SYNOPSIS
       perf mem [<options>] (record [<command>] | report)

DESCRIPTION
       "perf mem -t <TYPE> record" runs a command and gathers memory operation data from it, into perf.data. Perf
       record options are accepted and are passed through.

       "perf mem -t <TYPE> report" displays the result. It invokes perf report with the right set of options to
       display a memory access profile.

           Any command you can specify in a shell.
