Userland Components and Drivers

This page lists and tracks the various user-level libraries and components that are available to use in seL4 system.

Libraries vs Components

We generally put generic device driver and component code into libraries, so that they can be used in various scenarios (in native seL4 processes, in CAmkES components, linked directly with clients, etc.).

Specific CAmkES components, seL4 processes, etc. wrap around the functionality provided by these libraries, performing relevant initialisation, etc. and providing the library's functionality as a service.

Below we list the various drives and other userland functionality we provide, and note whether it is available as a library, as a component, or in some other form. We also link to where it can be found.
