From 333176e5d3b77da6e49a1ddd868a180e6d878e20 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Wed, 7 Sep 2016 22:10:57 +0200 Subject: i945/gma.c: Generate fake VBT This generates a fake VBT for the Intel i945 graphic device. i945 supports both the mobile chipset 945gm (calistoga) and the desktop chipset 945gc (lakeport), which is why a VBT with a different id string needs to be created for each target. The VBT id string is obtained from the vbios blob in the following way: "strings vbios.bin | grep VBT".
