Hi and welcome to coreboot,
First of all please use coreboot container: https://hub.docker.com/r/coreboot/coreboot-sdk/ You are guaranteed to have no errors during compilation.
DVMT... this terminology is so confusing. I think it refers to the UMA memory which is configured here for x220:
https://github.com/coreboot/coreboot/blob/master/src/northbridge/intel/sandy...
You can change that by changing the gfx_uma_size parameter in CMOS configuration utility - nvramcui. It is a payload that modifies the CMOS based runtime options.
Regards, Michał

Hi,
I'm new to coreboot and this list, so please forgive and tell me if I'm doing something wrong.
I've successfully compile coreboot and flash it to a Lenovo x220. I tried seabios and tianocore as a payload and it works. So strange compile errors as I'm used to when I compile an opensource project. So, _bravo_.
What I need now is to be able to set the graphic preallocated memory. Usually in bios, it's "DVMT pre alloc" or something. I know it's possible on this platform because the unlocked bios can do it.
Could anyone point me in the direction ?
Thanks,
Jief
