HPET Enabler Project

[compu829]

Hey everyone! In attempting to solve some minor issues involving my T60P hackintosh, I know that one of the major issues with AppleIntelCPUPowerManagement.kext is the "Failed to get a HPET" error. I stumbled across the following link http://www.opensubscriber.com/message/linu...rg/6656514.html From what I gather, This driver code will force the recognition of HPET, overriding hat part of the DSDT. My ultimate goal is to see what happens if we can get AppleIntelCPUPowerManagement.kext working. I wonder if it will automagically take control of SpeedStepping and the like because real Macs support ICH-5 and up chipsets, which all use HPET.

 

This is my first attempt at a driver, so any help is always appreciated!

This is unnecessary. We have a direct replacement for AppleIntelCPUPowerManagement now called IntelEnchancedSpeedStep.

Disable the original Apple one using NullCPUPowerManagement.kext or Disabler.kext and drop this new one in.

It is no wrongdoings in trying. But you will need the SMC, as Apple uses the thermal sensors on SMC. But if this is first time attempting to write in the kernel space, you better be patient. You will run into several brickwalls, especially in a project like this, as everything you have to write must be tightly integrated to the kernel. It is AppleHPET that you first need to rewrite. The rest should work as it self, and something to fake the SMC. Easier is probabaly to rewrite the platform expert.
