| SYNOPSIS |
| -------- |
| [verse] |
| 'perf report' [-i <file> | --input=file] |
| |
| DESCRIPTION |
| ----------- |
| This command displays the performance counter profile information recorded |
| via perf record. |
| |
| OPTIONS |
| ------- |
| -i:: |
| --input=:: |
| Input file name. (default: perf.data) |
| -d:: |
| --dsos=:: |
| Only consider symbols in these dsos. CSV that understands |
| file://filename entries. |
| -n:: |
| --show-nr-samples:: |
| Show the number of samples for each symbol |
| -T:: |
| --threads:: |
| Show per-thread event counters |
| -C:: |
| --comms=:: |
| Only consider symbols in these comms. CSV that understands |
| file://filename entries. |
| -S:: |
| --symbols=:: |
| Only consider these symbols. CSV that understands |
| file://filename entries. |
| |
| -s:: |
| --sort=:: |
| Sort by key(s): pid, comm, dso, symbol, parent. |
| |
| -w:: |
| --field-width=:: |
| Force each column width to the provided list, for large terminal |

| |
| -t:: |
| --field-separator=:: |
| |
| Use a special separator character and don't pad with spaces, replacing |
| all occurances of this separator in symbol names (and other output) |
| with a '.' character, that thus it's the only non valid separator. |
| |
| -g [type,min]:: |
| --call-graph:: |
| Display callchains using type and min percent threshold. |
| type can be either: |
| - flat: single column, linear exposure of callchains. |
| - graph: use a graph tree, displaying absolute overhead rates. |
| - fractal: like graph, but displays relative rates. Each branch of |
| the tree is considered as a new profiled object. + |
| Default: fractal,0.5. |
