Special 41 * addresses are EISA and PCI which go sniffing for boards. 42 43 * In a multiboard system the position in the array determines which port 44 * devices are assigned to each board: 45 * board 0 is assigned ttyF0.. to ttyF63, 46 * board 1 is assigned ttyF64 to ttyF127, 47 * board 2 is assigned ttyF128 to ttyF191, 48 * board 3 is assigned ttyF192 to ttyF255. 49 * 50 * In PCI and EISA bus systems each range is mapped to card in 51 * monotonically increasing slot number order, ISA position is as specified 52 * here. 53 54 * If the irqs are ALL set to 0,0,0,0 all boards operate in 55 * polled mode. For interrupt operation ISA boards require that the IRQ be 56 * specified, while PCI and EISA boards any nonzero entry 57 * will enable interrupts using the BIOS configured irq for the board. 58 * An invalid irq entry will default to polled mode for that card and print 59 * console warning. 60 61 * When the driver is loaded as a module these setting can be overridden on the 62 * modprobe command line or on an option line in /etc/modprobe.conf. 63 * If the driver is built-in the configuration must be 64 * set here for ISA cards and address set to 1 and 2 for PCI and EISA. 65 * 66 * Here is an example that shows most if not all possibe combinations: 67 68 *static ip2config_t ip2config = 69 *{ 70 * {11,1,0,0}, // irqs 71 * { // Addresses 72 * 0x0308, // Board 0, ttyF0 - ttyF63// ISA card at io=0x308, irq=11 73 * 0x0001, // Board 1, ttyF64 - ttyF127//PCI card configured by BIOS 74 * 0x0000, // Board 2, ttyF128 - ttyF191// Slot skipped 75 * 0x0002 // Board 3, ttyF192 - ttyF255//EISA card configured by BIOS 76 * // but polled not irq driven 77 * } 78 *}; 79 */ 80 81 /* this structure is zeroed out because the suggested method is to configure 82 * the driver as a module, set up the parameters with an options line in 83 * /etc/modprobe.conf and load with modprobe or kmod, the kernel 84 * module loader 85 */ 86 87 /* This structure is NOW always initialized when the driver is initialized. 88 * Compiled in defaults MUST be added to the io and irq arrays in 89 * ip2.c.
