There was the same problem that scaling_max_freq showed a limit,
but one did not know whether it comes from:
- thermal
- PPC/BIOS
restrictions.
This got solved by introducing:
/sys/.../cpuX/cpufreq/bios_limit
which shows the PPC limitation
A file:
/sys/.../cpuX/cpufreq/input_boost_limit
could show the currently raised min_freq, caused by
the input booster.
