I understand one still has to write a kernel driver to shut up the irq. How about writing a small bytecode interpreter to make event than unnecessary?
if you do that why not do a real driver.

An entire driver in bytecode?

no a real, non-bytecode driver.


Isn't the whole point of uio is to avoid writing a kernel mode driver?

As proposed, it doesn't quite accomplish it. With an additional bytecode interpreter, you can have a 100% userspace driver (the bytecode interpreter would be part of uio, not the driver).
