------- Additional Comments From [EMAIL PROTECTED] 2003-22-07 07:21 -------
Thank you Hui for doing this,
The kernel patch does not apply cleanly to vanilla 2.4.18 neither 2.4.19. I
applied it by hand against 2.4.18(*) whitch is the most close with your patch.
The patch against xfree-cvs does not applied cleanly too (obviously as it's
against a cvs version) against cvs of yesterday (2003-07-21), so I applied it
by hand too.
Now the kernel during boot gives me this nice info :) :

But unfortunately after compiling xfree with the patch too, when starting X I
get an kernel oops:

Maybe I've forgotten to include something in the kernel build? I have the
framebuffer compiled in the kernel (not modular), the selected driver is
radeon, but the same happens with vesafb too. But FWIK the kernel's
framebuffer driver is not used by xfree so I can not understand this oops. Any
sugestions welkomed. BTW, as for your comments about the patch working in agp4
only I added this in my XF86Config-4 (Including all the Device section for
completeness):
Section "Device"
Identifier "device1"
VendorName "ATI Technologies Inc"
BoardName "ATI Radeon"
Driver "radeon"
Option "DPMS"
Option "AGPMode" "4" <- This is what I added
EndSection
I tried agptool too and here's the output with your patch:
agptool by Dave Jones. <[EMAIL PROTECTED]>
Found AGP host bridge.
1002:cab2 :-1002:cab2
Host capabilities:
Compliant with version 2.0 of the AGP standard.

Here's the output without your patch:
agptool by Dave Jones. <[EMAIL PROTECTED]>
Found AGP host bridge.
1002:cab2 :-1002:cab2
Host capabilities:
Compliant with version 2.0 of the AGP standard.

System is capable of doing x4 AGP.
Couldn't open /dev/agpgart
(*) I tried the kernel patch to apply to vanilla 2.4.22-pre7 too but from
kernel 2.4.21 there is no num_of_masks member to the agp_bridge_data struct.
I'll look at the conversion of the other drivers, the change in the kernel
happened during 2.4.21.
Hope this helps, and of course if you need some test being done, just ask.
Bye,
Fredi
