With my recent AMD EPYC 9005 1P 4U server build using a Supermicro H13SSL-N motherboard, SilverStone kindly sent over their two Socket SP5 cooling options for AMD EPYC processors: the XE04-SP5 4U-compatible heatsink fan and then the XE360-SP5 AIO liquid cooler with a triple 120mm fan radiator to allow effectively cooling up to the new 400~500 Watt EPYC Turin processors. Here is a look at these two high-end AMD EPYC cooling options for those carrying out 4U EPYC 9004/9005 server builds along with thermal and performance benchmark results.

The FUSE feature enhancements were submitted today for the Linux 6.13 kernel as part of improving the file-system in user-space capabilities...

Huawei engineer Zhang Yi posted a set of nine patches today for enabling large folio support for regular files with the EXT4 file-system. These patches enable large folios for EXT4 on regular files except when using FSVERITY, FSCRYPT, or the journaled data mode. Long story short, these large folio patches can deliver some nice performance gains for both reads and writes...

Sent out last night for the ongoing Linux 6.13 merge window were all of the perf tool changes for the wonderful "perf" subsystem for performance profiling and the like. In addition to adding the HWMON PMU to "perf stat", leader sampling for inherited task events, and various other tooling improvements, there are also vendor event updates. Most notable with the updated CPU vendor events are new AMD Zen 5 processor events...

Richard Hughes of Red Hat has released Fwupd 2.0.2 as the newest update to this open-source firmware updating solution for Linux systems...

While the end of year holidays are fast approaching, my commitment to Linux hardware and open-source software remains and there still is a lot of interesting content to come this year still -- each and every day, without change for roughly a decade. Unfortunately though due to the (sad) state of the ad industry, many major companies focusing on the likes of Facebook/Meta ads, and the frequent use of ad-blockers by Linux/FLOSS readers make ongoing operations increasingly difficult. But if you'd like to show some love this holiday season, the Phoronix Premium "Cyber Week" / "Black Friday" special is now taking place so you can enjoy the site ad-free, native dark mode support, multi-page articles on a single page, and other benefits while hopefully allowing the site to continue for years to come...

The AMDXDNA kernel driver for Linux systems that was made open-source in January for supporting the Ryzen AI NPU on laptop SoCs going back to the Ryzen 7040 "Phoenix" series is now one step away from appearing in the mainline Linux kernel in the near future...

Earlier this week was the main power management updates for Linux 6.13 that included switching AMD EPYC Turin to using the amd_pstate driver on supported systems. Sent out this weekend was another set of power management updates that also includes a notable addition: the virtual CPUFreq driver...

Following all of the MM patches earlier this week sent in by Andrew Morton, on Sunday morning he sent out all of the non-MM patches that he manages for the Linux kernel. Notable for Linux 6.13 with this pull request is presenting the hung task counter as well as finishing off the folio conversion in the NILFS2 code...

Ahead of FreeBSD 14.2 hopefully releasing in just over one week, FreeBSD 14.2-RC1 is out this weekend as the last planned development release for testing ahead of that much anticipated point release...

A Microsoft Research project that was quietly announced a few years ago to some fanfare but not hearing much about since has been Demikernel as their library OS architecture for kernel-bypass I/O. A Phoronix reader brought up Demikernel this week and while it hasn't been talked about much in recent years it does remain under active development with the most recent commits as of hours ago...

IBM isn't formally releasing Power11 processors until next year, but their software engineers continue being quite busy preparing the Linux kernel and other open-source software for Power11. The newest on the kernel side is enabling support for KVM nested guests on IBM Power11 platforms...
