6 AGP (Accelerated Graphics Port) is a bus system mainly used to
7 connect graphics cards to the rest of the system.
8
9 If you have an AGP system and you say Y here, it will be possible to
10 use the AGP features of your 3D rendering video card. This code acts
11 as a sort of "AGP driver" for the motherboard's chipset.
12
13 If you need more texture memory than you can get with the AGP GART
14 (theoretically up to 256 MB, but in practice usually 64 or 128 MB
15 due to kernel allocation issues), you could use PCI accesses
16 and have up to a couple gigs of texture space.
17
Adrian Bunk1311c242006-02-10 11:56:30 +010018 Note that this is the only means to have X/GLX use
Linus Torvalds1da177e2005-04-16 15:20:36 -070019 write-combining with MTRR support on the AGP bus. Without it, OpenGL
20 direct rendering will be a lot slower but still faster than PIO.
21
Linus Torvalds1da177e2005-04-16 15:20:36 -070022 To compile this driver as a module, choose M here: the
23 module will be called agpgart.
24
Adrian Bunk1311c242006-02-10 11:56:30 +010025 You should say Y here if you want to use GLX or DRI.
26
27 If unsure, say N.

Linus Torvalds1da177e2005-04-16 15:20:36 -070035 include M1541, M1621, M1631, M1632, M1641,M1647,and M1651.
36 For the ALi-chipset question, ALi suggests you refer to
37 <http://www.ali.com.tw/eng/support/index.shtml>.
38
39 The M1541 chipset can do AGP 1x and 2x, but note that there is an
40 acknowledged incompatibility with Matrox G200 cards. Due to
41 timing issues, this chipset cannot do AGP 2x with the G200.
42 This is a hardware limitation. AGP 1x seems to be fine, though.
