6 perf-report - Read perf.data (created by perf record) and display the profile
11 'perf report' [-i <file> | --input=file]
15 This command displays the performance counter profile information recorded
22 Input file name. (default: perf.data)
26 Be more verbose. (show symbol address, etc)
30 Only consider symbols in these dsos. CSV that understands
31 file://filename entries.
34 Show the number of samples for each symbol
36 --showcpuutilization::
37 Show sample percentage for different cpu modes.
41 Show per-thread event counters
44 Only consider symbols in these comms. CSV that understands
45 file://filename entries.
48 Only consider these symbols. CSV that understands
49 file://filename entries.
53 Only display entries resolved to a symbol.
57 Sort by key(s): pid, comm, dso, symbol, parent.
61 regex filter to identify parent, see: '--sort parent'
65 Only display entries with parent-match.
68 --column-widths=<width[,width...]>::
69 Force each column width to the provided list, for large terminal
75 Use a special separator character and don't pad with spaces, replacing
76 all occurrences of this separator in symbol names (and other output)
77 with a '.' character, that thus it's the only non valid separator.
81 Dump raw trace in ASCII.
85 Display call chains using type and min percent threshold.
87 - flat: single column, linear exposure of call chains.
88 - graph: use a graph tree, displaying absolute overhead rates.
89 - fractal: like graph, but displays relative rates. Each branch of
90 the tree is considered as a new profiled object. +
94 Pretty printing style. key: normal, raw
96 --stdio:: Use the stdio interface.
98 --tui:: Use the TUI interface, that is integrated with annotate and allows
99 zooming into DSOs or threads, among other features. Use of --tui
100 requires a tty, if one is not present, as when piping to other
101 commands, the stdio interface is used.
112 Load module symbols. WARNING: This should only be used with -k and
117 Don't complain, do it.
119 --symfs=<directory>::
120 Look for files with symbols relative to this directory.
