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 <yinghailu(a)gmail.com&gt;: 

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.

 Hi YH,

 Thanks again for your help.

 Now I can active all devices in my LinuxBios, it almost done except
VGA 
 function.

 I appended a 36k VGA option rom to LinuxBios, and enable Options about
VGA.
 And I got the halt_sys message:

 PCI: 04:02.0 init
 rom address for PCI: 04: 02.0 = fff80000
 copying VGA ROM Image from 0xfff80000 to 0xc0000, 0x9000 bytes
 entering emulator
 halt_sys: file
/home/vincente/LinuxBIOS/LinuxBIOSv2/src/devices/emulator/x86emu/ops.c,
 line 4387 
 PCI: 01:04.0 init

 then, I can see something output, but the output is like snow screen
and I
 can't read anything.
 I think it is working in the wrong mode.

 When I made a blind type 'root' and password, I can login the Linux,
and 
 then the screen became clear. (work fine)

 I wonder how to fix the problem? is the halt_sys message normal ?

 I also got another question, could it possible boot to MS-DOS
floppy/USB 
 disk.
 The MS-DOS needs a lot INT function in BIOS, does LinuxBios able to
support
 it?

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.

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.
