AMD Linux engineers have introduced a new perf tool called "schedstat" that aims to be less resource intensive and convenient than the existing "perf sched" tool for profiling kernel scheduler behavior.

With GCC 14 stable released and GCC 15 now in development on trunk, new feature code is landing for the GNU Compiler Collection. Among the early features is Microsoft contributing the "Windows on ARM64" target with aarch64-w64-mingw32. The start of the new cycle also brings code removal for features deprecated in prior cycles. Among the old code being cleared out in GCC 15 is saying goodbye to Oracle Solaris 11.3.

As noted recently, EROFS has been exploring Zstd compression support for this open-source read-only Linux file-system. Today the patch was posted for enabling Zstandard use.

Two different merges today for Mesa 24.2 are worth calling out for the open-source Linux graphics stack.

The GNOME Foundation today published their 2023 annual report that outlines their accomplishments as well as a look at the finances.

Microsoft engineers have contributed Windows On ARM64 support to the upstream GNU Compiler Collection (GCC) with the new "aarch64-w64-mingw32" target.

While rolling out the new iPad Pro tablets today, Apple announced the M4 as their newest in-house silicon design.

Red Hat Summit 2024 is underway in Denver, Colorado... Given the times, artificial intelligence (AI) is taking a heavy presence at the event with Red Hat announcing today RHEL AI.

The Raspberry Pi Foundation today announced the beta availability of Raspberry Pi Connect as a means of securely having remote GUI access to your Remote Pi from a web browser.

Vulkan 1.3.284 was published on Monday with only a few changes but bearing one notable new extension.

AMD engineers posted a new set of Linux driver patches on Tuesday that "addresses critical issues and enhances performance settings for CPUs with heterogeneous core types" while using the AMD P-State CPU frequency scaling driver.

In addition to approving -O3 optimized Python builds, the Fedora Engineering and Steering Committee (FESC)) this week unanimously approved a Fedora 41 change proposal for making RPM package builds more reproducible.

Over the past year there's been much work happening within the Linux kernel's sysctl code for clearing up ~64 bytes of bloat per array throughout the kernel by dropping the last sysctl "sentinel" entry at the end of each array. This also helps in reducing the build time of the kernel and is a nice improvement. With Linux 6.10, the sysctl sentinel clearing throughout different subsystems is set to happen.

For the past several months AMD Linux engineers have been working on AMD Core Performance Boost support for their P-State CPU frequency scaling driver. The ninth iteration of these patches were posted on Monday and besides the global enabling/disabling support for Core Performance Boost, it's now possible to selectively toggle the feature on a per-CPU core basis.

GCC 14.1 has been released today as the first stable compiler release in the GCC 14 series. GCC 14.1 brings one year worth of improvements to this open-source compiler from new CPU support and new ISA extensions to new C/C++ language features, static analyzer improvements, new AMD GPU support, and many other additions.

Back when looking at the AMD Ryzen 7000 series budget server performance last year, DDR5-4800 ECC UDIMMs were used with the ASRock Rack 1U4LW-B650/2L2T Ryzen server given that's what was broadly available at the time. Since then there's been more ECC UDIMMs coming to market above DDR5-4800 speeds. Recently I bought a pair of Kingston Server Premier 32GB 5600MT/s DDR5 ECC CL46 UDIMMs (KSM56E46BD8KM-32HA) and that's the focus of today's tests. For those curious if the faster ECC UDIMMs are worthwhile compared to the commonality of DDR5-4800 ECC UDIMMs, these benchmarks are for you.

Following last week's release of Red Hat Enterprise Linux 9.4 stable, the AlmaLinux crew today announced AlmaLinux 9.4.

In addition to Linux 6.10 expected to drop support for very old DEC Alpha processors (EV5 and earlier), it looks like the PowerPC 40x (early PowerPC 400 series) processor and platform support will be retired too.

The Fedora Engineering and Steering Committee (FESCo) has signed off on the plans for Fedora 41 to build its Python using the "-O3" compiler optimization level rather than the "-O2" default for Fedora packages in the name of better performance.

The Linux 6.10 kernel is poised to remove support for old DEC Alpha EV5 platforms and earlier.
