2 tristate "/dev/agpgart (AGP Support)"
3 depends on ALPHA || IA64 || PPC || X86
6 AGP (Accelerated Graphics Port) is a bus system mainly used to
7 connect graphics cards to the rest of the system.
9 If you have an AGP system and you say Y here, it will be possible to
10 use the AGP features of your 3D rendering video card. This code acts
11 as a sort of "AGP driver" for the motherboard's chipset.
13 If you need more texture memory than you can get with the AGP GART
14 (theoretically up to 256 MB, but in practice usually 64 or 128 MB
15 due to kernel allocation issues), you could use PCI accesses
16 and have up to a couple gigs of texture space.
18 Note that this is the only means to have X/GLX use
19 write-combining with MTRR support on the AGP bus. Without it, OpenGL
20 direct rendering will be a lot slower but still faster than PIO.
22 To compile this driver as a module, choose M here: the
23 module will be called agpgart.
25 You should say Y here if you want to use GLX or DRI.
30 tristate "ALI chipset support"
31 depends on AGP && X86_32
33 This option gives you AGP support for the GLX component of
34 X on the following ALi chipsets. The supported chipsets
35 include M1541, M1621, M1631, M1632, M1641,M1647,and M1651.
36 For the ALi-chipset question, ALi suggests you refer to
37 <http://www.ali.com.tw/eng/support/index.shtml>.
39 The M1541 chipset can do AGP 1x and 2x, but note that there is an
40 acknowledged incompatibility with Matrox G200 cards. Due to
41 timing issues, this chipset cannot do AGP 2x with the G200.
42 This is a hardware limitation. AGP 1x seems to be fine, though.
45 tristate "ATI chipset support"
46 depends on AGP && X86_32
48 This option gives you AGP support for the GLX component of
49 X on the ATI RadeonIGP family of chipsets.
52 tristate "AMD Irongate, 761, and 762 chipset support"
53 depends on AGP && X86_32
55 This option gives you AGP support for the GLX component of
56 X on AMD Irongate, 761, and 762 chipsets.
59 tristate "AMD Opteron/Athlon64 on-CPU GART support" if !IOMMU
63 This option gives you AGP support for the GLX component of
64 X using the on-CPU northbridge of the AMD Athlon64/Opteron CPUs.
65 You still need an external AGP bridge like the AMD 8151, VIA
66 K8T400M, SiS755. It may also support other AGP bridges when loaded
67 with agp_try_unsupported=1.
70 tristate "Intel 440LX/BX/GX, I8xx and E7x05 chipset support"
73 This option gives you AGP support for the GLX component of X
74 on Intel 440LX/BX/GX, 815, 820, 830, 840, 845, 850, 860, 875,
75 E7205 and E7505 chipsets and full support for the 810, 815, 830M,
76 845G, 852GM, 855GM, 865G and I915 integrated graphics chipsets.
81 tristate "NVIDIA nForce/nForce2 chipset support"
82 depends on AGP && X86_32
84 This option gives you AGP support for the GLX component of
85 X on NVIDIA chipsets including nForce and nForce2
88 tristate "SiS chipset support"
91 This option gives you AGP support for the GLX component of
92 X on Silicon Integrated Systems [SiS] chipsets.
94 Note that 5591/5592 AGP chipsets are NOT supported.
98 tristate "Serverworks LE/HE chipset support"
99 depends on AGP && X86_32
101 Say Y here to support the Serverworks AGP card. See
102 <http://www.serverworks.com/> for product descriptions and images.
105 tristate "VIA chipset support"
108 This option gives you AGP support for the GLX component of
109 X on VIA MVP3/Apollo Pro chipsets.
112 tristate "Intel 460GX chipset support"
113 depends on AGP && (IA64_DIG || IA64_GENERIC)
115 This option gives you AGP GART support for the Intel 460GX chipset
119 tristate "HP ZX1 chipset AGP support"
120 depends on AGP && (IA64_HP_ZX1 || IA64_HP_ZX1_SWIOTLB || IA64_GENERIC)
122 This option gives you AGP GART support for the HP ZX1 chipset
125 config AGP_ALPHA_CORE
126 tristate "Alpha AGP support"
127 depends on AGP && (ALPHA_GENERIC || ALPHA_TITAN || ALPHA_MARVEL)
131 tristate "Apple UniNorth & U3 AGP support"

134 This option gives you AGP support for Apple machines with a
135 UniNorth or U3 (Apple G5) bridge.
138 tristate "Transmeta Efficeon support"
139 depends on AGP && X86_32
