Device drivers

Overview

The current device drivers are scattered through the shelter/lib/include/devs folder. There is two kinds of devices drivers:

• integrated: these one are used as a core part of the kernel, and aren't exposed through subsystem abstraction
• abstracted: these one are abstracted using a specific subsystem depending on the device type that provides a standard API both for drivers and consumers

Integrated drivers

For the moment, integrated drivers are implemented for the following devices:

• LAPIC devices
• IOAPIC devices

Abstracted drivers

For the moment, abstracted drivers are implemented for the following devices:
