What should be the SMBIOS? Should I let Clover decide this or use something like MBP14,3?

 

Your choice really... 

I have used iMac14,1, iMac14,2, and iMac17,1...

There is also the new iMac18,x...

In this case, I think it's better for us to follow Apple, not enabling HWP for now on desktops.

Ah yes... Just adding related power features.

It won't be too complex I guess, with the help of some kexts that help us write corresponding MSRs.

 

(I don't own any Skylake+ desktops to test though...)


IMO it must bring negative effects to performance without SpeedStep. HWP can be just a small part of PM, it doesn't really matter. :)

 

No special kext necessary for HWP enabling (including after sleep/wake).  The code is already in the kernel/X86PlatformPlugin.

Agree probably best to avoid HWP on desktop (even though it works), as Apple is not using it.  But it is still interesting to experiment with it...

Well, I've checked it earlier today, the same on iMac18,x and iMac19,1, no HWP support in their FrequencyVectors.

So thing is. Why Apple don't enable HWP for iMac...

They probably find it can affect performance negatively on desktops or has no positive effect at all...  I have seen the same...

Point is though... easy to add HWP to your chosen SMBIOS... and then it will be restored across sleep/wake cycle.

Yes... I've also done the same thing a little bit earlier. (http://www.insanelym...-5#entry2368367)

But, has Apple really enabled HWP for their real iMac? Unfortunately I don't have such models and therefore I can't check it. IMO, it's very likely that, Apple doesn't enable HWP for iMac.

 

iMac17,1 is not enabled by Apple provided plists.

I haven't checked the other new iMac plists.

You can check easily with freqVectorsEdit.sh.

I saw iMac17,1, iMac18,x and even iMac19,1 (the coming iMac Pro) have no "hwp" power feature in their FreqeuncyVectors, unlike MacBook(Pro).

Maybe just like @Slice said, the mechanism is a little bit different...

 

It is why I added HWP to my iMac17,1 X86PlatformPlugin injector kext.
