How to use it?¶
efifb does not have any kind of autodetection of your machine. You have to add the following kernel parameters in your elilo.conf:
Macbook : video=efifb:macbook MacMini : video=efifb:mini Macbook Pro 15", iMac 17" : video=efifb:i17 Macbook Pro 17", iMac 20" : video=efifb:i20
Don’t map the framebuffer write combined. This can be used to workaround side-effects and slowdowns on other CPU cores when large amounts of console data are written.
