HELP WITH SPEEDSTEP

[ruorbe]

I've made my own DSDT and I got almost everything working smoothly

Shutdown, sleep, audio, etc.

but I cannnot get speedstep working I only get 2 steps.

I've tried ssdt, generate P and c states and both without any luck.

I'd really appreciate your advice.

Thanks.

Double check this time NullPM isn't loaded and still only 2 states (minimum and maximum)

Changed ACPI_SMC_PlatformPlugin from macbook pro 8,1 and it works perfectly.

Thanks
