The procedure is outlined as follows: * * 1) Test bit 4 (CAP_LIST) of the PCI status register of the device * to determine wether or not this device implements any extended * capabilities. If this bit is zero, then the device is a PCI 2.1 * or earlier device and is not AGP capable, and we can conclude it * to be a PCI device. * * 2) If bit 4 of the status register is set, then the device implements * extended capabilities. There is an 8 bit wide capabilities pointer * register located at offset 0x34 in PCI config space which points to * the first capability in a linked list of extended capabilities that * this device implements. The lower two bits of this register are * reserved and MBZ so must be masked out. * * 3) The extended capabilities list is formed by one or more extended * capabilities structures which are aligned on DWORD boundaries. * The first byte of the structure is the capability ID (CAP_ID) * indicating what extended capability this structure refers to. The * second byte of the structure is an offset from the beginning of * PCI config space pointing to the next capability in the linked * list (NEXT_PTR) or NULL (0x00) at the end of the list. The lower * two bits of this pointer are reserved and MBZ. By examining the * CAP_ID of each capability and walking through the list, we will * either find the AGP_CAP_ID (0x02) indicating this device is an * AGP device, or we'll reach the end of the list, indicating it is * a PCI device. * * Mike A.
