29.7 Network drivers

Things drivers may want to do that make emulation difficult:

• Call the 16-bit BIOS.
• Use the system DMA controller.
• Assume kernel virtual addresses are equivalent to physical addresses.
• Assume kernel virtual addresses can be mapped to physical addresses merely by adding a constant offset.
• Implement timeouts by busy-waiting on a global clock-tick counter.
• Busy-wait for interrupts. XXX This means that the OS must allow interrupts during execution of process-level driver code, and not just when all process-level activity is blocked.
