Goal

• Understand how I/O devices, their interrupt handlers and device drivers.

Reading Assignments

• MOS 5.1-5.3, 5.5-5.9

Discussion Topics

• What kind of abstraction would you like an operating system to provide for I/O devices?

• A complicated issue in designing a device driver is to provide asynchronous operations.  What design and implementation issues you will need to consider if you want to provide users with asynchronous operations?  Please list the issues you can think of and make some comments on each.
