| * GIO bus addresses | |
| * | |
| * The Indigo and Indy have two GIO bus connectors. Indigo2 (all models) have | |
| * three physical connectors, but only two slots, GFX and EXP0. | |
| * | |
| * There is 10MB of GIO address space for GIO64 slot devices | |
| * slot# slot type address range size | |
| * ----- --------- ----------------------- ----- | |
| * 0 GFX 0x1f000000 - 0x1f3fffff 4MB | |
| * 1 EXP0 0x1f400000 - 0x1f5fffff 2MB | |
| * 2 EXP1 0x1f600000 - 0x1f9fffff 4MB | |
| * | |
| * There are un-slotted devices, HPC, I/O and misc devices, which are grouped | |
| * into the HPC address space. | |
| * - MISC 0x1fb00000 - 0x1fbfffff 1MB | |
| * | |
| * Following space is reserved and unused | |
| * - RESERVED 0x18000000 - 0x1effffff 112MB | |
| * | |
| * GIO bus IDs | |
| * | |
| * Each GIO bus device identifies itself to the system by answering a | |
| * read with an "ID" value. IDs are either 8 or 32 bits long. IDs less | |
| * than 128 are 8 bits long, with the most significant 24 bits read from | |
| * the slot undefined. | |
| * | |
| * 32-bit IDs are divided into | |
| * bits 0:6 the product ID; ranges from 0x00 to 0x7F. | |
| * bit 7 0=GIO Product ID is 8 bits wide | |
| * 1=GIO Product ID is 32 bits wide. | |
| * bits 8:15 manufacturer version for the product. | |
| * bit 16 0=GIO32 and GIO32-bis, 1=GIO64. | |
| * bit 17 0=no ROM present | |
| * 1=ROM present on this board AND next three words | |
| * space define the ROM. | |
| * bits 18:31 up to manufacturer. | |
| * | |
| * IDs above 0x50/0xd0 are of 3rd party boards. | |
| * | |
| * 8-bit IDs | |
| * 0x01 XPI low cost FDDI | |
| * 0x02 GTR TokenRing | |
| * 0x04 Synchronous ISDN | |
| * 0x05 ATM board [*] | |
| * 0x06 Canon Interface | |
| * 0x07 16 bit SCSI Card [*] | |
| * 0x08 JPEG (Double Wide) | |
| * 0x09 JPEG (Single Wide) | |
| * 0x0a XPI mez. FDDI device 0 | |
| * 0x0b XPI mez. FDDI device 1 | |
| * 0x0c SMPTE 259M Video [*] | |
| * 0x0d Babblefish Compression [*] | |
| * 0x0e E-Plex 8-port Ethernet | |
| * 0x30 Lyon Lamb IVAS | |
| * 0xb8 GIO 100BaseTX Fast Ethernet (gfe) | |
| * | |
| * [*] Device provide 32-bit ID. | |
