Re: Geode GX1 and IRQ tables

Good point. I did not know about ACPI. Ok, looking through the source, I don't see ACPI in the gx1 code. So I presume that this means that LinuxBIOS doesn't provide ACPI support in the case of the Geode. Would I be able to test if Linux 2.6.10 is able to parse the normal BIOS' PIRQ table by booting linux with acpi=off? If it does work at that point, then I could assume that the area to be fixed would be the PIRQ table generation in LinuxBIOS. If not, then it'd be time to examine the kernel's pirq code. I'm still somewhat confused though. At the point that LB calls the kernel, shoudn't LB have used the IRQ table values to set the PCI config space registers to write IRQ values to the PCI config registers and such? And if that were done, Linux would not need to parse a PIRQ table, yes?

That's odd. My understanding might be lacking. I think the PIRQ table parser in 2.6.10 seems to work because it works when I use the normal BIOS. Therefore allowing the inference that 2.6.10 can read the table that was generated by the normal BIOS, right? What do you think? I'm now reading through the Alan Cox/Christer geode PIRQ discussion to see if I missed something. --- "Ronald G.
