This kext powers off unused PCI devices. Useful for powering off unused dGPU or NVMe, thus better battery life.

• This works perfectly for me, but I haven't tested this whatsoever for any other builds or PCs. So this will be buggy.
• This might sound non-responsible, but this kext is provided as-is. No support provided. Sorry for saying this, but please think this kext as proof-of-concept.

​

# What this program does:

This kext disables and powers off speicifc PCI slot. To be exact, this program puts PCI device to D3 (sleep) state with the same method I've contributed to VoodooI2C.
