Marcel Moolenaar fe1c66b9d7 Rework the interrupt code and add support for interrupt filtering ... (INTR_FILTER). This includes: o Save a pointer to the sapic structure and IRQ for every vector, so that we can quickly EOI, mask and unmask the interrupt. o Add locking to the sapic code now that we can reprogram a sapic on multiple CPUs at the same time. o Use u_int for the vector and IRQ. We only have 256 vectors, so using a 64-bit type for it is rather excessive. o Properly handle concurrent registration of a handler for the same vector. Since vectors have a corresponding priority, we should not map IRQs to vectors in a linear fashion, but rather pick a vector that has a priority in line with the interrupt type. This is left for later. The vector/IRQ interchange has been untangled as much as possible to make this easier. Approved by: re (blacket)		2007-07-30 22:29:33 +00:00
