This new command is a wrapper on top of perf record and perf report to
make it easier to configure for memory access profiling.
To record loads:
$ perf mem -t load rec .....
To record stores:
$ perf mem -t store rec .....
To get the report:
$ perf mem -t load rep

|
|
perf-mem - Profile memory accesses
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'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.
|
|
|
|

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,
