Subject: Who is stomping PCI config space?
Date: Thu, 3 Mar 2005 14:03:43 -0500 [thread overview]
Message-ID: <9e4733910503031103552514b9@mail.gmail.com> (raw)
I have two video cards:
PCI Rage128
AGP Radeon
X is loaded on the Rage128 on VT7
X is not configured to support the radeon
I switch to VT1 and load radeonfb
This works fine.
Now I switch to VT7 and dump PCI config space for the radeon
[root@jonsmirl 0000:01:00.0]# hexdump config >/foo
[root@jonsmirl 0000:01:00.0]# diff /foo /bar

Somebody is changing PCI command from 83 to 80 and disabling my
radeon's memory and iospace. Who is doing this? It has to be X since
it doesn't happen if I switch to VT6 or VT8.
Why is X mucking with a card it doesn't have a driver loaded for?
Where is this happening in the X code?
