Description Rogelio Noriega 2001-04-12 18:33:57 UTC
When using add-on Matrox G450 graphic card on Dell WS 220 and 530, 
agpgart is not probed.  I need to force it using "modprobe agpgart 
agp_try_unsupported=1" command

Comment 1 Mike A. Harris 2001-04-13 14:40:55 UTC
We have force loaded agpgart on mga and r128 for a while now.

Comment 2 Preston Brown 2001-04-13 15:55:12 UTC
Bill, is this a agpgart driver issue with the WS220's chipset?

Comment 3 Bill Nottingham 2001-04-13 16:12:30 UTC
Probably, yes, if we need to add the 'agp_try_unsupported' parameter.

Comment 4 Matt Wilson 2001-04-17 18:51:56 UTC
as a workaround, add:

options agpgart agp_try_unsupported=1

to /etc/modules.conf

Comment 5 Matt Wilson 2001-04-17 18:54:24 UTC
please add the output of "lspci; lspci -n" to this bugreport.

I need "lspci -vn" to get the subvendor id.  This G450 card is not supported
currently.  *ANY* G450 card that shows up as G400, automatically is unsupported
by XFree86, and requires at a minimum the output of "lspci -vn" to be submitted
for the card to be detected properly in some future version of XFree86.

This is a bad side effect of using subvendor id's on PCI cards..  nothing much
can be done about it until the XFree86 team is made aware of new PCI ID's.

output of `lspci -vn`

Comment 10 Bill Nottingham 2001-05-02 18:29:25 UTC
This is solely a kernel agpgart issue. Dunno why it's assigned
to X.

Comment 11 Mike A. Harris 2001-05-02 18:41:10 UTC
Ok, the 0641 pci id is in kudzu already.  It must have been added after
RHL 7.1 was released...

I looked into the XFree86 code and I do not see any sane way of working around
this problem inside XFree86.  If the above workaround works, please use it for
the time being.  As far as I am concerned, this is a hardware/kernel issue, not
an XFree86 issue.

Whoops.. looks like we had a mid air collision there bill..  Reassigning to
