From 68a912857707864bbaaff9808717813105072a6e Mon Sep 17 00:00:00 2001 From: Patrick Benavoli Date: Wed, 31 Aug 2011 11:23:23 +0200 Subject: parameter-framework: initial commit BZ: 6081 Parameter-framework is still-under-development, Intel proprietary, multi-platform (standard C++, for now only linux, no dependency on Android) software that allows system-wide parameter management. It relies on a number of configurations files, from which it knows how / when to hand out settings towards the hardware (subsystems) at runtime. 3 kinds of configuration files are used: - Structure description files indicating the actual parameter structure, types, min/max values, data representation. - Configurable domain description file containing the actual distribution of parameters over different domains, that is, different set of configurations, each of which being dynamically activated based on selection criteria rules that are themselves configurable. Configurable domains file contain the tuned settings along the tuning process, that is during the period where the system is being tuned. - Binary settings file used to store the settings when the tuning process is complete. Changing any of those files causes no recompilation of the framework. This project is based on a open plugin architecture allowing any kind of subsystems to be handled, whatever their respective Endianness. It fully relies on the platform SW to provide it with with the kowledge of exisitng selection criteria (selected device, current mode), as well as change events that occuring on them, thus triggering the application of corresponding configuration settings wherever appropriate. It supports handling mutliple parameter classes (Audio, Energy management) through TCP/IP interface. For now tuning commands can be sent to parameter-framework instances through a command-line utility, via adb over USB or via ethernet/WIFI.
