Yusuke Sato	43c4d998cf	perfboot.py: check 2 more event logs by default ... 'sf_stop_bootanim' is useful for tracking the time wasted by showing the 'outro' part of the boot animation. 'wm_boot_animation_done' is also useful for tracking user perceived boot time. (cherry-pick of cbcf2778c3) Bug: 22207911 Change-Id: I3549338a2161fa29675993c239f57809270797f8	2015-08-04 12:06:36 -07:00

Yasuhiro Matsuda	ab3798399d	Add a script to record Android boot time. ... perfboot.py repeats the record of each event log during Android boot specified times. By default, interval between measurements is adjusted in such a way that CPUs are cooled down sufficiently to avoid boot time slowdown caused by CPU thermal throttling. This script also works around the issue of dropbox slowing down boot time on userdebug build (http://b/20890386) by limiting the number of files to be created by dropbox. The result is output in a tab-separated value format. BUG: 22207911 Change-Id: I0ddbac5d1c941efda87bc6db6388d8194d4bb3dd	2015-07-30 14:16:15 +09:00
