>Description:
FreeBSD 4.0 is missing device ID support for certain devices on the
EpoX 7KXA AMD Athlon motherboard.
>How-To-Repeat:
Install FreeBSD 4.0 on a EpoX 7KXA Athlon system.
>Fix:
Here's the "fix" (still haven't found out how to correctly ID the
Host-to-PCI Bridge) in /usr/src/sys/pci/pcisupport.c add:
case 0x83911106:
return ("VIA 82C686 PCI-PCI (AGP) bridge");
Before:
pcib0: <Host to PCI bridge> on motherboard
pci0: <PCI bus> on pcib0
pcib2: <PCI to PCI bridge (vendor=1106 device=8391)> at device 1.0 on pci0
pci1: <PCI bus> on pcib2
After:
pcib0: <Host to PCI bridge> on motherboard
pci0: <PCI bus> on pcib0
pcib2: <VIA 82C686 PCI-PCI (AGP) bridge> at device 1.0 on pci0
pci1: <PCI bus> on pcib2
If someone can point me out how to ID the Host-to-PCI controller, I'll
submit a ID fix for that too. Not sure why the pcib device skipped from
0 to 2, but I'll deal with that as it comes along.
Detects every other 82C686 device just fine however:
isab0: <VIA 82C686 PCI-ISA bridge> at device 7.0 on pci0
atapci0: <VIA 82C686 ATA66 controller> port 0xd000-0xd00f at device 7.1 on pci0
chip1: <VIA 82C686 ACPI interface> at device 4.4 on pci0
