поддержка Intel Processor Trace в инструментах perf (Support for Intel Processor Trace within perf tools)
PEBS VIA INTEL PT
Some hardware has the feature to redirect PEBS records to the
Intel PT trace. Recording is selected by using the aux-output
config term e.g.
perf record -c 10000 -e '{intel_pt/branch=0/,cycles/aux-output/ppp}' uname
Note that currently, software only supports redirecting at most
one PEBS event.
To display PEBS events from the Intel PT trace, use the itrace o
option e.g.
perf script --itrace=oe
