Get Boost Clock programatically on Linux

So Ryzen Master for Windows shows the max boost clock of the current cpu.

I wonder if it is obtained via a LUT that has the information for all Ryzen CPUs, or if there a register somewhere, where the cpu communicates it's capabilities.

For Intel CPU's you can 'cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq', but for AMD CPU's this only shows the base frequency.
