2 tristate "/dev/agpgart (AGP Support)" if !GART_IOMMU && !M68K && !ARM
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 To compile this driver as a module, choose M here: the
25 module will be called agpgart.
28 tristate "ALI chipset support"
29 depends on AGP && X86 && !X86_64
31 This option gives you AGP support for the GLX component of
32 XFree86 4.x on the following ALi chipsets. The supported chipsets
33 include M1541, M1621, M1631, M1632, M1641,M1647,and M1651.
34 For the ALi-chipset question, ALi suggests you refer to
35 <http://www.ali.com.tw/eng/support/index.shtml>.
37 The M1541 chipset can do AGP 1x and 2x, but note that there is an
38 acknowledged incompatibility with Matrox G200 cards. Due to
39 timing issues, this chipset cannot do AGP 2x with the G200.
40 This is a hardware limitation. AGP 1x seems to be fine, though.
42 You should say Y here if you use XFree86 3.3.6 or 4.x and want to
43 use GLX or DRI. If unsure, say N.
46 tristate "ATI chipset support"
47 depends on AGP && X86 && !X86_64

50 XFree86 4.x on the ATI RadeonIGP family of chipsets.
52 You should say Y here if you use XFree86 3.3.6 or 4.x and want to
53 use GLX or DRI. If unsure, say N.

59 This option gives you AGP support for the GLX component of
60 XFree86 4.x on AMD Irongate, 761, and 762 chipsets.

63 use GLX or DRI. If unsure, say N.
66 tristate "AMD Opteron/Athlon64 on-CPU GART support" if !GART_IOMMU
68 default y if GART_IOMMU
70 This option gives you AGP support for the GLX component of
71 XFree86 4.x using the on-CPU northbridge of the AMD Athlon64/Opteron CPUs.
72 You still need an external AGP bridge like the AMD 8151, VIA
73 K8T400M, SiS755. It may also support other AGP bridges when loaded
74 with agp_try_unsupported=1.
75 You should say Y here if you use XFree86 3.3.6 or 4.x and want to
76 use GLX or DRI. If unsure, say Y

85 852GM, 855GM, 865G and I915 integrated graphics chipsets.
87 You should say Y here if you use XFree86 3.3.6 or 4.x and want to
