perf kwork top: Add -C/--cpu -i/--input -n/--name -s/--sort --time options
Provide the following options for perf kwork top:
1. -C, --cpu <cpu> list of cpus to profile
2. -i, --input <file> input file name
3. -n, --name <name> event name to profile
4. -s, --sort <key[,key2...]> sort by key(s): rate, runtime, tid
5. --time <str> Time span for analysis (start,stop)
Example usage:
# perf kwork top -h
Usage: perf kwork top [<options>]
-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)
# perf kwork top -C 2,4,5

OPTIONS for 'perf kwork top'
|
||||
---------------------------------
|
||||
|

-C::
|
||||
--cpu::
|

Only show events for the given CPU(s) (comma separated list).

-i::
|
||||
--input::
|
||||
Input file name. (default: perf.data unless stdin is a fifo)
|
||||
|
||||
-n::
|
||||
--name::
|
||||
Only show events for the given name.
|
||||
|
||||
-s::
|
||||
--sort::
|
||||
Sort by key(s): rate, runtime, tid
|
||||
|
||||
--time::
|
||||
Only analyze samples within given time window: <start>,<stop>. Times
|
||||
have the format seconds.microseconds. If start is not given (i.e., time
|
||||
string is ',x.y') then analysis starts at the beginning of the file. If
|
||||
stop time is not given (i.e, time string is 'x.y,') then analysis goes
|
