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

      news.movim.eu / Phoronix • 6 February, 2025

    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

      news.movim.eu / Phoronix • 5 February, 2025

    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

      news.movim.eu / Phoronix • 5 February, 2025

    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

      news.movim.eu / Phoronix • 5 February, 2025

    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...
