Merged last month to the GNU C Library (glibc) Git code was a new tunable for non-temporal stores for memset. This optimization for glibc's memset performance was limited to Intel processors given at the time it was only tested/benchmarked on Intel CPUs but now it's proven to be useful too for AMD processors...

While last year we saw Fedora to no longer omit the frame pointer to help in debugging/profiling Fedora packages and Ubuntu 24.04 LTS also enabled frame pointers for better debugging/profiling, among other distributions, there is the known performance implications of no longer omitting the frame pointer. But now in aiming to make the best of both worlds, it turns out Red Hat has been developing eu-stracktrace as a new means of profiling without relying on frame pointers...

Last month AMD Linux engineers posted ap atch series for better handling heterogeneous core type CPUs.

Announced today is that the UXL Foundation has begun collaborating with The Khronos Group...

Covered last week on Phoronix was a new patch from Intel that with tuning to the P-State CPU frequency scaling driver was showing big wins for Intel Core Ultra "Meteor Lake" performance and power efficiency. I was curious with the Intel claims posted for a couple benchmarks and thus over the weekend set out to run many Intel Meteor Lake benchmarks on this one-line kernel patch... The results are great for boosting the Linux performance of Intel Core ultra laptops with as much as 72% better performance.

With the AMD EPYC 4004 series that was announced in May and we have delivered benchmarks of the entire EPYC 4004 stack from the 4-core SKU up through the 16-core model with 3D V-Cache, there are many advantages over Intel's Xeon E-2400 series competition. In addition to going up to 16 cores versus 8 with the Xeon E-2400 series, the more competitive pricing, the 3D V-Cache SKUs, and 28 PCIe lanes rather than 20, the AMD EPYC 4004 models also support DDR5-5200 memory where as the Intel Raptor Lake E-2400 models are bound to DDR5-4800. In this follow-up testing is a look at the AMD EPYC 4004 performance both at DDR5-4800 and DDR5-5200 speeds for showing the performance difference.

With this week's Computex announcement by AMD of the Ryzen AI 300 series laptop processors built atop Zen 5, one of the pleasant aspects has been several laptop models being announced already to be powered by either the Ryzen AI 9 365 or Ryzen AI 9 HX 370 flagship models. Some models are also already available for pre-order ahead of launch day. This is quite nice compared to in the past there was often at times quite a delay between the initial AMD Ryzen mobile announcements and being able to (pre)order any hardware. And thus I've already been looking around to coordinate near launch day Linux testing of the new AMD Zen 5 powered Ryzen AI 300 series hardware...
