I have been trying the get ACPI working on a dual Opteron motherboard. I have used the island/aruma code as a reference. I have built the dsdt.c and fadt.c files from a commercial BIOS with ACPI. With the commercial BIOS I see this message:
PCI: PCI BIOS revision 2.10 entry at 0xfd73f, last bus=143
Looking the 2.6.9 kernel module arch/i386/pci/pcbios.c, it seems to want to make a PCI BIOS call to the PCI_SERVICE entry point.
Not sure if the above message is ACPI related. Can you send the whole log?
You will likely need to rewrite parts of the dsdt since it contains bus numbers etc that might be different in LinuxBIOS
So I’m not sure if you were able to get the island/aruma board to work with ACPI?
yes. it works fine.
Does LinuxBIOS need to support PC BIOS calls?
not for ACPI. ACPI was originally designed to provide a callback free bios interface. Which is a good thing in theory, LinuxBIOS does similar with the LinuxBIOS table.
