While Windows gamers seem mixed over the AMD Ryzen 9000 series processors, for creator, scientific / HPC, code development, and many other technical computing areas I remain very impressed by the Ryzen 9000 (Zen 5) series desktop processors more than one month into constant testing with these Granite Ridge chips. One of the areas I hadn't explored until now but made me curious given the mixed messaging around gaming was how well workstation graphics workloads were performing with the new processors. For this brief weekend article is a look at the workstation graphics performance between the Ryzen 9 9950X and former Ryzen 9 7950X/7950X3D processors.

The work written about earlier this year on New Intel Linux Patches Continue Working To Improve Hybrid CPU Task Placement looks like it will be merged for the upcoming Linux 6.12 cycle as the patches have now been queued into the power management subsystem's "-next" branch. This latest Intel Core hybrid handling work is particularly focused on hybrid P/E-core processors without SMT / Hyper Threading, such as found with the upcoming Core Ultra 200V "Lunar Lake" processors...

OpenBMC as the Linux Foundation project backed by vendors like Intel / Microsoft / Google / Meta for an open-source BMC firmware stack continues to be a growing success. This alternative to long-used proprietary BMC software stacks continues to grow in popularity with AMD now using it on their reference motherboards and Supermicro being another notable user with some of their server platforms. Not entirely new but been meaning to write about it and NVIDIA talked more openly about it this week: NVIDIA is also a big supporter and user of OpenBMC for their high-end AI/HPC servers and BlueField DPU hardware...

While RISC-V processors don't need to worry about Meltdown and Spectre or have any other severe CPU vulnerabilities at the moment, with the upcoming Linux 6.12 kernel the RISC-V code is set to enable the generic CPU vulnerabilities support...

Merged three years ago in Linux 5.12 was IDMAPPED mounts for new use-cases from containers to systemd-homed. IDMAPPED mounts allow for different mounts to expose the same file or directory with different ownership such as for sharing files between multiple users or multiple systems. With time all of the major Linux file-systems have seen support added for IDMAPPED mounts while for Linux 6.12 support is on the way for FUSE file-systems...

Intel has submitted more kernel graphics driver changes for the upcoming Linux 6.12 cycle. Following the pull requests to DRM-Next last week to enable Lunar Lake Xe2 graphics and Battlemage by default, some more lingering feature patches were merged today. Most exciting with this last round of patches before Linux 6.12? Intel graphics card fan speed reporting is finally wired up for their Linux driver...

One of the security changes with AMD Zen 5 processors that I haven't seen AMD publicly mention at least not prominently is that the new cores are not vulnerable to Speculative Return Stack Overflow (SRSO). Unlike Zen 4 and prior, under Linux I noticed that Zen 5 is no longer affected by the SRSO "INCEPTION" vulnerability. But of course there does remain other CPU security mitigations in place carried over from Zen 4. For those wondering about the mitigation costs or if it's worthwhile running Zen 5 with the "mitigations=off" insane mode, here are some benchmarks.

Back in 2022 were a set of patches that allowed compiling the ARM64 Linux kernel from Apple macOS hosts. The intent was for developers just wanting to do some build/smoke testing from under an Apple Silicon device running macOS to see at least any kernel changes are successfully compiling on macOS with its LLVM/Clang-based toolchain. An updated form of those patches were posted today for review...

With this week's announcement of the Intel Core Ultra 200V Series "Lunar Lake" processors, I've been very eager to try out the Meteor Lake successor for Linux testing. As sadly is usually the case, for delivering Linux support details and performance benchmarks around launch-time I'm typically left buying a laptop retail for Linux testing. In this case after seeing the Lunar Lake laptops announced this week and their availability, I ended up settling on the ASUS Zenbook S 14 (UX5406SA-S14.U71TB) for the initial Core Ultra 200V series Linux review...

We're very close to the finish line for the mainline Linux kernel being able to enable real-time "PREEMPT_RT" kernel support...

Sent out today were the DRM fixes for 6.11-rc7 ahead of the Linux 6.11-rc7 kernel being released on Sunday.

Weston 14.0 was released today as the newest feature release for this reference Wayland compositor...

When it comes to the Rust programming language support within the Linux kernel one of the limitations is that the CPU architecture support isn't as widespread. Currently Rust for Linux supports x86_64, AArch64 (ARM64) little-endian, LoongArch, and RISC-V. While those cover the main targets, POWER is notably missing and many other niche CPU architectures supported by the Linux kernel especially for aging platforms. Patches posted today to the Linux kernel mailing list would extend the Rust support to MIPS...

Google announced today that the Android 15 source code has been released to the Android Open-Source Project (AOSP)...

While there are more than 74k packages available within Debian's package management system for x86_64 systems, not all of the packages are well maintained and a portion of them haven't seen any maintenance/updates in ages. Debian developers have recently begun discussing how to begin removing more of those long unmaintained packages from the archive...
