NAME

       perf-mem - Profile memory accesses

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.

OPTIONS

       <command>...
           Any command you can specify in a shell.

       -t, --type=
           Select the memory operation type: load or store (default: load)

       -D, --dump-raw-samples=
           Dump the raw decoded samples on the screen in a format that is easy to parse with one
           sample per line.

       -x, --field-separator
           Specify the field separator used when dump raw samples (-D option). By default, The
           separator is the space character.

       -C, --cpu-list
           Restrict dump of raw samples to those provided via this option. Note that the same
           option can be passed in record mode. It will be interpreted the same way as perf
           record.
