Q: How do I use callbacks registered with plugin_alloc_intr ? I figured how to use IO ports event_t event, int data, int op_size, int count, void *loc event = EVT_INPORT for in instructions, EVT_OUTPORT for out instructions data = port number op_size = number of bytes per transfer (eg. 1, 2, 4) count = number of transfers (I suppose for rep* IO) loc = generic pointer to transferred data, to typecast according op_size I suppose the following for interrupts event = EVT_INT data = 0 op_size = 0 count = 0 loc = pointer to a struct with registers Can somebody enlight me, please? I grep'ed the entire bochs plugin with plugin_alloc_intr, but didn't find any. EL
