Phoronix: Per-Policy CPU Performance Boosting Proposed For Linux

For processors supporting CPU performance boosting with higher performance states available beyond the base states, Linux allows toggling the boosting on a per-CPU basis. However, a new patch proposed this week would allow per-policy performance boosting where capable...

Seems to me that the scheduler would be in the best position to control this. Basically, you'd set a task to low latency/high throughput, then it could make sure all cores running that task have frequency boosting enabled, cores for execution could be selected in order to maximize probability that they actually can boost the frequency depending on CPU limitations, trade offs regarding memory access, cache locality, energy consumption etc could be factored in.
