Errors when trying to dissasemble my DSDT.aml file

[flexmcmurphy]

Hello,

 

I am following this section of the Opencore guide https://dortania.github.io/Getting-Started-With-ACPI/Laptops/trackpad-methods/manual.html#finding-the-acpi-path and trying to dissasemble my DSDT.aml file to make my own SSDT-GPI0.dsl

 

I got the DSDT.aml file using the SSDTTime python script.

 

When I use the command

# iasl DSDT.aml

 

I get the error:

iASL Warning: There were 6 external control methods found during disassembly, but only 0 were resolved (6 unresolved). Additional ACPI tables may be required to properly disassemble the code.

 

When I use the command:

# iasl -e SSDT*.aml -d DSDT.aml

 

I get the error:

ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog (20190509/psobject-264)

 

Each time when I open the produced DSDT.dsl file I cannot search and find the string: Device (GPI0).

 

Any idea what I am doing wrong?

 

Cheers!

There are duplicated symbols in the DSDT/SSDT* set.

Try loading SSDT files individually with '-e' until you find the right one, or a suitable combination of SSDT files.

You might find it easier to use maciASL (check for latest version) and pull in any desired patches specific to your hardware.

DSDT extraction from linux:
cd ~/Desktop
sudo cat /sys/firmware/acpi/tables/DSDT > DSDT.aml
