Dear coreboot folks,
why does AGESA need the Video BIOS hook for Family 15tn (Trinity) and
Family 16 (Kabini)?
$ more src/northbridge/amd/agesa/family15tn/fam15tn_callouts.c
[…]
AGESA_STATUS fam15tn_HookGfxGetVbiosImage(UINT32 Func, UINT32 FchData, VOID *ConfigPrt)
{
GFX_VBIOS_IMAGE_INFO *pVbiosImageInfo = (GFX_VBIOS_IMAGE_INFO *)ConfigPrt;
pVbiosImageInfo->ImagePtr = cbfs_get_file_content(
CBFS_DEFAULT_MEDIA, "pci"CONFIG_VGA_BIOS_ID".rom",
CBFS_TYPE_OPTIONROM);
/* printk(BIOS_DEBUG, "IMGptr=%x\n", pVbiosImageInfo->ImagePtr); */
return pVbiosImageInfo->ImagePtr == NULL ? AGESA_WARNING : AGESA_SUCCESS;
}
Looking through
src/vendorcode/amd/agesa/f15tn/Legacy/Proc/agesaCallouts.c
I do not see what this is needed for.
Thanks,
Paul
