Understanding PCI IRQ MP output...
Posted: Thu Sep 30, 2010 6:39 pm
Hi!
My MP output gives me 8 similar entries for the PCI IRQ configuration. The I/O Interrupt Assignment Entries that confuse me are:
Bus:0 Dev:8 int_A I/O INTIN:0Bh
Bus:0 Dev:9 int_A I/O INTIN:0Bh
Bus:0 Dev:10 int_A I/O INTIN:0Bh
Bus:0 Dev:11 int_A I/O INTIN:0Bh
Bus:0 Dev:12 int_A I/O INTIN:0Bh
Bus:0 Dev:13 int_A I/O INTIN:0Bh
Bus:0 Dev:14 int_A I/O INTIN:0Bh
Bus:0 Dev:15 int_A I/O INTIN:0Bh
Now I am considering two things:
1º Error in the MP parse/print routine
2º PCI IRQs are not configured yet
While not discart it at all, I doubt about the first, becouse the same routine prints correctly the ISA IRQ entries.
All the devices and functions I find during the PCI scaning, are not above 4-5 in total(depending on hardware configuration). And there is only bus:0 in the system.
Has anyone got similar output?
