Special * addresses are EISA and PCI which go sniffing for boards. * In a multiboard system the position in the array determines which port * devices are assigned to each board: * board 0 is assigned ttyF0.. to ttyF63, * board 1 is assigned ttyF64 to ttyF127, * board 2 is assigned ttyF128 to ttyF191, * board 3 is assigned ttyF192 to ttyF255. * * In PCI and EISA bus systems each range is mapped to card in * monotonically increasing slot number order, ISA position is as specified * here. * If the irqs are ALL set to 0,0,0,0 all boards operate in * polled mode. For interrupt operation ISA boards require that the IRQ be * specified, while PCI and EISA boards any nonzero entry * will enable interrupts using the BIOS configured irq for the board. * An invalid irq entry will default to polled mode for that card and print * console warning. * When the driver is loaded as a module these setting can be overridden on the * modprobe command line or on an option line in /etc/modprobe.conf. * If the driver is built-in the configuration must be * set here for ISA cards and address set to 1 and 2 for PCI and EISA. * * Here is an example that shows most if not all possibe combinations: *static ip2config_t ip2config = *{ * {11,1,0,0}, // irqs * { // Addresses * 0x0308, // Board 0, ttyF0 - ttyF63// ISA card at io=0x308, irq=11 * 0x0001, // Board 1, ttyF64 - ttyF127//PCI card configured by BIOS * 0x0000, // Board 2, ttyF128 - ttyF191// Slot skipped * 0x0002 // Board 3, ttyF192 - ttyF255//EISA card configured by BIOS * // but polled not irq driven * } *}; */ /* this structure is zeroed out because the suggested method is to configure * the driver as a module, set up the parameters with an options line in * /etc/modprobe.conf and load with modprobe or kmod, the kernel * module loader */ /* This structure is NOW always initialized when the driver is initialized. * Compiled in defaults MUST be added to the io and irq arrays in * ip2.c.
