Re: [LinuxBIOS] New guy in LinuxBios

Hi,

 

My target board is similar to Tyan s2882, I base on s2882's code to fit my target board.

 

My target board also got an onboard Intel 10/100 NIC, and I assign the irq like s2882 done.

        printk_debug("setting Onboard Intel NIC\n");
        static const unsigned char slotIrqs_8111_1_8[4] = { 9, 0, 0, 0 };
        pci_assign_irqs(bus_8111_1, 4, slotIrqs_8111_1_8);
        write_pirq_info(pirq_info, bus_8111_1,(4<<3)|0, 0x1, 0xdef8, 0, 0, 0, 0, 0, 0, 0, 0);
        pirq_info++; slot_num++;
 

It can works fine on unique processor platform, but when I boot into smp kernel it's interrupts is not going.

Is it possible cause by IO-APIC ??

 

 

 

The other question, my VGA still has snow screen when linuxbios booting,

even I moved the CPU init before other pci device init call.

But after I login the system, it will become clear.

following is part of my log....
