Frederic Weisbecker 4eb3e4788b perf report: Add support for callchain graph output Currently, the printing of callchains is done in a single vertical level, this is the "flat" mode: 8.25% [k] copy_user_generic_string 4.19% copy_user_generic_string generic_file_aio_read do_sync_read vfs_read sys_pread64 system_call_fastpath pread64 This patch introduces a new "graph" mode which provides a hierarchical output of factorized paths recursively sorted: 8.25% [k] copy_user_generic_string \| \|--4.31%-- generic_file_aio_read \| do_sync_read \| vfs_read \| \| \| \|--4.19%-- sys_pread64 \| \| system_call_fastpath \| \| pread64 \| \| \| --0.12%-- sys_read \| system_call_fastpath \| __read \| \|--3.24%-- generic_file_buffered_write \| __generic_file_aio_write_nolock \| generic_file_aio_write \| do_sync_write \| reiserfs_file_write \| vfs_write \| \| \| \|--3.14%-- sys_pwrite64 \| \| system_call_fastpath \| \| __pwrite64 \| \| \| --0.10%-- sys_write [...] The command line has then changed. By providing the -c option, the callchain will output in the flat mode by default. But you can override it: perf report -c graph or perf report -c flat You can also pass the abreviated mode: perf report -c g or perf report -c gra will both make use of the graph mode.
