Could not get ACPI device for PCI provider

[ghost]

Describe the bug
The trackpad stopped working after I added an extra M.2 drive, but it still didn't work when I removed the drive. It works in Windows always nevertheless. When in verbose boot, there are two lines, one is VoodooI2CPCIController::pci8086,a369 Could not get ACPI device for PCI provider, and the other one is the same but just for 8086,a368. The machine has two I2C controllers, one is I2C0 which is for the touchscreen optional assembly that I don't have, and I2C1 is for the dual pointing device. Many thanks!

This really looks like a specific issue with your ACPI as from what I can from your IO Registry dump, VoodooI2C is not finding any I2C controllers. As I do not have your EFI here, I can only speculate as to what the problem is, please upload a copy of your EFI folder.

Additionally, how are you patching in the GPIO pin?

Hi,

Thank you so much for your reply! My EFI folder can be downloaded from here.

I've patched it via 0x1b, which i believe should be the correct calculated value. Both GPIO and polling mode worked very well before I installed that cursed M.2 drive into my system. Thank you again!

Edit: I injected the DSDT via OpenCore because otherwise the basic tables won't load in macOS. So the I2C patch is also integrated into the DSDT...

That would be your problem. By adding a new device (M.2 drive), your ACPI device paths most likely changed. That is why you should hotpatch. For now, you will need to take a new dump of your DSDT and re-patch it (I highly advise against this).

As this is a configuration issue, please use Gitter for further support.

THANK YOU!!!!!!

You're absolutely correct. The memory address in DSDT changed after I installed the drive. After I compared the changes and modified the patched DSDT, everything backs to work. Thank you sooooo much and fixing this -- and finally realizing the cause of this -- definitely made my day. Can't appreciate it more!!!

No worries @lulujyc, enjoy your hack :)
