  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.

 30config AGP_ALI
 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.

 45config AGP_ATI
 46	tristate "ATI chipset support"
 47	depends on AGP && X86_32

 59config AGP_AMD64

 62	help
 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.

 75	  on Intel 440LX/BX/GX, 815, 820, 830, 840, 845, 850, 860, 875,
 76	  E7205 and E7505 chipsets and full support for the 810, 815, 830M,
 77	  845G, 852GM, 855GM, 865G and I915 integrated graphics chipsets.
