Hello, Stefan
First, the GSOC mid term evaluation comes. Please submit the mentor midterm survey for this "SCSI booting in coreboot" project. The timeline is July 7th to July 14th at 19:00 UTC. Refer to "Survey Information for Mentors with Students Assigned to Them" on http://groups.google.com/group/google-summer-of-code-announce/web/midterm-su... Thanks.
Second, my process and problems:

Hello Stefan,
2008/6/25, Zhang Rui zrfail@gmail.com:
- Where is the entrance call of util/x86emu in coreboot v3?
There are several x86EMU_XXX function exported in e86emu.h. But they are called only in run_bios() in biosemu.c. I placed a printk at the beginning of run_bios() but it seems not executed. How does the codes in util/x86emu used? Where is the entrance call of util/x86emu in coreboot v3? Where should I place the code to extract LegacyBIOS to the memory? Should I write a new function and export it?
Stefan, could you help me with this question? Thanks.
I finally find that in arch/x86/, function pci_dev_init() called run_bios() in util/x86emu. The order is : pci_dev_init -->pci_rom_probe -->run_bios(vm86.c/biosemu.c)
my problem is: in pci_rom_probe, most rom_address is 0 and return NULL; only one rom_address is 0x c0000 but the rom_header->signature is 0 so it also return NULL.
So no run_bios is running.
How can I get run_bios() running and test my code in it?
Best regards.

Here is the output of qemu: [...]
Now I find that there is something wrong with my vgabios-cirrus. I download it from www.coreboot.org by a browser and unzip it to "vgabios-cirrus". But actually it is only 14k. I added ".zip" to the file "vgabios-cirrus" and unzip it to "vgabios-cirrus.bin". And it works now.
But new problem comes up: "Device or Vendor ID mismatch Vendor 0846, Device ec89" So run_bios() is not executed.
Here is related source code: in device/pci_device.c, in function pci_dev_init() rom = pci_rom_probe(dev); if (rom == NULL) return; ram = pci_rom_load(dev, rom); if (ram == NULL) return; run_bios(dev, (unsigned long)ram);
run_bios is called here. But before it is called, there are two "return" statement. And:
in device/pci_rom.c, line 111~116, in function pci_rom_probe() if (dev->id.u.pci.vendor != rom_data->vendor || dev->id.u.pci.device != rom_data->device) { printk(BIOS_ERR, "Device or Vendor ID mismatch Vendor %04x, Device %04x\n", rom_data->vendor, rom_data->device); return NULL; }
it returns NULL here.
Maybe I should clear the code in pci_dev_init() and call modified run_bios() (or another function run_seabios() written by myself) directly? And then I could test my codes in the run_bios().
Best regards. Zhang Rui

Hello, Stefan
First, the GSOC mid term evaluation comes. Please submit the mentor midterm survey for this "SCSI booting in coreboot" project. The timeline is July 7th to July 14th at 19:00 UTC. Refer to "Survey Information for Mentors with Students Assigned to Them" on http://groups.google.com/group/google-summer-of-code-announce/web/midterm-su... Thanks.
Second, my process and problems:
2008/7/6 Zhang Rui zrfail@gmail.com:
Hello Stefan,
2008/6/25, Zhang Rui zrfail@gmail.com:
[...]
I finally find that in arch/x86/, function pci_dev_init() called run_bios() in util/x86emu. The order is : pci_dev_init -->pci_rom_probe -->run_bios(vm86.c/biosemu.c)
my problem is: in pci_rom_probe, most rom_address is 0 and return NULL; only one rom_address is 0x c0000 but the rom_header->signature is 0 so it also return NULL.
So no run_bios is running.
How can I get run_bios() running and test my code in it?
Best regards.
Zhang Rui
Here is the output of qemu: [...]
Now I find that there is something wrong with my vgabios-cirrus. I download it from www.coreboot.org by a browser and unzip it to "vgabios-cirrus". But actually it is only 14k. I added ".zip" to the file "vgabios-cirrus" and unzip it to "vgabios-cirrus.bin". And it works now.
But new problem comes up: "Device or Vendor ID mismatch Vendor 0846, Device ec89" So run_bios() is not executed.
Here is related source code: in device/pci_device.c, in function pci_dev_init() rom = pci_rom_probe(dev); if (rom == NULL) return; ram = pci_rom_load(dev, rom); if (ram == NULL) return; run_bios(dev, (unsigned long)ram);
run_bios is called here. But before it is called, there are two "return" statement. And:
in device/pci_rom.c, line 111~116, in function pci_rom_probe() if (dev->id.u.pci.vendor != rom_data->vendor || dev->id.u.pci.device != rom_data->device) { printk(BIOS_ERR, "Device or Vendor ID mismatch Vendor %04x, Device %04x\n", rom_data->vendor, rom_data->device); return NULL; }
it returns NULL here.
Maybe I should clear the code in pci_dev_init() and call modified run_bios() (or another function run_seabios() written by myself) directly? And then I could test my codes in the run_bios().
I wrote run_seabios() in vm86.c to copy Legacybios to 0xf0000
modify pci_dev_init() in device/pci_device.c to call run_seabios() in vm86.c
Then, at line 224 in arch/x86/stage1.c, before "die("FATAL: No usable payload found.\n");" 1. call run_address(0x000f7ad7); //0x000f7ad7 is the address of post() in LegacyBIOS qemu dies and can not close the qemu window.
2. call run_address(0x000f66e0); //0x000f66e0 is the entry address of LegacyBIOS payload. And I find that 0x000f66e0 is the address of post32() defined in out/rom32.offset.auto.h LegacyBIOS runs correct as if it is the payload.
The difference of post32() and post() is that post32() sets up special idt, gdt and stack. And post32() would call init_dma() before post(). I will try these work manually. I will write another entry in LegacyBIOS which will initialize the LegacyBIOS and then return to coreboot.
By the way, please submit the midterm survay in time. ^_^
Best regards. Zhang Rui

