3 tristate "/dev/agpgart (AGP Support)"
4 depends on ALPHA || IA64 || PARISC || PPC || X86
7 AGP (Accelerated Graphics Port) is a bus system mainly used to
8 connect graphics cards to the rest of the system.
10 If you have an AGP system and you say Y here, it will be possible to
11 use the AGP features of your 3D rendering video card. This code acts
12 as a sort of "AGP driver" for the motherboard's chipset.
14 If you need more texture memory than you can get with the AGP GART
15 (theoretically up to 256 MB, but in practice usually 64 or 128 MB
16 due to kernel allocation issues), you could use PCI accesses
17 and have up to a couple gigs of texture space.
19 Note that this is the only means to have X/GLX use
20 write-combining with MTRR support on the AGP bus. Without it, OpenGL
21 direct rendering will be a lot slower but still faster than PIO.
23 To compile this driver as a module, choose M here: the
24 module will be called agpgart.
26 You should say Y here if you want to use GLX or DRI.
31 tristate "ALI chipset support"
32 depends on AGP && X86_32
34 This option gives you AGP support for the GLX component of
35 X on the following ALi chipsets. The supported chipsets
36 include M1541, M1621, M1631, M1632, M1641,M1647,and M1651.
37 For the ALi-chipset question, ALi suggests you refer to
38 <http://www.ali.com.tw/>.
40 The M1541 chipset can do AGP 1x and 2x, but note that there is an
41 acknowledged incompatibility with Matrox G200 cards. Due to
42 timing issues, this chipset cannot do AGP 2x with the G200.
43 This is a hardware limitation. AGP 1x seems to be fine, though.
46 tristate "ATI chipset support"
47 depends on AGP && X86_32
49 This option gives you AGP support for the GLX component of
50 X on the ATI RadeonIGP family of chipsets.
53 tristate "AMD Irongate, 761, and 762 chipset support"
54 depends on AGP && X86_32
56 This option gives you AGP support for the GLX component of
57 X on AMD Irongate, 761, and 762 chipsets.
60 tristate "AMD Opteron/Athlon64 on-CPU GART support"
61 depends on AGP && X86 && AMD_NB
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"
74 This option gives you AGP support for the GLX component of X
75 on Intel 440LX/BX/GX, 815, 820, 830, 840, 845, 850, 860, 875,
76 E7205 and E7505 chipsets and full support for the 810, 815, 830M,
77 845G, 852GM, 855GM, 865G and I915 integrated graphics chipsets.
82 tristate "NVIDIA nForce/nForce2 chipset support"
83 depends on AGP && X86_32
85 This option gives you AGP support for the GLX component of
86 X on NVIDIA chipsets including nForce and nForce2
89 tristate "SiS chipset support"
92 This option gives you AGP support for the GLX component of
93 X on Silicon Integrated Systems [SiS] chipsets.
95 Note that 5591/5592 AGP chipsets are NOT supported.
99 tristate "Serverworks LE/HE chipset support"
100 depends on AGP && X86_32
102 Say Y here to support the Serverworks AGP card. See
103 <http://www.serverworks.com/> for product descriptions and images.
106 tristate "VIA chipset support"
107 depends on AGP && X86
109 This option gives you AGP support for the GLX component of
110 X on VIA MVP3/Apollo Pro chipsets.
113 tristate "Intel 460GX chipset support"
114 depends on AGP && IA64
116 This option gives you AGP GART support for the Intel 460GX chipset
120 tristate "HP ZX1 chipset AGP support"
121 depends on AGP && IA64
123 This option gives you AGP GART support for the HP ZX1 chipset
127 tristate "HP Quicksilver AGP support"
128 depends on AGP && PARISC && 64BIT
130 This option gives you AGP GART support for the HP Quicksilver
131 AGP bus adapter on HP PA-RISC machines (Ok, just on the C8000
134 config AGP_ALPHA_CORE
135 tristate "Alpha AGP support"

140 tristate "Apple UniNorth & U3 AGP support"
141 depends on AGP && PPC_PMAC
143 This option gives you AGP support for Apple machines with a
144 UniNorth or U3 (Apple G5) bridge.
147 tristate "Transmeta Efficeon support"
