This reverts commit f191f14407.
The AMD 751 and 761 chipsets are used on the UP1000, UP1100, and UP1500
OEM motherboards, but they neglect to do anything to make AGP work.
According to Ivan Kokshaysky:
There is quite fundamental conflict between the Alpha architecture and
x86 AGP implementation - Alpha is entirely cache coherent by design,
while x86 AGP is not (I mean native AGP DMA transactions, not a PCI over
AGP). There are no such things as non-cacheable mappings or software
support for cache flushing/invalidation on Alpha, so x86 AGP code won't
work on Nautilus.
So there's no point in allowing this driver to be configured on Alpha.

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.

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.
