Camera / bluetooth not working on yogamsc branch about t480-opencore-hackintosh HOT 22 CLOSED

@EETagent It seems that you copied my config from the X1C6 but it differs from the T480. F.e. S03 is internal and SDCard on the T480 because the T480 only has one TB-port.

Edit: proposed my config in #58

from t480-opencore-hackintosh.

No _UPC to XUPC rename ...

Will fix that and report back

from t480-opencore-hackintosh.

Webcam, Bluetooth and SD Card finally works! Thanks @benbender for all your help

from t480-opencore-hackintosh.

Hi @Charlyo

Thanks for testing experimental branch. I actually did not test webcam and Bluetooth since moving to SSDT-XHC, Bluetooth tray icon on Big Sur is not crossed out when unavailable unlike on Catalina so this change went undetected :) I already edited draft's false description. For now you can remove this patch and add USBMap/USBPorts back.

@benbender

HS08, HS07 and SS03 are undetected and neither of them works. How we can help to solve this?

Current HS08 config looks OK to me

0xFF - Port is enabled
0xFF - Internal connector type
Zero, 
Zero

from t480-opencore-hackintosh.

Thanks for the update @EETagent!!

Actually, if you think it through, only the "internal" ports fail.

Thanks @benbender,

sadly the situation has not changed. These 3 USB devices still does not work.

from t480-opencore-hackintosh.

A bit more info would be nice :) IOReg-dump? Logs? Is the SSDT applied? Rename for _UPC to XUPC in place?

PS: The SSDT itself and those devices are working as I'm running it right now on my T480.

If your config.plist from the YogaSMC-branch is complete, you are missing the needed patch:

This patch renames all USB-port-definitions in ACPI and redoes them. Today I refined my XHC-SSDT for the X1C6. It may be worth to adapt those changes. This patch may need adaption for the table-length to get applied.

For the future: please check if patches you adapt from me are cleanly applied. In this case they can't be without that patch as the _UPC-definitions collide. Check with a search for AE_ in log show --last boot.

It does not seem so ( With _XUPC rename in place )

from t480-opencore-hackintosh.

You are patching a SSDT. This is different from patching DSDT as it needs the correct Table-signature and length to be applied because there can (and will) be multiple SSDT's on the system. Both values can be found in the header of the SSDT to be patched. View the original XHC-SSDT with MacIASL and adapt the patch accordingly. As said above, the patch is taken from my X1C6 as I only have that at hand.

Additionally, grep'ing for AE_ only shows that there are errors. To see the message, grep after AppleACPIPlatform in the logs. The actual error-messages are below the lines starting with AE_.

PS: I urgently need to do a writeup on how to do basic ACPI-debugging :)

Yes, that would be great :)

from t480-opencore-hackintosh.

As I said - The patch isn't applied because OpenCore can't find the table.

				<key>TableLength</key>
				<integer>6103</integer>

Probably only the length needs to be adapted. Please switch the value with the one found in the original SSDT for the T480 in MacIASL.

Length replaced, SSDT still does not run

@EETagent have you changed OemTableId to the actual file one?

Well, no. Currently there is ProjSsdt, will replace it with _XHC

from t480-opencore-hackintosh.

Not sure if necessary, just felt weird (at least to me).

Rename still does not apply.

Thats the length of your SSDT, not the original. The original is ProjSsdt as @Charlyo said and should be longer.

I am idiot, will fix it immediately

from t480-opencore-hackintosh.

OK, so length of ProjSsdt is 5692

from t480-opencore-hackintosh.

@Charlyo Fixed in 4ef5625

Please try and report back

from t480-opencore-hackintosh.

Working perfectly on last commit!
