Current perf report/script/... have a --time option to limit the time
range of output. But right now it only supports absolute time, add
support for time percentage.
For example:
1. Select the second 10% time slice
perf report --time 10%/2
2. Select from 0% to 10% time slice
perf report --time 0%-10%
It also support the multiple time ranges.
3. Select the first and second 10% time slices
perf report --time 10%/1,10%/2
4. Select from 0% to 10% and 30% to 40% slices
perf report --time 0%-10%,30%-40%
Changelog:
v4: An issue is found. Following passes.
perf script --time 10%/10x12321xsdfdasfdsafdsafdsa
Now it uses strtol to replace atoi.
Committer notes:
This just puts in place the infrastructure, so the examples in this cset
comment will only work later, after more patches in this series are
applied.
