* uid_cputime: fix overflow when printing cputimeJin Qian2015-12-021-1/+1
| | | | | | | | cputime_t is u64. Use %llu instead of %u. Bug: 22461683 Change-Id: Ia9a343a826e62cc73d2f61caf15651aee0233e9a Signed-off-by: Jin Qian <jinqian@google.com>
* uid_cputime: Fixes double accounting race condition on task exit.Ruchi Kandoi2015-12-021-0/+5
| | | | | | | | | | | | | This avoids the race where a particular process is terminating and we read the show_uid_stats. At this time since the task_struct still exists and we will account for the terminating process as one of the active task, where as the stats would have been added in the task exit callback.

* uid_cputime: Extends the cputime functionality to report power per uidRuchi Kandoi2015-12-021-2/+10
| | | | | | | | | /proc/uid_cputime/show_uid_stats shows a third field power for each of the uids. It represents the power in the units (uAusec) Bug: 21498425 Change-Id: I52fdc5e59647e9dc97561a26d56f462a2689ba9c Signed-off-by: Ruchi Kandoi <kandoiruchi@google.com>

* proc: uid: Changes the thread notifier to profile event notifier.Ruchi Kandoi2015-12-021-33/+18
| | | | | | | In order to keep the code consistent with all other platforms, the thread notifier is changed to profile event notifier. Change-Id: I5b996c789927b42dacba10af6fe81a21866e2c8f
* proc: uid: Adds accounting for the cputimes per uid.jinqian2015-12-021-0/+253
Adds proc files /proc/uid_cputime/show_uid_stat and /proc/uid_cputime/remove_uid_range. show_uid_stat lists the total utime and stime for the active as well as terminated processes for each of the uids. Writing a range of uids to remove_uid_range will delete the accounting for all the uids within that range. Change-Id: I21d9210379da730b33ddc1a0ea663c8c9d2ac15b
