Low memory devices place special emphasis on memory constraints and cpu utilization. We want to expose a set of build configurations that allow these devices to fine tune resource usage during OTA installation. Our strategy will be the following. 1. For any tunable needed in first stage init, read the .ro prop during ota installation, propogate the configuration to SnapshotUpdateStatus proto, then read the property from /metadata upon first reboot (since .ro properties are not available here) 2. For tunables which aren't needed until second stage init, read the .ro prop directly. This first CL will just add the build configurations to the build system. Subsequent CL's will forward the configs to protobufs and snapuserd daemon Bug: 332255580 Test: th Change-Id: I31b36b42f8fba997c772fe1a4ba99b17128b3eca |
