PIRQ problems on Geode GX1 board.

Wed Apr 9 20:42:01 CEST 2003

Thanks to lots of great help from Eric on the Etherboot list I have my
system mostly working, except there appear to be some problems with the
PCI IRQ routing stuff.

I ran getpir on the target with its standard bios, and got a good
irq_tables.c, and HAVE_PIRQ_TABLE=1 is set in the Config.

But this line is troubling:
Verifing priq routing tables copy at 0xf0000...failed

Any idea why this is failing?

When the kernel is loading I get the following complaint:
PCI: No IRQ known for interrupt pin A of device 00:0d.0. Please try
using pci=biosirq.

I'm also hoping this be why my IDE does not appear to be working.

I don't imagine it is the memcpy call that is bad, so I'm guessing there
is a problem with my memory setup.

Any suggestions?

Thanks,

Joey Nelson
