AMD Posts New “AMD-PSTATE” CPUFreq Driver Leveraging CPPC For Better Perf-Per-Watt

At last! AMD has posted the Linux kernel driver patches for their new “AMD-PSTATE” driver! This driver with modern AMD Zen CPUs (initially limited to Zen 3) to achieve greater performance per Watt / power efficiency on Linux than the conventional ACPI CPUFreq driver.
The new AMD-PSTATE driver is akin to Intel’s P-State driver long used by Intel CPUs as better catering to their hardware than the generic ACPI CPUFreq driver. AMD-PSTATE leverages ACPI Collaborative Processor Performance Controls (CPPC) […] Continue Reading…

Not All Of The IBM POWER10 Firmware Is Currently Open-Source

Power E1080 server as their first in a new family of servers based on the IBM POWER10 processor. Sadly though not all of the POWER10 firmware is open-source.
While POWER9 was big for open-source fans with the formation of the OpenPOWER Foundation and Raptor Computing Systems designing POWER9-based systems that are fully open-source down to schematics and the motherboard firmware, the same can’t be currently said about POWER10. Raptor Computing Systems previously hinted that it might not be all rosy […] Continue Reading…

What Net Admins Must Know about NicheStack Vulnerabilities


At a time when cybersecurity attacks are swiftly increasing in volume, velocity, complexity, and potential impact, organizations managing critical operational technology (OT) – those which run massive energy grids, fuel lines, supply chains, transportation systems, factories, hospitals, and telecommunications networks – have emerged as a primary target. In fact, nine out of ten organizations reported in 2020 that they experienced an OT system intrusion within the past year, up from one out of five in 2019. In recent […] Continue Reading…
