macOS Native Discrete GPU Power Management

[bebuxo]

Hi, i'm on a real mac and i cant load AppleGraphicsPowerManagement.kext because i've the MacbookPro6_2.plist removed from IOPlataformPlugin.kext in order to make the machine somehow usable due to a faulty temp sensor. This means i will never get full performace from my discrete graphics card right? Is there any way i can ignore the sensor and having both kexts loaded to get full performace?

Thanks in advance

No. Three choices: fix sensor, patch code or do nothing.

hey, what do you mean with patch code? what do i have to do exactly

No "open" source code for the kext.
Decompile the binary, read the assembly code to figure out where the sensor code is, determine exactly how the sensor code works and patch out the "bad" code to "make the machine somehow usable."

"real mac," off topic

Native dsdt does not support discrete graphics, WhateverGreen does not recognize the problem
Install ssdt_hdmi-nvidia-PEG0.zip to EFI/CLOVER/ACPI/patched/
Restart, reply with new files.

@toleda
Thank you for taking the time checking out the issue, Although it didn't show up, but the 580X sees working fine with acceleration. So, I was less worry about it at the moment. I was thinking the GPU was part of the reason caused the Disk eject issue(while sleep wake). but it might not be, it could be something else related.
