      AGP (Accelerated Graphics Port) is a bus system mainly used to

      connect graphics cards to the rest of the system.

​

      If you have an AGP system and you say Y here, it will be possible to

      use the AGP features of your 3D rendering video card. This code acts

      as a sort of "AGP driver" for the motherboard's chipset.

​

      If you need more texture memory than you can get with the AGP GART

      (theoretically up to 256 MB, but in practice usually 64 or 128 MB

      due to kernel allocation issues), you could use PCI accesses

      and have up to a couple gigs of texture space.

​

      Note that this is the only means to have X/GLX use

      write-combining with MTRR support on the AGP bus. Without it, OpenGL

      direct rendering will be a lot slower but still faster than PIO.

​

      To compile this driver as a module, choose M here: the

      module will be called agpgart.

​

      You should say Y here if you want to use GLX or DRI.

​

      If unsure, say N.

config AGP_ALI

    tristate "ALI chipset support"

    depends on AGP && X86_32

    ---help---

      This option gives you AGP support for the GLX component of

      X on the following ALi chipsets.  The supported chipsets

      include M1541, M1621, M1631, M1632, M1641,M1647,and M1651.

      For the ALi-chipset question, ALi suggests you refer to

      <http://www.ali.com.tw/>.

​

      The M1541 chipset can do AGP 1x and 2x, but note that there is an

      acknowledged incompatibility with Matrox G200 cards. Due to

      timing issues, this chipset cannot do AGP 2x with the G200.

      This is a hardware limitation. AGP 1x seems to be fine, though.
