Phoronix

With New Year's Eve at Phoronix it means combing through Git statistics for the past year of various open-source projects among other end of year coverage... The most surprising takeaway from today's end of year exploration was seeing the Linux kernel hitting a decade low for the number of new commits this year. But not all is bad as on a line count the annual metric is comparable to more recent years...

One of the unexpected twists this year was after several years of AMD quietly funding the ZLUDA developer for enabling unmodified CUDA applications to run on AMD GPUs at near-native performance, the ZLUDA atop AMD HIP code was made available and open-source following the end of the AMD contract. But then later on that ZLUDA code was taken down at the request of AMD. Back in October ZLUDA then decided to pursue a new life as an open-source multi-GPU CUDA implementation with an emphasis on AI workloads. Now as a New Year's Eve surprise, ZLUDA v4 was released as the first step to that new codebase...

The holiday between Christmas and New Year's is... Linus Torvalds' birthday on 28 December. Capping off the Linux creator's 55th birthday week is the Linux 6.13-rc5 kernel release...

Last weekend a Meta engineer posted Linux kernel patches to make use of the AMD INVLPGB instruction for broadcast TLB invalidation. The Linux kernel can in turn invalidate TLB entries on remote CPUs without needing to send IPIs and without having to wait for remote CPUs to handle those interrupts. Synthetic benchmarks shown in that patch series were very promising and thus I carried out some benchmarking over the holidays of this AMD INVLPGB support for the Linux kernel.

Following the benchmarks earlier this month looking at the Red Hat Enterprise Linux 10 beta performance as well as the AlmaLinux 10 beta, on the same AMD EPYC server here are benchmarks when adding in CentOS Stream 10 to the mix. CentOS Stream 10 as the upstream to Red Hat Enterprise Linux 10 is largely similar to what's found in the RHEL 10.0 beta but one of the key differences is being powered by Linux 6.12 LTS rather than Linux 6.11 as currently used by the AlmaLinux/RHEL 10 beta. Here is how the performance of CentOS Stream 10 is looking in comparison on the same hardware.

AMD's new products this year have not only been supported well on the server side with their new EPYC 9005 "Turin" processors but also on the consumer side with the Ryzen AI 300 series laptop and Ryzen 9000 series desktop Zen 5 processors.

From the software side 2024 was great for GNOME while over on the GNOME Foundation side they had to deal with coping from running a recent deficit and also their executive director departing after less than one year...

Linux 6.13 is introducing a new Lazy Preemption mode with the "PREEMPT_LAZY" option. The lazy preemption mode is similar to full preemption but is less eager to preempt normal (SCHED_NORMAL) tasks. The goal is on reducing lock holder preemption and obtaining some of the performance gains found under the voluntary preemption mode. For Linux 6.13 the lazy preemption mode was exposed for x86/x86_64, RISC-V, and later added for LoongArch. Likely with the upcoming Linux 6.14, lazy preempt should work on POWER platforms...
