Earlier this year AMD announced the Ryzen Threadripper PRO 5000 WX series but initially was limited to Lenovo workstations. Earlier this summer it was then announced the Threadripper PRO 5000 WX series would be heading to more system integrators and then the DIY market. Well, finally, these Zen 3 Threadripper chips are heading out to the DYI market and today the review embargo lifts. AMD recently sent over a Ryzen Threadripper PRO 5965WX for my Linux testing at Phoronix and here is my initial review and performance benchmarks for this Zen 3 24-core / 48-thread HEDT chip.

SUSE had been one of the big supporters of ReiserFS two decades ago when it was using the ReiserFS file-system by default but that practice ended in 2006. While SUSE/openSUSE hasn't defaulted to ReiserFS for many years, it has remained an install-time option and retained support for mounting ReiserFS file-systems, but that practice is likely soon ending...

BUS1 started out as a Linux kernel IPC module following the failure of KDBUS and while there still are occasional commits to that out-of-tree BUS1 kernel module, the involved (Red Hat) developers have been primarily working on Dbus-Broker as the high performance, user-space D-Bus implementation that delivers greater speed and reliability over the reference D-Bus code. Now also popping up under the BUS1 umbrella is "r-linux" as a Rust-written, capability-based Linux runtime...

Now with Linux 6.0, OpenRISC is finally exposing PCI bus support...
