12.1 Introduction

This library provides default implementations of various functions needed by device drivers under the OSKit device driver framework. These default implementations can be used by the host OS, if appropriate, to make it easier to adopt the driver framework. The facilities provided include:

• Hardware resource management and tracking functions to allocate and free IRQs, I/O ports, DMA channels, etc.
• Device namespace management
• Memory allocation for device drivers
• Data buffer management

XXX: oskit_dev_init() call this to init libdev

XXX: oskit_dev_probe() call this after init to probe for devices
