The Starfire has a 512K * register space. These registers can be accessed in the following way: * - PCI config registers are always accessible through PCI config space * - Full 512K space mapped into memory using PCI memory mapped access * - 256-byte I/O space mapped through PCI I/O access * - Full 512K space mapped through indirect I/O using PCI I/O access * It's possible to use either memory mapped mode or I/O mode to access * the registers, but memory mapped is usually the easiest. All registers * are 32 bits wide and must be accessed using 32-bit operations. */ /* * AIC-6915 subsystem IDs. Adaptec uses the subsystem ID to identify * the exact kind of NIC on which the ASIC is mounted. Currently there * are six different variations. Note: the Adaptec manual lists code 0x28 * for two different NICs: the 62044 and the 69011/TX. This is a typo: * the code for the 62044 is really 0x18. * * Note that there also appears to be an 0x19 code for a newer rev * 62044 card. */ #define AD_SUBSYSID_62011_REV0 0x0008 /* single port 10/100baseTX 64-bit */ #define AD_SUBSYSID_62011_REV1 0x0009 /* single port 10/100baseTX 64-bit */ #define AD_SUBSYSID_62022 0x0010 /* dual port 10/100baseTX 64-bit */ #define AD_SUBSYSID_62044_REV0 0x0018 /* quad port 10/100baseTX 64-bit */ #define AD_SUBSYSID_62044_REV1 0x0019 /* quad port 10/100baseTX 64-bit */ #define AD_SUBSYSID_62020 0x0020 /* single port 10/100baseFX 64-bit */ #define AD_SUBSYSID_69011 0x0028 /* single port 10/100baseTX 32-bit */ /* * Starfire internal register space map.
