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

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