This patchset implements a new feature that collects hist entries in a hierachical manner. That means lower-level entries belong to an upper-level entry. The entry hierachy is built on the sort keys given, so users can set it whatever they want. It only shows top-level entries first, and user can expand/collapse it dynamically. This time I implemented it for every output browser including TUI. A screenshot on TUI looks like below: For normal output: $ perf report --tui Samples: 3K of event 'cycles:pp', Event count (approx.): 1695979674 Overhead Command Shared Object Symbol ------------------------------------------------------------------------ - 7.57% swapper [kernel.vmlinux] [k] intel_idle intel_idle cpuidle_enter_state cpuidle_enter call_cpuidle + cpu_startup_entry + 1.16 firefox firefox [.] 0x00000000000019433 + 0.97% firefox libpthread-2.22.so [.] pthread_mutex_lock ... With hierarchy view, $ perf report --tui --hierarchy Samples: 3K of event 'cycles:pp', Event count (approx.): 1695979674 Overhead Command / Shared Object / Symbol ------------------------------------------------------------------- + 76.30% firefox - 9.95% swapper - 9.51% [kernel.vmlinux] - 7.57 [k] intel_idle intel_idle cpuidle_enter_state cpuidle_enter call_cpuidle + cpu_startup_entry + 0.15% [k] __schedule + 0.12% [k] menu_select ... + 0.34% [sdhci] + 0.06% [e1000e] ... + 5.65% Xorg + 5.42% Socket Thread ... As you can see, overhead of an upper level entry is the sum of overhead of lower level entries. The entries are aligned by its order of matching sort keys. This is available from 'perf/hierarchy-v2' branch in my tree: git://git.kernel.org/pub/scm/linux/kernel/git/namhyung-perf.git Any comments are welcome, thanks!
