| perf-mem - Profile memory accesses |
| 'perf mem' [<options>] (record [<command>] | report) |
| "perf mem 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 report" displays the result. It invokes perf report with the |
| right set of options to display a memory access profile. By default, loads |
| and stores are sampled. Use the -t option to limit to loads or stores. |
| Note that on Intel systems the memory latency reported is the use-latency, |
| not the pure load (or store latency). Use latency includes any pipeline |
| queueing delays in addition to the memory subsystem latency. |
| Any command you can specify in a shell. |
| Select the memory operation type: load or store (default: load,store) |
| Dump the raw decoded samples on the screen in a format that is easy to parse with |
| Specify the field separator used when dump raw samples (-D option). By default, |
| The separator is the space character. |
| 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 |
