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.
