Power Management for Sandy Bridge/Ivy Bridge/Haswell/other Laptops

Power Management for Sandy Bridge and Ivy Bridge Laptops

Here is a quick Ivy/Sandy Bridge Power Management checklist:

- patched AppleIntelCPUPowerManagement installed
- SSDT installed to /Extra/ssdt.aml for your CPU (easiest to use ProBook Installer)
- appropriate System Definition (smbios.plist) for your CPU
- DropSSDT=Yes, GeneratePStates=No, GenerateCStates=No
- no rollbacks of AppleACPIPlatform.kext
- no NullCPUPowerManagement.kext (usually implies patched AppleIntelCPUPowerManagement)
- Processor objects declared in Scope (_SB) in DSDT (pretty rare not to have them in OEM DSDT)

Note: For Sandy Bridge PM, it is possible to run a rollback of AppleACPIPlatform.kext but it is discouraged. Watch out for battery manager packages that include a rolled back AppleACPIPlatform.kext.

Note: Running stock AppleACPIPlatform.kext means any DSDT methods that manipulate EC (EmbeddedControl) registers larger than 8-bits will not work and will cause the method to fail. These methods must be patched. Access to such registers is common in DSDT battery methods. Some patches are provided at my laptop DSDT patch repository at: https://github.com/RehabMan/Laptop-DSDT-Patch

RehabMan,

1. Does everything in your checklist still applies if using Clover? Such as
- patched AppleIntelCPUPowerManagement
- appropriate System Definition (smbios.plist) for your CPU
- DropSSDT=Yes, GeneratePStates=No, GenerateCStates=No

2. What do you mean by no rollbacks of AppleACPIPlatform.kext? You mean use AppleACPIPlatform.kext from a previous version of OSX?

Thanks!

The details are different, but all still apply to Clover.

Correct. To clarify, I mean "Do not use AppleACPIPlatform.kext from a previous version of OS X."

Good to know, couple more questions about the detail please


1. DropSSDT=Yes, GeneratePStates=No, GenerateCStates=No

I take the following snip from config.plist of the "Acer Aspire 5750G with Mavericks (10.9) Clover Install Guide" of the forum. In this case, it specify both patched SSDT.aml and DSDT.aml, it also "Generate" both p-state and c-state if I understand correctly. How should we apply "DropSSDT=Yes, GeneratePStates=No, GenerateCStates=No" here?

<dict>
<key>DSDT</key>
<dict>
<key>Name</key>
<string>DSDT.aml</string>
</dict>
<key>SSDT</key>
<dict>
<key>Name</key>
<string>SSDT.aml</string>
</dict>
<key>Generate</key>
<true/>
<key>SmartUPS</key>
<string>2</string>
</dict>


2. Appropriate System Definition (smbios.plist) for your CPU

That should be taken care of by patched SSDT.aml?

Thanks!

SSDT management in Clover is more complex/flexible. If you want to know the details, read the Clover wiki. You might look at the config.plist files provided here for clues: http://www.tonymacx86.com/hp-probook-mavericks/112383-guide-install-mavericks-clover-bootloader.html

2. Appropriate System Definition (smbios.plist) for your CPU

No. Smbios is separate/independent from SSDT. In clover it is controlled via SMBIOS section of config.plist.

Also, there is no patching going on with the SSDT.aml being discussed. It is generated via script.
 
Power Management for Sandy Bridge and Ivy Bridge Laptops

My default Clover config.plist has SSDT Pstate and CState generated, and it did not specify a SSDT.aml file. I do have the AppleIntelCPUPowerManagement pached using Multibeast.

How do I know for sure my CPU PowerManagement works?

I tried DPCIManager and clicked the P-State on the top, the mouse cursor then starts turning forever like this:beachball: .

It is a good idea to read the entire thread related to software you may be using (in this case DPCIManager): http://www.tonymacx86.com/general-help/87342-dpcimanager-1-5-open-beta-6.html#post771931

Tried the workaround of the tool. Thanks!

It appears my Pstate works:

You should probably try with a recent AppleIntelCPUPowerManagementInfo.kext.

DPCIManager is unlikely to show as many states as are actually happening... See: http://www.tonymacx86.com/mavericks...vericks-native-cpu-igpu-power-management.html
