Re: [LinuxBIOS] New guy in LinuxBios

[Lu, Yinghai]

In the MB Config.lb

The device apic_cluster 0 should be put before other pci devices

Hi,

Excuse me....

I don't know how to move the CPU init before other pci device init
call....

sorry.

I have tried to find it, but .... :(

2006/6/26, yhlu :

the snow screen only happened when I was debugging the onboard VGA
support.
So i move the CPU init before other pci device init call. That is 
something related to mtrr setting around [0xa0000-0xb0000) the font
buffer.
the halt_sys display is normal...it means the vga option rom is
executed successfully.
you can use filo in etherboot to boot from usb stick.

Dear YH,

thanks for your reply.

you are my light in the dark ...

I'm trying to modify dev_initialize() in devices/device.c ...
how fool I am.

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.

[root@iSCSI h412]# cat /proc/interrupts

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....

you need to update the entry in mptable.c for your eth0. try to read
the schematic to figure out how the io apic is conntected.

Yeah, it works now.

Thanks a lot.

How about the snow screen issue?
Do you have any idea?
