7 AGP (Accelerated Graphics Port) is a bus system mainly used to
8 connect graphics cards to the rest of the system.
9
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.
13
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.
18
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.
22
23 To compile this driver as a module, choose M here: the
24 module will be called agpgart.
25
26 You should say Y here if you want to use GLX or DRI.
27
28 If unsure, say N.

31 tristate "ALI chipset support"
32 depends on AGP && X86_32
33 help
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/>.
39
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.

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.
