32 // The generic device simply hooks ranges of ports, addresses, and irqs
33 // if they are not already hooked
35 // for each hooked port, it simply executes reads and writes and the same physical port,
36 // for each hooked memory range, it simply executes reads and writes on the same
37 // physical memory addresses
38 // for each hooked irq, it simply injects the irq into the VM
40 // These operations are also logged to serial (optionaly)
42 // If you attach a generic device *last*, you can capture all ops that are not
43 // already hooked, and capture a log of VM activity with respect to them.
45 // The effects of using the generic device should be identical to
46 // doing passthrough I/O, but with logging, and, of course, slower
