jhb 2002/09/06 10:08:08 PDT Modified files: sys/i386/include pci_cfgreg.h sys/i386/pci pci_bus.c pci_cfgreg.c Log: - Add a pci_cfgintr_valid() function to see if a given IRQ is a valid IRQ for an entry in a PCIBIOS interrupt routing ($PIR) table. - Change pci_cfgintr() to except the current IRQ of a device as a fourth argument and to use that IRQ for the device if it is valid. - If an intpin entry in a $PIR entry has a link of 0, it means that that intpin isn't connected to anything that can trigger an interrupt. Thus, test the link against 0 to find invalid entries in the table instead of implicitly relying on the irqs field to be zero. In the machines I have looked at, intpin entries with a link of 0 often have the bits for all possible interrupts for PCI devices set.
