Did you build just the module or the whole haiku.hpkg?

Just the module.

I patched function `is_cpu_model_supported` for my cpu. Now syslog has
these lines:
{{{
KERN: using Intel P-States: min 8, max 15, boost 23
KERN: found cpufreq module: power/cpufreq/intel_pstates/v1
KERN: using Intel C-States: C0, C1, C3, C4, C5, C6, C7
KERN: found cpuidle module: power/cpuidle/intel_cstates/v1
}}}
But all bench testing witch chess engines still shows the same low
results.
It seems, you are right with #16517. Other p-states are never activated
and the cpu remains at it’s default clock 1.5ghz (p-state 15).
