power.stats: Add AidlStateResidencyDataProvider 2019-02-26T23:05:17+00:00 Benjamin Schwartz bsschwar@google.com 2019-02-06T20:37:57+00:00 6317ff3771ad3cae10b6159463ab549d54a13741 Some drivers that we want to collect power stats from are pass-through and would require significant changes in order to provide a sysfs node that the current power stats framework can pull stats from. These pass-through drivers typically have a userspace daemon that is capable of keeping track of the power stats and providing them to the power.stats HAL service, but currently have no way to do that. The AidlStateResidencyDataProvider will provide a vendor binder service that will allow data sources to register a callback that will get invoked when stats are requested from power.stats HAL. Bug: 117585786 Test: Created a dummy service to register a callback using that provides data for mock entities. Tested that things continue to function when killing either the dummy service or killing power.stats service. Also tested cases where the dummy service provides data for unrecognized entities, or states. Finally, I tested that an error gets logged in logcat if the callback latency exceeds some threshold.

power.stats HAL: optional "delta" arg to debug 2019-02-14T01:31:39+00:00 Kelly Rossmoyer krossmo@google.com 2019-02-13T22:52:18+00:00 741f76c727562eb2101615631d6da348ed9cb83f This CL adds a built-in delta tracking/calculation facility in power.stats HAL's implementation of the standard debug() interface. Right now, doing lshal debug android.hardware.power.stats@1.0::IPowerStats/default only displays the current values of all supported power stats. With this CL in place, that command now looks for the optional "delta" argument at the end of the line. When it is present, behavior changes as follows: * a timestamp is captured for the current values * a snapshot is captured of the current values * deltas from the previous timestamp and snapshot are displayed * the very first time "delta" is used after boot, the calculated deltas show up as "none" Note that no behavior is changed when the command is run without the optional "delta" arg, and interspersing non-"delta" commands with "delta" commands won't have any impact (the timestamp and snapshot are not modified by non-"delta" commands). See bug for example output. Bug: 124388963 Test: Ran on multiple device types with various power consumption configurations and verified that the output was both complete and accurate.
