FUSD - a Linux Framework for User-Space Devices

Easier to write

Can use existing libraries

Can do other things (wait, file system, other device drivers, gui stuff, etc)

Can be swapped out

Stable .. no device driver can crash the system (but can do bad things)

• Uniform driver interface
• Replacement for current drivers
• high performance.
• No block devices yet
• Only works in C ... so far
