Greets, I have a few questions regarding writing a PCI device driver with I/O address access to the PCI chip as opposed to memory mapped access: 1. what does the kernel do/want when it attaches the driver? 2. which pci_* functions are relevant for I/O access to PCI chip? 3. what does pci_attach() do? 4. many of the examples in /usr/src/sys/pci have the xx_softc structure. is this thee structure for accessing and controlling the PCI chip and whatever other chips are on the device?
