While Simultaneous Multi-Threading (SMT) on Intel/AMD x86_64 processors is limited to providing one additional thread per core, SMT on IBM POWER hardware can provide 4-way and even 8-way SMT for some processor models. With Linux 6.6 the /sys/devices/system/cpu/smt/control interface is being extended to allow greater control over managing partial SMT states in cases of the CPUs supporting more than 2-way SMT at Linux run-time...

Moving forward Canonical is aiming for a new "4/2" week cycle for kernel SRUs...

Linux's cpupower utility lives within the Linux kernel source tree for reading and tuning various CPU power settings rather than poking at sysfs files directly or other means of adjusting your processor power-related tunables. With the upcoming Linux 6.6 kernel cycle the cpupower utility is adding support for adjusting new AMD P-State driver features...

The new AMD EPYC Bergamo and Genoa-X processors have been very fascinating in the lab from the performance angle and the many different features and knobs provided by these new high-end server processors focused on dense cloud and energy-efficient deployments and HPC/AI, respectively. With Bergamo the flagship AMD EPYC 9754 provides 128 cores with SMT and the Zen 4C cores still boast AVX-512. Another nifty aspect on this high core count CPU catering to cloud service providers is the adjustable TDP from 320 to Watts. Prior Phoronix benchmarks have looked at the default 360 Watt performance and the 400W at the high-end with power determinism mode while today's article is looking at the efficiency gains made possible by pulling back to a 320W cTDP.
