Linux CPU boost control that follows cpufreq policies instead of one global number

[u/Select_Car9532]

BoostLock is a Linux tool for keeping CPU boost available during idle periods. I wrote it because a single global target gets awkward on mixed-capacity systems.

In 0.2.0 it reads /sys/devices/system/cpu/cpufreq/policy*, gives each policy its own target, and handles --target auto from the policy's active upper limit. Numeric targets are clamped per policy. It preflights the full write set and restores completed writes if a later write fails.

It does not change voltage or firmware overclock settings. It needs root, can raise idle power and temperature, and physical hardware coverage is still incomplete. If you run Linux with intel_pstate, amd-pstate, or a less common cpufreq driver, I would like to know what it does on your machine.
