[LinuxBIOS] Linux can't run.

[Feng, Libo]

Hi, all.

We adapted LinuxBIOS for Broadcom Explosion based on Blast LinuxBIOS. It runs well in LinuxBIOS phase, but in Linux phase, there are some problems. It seems the hard disk can't be found. Anyone has the same problem? The attached is the log.

Best Regards <<explosion.log>>

Your interrupts are flat out wrong. Is it the table or some aspect of
hardware setup? How did you generate the mp table? Could that be the
problem?

You need to see what's going on with interrupts.

thanks

No, the hard disk was found (Maxtor 6E040L0). But no interrupt for this IDE 
controller device? -> "hda: lost interrupt" there is no answer.
Recompile your kernel with DEBUG macro defined in "arch/i386/pci/pci.h".
Run this new kernel with kernel parameter "irqpoll" and check your interrupt 
routing...

Hi, Mr. Ron Minnich,

Do you mean the IRQ table? We use the irq_tables.c under Broadcom/blast. We just thought Explosion has the same interrupt routing with Blast. We will try a new IRQ table generated by getpir utility.

Thanks.

please try to use latest kernel, and fix your mptable in LinuxBIOS
according to your schematic and chipset data sheet about irq routing.

Hi, Mr Lu,

Can we boot Linux with the propriety BIOS and then run getpir utility to get irq routing? We don't have the Explosion schematic.

with smp enabled only mptable is used if acpi is not there. irqtable
is only usefull for peer root bus discovery.

you could get Explosion schematic under NDA.
