config AGP tristate "/dev/agpgart (AGP Support)" depends on ALPHA || IA64 || PARISC || PPC || X86 depends on PCI ---help--- AGP (Accelerated Graphics Port) is a bus system mainly used to connect graphics cards to the rest of the system. If you have an AGP system and you say Y here, it will be possible to use the AGP features of your 3D rendering video card. This code acts as a sort of "AGP driver" for the motherboard's chipset. If you need more texture memory than you can get with the AGP GART (theoretically up to 256 MB, but in practice usually 64 or 128 MB due to kernel allocation issues), you could use PCI accesses and have up to a couple gigs of texture space. Note that this is the only means to have X/GLX use write-combining with MTRR support on the AGP bus. Without it, OpenGL direct rendering will be a lot slower but still faster than PIO. To compile this driver as a module, choose M here: the module will be called agpgart. You should say Y here if you want to use GLX or DRI. If unsure, say N. config AGP_ALI tristate "ALI chipset support" depends on AGP && X86_32 ---help--- This option gives you AGP support for the GLX component of X on the following ALi chipsets. The supported chipsets include M1541, M1621, M1631, M1632, M1641,M1647,and M1651. For the ALi-chipset question, ALi suggests you refer to . The M1541 chipset can do AGP 1x and 2x, but note that there is an acknowledged incompatibility with Matrox G200 cards. Due to timing issues, this chipset cannot do AGP 2x with the G200. This is a hardware limitation. AGP 1x seems to be fine, though. config AGP_ATI tristate "ATI chipset support" depends on AGP && X86_32 ---help--- This option gives you AGP support for the GLX component of X on the ATI RadeonIGP family of chipsets. config AGP_AMD tristate "AMD Irongate, 761, and 762 chipset support" depends on AGP && X86_32 help This option gives you AGP support for the GLX component of X on AMD Irongate, 761, and 762 chipsets. config AGP_AMD64 tristate "AMD Opteron/Athlon64 on-CPU GART support" if !IOMMU depends on AGP && X86 default y if IOMMU help This option gives you AGP support for the GLX component of X using the on-CPU northbridge of the AMD Athlon64/Opteron CPUs. You still need an external AGP bridge like the AMD 8151, VIA K8T400M, SiS755. It may also support other AGP bridges when loaded with agp_try_unsupported=1. config AGP_INTEL tristate "Intel 440LX/BX/GX, I8xx and E7x05 chipset support" depends on AGP && X86 help This option gives you AGP support for the GLX component of X on Intel 440LX/BX/GX, 815, 820, 830, 840, 845, 850, 860, 875, E7205 and E7505 chipsets and full support for the 810, 815, 830M, 845G, 852GM, 855GM, 865G and I915 integrated graphics chipsets. config AGP_NVIDIA tristate "NVIDIA nForce/nForce2 chipset support" depends on AGP && X86_32 help This option gives you AGP support for the GLX component of X on NVIDIA chipsets including nForce and nForce2 config AGP_SIS tristate "SiS chipset support" depends on AGP help This option gives you AGP support for the GLX component of X on Silicon Integrated Systems [SiS] chipsets. Note that 5591/5592 AGP chipsets are NOT supported. config AGP_SWORKS tristate "Serverworks LE/HE chipset support" depends on AGP && X86_32 help Say Y here to support the Serverworks AGP card. See for product descriptions and images. config AGP_VIA tristate "VIA chipset support" depends on AGP help This option gives you AGP support for the GLX component of X on VIA MVP3/Apollo Pro chipsets. config AGP_I460 tristate "Intel 460GX chipset support" depends on AGP && (IA64_DIG || IA64_GENERIC) help This option gives you AGP GART support for the Intel 460GX chipset for IA64 processors. config AGP_HP_ZX1 tristate "HP ZX1 chipset AGP support" depends on AGP && (IA64_HP_ZX1 || IA64_HP_ZX1_SWIOTLB || IA64_GENERIC) help This option gives you AGP GART support for the HP ZX1 chipset for IA64 processors. config AGP_PARISC tristate "HP Quicksilver AGP support" depends on AGP && PARISC && 64BIT help This option gives you AGP GART support for the HP Quicksilver AGP bus adapter on HP PA-RISC machines (Ok, just on the C8000 workstation...) config AGP_ALPHA_CORE tristate "Alpha AGP support" depends on AGP && (ALPHA_GENERIC || ALPHA_TITAN || ALPHA_MARVEL) default AGP config AGP_UNINORTH tristate "Apple UniNorth & U3 AGP support" depends on AGP && PPC_PMAC help This option gives you AGP support for Apple machines with a UniNorth or U3 (Apple G5) bridge. config AGP_EFFICEON tristate "Transmeta Efficeon support" depends on AGP && X86_32 help This option gives you AGP support for the Transmeta Efficeon series processors with integrated northbridges. config AGP_SGI_TIOCA tristate "SGI TIO chipset AGP support" depends on AGP && (IA64_SGI_SN2 || IA64_GENERIC) help This option gives you AGP GART support for the SGI TIO chipset for IA64 processors.
