IBM Clarifies Stance On Developers Working On Open-Source Projects In Off-Hours

Earlier this week was a surprising Linux kernel networking commit that removed an IBM engineer as one of the driver maintainers for the IBM Power SR-IOV Virtual NIC driver. Seemingly at issue with this VNIC driver work was the developer using his personal email address in working on the driver in his off-hours. IBM has now clarified their stance on such work…

Linux's P-State Performance Governor Shows Unexpectedly Big Boosts For The Intel Core i9-11900K

The P-State and CPUFreq “performance” governors on Linux with desktop Intel/AMD processors can be of help for gaming and other select workloads by tending to keep the CPU clock frequencies higher than the default ondemand (CPUFreq) or powersave (P-State) governors used by nearly all Linux distributions. But with Intel’s new Core i9 11900K “Rocket Lake” is a dramatic difference in power and performance between the Intel P-State performance and powersave governors than what we have seen over the years with prior generations of Intel Core processors.

Ubuntu 21.04 Server Performance Offering Nice Gains For AMD EPYC 7003 Series

Tomorrow’s release of Ubuntu 21.04 is exciting on the desktop for Wayland by default in supported configurations and many other package updates and enhancements. But even for being a non-LTS release if you are interested in running Ubuntu Server there are some performance improvements to enjoy with newer platforms. Here is a look at the AMD EPYC 7003 “Milan” performance across Ubuntu 20.04 LTS, 20.10, and 21.04 with an AMD EPYC 7763 Supermicro server.
