2 tristate "/dev/agpgart (AGP Support)" if !GART_IOMMU
3 default y if GART_IOMMU
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 XFree4/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 You should say Y here if you use XFree86 3.3.6 or 4.x and want to
22 use GLX or DRI. If unsure, say N.
24 This driver is available as a module. If you want to compile it as
25 a module, say M here and read <file:Documentation/modules.txt>. The
26 module will be called agpgart.
29 tristate "ALI chipset support"
30 depends on AGP && X86 && !X86_64
32 This option gives you AGP support for the GLX component of
33 XFree86 4.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.
43 You should say Y here if you use XFree86 3.3.6 or 4.x and want to
44 use GLX or DRI. If unsure, say N.
47 tristate "AMD Irongate, 761, and 762 chipset support"
48 depends on AGP && X86 && !X86_64
50 This option gives you AGP support for the GLX component of
51 XFree86 4.x on AMD Irongate, 761, and 762 chipsets.
53 You should say Y here if you use XFree86 3.3.6 or 4.x and want to
54 use GLX or DRI. If unsure, say N.
57 tristate "AMD Opteron/Athlon64 on-CPU GART support"
61 This option gives you AGP support for the GLX component of
62 XFree86 4.x using the on-CPU AGP bridge of the AMD Athlon64/Opteron CPUs.
63 You should say Y here if you use XFree86 3.3.6 or 4.x and want to
64 use GLX or DRI. If unsure, say N

72 E7205 and E7505 chipsets and full support for the 810, 815, 830M, 845G,
73 852GM, 855GM and 865G integrated graphics chipsets.
75 You should say Y here if you use XFree86 3.3.6 or 4.x and want to
76 use GLX or DRI, or if you have any Intel integrated graphics
77 chipsets. If unsure, say Y.
80 tristate "NVIDIA nForce/nForce2 chipset support"
81 depends on AGP && X86 && !X86_64
