Intel Speed Select Technology Comes To Linux With The 5.3 Kernel

With the in-development Linux 5.3 kernel is now support for Intel Speed Select Technology (SST) that was introduced as part of Cascade Lake processors. Speed Select Technology allows optimizing the system with per-core performance configurations to prioritize certain workloads while lowering the performance envelope for other cores.

The Massive DRM Pull Request With AMDGPU Navi Support Sent In For Linux 5.3

At 479,818 lines of new code and just 36,145 lines of code removed while touching nearly two thousand files, the Direct Rendering Manger (DRM) driver updates for Linux 5.3 are huge. But a big portion of that line count is the addition of AMD Radeon RX 5000 "Navi" support and a good portion of that in turn being auto-generated header files. Navi support is ready for the mainline Linux kernel!

Char/Misc Has A Bit Of Changes All Over For Linux 5.3

The char/misc changes with each succeeding kernel release seem to have less changes to the character device subsystem itself and more just a random collection of changes not fitting in other subsystems / pull requests. With Linux 5.3 comes another smothering of different changes.

KDE's kstart5 Now Works On Wayland, No More HiDPI Screen Flickering At Start-Up

There is less than two months to go until KDE's annual Akademy conference, which this year is being hosted in Milan, Italy. But even with summer activities, KDE development remains quite busy. KDE developer Nate Graham has written another one of his weekly blog posts highlighting the interesting development work going into this open-source desktop environment.

NVIDIA's Graphics Driver Will Run Into Problems With Linux 5.3 On IBM POWER

For those using the NVIDIA proprietary graphics driver on an IBM POWER system, it could be a while before seeing Linux 5.3+ kernel support. Upstream has removed code depended upon by the NVIDIA binary driver for supporting the POWER architecture and as is the case they don't care that it will break NVIDIA driver support since it's binary/out-of-tree.

AMD Picasso Support For Coreboot Appears Finally Ready

Back in April I wrote about Coreboot seeing AMD Picasso APU enablement work as the first Zen/Ryzen processor target being handled by this open-source BIOS alternative. It now looks like that Picasso support is all squared away and ready for use by future AMD-powered Google Chromebooks.

Glibc's Slow Turnaround For Y2038 Fixes Is Frustrating

While there is another nineteen years to go until the Year 2038 problem manifests, the GNU C Library "glibc" is one of the key software components still needing some fixes for this issue where this problem where storing the Unix time as a 32-bit signed integer will wrap around and become a negative number.

Purism's Librem 5 July Update Cites Software Progress, No Hardware Update

Purism has shared their July update on their Librem 5 Linux smartphone progress, which is mostly focused around inching along their software support but without any update on their hardware or final design. While their latest public information has continued to report a "Q3" ship date, that's looking increasingly unlikely.

Initial Raspberry Pi 4 Performance Benchmarks

It's been (and still is) a particularly busy few weeks for benchmarking. For those curious about the Raspberry Pi 4 performance that was announced at the end of June along with Raspbian 10, here are our initial performance benchmarks of the Raspberry Pi 4 Model B in 2GB and 4GB variants compared to various other ARM SBCs.

Linux 5.3 Picks Up Support For Compressed Firmware Files - Measurable Storage Savings

With the growing number of devices requiring loadable firmware/microcode at run-time and Linux continuing to simply support a lot more hardware, the size of /lib/firmware has ballooned in recent years while now for the upcoming Linux 5.3 kernel release is the ability to compress these firmware files for fairly significant space savings.

The Performance Impact To AMD Zen 2 Compiler Tuning On GCC 9 + Znver2

One of the areas that I always have "fun" benchmarking for new CPU launches is looking at the compiler performance. Following the recent Ryzen 3000 series launch I carried out some initial benchmarks looking at the current Zen 2 performance using the newest GCC 9 stable series with its "znver2" optimizations. Here is a look at how the Znver2 optimizations work out when running some benchmarks on the optimized binaries with a Ryzen 9 3900X running Ubuntu 18.04 LTS.

GNOME Software Moving Forward With Disabling Snap Plugin

While currently Ubuntu makes use of GNOME Software as their "software center" (or "app store") with Snap integration, as we wrote about recently Canonical has begun writing their own Snap Store. Given this and that they don't plan to use GNOME Software in Ubuntu 20.04 LTS and thus have taken their developers away from working on the upstream support, GNOME developers are planning to disable the Snap plug-in for GNOME Software.
