| | 23 | ''Device'' section describes single GPU in a computer. Because there are multiple cards in one computer, each needs to have its own ''Device'' section. To determine which section is connected to which card, GPU's physical address is used (which can be read using ''lspci'' command - usually lower address number is connected to PCI port located higher on motherboard). Each ''device'' needs to know what monitors are connected to it and on which port. Therefore, the use of DFP-[1-6] parameters is needed. DFP-[1-6] are ports on GPU. In ATI cards they are numbered starting from the one located furthest from the mainboard. In ATI cards with mixed miniDP and DVI ports, DFP-[1-4] are miniDP and DFP-[5-6] are DVI ports, also starting from the furthest from the mainboard. |
