Add graphics memory hole to e820 map

Reported by: stepan Owned by: stepan
Priority: major Milestone:
Component: coreboot Keywords:
Cc: Dependencies:
Patch Status: there is no patch

Description

Memtest86 is reporting memory errors because it is trying to use the a0000 area in LinuxBIOS. This area should be marked as unusable or reserved in the e820 map.

Erm,.. where's the e820 map created? ;)

  • Owner changed from somebody to stepan

The e820 map is generated from the coreboot table memory map by the boot loaders (eg. FILO, GRUB2, SeaBIOS).

We started putting more than just RAM areas in there, but I think there's more to be done.

We do have a mechanism to cleanly do this for UMA architectures now. Check i945/kontron 986lcd-m for an example.
