[$] READ_ONCE(), WRITE_ONCE(), but not for Rust

The READ_ONCE() and WRITE_ONCE() macros are heavily used
within the kernel; there are nearly 8,000 call sites for
READ_ONCE(). They are key to the implementation of many lockless algorithms and can be necessary for some
types of device-memory access. So one might think that, as the
amount of Rust code in the kernel increases, there would be a place for
Rust versions of these macros as well. The truth of the matter, though, is
that the Rust community seems to want to take a different approach to
concurrent data access.

Qualcomm Sends Out Linux Patches For RAS Support On RISC-V For Reporting Hardware Errors

The latest work by Qualcomm on the RISC-V CPU architecture is sending out their first non-RFC patch series for enabling Reliability, Availability and Serviceability (RAS) support by making use of the RISC-V RERI specification. This RISC-V RAS support is useful for conveying hardware errors to users and will be especially important with future RISC-V Linux servers…

Linux 6.18 LTS vs. Liquorix Kernel On AMD Ryzen Threadripper Workstation Performance

It’s been a while since running benchmarks of the Liquorix kernel as an enthusiast-tailored downstream version of the Linux kernel focused on responsiveness for gaming, audio/video production, and other creator/enthusiast workloads. In today’s article is a look at how the latest Liquorix kernel derived from Linux 6.18 is competing against the upstream Linux 6.18 LTS kernel on the same system.

[$] SFC v. VIZIO: who can enforce the GPL?

The

Software Freedom Conservancy
(SFC) is

suing


VIZIO
over smart TVs that
include software licensed under the GPL and LGPL (including the Linux kernel,
FFmpeg, systemd, and others).
VIZIO didn’t provide the source code along with the device, and on request they
only provided some of it. Unlike a typical lawsuit about enforcing the GPL, the
SFC isn’t suing as a copyright holder; it’s suing as
a normal owner of the TV
in question. This approach opens some important legal questions, and after years
of pre-trial maneuvering (most recently resulting in
a ruling related to signing keys that
is the subject of a separate article),
we might finally obtain some answers when the case goes
to trial on January 12. As things stand, it seems likely that the judge in
the case will rule that that the GPL-enforcement lawsuits can be a matter of
contract law, not just copyright law, which would be a major change to how GPL
enforcement works.
