Benefits of Using the Driver Framework

Using the Driver Framework to build bus and device drivers in the ChorusOS operating system provides the following benefits to the user:

• A structured framework, easing the task of building drivers

• Hierarchical structure of drivers in Driver Framework mirrors hardware structure

• Ensures compliance and functionality within the ChorusOS operating system

• Enables the user to develop multi-bus device drivers, which may run on all buses supporting the Common Bus Driver Interface

• Drivers built with the Driver Framework are homogeneous across various system profiles (flat memory, protected memory, virtual memory)

• Allows dynamic configuration (and re-configuration) needed for plug-and-play, hot-plug and hot-swap support

• Supports the binary driver model

• APIs are version resilient

• Is adaptive (in terms of the memory footprint and complexity) to the various system profiles and customer requirements

• Supports the dynamic loading and unloading of driver components

• Meets real-time requirements, by providing non-blocking (asynchronous) run-time APIs
