perf kwork top: Implements BPF-based cpu usage statistics

Use BPF to collect statistics on the CPU usage based on perf BPF skeletons.

Example usage:

# perf kwork top -h

Usage: perf kwork top [<options>]

-b, --use-bpf Use BPF to measure task cpu usage
-C, --cpu <cpu> list of cpus to profile
-i, --input <file> input file name
-n, --name <name> event name to profile
-s, --sort <key[,key2...]>
sort by key(s): rate, runtime, tid
--time <str> Time span for analysis (start,stop)
