Hi All, I’m trying to find a way, if any, to craft a driver ( without any hardware) to install an ISR at some IDT vector. It is going to run under VM ( always ), and want to be able to use say some high vector number like 0x7e ( usually the ones that are expected to be used by device interrupts). May be this is not possible, if the underlying mechanism is MSI or MSIe and vector assignment is purely under kernel control. I would appreciate, any thoughts and answer(s) on it.