[...]
I wrote run_seabios() in vm86.c to copy Legacybios to 0xf0000
I will write another entry in LegacyBIOS which will initialize the LegacyBIOS and then return to coreboot.
In LegacyBIOS(SeaBIOS), I inserted some code in post.c
void VISIBLE32 post_coreboot() { init_dma(); post(); dprintf(1, "post_coreboot return\n"); }
asm( ".global start_coreboot\n" "start_coreboot:\n" "cli\n" "cld\n" "lidtl " __stringify(0xf0000 | OFFSET_pmode_IDT_info) "\n" "lgdtl " __stringify(0xf0000 | OFFSET_rombios32_gdt_48) "\n" "movl $" __stringify(BUILD_STACK_ADDR) ", %esp\n" "ljmp $0x10, $post_coreboot\n" );
In coreboot, I modified my function in vm86.c printk(BIOS_INFO, "Legacy BIOS copied.\n"); run_address(0x000f66fc); printk(BIOS_INFO, "Legacy BIOS VGA finish.\n");
where 0x000f66fc is the address of start_coreboot() in LegacyBIOS.
The VGA can be initialized by LegacyBIOS(SeaBIOS), but it can not return to coreboot. The qemu meets a fatal error when the post_coreboot() returns.
I think the return address in the stack is wrong. I am trying to figure it out.
Here is the output:

I think the return address in the stack is wrong. I am trying to figure it out.
You moved the stack (by assigning a new value to %esp). So, the return address is not on the stack - it's on the previous stack.

But I tried without "movl $" __stringify(BUILD_STACK_ADDR) ", %esp\n", post_coreboot in LegacyBIOS(SeaBIOS) can not run correctly. I think I should manually set the return address?

Right - seabios needs to be using its stack in order to call 16bit functions. You probably need to save and restore the stack. Completely untested, but something like:
movl %esp, %esi movl $BUILD_STACK_ADDR, %esp ljmp 0x10, $1f
1: calll post_coreboot
movl %esi, %esp retl
However, note that the above wont save/restore the idt/gdt. And again, I'm not sure if coreboot puts its stack/idt/gdt somewhere where seabios may overwrite it.

I used this: "movl %esp, %esi\n" "movl $" __stringify(BUILD_STACK_ADDR) ", %esp\n" "ljmp $0x10, $post_coreboot\n"
and added this at the end of post_coreboot() function: asm( "movl %esi, %esp\n" "retl" );
Then it can return to coreboot correctly. Till the payload(I used no payload here)
But pci_dev_init() is executed more than one time so vga is initialized more than one time in SeaBIOS. A flag variable would be used to run SeaBIOS only once.
However, note that the above wont save/restore the idt/gdt. And again, I'm not sure if coreboot puts its stack/idt/gdt somewhere where seabios may overwrite it.
I am supprised that it just run correctly when return address is set. I supposed to restore the gdt. Maybe the gdt of SeaBIOS and coreboot are the same.
And I want to know where will SeaBIOS write in the memory. Such as the range of bda and ebda?
I think it is time to int SCSI controller, and set the int 13 for it.

That's dangerous because the compiler might use %esi in the post_coreboot() function. If you really want to do this, you should move %esp to %eax and declare the stack pointer as an argument to post_coreboot() and then pass the argument to the inline asm.

I see. I will change this.
