The Starfire has a 512K 37 * register space. These registers can be accessed in the following way: 38 * - PCI config registers are always accessible through PCI config space 39 * - Full 512K space mapped into memory using PCI memory mapped access 40 * - 256-byte I/O space mapped through PCI I/O access 41 * - Full 512K space mapped through indirect I/O using PCI I/O access 42 * It's possible to use either memory mapped mode or I/O mode to access 43 * the registers, but memory mapped is usually the easiest. All registers 44 * are 32 bits wide and must be accessed using 32-bit operations. 45 */ 46 47/* 48 * Adaptec PCI vendor ID. 49 */ 50#define AD_VENDORID 0x9004 51 52/* 53 * AIC-6915 PCI device ID. 54 */ 55#define AD_DEVICEID_STARFIRE 0x6915 56 57/* 58 * AIC-6915 subsystem IDs.
