Servo Announces Sponsorship Tiers To Get More Organizations Backing This Browser Engine

The Servo open-source web browser engine has been making good progress in recent times. Long outside the confines of Mozilla and working as a Linux Foundation Europe project, Servo has been advancing thanks to Igalia and other open-source developers while getting by on around ~$5.7k USD per month thanks mostly to donations from individuals. Servo has now announced sponsorship tiers in hopefully to solicit more donations from larger organizations…

OnLogic Refreshes Its CL Series With the New CL260 Edge Gateway

The CL260 is presented as an ultra-compact industrial edge gateway built around Intel N-Series processors. It is intended for deployments that require a small, durable, and headless controller operating within cabinet-mounted or space-restricted environments. The system offers configuration options for storage, wireless connectivity, and operating systems. The system uses either the Intel N150 or Intel […]

Canonical Gets Flutter Up And Running On RISC-V For Ubuntu

Canonical has been bullish on RISC-V with Ubuntu being one of the most common Linux distributions endorsed by RISC-V board vendors. Canonical also has been bullish on the Flutter toolkit for crafting their desktop installer UI and other modern UI/app interfaces. But these two together haven’t panned out with Flutter not currently supporting RISC-V. Canonical has submitted pull requests now for enabling RISC-V support with Flutter…

Updated Steam Runtime Switches To Debian 13 Libraries, SDL2 Using Compatibility Layer

An updated version of the Steam Linux Runtime 4 branch was rolled out that has now shifted from Debian 11 to Debian 13 libraries for some significant upgrades. In the process more libraries have gone x86_64 only in foregoing the i386 builds. In addition, the SDL 2 library support for the Steam Runtime is now provided by sdl2-compat as the compatibility layer for SDL2 atop SDL3…

Racing karts on a Rust GPU kernel driver (Collabora blog)

In July, Collabora announced
the Rust-based Tyr
GPU driver
for Arm Mali
GPUs. Daniel Almeida has posted an update
on progress with a prototype of the driver running on a Rock 5B board
with the Rockchip RK3588 system-on-chip:

The Tyr prototype has progressed from basic GPU job execution to
running GNOME, Weston, and full-screen 3D games like SuperTuxKart,
demonstrating a functional, high-performance Rust driver that matches
C-driver performance and paves the way for eventual upstream
integration! […]

Tyr is not ready to be used as a daily-driver, and it will still
take time to replicate this upstream, although it is now clear that we
will surely get there. And as a mere prototype, it has a lot of
shortcuts that we would not have in an upstream version, even though
it can run on top of an unmodified (i.e., upstream) version of
Mesa.

That said, this prototype can serve as an experimental driver and
as a testbed for all the Rust abstraction work taking place
upstream. It will let us experiment with different design decisions
and gather data on what truly contributes to the project’s
objective.

There is also a video on
YouTube of the prototype in action.

Linux 6.19 Slated To Land “mm/cid” Rewrite That Has Very Positive Performance Potential

A set of Linux kernel patches posted back in October for rewriting the kernel’s memory-mapped concurrency ID code for some nice performance wins looks like it will land for Linux 6.19. This is the code that prominent Intel engineer Thomas Gleixner found to yield up to an 18% improvement for the PostgreSQL database. My testing of this “mm/cid” code has also shown some nice performance wins too…

[$] BPF and io_uring, two different ways

BPF allows programs uploaded from user space to be run, safely, within the
kernel. The io_uring subsystem, too, can be thought of as a way of loading
programs in the kernel, though the programs in question are mostly a
sequence of I/O-related system calls. It has sometimes seemed inevitable
that io_uring would, like many other parts of the kernel, gain BPF
capabilities as a way of providing more flexibility to user space. That
has not yet happened, but there are currently two patches sets under
consideration that take different approaches to the problem.
