i3 3217u Speedstep not correct

[dpunx]

Hi!

I read about this problem but I can't resolve it.

In the Beta branch the ivi brydge.cfg have the correct states: i3-3217U,17,800,1800,0,2,4

but all the time the ssdtprgen beta say (1200-1800) and I need other state (generate x7, this CPU is x8). (I modify the .sh to work with beta channel and no way >.<)

And if I use ./ssdtPRGen.sh -p i3-3217U -lfm 800 -w 0, works at 800Mhz all the time, with 1, kp.

Thanks for this great job.

If ssdtPRGen.sh shows 1200-1800 then the data is not ok or you are not using the Beta.

Command line option -w need to be set to a non zero value for Ivy Bridge processors.

Quick PM guide for cpu 3217U on Sierra:
1.Kernel patch to enable XCPM: http://www.insanelymac.com/forum/topic/319035-ivy-bridge-xcpm-kernelpatch-for-1012/
2. SMBIOS macbookpro 10.1
3. in Clover drop SSDT CPUPM and CPU0lst. Deselect Generate P state + C state, deselect C state, a good guide is here: https://www.tonymacx86.com/threads/mavericks-native-cpu-igpu-power-management.128926/
5. Reboot. Check XPCM is enabled sysctl -n machdep.xcpm.mode in terminal. Should be 1
4. generate SSDT https://github.com/Piker-Alpha/ssdtPRGen.sh. with XPCM 1 argument
5. add new SSDT to CLover (+ Clover plist in SSDT order) folder and rename to SSDT-3.aml (replaces the native one). You can keep the other 2 SSDT (0 and 1). Discard the ones with X.
