1 top reads some tick counters from /proc/stat
2 provided by the kernel and defined as
3
4 struct cpu_usage_stat {
5 cputime64_t user;
6 cputime64_t nice;
7 cputime64_t system;
8 cputime64_t softirq;
9 cputime64_t irq;
10 cputime64_t idle;
11 cputime64_t iowait;
12 cputime64_t steal;
13 };
14
15 in kernel_stat.h

17 You probably can guess the meaning better than I could:
18
19 # time spent waiting for IO to complete
20 wa=iowait
21
22 # time spent within hardware interrupt handlers
23 hi=irq

25 # time spent within other critical sections within the kernel
26 si=softirq
