drivers/char/agp/Kconfig v3.0-rc7

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.

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.

This option gives you AGP support for the GLX component of
X on the ATI RadeonIGP family of chipsets.

This option gives you AGP support for the GLX component of
X on AMD Irongate, 761, and 762 chipsets.

This option gives you AGP support for the GLX component of
X using the on-CPU northbridge of the AMD Athlon64/Opteron CPUs.
You still need an external AGP bridge like the AMD 8151, VIA
K8T400M, SiS755. It may also support other AGP bridges when loaded
with agp_try_unsupported=1.

This option gives you AGP support for the GLX component of X
on Intel 440LX/BX/GX, 815, 820, 830, 840, 845, 850, 860, 875,
E7205 and E7505 chipsets and full support for the 810, 815, 830M,
845G, 852GM, 855GM, 865G and I915 integrated graphics chipsets.

This option gives you AGP support for the GLX component of
X on NVIDIA chipsets including nForce and nForce2

This option gives you AGP support for the GLX component of
X on Silicon Integrated Systems [SiS] chipsets.

Note that 5591/5592 AGP chipsets are NOT supported.

Say Y here to support the Serverworks AGP card.  See
<http://www.serverworks.com/> for product descriptions and images.

This option gives you AGP support for the GLX component of
X on VIA MVP3/Apollo Pro chipsets.

This option gives you AGP GART support for the Intel 460GX chipset
for IA64 processors.

This option gives you AGP GART support for the HP ZX1 chipset
for IA64 processors.

This option gives you AGP GART support for the HP Quicksilver
AGP bus adapter on HP PA-RISC machines (Ok, just on the C8000
workstation...)

This option gives you AGP support for Apple machines with a
UniNorth or U3 (Apple G5) bridge.

This option gives you AGP support for the Transmeta Efficeon
series processors with integrated northbridges.

This option gives you AGP GART support for the SGI TIO chipset
for IA64 processors.
