Fwd: PCI ID conflicts between Cyrix, NSC and AMD Geodes video devices
Upstream confirmed exactly what PCI ID correspond to what and this
clearly shows that current Cyrix and NSC drivers in Debian not only
generate false positives, but also try to pass IDE controllers as
video devices.
To answer Brice's question, 100B0504 corresponds to late GX1 hardware
supported by the NSC driver only.

10780002 -> Cyrix CS5530 IDE
10780104 -> Cyrix CS5530 Video

10780104 -> Cyrix CS5530 Video (IP Transition to NSC)
10780504 -> UNKNOWN
10780104 -> Cyrix CS5530 Video (IP Transition to NSC)
10780030 -> UNKNOWN
100B0104 -> UNKNOWN (NSC CS5530 Video IP Transition to NSC
from Cyrix)
100B0504 -> NSC SCx200 Video
100B0104 -> UNKNOWN (NSC CS5530 Video IP Transition to NSC
from Cyrix)
100B0030 -> UNKNOWN (IP Transition to NSC)
/usr/share/xserver-xorg/pci/geode.ids
10222081 -> AMD Geode LX Video
It appears there are a couple repeat PCI IDS in the list. The values
that state UNKNOWN are not registered in the Linux PCI ID Repository.
Although it is "brute force" the values that are UNKNOWN should
probably be pulled. I'll leave that decision up to you as the
maintainer what needs to happen with these.

Hello everyone,
While working on solving Debian and Ubuntu packaging issues, we
noticed that the X.org drivers currently packaged there cover a series
of PCI ID that might cause conflicts between different Geode drivers.
Also, we noticed vendor+device ID combinations that might have never
existed and yet being claimed as supported.
Could someone in the AMD team confirm or infirm whether the following
ID numbers are valid for each driver and whether any ID number is
missing?
/usr/share/xserver-xorg/pci/cyrix.ids
10780000
10780002
10780104
/usr/share/xserver-xorg/pci/nsc.ids
10780104
10780504
10780104
10780030
100B0104
100B0504
100B0104
100B0030
/usr/share/xserver-xorg/pci/geode.ids
10222081
Thanks in advance for your help!
Best Regards,
