11 // The generic device simply hooks ranges of ports, addresses, and irqs
12 // if they are not already hooked
14 // for each hooked port, it simply executes reads and writes and the same physical port,
15 // for each hooked memory range, it simply executes reads and writes on the same
16 // physical memory addresses
17 // for each hooked irq, it simply injects the irq into the VM
19 // These operations are also logged to serial (optionaly)
21 // If you attach a generic device *last*, you can capture all ops that are not
22 // already hooked, and capture a log of VM activity with respect to them.
24 // The effects of using the generic device should be identical to
25 // doing passthrough I/O, but with logging, and, of course, slower
