GRUB Now Supports Btrfs 3/4-Copy RAID1 Profiles (RAID1C3 / RAID1C4 On Linux 5.5+)

When it comes to the storage/file-system changes with the in-development Linux 5.5 kernel one of the most prominent end-user-facing changes is more robust RAID1 for Btrfs with the ability to have three or four copies of the data rather than just two copies, should data safety be of utmost importance and concerned over the possibility of two disks in an array failing.

Debian Developers Take To Voting Over Init System Diversity

It's been five years already since the vote to transition to systemd in Debian over Upstart while now there is the new vote that has just commenced for judging the interest in "init system diversity" and just how much Debian developers care (or not) in supporting alternatives to systemd.

Google Reaffirms Commitment To Kotlin Programming Language For Android

The Kotlin programming language on Android has become very popular and Google announced today nearly 60% of the top 1,000 Android applications are using Kotlin code in some capacity. Beyond their announcement earlier this year of Android development being Kotlin-first, as they look forward to 2020 will be more Kotlin + Android action.

Systemd-homed Looks Like It Will Merged Soon For systemd 245

Announced back in September at the All Systems Go event in Berlin was systemd-homed as a new effort to improve home directory handling. Systemd-homed wants to make it easier to migrate home directories, ensure all user data is self-contained, unify user-password and encryption handling, and provide other modern takes on home/user directory functionality. That code is expected to soon land in systemd.

RadeonSI NIR Benchmarks Show Great Progress With Mesa 20.0

With AMD last week having enabled OpenGL 4.6 for their RadeonSI OpenGL Linux driver when enabling the NIR intermediate representation support, you may be wondering how using NIR is stacking up these days compared to the default TGSI route. Here are some benchmarks on Polaris, Vega, and Navi for comparing this driver option that ultimately allows OpenGL 4.6 to be flipped on.

A General Notification Queue Was Pushed Back From Linux 5.5 Introduction

Red Hat has been working on a "general notification queue" that is built off the Linux kernel's pipe code and will notify the user-space of events like key/keyring changes, block layer events like disk errors, USB attach/remove events, and other notifications without user-space having to continually poll kernel interfaces. This general notification queue was proposed for Linux 5.5 but has been pushed back to at least 5.6.

GCC 10's C++20 "Spaceship Operator" Support Appears To Be In Good Shape

One of the prominent additions coming with the C++20 programming language is the consistent comparison operator, or "spaceship operator" as it's commonly referred to. The support was merged for GCC 10 last month ahead of entering stage three development while this week some more improvements were made to the implementation.

NVIDIA Looks To Have Some Sort Of Open-Source Driver Announcement For 2020

Start looking forward to March when NVIDIA looks to have some sort of open-source driver initiative to announce -- likely contributing more to Nouveau and we're crossing our fingers they will have sorted out the signed firmware situation to unblock those developers from delivering re-clocking support to yield better driver performance.

An Extensive Look At The AMD Naples vs. Rome Power Efficiency / Performance-Per-Watt

Since the AMD EPYC 7002 "Rome" series launch in August we have continue to be captivated by the raw performance of AMD's Zen 2 server processors across many different workloads as covered now in countless articles. The performance-per-dollar / TCO is also extremely competitive against Intel's Xeon Scalable line-up, but how is the power efficiency of these 7nm EPYC processors? We waited to deliver those numbers until having a retail Rome board for carrying out those tests and now after that and then several weeks of benchmarking, here is an extensive exploration of the AMD EPYC 7002 series power efficiency as well as a look at the peak clock frequencies being achieved in various workloads to also provide some performance-per-clock metrics compared to Naples.

Mesa Developers Weigh Renaming Gallium "State Tracker" To "API"

In addition to the discussion over potentially dropping non-Gallium3D drivers from Mesa or otherwise potentially forking a portion of the code, AMD's Marek Olšák made a separate proposal about renaming the Gallium3D "state tracker" concept to being "API" implementations.

Firefox 71 Linux Performance Isn't Looking All That Great

With each new release of Firefox we set out to see how the performance is looking on the Linux desktop. One discovery we've made is that when using Intel's Clear Linux the Firefox performance is a lot more competitive to Google Chrome than we traditionally see on Ubuntu Linux. But with Firefox 71 we're seeing the performance trending lower compared to Firefox 69 and 70.

NVIDIA GeForce GTX 1650 SUPER Linux Performance

For those looking to spend less than $200 USD on a graphics card, the recently launched NVIDIA GeForce GTX 1650 SUPER offers great value starting at $159 USD and working well with the NVIDIA Linux driver for providing decent 1080p Linux gaming performance as well as OpenCL / CUDA support. Here are benchmarks of the GTX 1650 SUPER alongside a total of 18 lower-end/mid-range AMD Radeon and NVIDIA GeForce graphics cards on Ubuntu Linux.

Mesa Devs Discuss Potentially Dropping Non-Gallium Drivers Or Forking Code For Gallium

Longtime open-source AMD graphics driver developer Marek Olšák has kicked off a discussion over the possibility in the not too distant future of either dropping non-Gallium3D drivers from Mesa (and moving them off to a maintenance branch or the like) or forking some of Mesa's existing code to allow it to be better optimized for Gallium3D use-cases. Due to raised concerns, other possibilities are also being expressed like simply moving ahead with optimizing the Mesa code-base for Gallium3D at a cost of potentially hitting dead code more often with the classic drivers.

Linux 5.5 Provides Knob To Toggle ASPM Link States Individually - Better Power-Savings

ASPM can be a big boost to help power-savings on Linux laptops and desktops as shown by a prominent kernel regression a number of years ago. However, a number of Linux drivers are forced to disable Active State Power Management (ASPM) due to quirky/buggy hardware where it ends up not being sane to enable that power-saving feature by default. But with the Linux 5.5 kernel is support for toggling ASPM link states via sysfs as an easy-to-perform manner for achieving better power-savings with friendly devices.
