´perf script´ to see a detailed trace of the workload that was
recorded.

You can also run a set of pre-canned scripts that aggregate and
summarize the raw trace data in various ways (the list of scripts is
available via ´perf script -l´).  The following variants allow you to
record and run those scripts:

´perf script record <script> <command>´ to record the events required
for ´perf script report´.  <script> is the name displayed in the
output of ´perf script --list´ i.e. the actual script name minus any
language extension.  If <command> is not specified, the events are
recorded using the -a (system-wide) ´perf record´ option.

´perf script report <script> [args]´ to run and display the results
of <script>.  <script> is the name displayed in the output of ´perf
trace --list´ i.e. the actual script name minus any language
extension.  The perf.data output from a previous run of ´perf script
record <script>´ is used and should be present for this command to
succeed.  [args] refers to the (mainly optional) args expected by
the script.

´perf script <script> <required-script-args> <command>´ to both
record the events required for <script> and to run the <script>
using ´live-mode´ i.e. without writing anything to disk.  <script>
is the name displayed in the output of ´perf script --list´ i.e. the
actual script name minus any language extension.  If <command> is
not specified, the events are recorded using the -a (system-wide)
´perf record´ option.  If <script> has any required args, they
should be specified before <command>.  This mode doesn´t allow for
optional script args to be specified; if optional script args are
desired, they can be specified using separate ´perf script record´
and ´perf script report´ commands, with the stdout of the record step
piped to the stdin of the report script, using the ´-o -´ and ´-i -´
options of the corresponding commands.

´perf script <top-script>´ to both record the events required for
<top-script> and to run the <top-script> using ´live-mode´
i.e. without writing anything to disk.  <top-script> is the name
displayed in the output of ´perf script --list´ i.e. the actual
script name minus any language extension; a <top-script> is defined
as any script name ending with the string ´top´.

[<record-options>] can be passed to the record steps of ´perf script
record´ and ´live-mode´ variants; this isn´t possible however for
<top-script> ´live-mode´ or ´perf script report´ variants.

See the ´SEE ALSO´ section for links to language-specific
information on how to write and run your own trace scripts.

Any command you can specify in a shell.

Display verbose dump of the trace data.

Show latency attributes (irqs/preemption disabled, etc).

Display a list of available trace scripts.

Process trace data with the given script ([lang]:script[.ext]). If the string lang is specified in place of a script name, a list of supported languages will be displayed instead.

Generate perf-script.[ext] starter script for given language, using current perf.data.

Force system-wide collection. Scripts run without a <command> normally use -a by default, while scripts run with a <command> normally don’t - this option allows the latter to be run in system-wide mode.

Input file name. (default: perf.data unless stdin is a fifo)

Do various checks like samples ordering and lost events.

Comma separated list of fields to print. Options are: comm, tid, pid, time, cpu, event, trace, ip, sym, dso, addr, symoff, srcline, period. Field list can be prepended with the type, trace, sw or hw, to indicate to which event type the field list applies. e.g., -f sw:comm,tid,time,ip,sym and -f trace:time,cpu,trace

vmlinux pathname

kallsyms pathname

Look for files with symbols relative to this directory.

When printing symbols do not display call chain.

Only report samples for the list of CPUs provided. Multiple CPUs can be provided as a comma-separated list with no space: 0,1. Ranges of CPUs are specified with -: 0-2. Default is to report samples on all CPUs.

Only display events for these comms. CSV that understands file://filename entries.

Only show events for given process ID (comma separated list).

Only show events for given thread ID (comma separated list).

Display extended information about the perf.data file. This adds information which may be very large and thus may clutter the display. It currently includes: cpu and numa topology of the host system. It can only be used with the perf script report mode.

Try to resolve the path of [kernel.kallsyms]
