Subject: [PATCHSET 00/23] perf tools: Add support for hierachy view (v5)
Date: Fri, 5 Feb 2016 22:01:32 +0900 [thread overview]
Message-ID: <1454677315-7515-1-git-send-email-namhyung@kernel.org> (raw)
Hello,
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.
* Changes from v4)
- rebased onto the current acme/perf/core
- fix memory leak on callchian_merge error path (Arnaldo)
- fix a bug on perf-top regarding percent calculation
- split hierarchy filtering code
* Changes from v3)
- rebased onto the percent limit patchset v2
* Changes from v2)
- check memory allocation failure in hists__hierarchy_insert_entry (Jiri)
- remove unused rb_hierarchy_first() (Arnaldo)
- support callchain percent limit (Andi)
- break TUI context menu cleanup (Arnaldo)
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-v5' branch in my tree:

Any comments are welcome, thanks!
