[Guide] Native Power Management for Laptops

[Jingu]

Okay thanks. If HWP is set up correctly, I may need to fine tune the FrequencyVectors. But, for now I only know how to use Piker Alpha's script to change Low Frequency Mode idle from 1300 MHz to 800 MHz.

Hi, I've got native power management working on my HP Spectre x360 with HWP enabled, but I still see much higher power consumption on intel power gadget (roughly twice the wattage) at any given frequency. AppleLPC kext loads, as does X86PlatformPlugin. Patched my frequency vectors for lower idle speeds, still not much luck. Anything I could be missing? Haven't noticed any cpu-intensive applications either. Problem Reporting files attached.

As per post #1, you should test pstates with AppleIntelInfo.kext.
Also, if you don't like HWP, don't use it (use non-HWP SMBIOS).

To be clear, I do want to keep HWP enabled, I'm just surprised to see such comparatively high power consumption on OS X (don't see same issue on my desktop hackintosh) and I'm unclear what I'm doing wrong.

To be clear, I do want to keep HWP enabled, I'm just surprised to see such comparatively high power consumption on OS X (don't see same issue on my desktop hackintosh) and I'm unclear what I'm doing wrong.

Are you finding that it is often stuck at x31?
Maybe you have something using CPU resources (background task, misbehaving kext, etc).
Check in Activity Monitor.

For a bit there I was having a bug with that, I believe after patching frequency vectors kernel_task will occasionally encounter a bug and use the CPU at 100%. Fix seems to be removing
ACPI_SMC_PlatformPlugin.kext, although if that fails I'd presume removing frequency vector edits would provide the same fix. Interestingly, it seems my CPU does stay in turbo mode (even when idling to non turbo frequencies) since changing the frequency vectors for only non turbo mode will not effect the minimum CPU frequency.

ACPI_SMC_PlatformPlugin.kext has nothing to do with FrequencyVectors. FrequencyVectors are used by X86PlatformPlugin.kext only.

Oh yeah I know, I mean in reference to the runaway cpu usage I was experiencing after patching my frequency vectors. I'm reasonably certain that the kernel_task issue was caused by patching X86PlatformPlugin though. It's a strange issue and I haven't seen anyone else with it.

Easy way to isolate it.
Remove any such patches...

Replaced both ACPI_SMC_PlatformPlugin.kext and X86PlatformPlugin.kext with stock, updated problem reporting files attached.
Cpu idles higher (as expected), but kernel_task issue hasn't appeared yet.
