To represent software control flow, "branches" samples are produced. By default
a branch sample is synthesized for every single branch. To get an idea what
-data is available you can use the 'perf script' tool with no parameters, which
-will list all the samples.
+data is available you can use the 'perf script' tool with all itrace sampling
+options, which will list all the samples.
perf record -e intel_pt//u ls
- perf script
+ perf script --itrace=ibxwpe
An interesting field that is not printed by default is 'flags' which can be
displayed as follows:
- perf script -Fcomm,tid,pid,time,cpu,event,trace,ip,sym,dso,addr,symoff,flags
+ perf script --itrace=ibxwpe -F+flags
The flags are "bcrosyiABEx" which stand for branch, call, return, conditional,
system, asynchronous, interrupt, transaction abort, trace begin, trace end, and
which, in turn, is the same as
- --itrace=ibxwpe
+ --itrace=cepwx
The letters are:
--show-round-events
Display finished round events i.e. events of type PERF_RECORD_FINISHED_ROUND.
+--show-bpf-events
+ Display bpf events i.e. events of type PERF_RECORD_KSYMBOL and PERF_RECORD_BPF_EVENT.
+
--demangle::
Demangle symbol names to human readable form. It's enabled by default,
disable with --no-demangle.
The number of threads to run when synthesizing events for existing processes.
By default, the number of threads equals to the number of online CPUs.
+--namespaces::
+ Record events of type PERF_RECORD_NAMESPACES and display it with the
+ 'cgroup_id' sort key.
