Enable onboard VGA on the MS-6178 (i810 chipset) board (trivial).
Tested on hardware with the patch from r4398 and works fine as soon
as Linux boots (no VGA in FILO for some reason, will investigate).
In order to make the 'i810.vga' VGA blob from the vendor BIOS work
you have to make the check for PCI device ID mismatches non-fatal
(for now) in the src/devices/pci_rom.c file like this:
Index: src/devices/pci_rom.c

if (dev->vendor != rom_data->vendor || dev->device != rom_data->device) {
printk_err("Device or Vendor ID mismatch Vendor %04x, Device %04x\n",
rom_data->vendor, rom_data->device);
- return NULL;
+ // return NULL;
}
printk_spew("PCI ROM Image, Class Code %04x%02x, Code Type %02x\n",
The reason is that the VGA blob thinks the proper VGA device ID is 0x7123
whereas it really is 0x7121 on hardware. There are multiple ways to work
around this (there have been many discussions in the past), we'll see which
method will be used in future...
Note: This has been tested against r4393 only for now to make sure there
are no problems because of the recent resource allocator changes, see
http://www.coreboot.org/pipermail/coreboot/2009-July/050486.html.
Tests with trunk will follow.
