SMT Remains Very Advantageous For 5th Gen AMD EPYC Performance

([Processors] 6 February 10:50 AM EST 81 Comments)

After recently re-visiting the AMD EPYC 9005 series AVX-512 performance, I followed up with some fresh SMT benchmarks looking at the performance benefits and power of toggling Simultaneous Multi-Threading on the 5th Gen AMD EPYC "Turin" hardware. Here are some fresh numbers looking at the SMT performance with AMD Zen 5 server processors.



AMD Talks Up IREE/MLIR Programming For Ryzen AI NPUs

([AMD] 6 February 10:00 AM EST Ryzen AI NPU Programming)

While the AMDXDNA driver was merged for the Linux 6.14 kernel for enabling the Ryzen AI NPUs atop a mainline kernel build, there's still the user-space software needed for making use of the neural processing units found in Ryzen AI SoCs. AMD talked more about programming Ryzen AI NPUs last weekend in Belgium at the FOSDEM 2025 developer conference.

Mesa 25.0 Is Trending Well For Release Later This Month

([Mesa] 6 February 06:56 AM EST Mesa 25.0)

GNU Gold Linker Is Deprecated & Will Be Gone For Good Without New Developers

([GNU] 6 February 06:39 AM EST GNU Gold Linker)

With the recent GNU Binutils 2.44 release, one of the changes is worth calling out in its own article: the GNU Gold linker is now officially deprecated and is now being segregated to its own extra Binutils package but risks being removed all together without new developer volunteers stepping up to maintain this linker.



PipeWire Is Doing An Excellent Job Handling Audio/Video Streams On The Linux Desktop

([PipeWire] 6 February 06:24 AM EST PipeWire 2025)

Google Interested In The Modern Intel Xe Linux Kernel Driver On Alder Lake

([Intel] 5 February 08:40 PM EST Xe Driver Rather Than i915)

The modern Intel "Xe" Linux kernel Direct Rendering Manager (DRM) driver as the clean successor to the i915 driver has been an experimental option for Tigerlake and newer but only for Xe2 graphics (Lunar Lake / Battlemage) and newer is it used by default. But Google at least for their Chromebook use-cases is entertaining the idea of switching over to the Xe driver rather than the long-used i915 kernel driver for Alder Lake era hardware.



Bisecting The Linux 6.14 Performance Regression With System76 Thelio + AMD Threadripper

([Linux Kernel] 5 February 04:30 PM EST Power Management Woes)

Yesterday I showcased Linux 6.14 Git performance worse than Linux 6.13 and 6.12 in a number of multi-threaded workloads. Due to that initial discover being on the lone AMD EPYC Turin 2P server that is always busy running through new benchmarks for future content as well as I am being persistently short on time and constantly under pressure due to the state of the web/ad industry, I didn't expect to get around to digging deeper into the problem in the near-term. But as I ended up being able to reproduce some of the regressions on a System76 Thelio Major workstation at my desk with the still mighty powerful Ryzen Threadripper 7980X, I was able to turn around a quick bisect.



NVIDIA Engineer Talks Up sched_ext Linux Scheduler Possibilities At FOSDEM

([NVIDIA] 5 February 02:00 PM EST sched_ext)

Merged last year for the Linux 6.12 kernel was sched_ext for allowing extensible scheduler possibilities by allowing schedulers to be implemented as eBPF code and dynamically loaded into the kernel. This allows for rapidly developing new schedulers as well as exploring other new possibilities around more intelligent kernel scheduling decisions. Meta, Google, Canonical (Ubuntu), and others have been big proponents of sched_ext and NVIDIA is also increasingly vocalizing their support for these extensible scheduler opportunities.

AMD Broadcast TLB Invalidation Patches For Linux Updated, Intel RAR Eyed Next

([AMD] 5 February 10:29 AM EST AMD INVLPGB)

One of the set of patches for the Linux kernel that we have been looking forward to but that wasn't wrapped up in time for the recent Linux v6.14 merge window was the work enabling use of the AMD INVLPGB instruction on Zen 3 CPUs and newer for broadcast TLB invalidation. This can lead to a nice performance bump in some workloads while the eighth iteration of those patches were posted overnight.
