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
Accepted options:
nowc 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.
