly pilgrimage/holiday.
Besides the Greybus subsystem being right around the corner for the mainline Linux kernel, it might not be too much longer before the TEE subsystem is ready. TEE is now up to its 12th patch revision and is about trusted computing.
An Intel developer continues working on the "Kernel NET Policy" as a step towards better and simplified network configuration for better performance.
Maxime Ripard of Free Electrons has sent in the Allwinner DRM driver pull request that will ultimately land for the Linux 4.9 kernel merge window.
Linux power management and ACPI maintainer Rafael Wysocki has published a set of new "iowait boost" patches for P-State and Schedutil that he's looking to see benchmarked by interested parties.
While it doesn't get talked about as much as Nouveau or Freedreno, the Etnaviv project has been another effort leading great progress on a full-functioning open-source graphics driver through reverse-engineering. Etnaviv is the reverse-engineered driver for Vivante graphics.
Linaro has announced the first development board that supports their 96Boards' Enterprise Edition TV Platform specification.
It's looking like the Raspberry Pi Zero might be playing fine out-of-the-box with the upcoming Linux 4.9 kernel cycle.
Two or so years back or so it was looking hopeful that the mainline Linux kernel would finally have a proper VIA DRM/KMS driver for the unfortunate ones still have VIA x86 hardware and using the integrated graphics. However, that work was ultimately abandoned but there is talk of it being restored.
The open, upgradeable ARM development board that traces back to the failed KDE Vivaldi project managed to pass its funding goal just in time. This open-source hardware project currently powered by some older Allwinner hardware managed to raise more than $170k.
It looks like some newer Intel laptops will be much happier when S3 suspended with the upcoming Linux 4.8 kernel.
For more than the past year I've been very much looking forward to AMD's Opteron ARM-based development boards. Sadly, these boards -- namely the HuskyBoard and LeMaker Cello -- are silently absent.
Razer keyboards, mice, and other peripherals are very popular with gamers. However, the company has never provided an official control UI / driver for managing their devices under Linux while various open-source projects have filled the void.
Eric Anholt of Broadcom has written a blog post detailing his past week of work on the open-source VC4 driver stack that benefits the Raspberry Pi.
