fsodeviced

A device abstraction manager.

fsodeviced implements the FSO Device DBus API. This API allows peripheral control, such as managing audio, backlight brightness, LEDs, Vibrator, Accelerometer, and power control for devices without dedicated controlling daemon. It can deal with charging notification and RTC, forwarding button events and notifying about the system's idleness status.

It also ensures proper high-level suspend and resume preparation for available resources. Although it might be tempting, preparing a GSM modem for suspend can't sanely be handled in kernelspace, since you need to send several AT commands to it in order to prevent bogus wakeups. Which commands exactly is very device and situation specific, hence should be handled by userspace.

fsodeviced compiles to C and is very lightweight. It has been written to superseed all the device-specific control daemons Linux-based mobile systems have used in the past, such as the Zaurus' zaurusd, the Neo's neod, Kernel Concepts' deviced, etc. It also superseeds the non-customizable hald. It features a plugin-architecture, so you only pay for the features you really need.
