The irq command.

positional arguments:
<path/to/trace>
trace path

optional arguments:
-h, --help
show this help message and exit

-r REFRESH, --refresh REFRESH
Refresh period, with optional units suffix (default units: s)

--gmt Manipulate timestamps based on GMT instead of local time

--skip-validation
Skip the trace validation

--begin BEGIN
start time: hh:mm:ss[.nnnnnnnnn]

--end END
end time: hh:mm:ss[.nnnnnnnnn]

--period-begin PERIOD_BEGIN
Analysis period start marker event name

--period-end PERIOD_END
Analysis period end marker event name (requires --period-begin)

--period-begin-key PERIOD_BEGIN_KEY
Optional, list of event field names used to match period markers (default: cpu_id)

--period-end-key PERIOD_END_KEY
Optional, list of event field names used to match period marker. If none specified,
use the same --period-begin-key

--period-key-value PERIOD_KEY_VALUE
Optional, define a fixed key value to which a period must correspond to be
considered.

--cpu CPU
Filter the results only for this list of CPU IDs

--timerange TIMERANGE
time range: [begin,end]

-V, --version
show program's version number and exit

--metadata
Show analysis's metadata

--min MIN
Filter out durations shorter than min usec

--max MAX
Filter out durations longer than max usec

--freq Output the frequency distribution of handler durations

--freq-resolution FREQ_RESOLUTION
Frequency distribution resolution (default 20)

--freq-uniform
Use a uniform resolution across distributions

--freq-series
Consolidate frequency distribution histogram as a single one

--log Output the IRQs in chronological order

--stats
Output IRQ statistics

--irq IRQ
Output results only for the list of IRQ

--softirq SOFTIRQ
Output results only for the list of SoftIRQ
