Just did this - I used ssdt-PRGen.sh previously. I now seem to have less states there before. Is this normal? Running Skylake Core i3-6100

Edit: Above I was booting with my GT 710 as my display... here is the tail end I get when using SSDT-XCPM.aml when using the iGPU (HD 530):

Pstates observed will depend on how long you monitor and the variety of tasks you do while monitoring.
It is random sampling.

The more samples you take and the more varied the conditions (CPU load) under which the samples are taken, the more likely all values will be seen.

Ok, so I let it run for a bit - ran Geekbench and CineBench, now I'm seeing this:

Code: 
CPU P-States [ (8) 9 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 ]
iGPU P-States [ 2 5 7 10 11 12 13 14 (15) 16 17 18 19 20 21 ]

I also have the following .aml files installed (I also have a GT 710 I installed that I use sometimes):
Code: 
HD530-SSDT-HDMI-HD530.aml
SSDT-PluginType1.aml           
HD530-SSDT-HDEF-HDAS-1.aml
Nvidia-SSDT-HDMI-NVIDIA-PEG0.aml
SSDT-XCPM.aml

I think that means everything is working, yes?

Finally, should I be at all concerned about this output that I see in my AppleIntelInfo.dat"
Code: 
p1 out of range
ref out of range
fp select out of range
pipe A dot 0 n 59 m1 43 m2 18 p1 1 p2 14
p2 out of range
p1 out of range
ref out of range
pipe B dot 0 n 59 m1 59 m2 18 p1 1 p2 1

No need to rename ssdts.
SSDT-PluginType1.aml and SSDT-XCPM.aml are the same, remove one.
Rarely does combining two methods result in success.

No. This is just info on IGPU registers if one (developer) was interested.

Oh I see! I wasn't trying to combine two methods...I was looking at post #1, requirement #3, and interpreted that as needing PluginType1. That wasn't clear to me at all!

I haven't fully caught on to your "shorthand" - I know you've been doing this a loooong time and you know it so well, I feel like I need two more words per instruction :) I'm willing to climb the curve though...sometime just feel like a need a decoder ring.

Thanks so much for all of your work.

Installation, step 6.
Installation always satisfies all requirements.

Maybe you should rename SSDT-XCPM.aml to SSDT-PluginType1.aml to avoid confusion.
Given my SSDT-PluginType1.dsl has existed for more than a year, it might not be a good time to introduce a new name for the same thing.
 
Well thanks. Instruction is not friendly but anyway.
But what is the benefit of this method comparing to usual generated ssdt?

Remember, these are just words. We can't tell how he intends them or is stating them, so it is best not to "assume" any emotion. ;)
