1. Terminology
-
Resources:
-
Devices resources (interrupts, DMA channels, I/O port addresses, and memory
addresses) must be registered by the Device Configuration Assistant so
that other devices will not try to use already assigned resources.
-
Device tree:
-
This is a tree structure capable of describing the system devices. An individual
node describes one device according to a set of rules (IEEE 1275).
-
Properties:
-
Each device node has a set of properties that describe characteristics
of the device (such as the resources assigned, the bus slot, and so on).
