Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

/* Board configuration array.
|
|
* This array defines the hardware irq and address for up to IP2_MAX_BOARDS
|
|
* (4 supported per ip2_types.h) ISA board addresses and irqs MUST be specified,
|
|
* PCI and EISA boards are probed for and automagicly configed
|
|
* iff the addresses are set to 1 and 2 respectivily.
|
|
* 0x0100 - 0x03f0 == ISA
|
|
* 1 == PCI
|
|
* 2 == EISA
|
|
* 0 == (skip this board)
|
|
* This array defines the hardware addresses for them. 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. Those values are configurable from insmod parameters in the
|
|
* case of modules or from command line parameters (ip2=io,irq) when
|
|
