## Finding the ACPI path
|
|
|
|
Finding the ACPI pathing is quite easy actually, first open your decompiled DSDT you got from [Dumping the DSDT](/Manual/dump.md) and [Decompiling and Compiling](/Manual/compile.md) with either maciASL(if in macOS) or any other text editor if in Windows or Linux(VSCode has an [ACPI extension](https://marketplace.visualstudio.com/items?itemName=Thog.vscode-asl) that can also help).
|
|
|
|
Next, search for the `Device (RHUB)`
|
|
|
|
You should get something like the following show up:
|
|
|
|
|
|
|
|
From the above, we can see that the full ACPI pathing for RHUB is `PCI0.XHC.RHUB`. If it's not as clear you can search for what those device paths are for your system:
|
|
|
|
* Finding the PCI path:
|
|
* Search `PNP0A08` (If multiple show up, use the first one)
|
|
* Finding XHCI path
|
|
* Search for `XHC`, `XHCI` and `XHC1`, and yours is whichever shows up.
|
|
|
|
Now with the pathing, you can head here: [Edits to the sample SSDT](#edits-to-the-sample-ssdt)
|
|
|
|
## Edits to the sample SSDT
|
|
|
|
Now that we have our ACPI path, lets grab our SSDT and get to work:
|
|
|
|
* [SSDT-RHUB.dsl](https://github.com/dortania/Getting-Started-With-ACPI/blob/master/extra-files/decompiled/SSDT-RHUB.dsl)
|
|
|
|
By default, this uses `PCI0.XHC_.RHUB` for the pathing. you'll want to rename accordingly.
|
|
|
|
Following the example from above, we'll be renaming it to `PCI0.XHC1.RHUB`:
|
|
|
|
**Before**:
|
|
|
|
```
|
|
External (_SB_.PCI0.XHC_.RHUB, DeviceObj) <- Rename this
|
|
|
|
Scope (_SB.PCI0.XHC_.RHUB) <- Rename this
|
|
```
|
|
|
|
|
|
|
|
Following the example pathing we found, the SSDT should look something like this:
|
|
|
|
**After**:
|
|
|
|
```
|
|
External (_SB.PCI0.XHC1.RHUB, DeviceObj) <- Renamed
|
|
|
|
Scope (_SB.PCI0.XHC1.RHUB) <- Renamed
|
|
```
|
|
|
|
|
|
|
|
## Compiling the SSDT
|
|
|
|
With the SSDT done, you're now [ready to compile the SSDT!](/Manual/compile.md)
|
|
|
|
## Wrapping up
|
|
|
|
Once you're done making your SSDT, either head to the next page to finish the rest of the SSDTs or head here if you're ready to wrap up:
