2.5 AGP for 2.4.21-pre4

2.5 AGP for 2.4.21-pre4

[Brian Jackson]

This is a poor attempt at a backport of the 2.5.61 AGP subsystem by someone 
who doesn't know what he is doing and is in way over his head. That said, are 
there any "brave" souls out there that want to try this out with an AGP3 card 
and 2.4.21pre4. I compile/boot tested it with an old ati card, but I don't 
have an AGP 3.0 card/MB to test it on. I got into X and ran glxgears using 
this kernel(I am using it to finish writing this email)

http://www.mdrx.com/brian/2.4.21-pre4-2.5agp.diff.gz

caveats:
agp has to be built in to the kernel (no modules)

I did the following:
copied the drivers/char/agp directory from 2.5.61
copied include/asm-*/agp.h from 2.5.61
copied include/linux/*agp.h from 2.5.61
made some changes to drivers/char/agp/Makefile
on line 619&635 of frontend.c changed remap_page_range to only have 4
	arguments
line 705 generic.c changed SetPageLocked -->SetPageReserved
	(not sure if this is right, but Locked doesn't exist in 2.4 and I thought
	Reserved might work -- Let me know if this should be something else)
backend.c:241 & backend.c:263 commented references to 2.5 module stuff
	(therefore this only safe to be built into the kernel for now, any ideas what
	I should use here instead?)
added some device id's to drivers/char/agp/agp.h from
	2.5.61/include/linux/pci_ids.h
uninclude gfp.h & linux/page-flags.h from amd-k7-agp.c

What else I need to do:
change to old style module init stuff

This is nowhere near suitable for production use, but I would like some people 
that actually have AGP3 cards/MB's to try this out

P.S. All criticism is welcome even flaming since I am in a decent mood right 
now

P.S.S. To Dave Jones -- I thought 2.5 had support for VIA chipsets & AGP3, but 
I only saw config options for the 7205/7505

If CONFIG_AGP3 is set, then the agp3 routines in via-agp.c also get
built, so you get KT400 support.

That is what it looked like as I started looking through some of the code, I 
just wasn't sure. Thanks for the answer.

You patch deleted the definitions for the Via chipsets. After I added them
back the agpgart driver appeared to load correctly. When I try to start X I
get a black screen and have to shutdown and reboot to get video back. This
is with an AIW 9700 Pro and a Gigabyte GA-7VAXP KT400 based motherboard .

you mean for other parts of the chipset? Not for the agp bridge, right? Can 
you tell me which ones you added back in? I can add them to v2 which I am 
working on now to add module ability back.

Are you using DRI? I wasn't able to test with DRI, so that may not work 
correctly. I guess I should have said something about that :) Would it be 
possible for you to send some dmesg output. Maybe keep X from starting, get 
the output, and send it to me. Does 2.5 work in 8X mode for you?

Good I was hoping somebody with 8X hardware would try it out. BTW have you 
ever seen any other AIW cards before, I was curious if the new one looked any 
better or worse.

I tried the patch. The agpgart driver now loads and sets the apeture. When I
try to start X the video does not initialize properly and I get a black
screen. This is with an AIW Radeon 9700 Pro and a Gigabyte GA-7VAXP mother
board with a KT400 chipset.
