3 AGP (Accelerated Graphics Port) is a bus system mainly used to connect graphics
|
|
al@19583
|
4 cards to the rest of the system.

|
6 If you have an AGP system, it will be possible to use the AGP features of your
|
|
al@19583
|
7 3D rendering video card. This code acts as a sort of "AGP driver" for the
|
|
al@19583
|
8 motherboard's chipset.

10 If you need more texture memory than you can get with the AGP GART
|
|
al@19583
|
11 (theoretically up to 256 MB, but in practice usually 64 or 128 MB due to Kernel
|
|
al@19583
|
12 allocation issues), you could use PCI accesses and have up to a couple gigs of
|
|
al@19583
|
13 texture space.
|
|
al@19583
|
14
|
|
al@19583
|
15 Note that this is the only means to have X/GLX use write-combining with MTRR
|
|
al@19583
|
16 support on the AGP bus. Without it, OpenGL direct rendering will be a lot
|
|
al@19583
|
17 slower but still faster than PIO.
|
|
al@19583
|
18
|
|
al@19583
|
19 You should use this module if you want to use GLX or DRI.

|
|
al@19583
|
24 M1632, M1641,M1647,and M1651. For the ALi-chipset question, ALi suggests
|
|
al@19583
|
25 you refer to <http://www.ali.com.tw/>.
|
|
al@19583
|

34 on-CPU northbridge of the AMD Athlon64/Opteron CPUs. You still need an
|
|
al@19583
|
35 external AGP bridge like the AMD 8151, VIA K8T400M, SiS755. It may also
|
|
al@19583
|
36 support other AGP bridges when loaded with agp_try_unsupported=1.
|
|
al@19583
