KFunc scx_bpf_cpuperf_cur
This function queries the current relative performance of a CPU.
Definition
The current performance level of a CPU in relation to the maximum performance available in the system can be calculated as follows:
scx_bpf_cpuperf_cap() * scx_bpf_cpuperf_cur() / SCX_CPUPERF_ONE
The result is in the range [1, SCX_CPUPERF_ONE].
cpu: CPU of interest
Returns
The current relative performance of cpu in relation to its maximum. The return value is in the range [1, SCX_CPUPERF_ONE].
Signature
