[SeaBIOS] SeaBIOS hang with VGA option ROM

[Timothy Pearson]

All,

I have a board here that uses an XGI Volari Z9s integrated graphics
device. The board boots under coreboot and loads Linux, but if I add
the appropriate VGA option ROM (extracted from the vendor BIOS) SeaBIOS
hangs:

SeaBIOS (version rel-1.7.5-150-g301dd09-20150126_124858-apollo)
Found mainboard ASUS KFSN4-DRE
Relocating init from 0x000e6fe0 to 0x3ff95800 (size 42816)
Found CBFS header at 0xfffffc80
CPU Mhz=2311
Found 26 PCI devices (max PCI bus is 05)
Copying MPTABLE from 0x3ffe0400/3ffe0410 to 0x000f1550
Copying ACPI RSDP from 0x3ffe1400 to 0x000f1520
Copying SMBIOS entry point from 0x3ffec800 to 0x000f1500
Using pmtimer, ioport 0x2008
Scan for VGA option rom
Running option rom at c000:0003

The Volari graphics initialise and work properly once Linux has booted
and loaded the appropriate device drivers. For now I have been using
SGABIOS for VGA emulation, however I would like to see the native VGA
work on boot.

Any ideas?

Thanks!

It will likely be hard to figure out why your vendor vgabios is
hanging. It's possible something in seabios is causing it to get
confused, but it's also possible something during the coreboot
initialization is confusing it.

I suggest increasing the SeaBIOS debugging level to 8 and see if it
reveals any further information.

Running option rom at c000:0003

So, no additional information. You could try increasing the debug
level to 99 just to see if irqs are still on (and if so, to see where
the pc is when irqs are hitting). However, unless you have access to
the vendor vgabios code it's very difficult to guess what's confusing
it.

BTW, did you make sure all of the following are disabled in coreboot:
CONFIG_VGA_ROM_RUN, CONFIG_PCI_ROM_RUN, CONFIG_ON_DEVICE_ROM_RUN

If coreboot supports native vga init for your board, you could try
using seavgabios and skip the vendor vgabios.

Another approach would be to see if you can get get the vga bios to
run in some emulator (such as xorg's x86emu, coreboot's emulator,
qemu, etc) and then try to figure out what's different.

Please keep the mailing list on the CC.

Dear Timothy,


thank you for reporting this issue to the SeaBIOS mailing list.

The Volari graphics initialise and work properly once Linux has booted

SGABIOS for VGA emulation, however I would like to see the native VGA
work on boot.

Is coreboot able to successfully run the Video BIOS? Just add it using
the coreboot Kconfig menu.


Thanks,

No, coreboot hangs as well:

As everything else works I probably won't spend much more time on this,
but I am willing to test if anyone has ideas on how to fix the issue.

I take it coreboot cannot natively initialise XGI Volari devices?

Thanks!
