commit ba2e740420d9d7f093933f5f218504c98211d58a Author: Patrick Rudolph siro@das-labor.org Date: Mon Dec 28 14:03:15 2015 +0100
mainboard/lenovo: add cmos layout for hybrid graphics
Add cmos layout vga_primary_is_peg and vga_secondary_powersave.
vga_secondary_powersave defaults to true and must remain true ! Using two GPUs at the same time isn't supported at time by the hybrid graphics driver and will result in black screen.
Toggling vga_primary_is_peg allow switching between integrated and dedicated GPU using nvramtool.
Tested on Lenovo T520 using Nvidia NVS 5200m.
