Contemporary AMD processors have a frequency boost feature, called "Precision Boost". Sadly, the Linux kernel driver configuration as of Ubuntu Jammy + Linux 6.5 does not expose boost control. Some user land control does appear to be promised for future kernels.
In the mean time, this patch permits benchmark experiments to run, but prints a console warning that results may be noisy.
