[solved] ACPI extraction/disassembly issue.

[kevin_1351]

Hello, I'm trying to patch the ACPI of my Xiaomi Notebook Pro. I've already done this process many times before, even with the older Xiaomi Notebook Air without any problems. The issue I have however is that I can't get an error free dissassebly, and I suspect that the issue also lies within the extraction.

The issue:
- I get a bunch of failed lookups in DSDT.dsl
- I get <1, 6126, syntax error, unexpected PARSEOP_NAMESEG, expecting PARSEOP_DEFINITION_BLOCK and premature End-Of-File > when I try to compile

As per [Guide] Patching LAPTOP DSDT/SSDTs, I've done the following:
- installed the latest Clover (rev. 4392)
- pressed F4 while in the Clover menu to extract the ACPI to /EFI/CLOVER/ACPI/origin
- built the latest iasl from GitHub
- created the refs.text
- disassembled with the iasl -da -dl DSDT.aml SSDT*.aml command

A few observations:
- when I use -da I get an error so I guess that the references are already embedded (this being a new laptop and all)
- although I've extracted the ACPI many times with F4, I always end up with SSDT-x10*****.aml
- they aren't duplicates because, as stated in the guide, they must have the same filesizes to be such
- even by removing those X ssdts, the issue persists


Any thoughts? Thanks a lot in advance.

I disassembled your files: iasl -da -dl DSDT.aml SSDT*.aml

The resulting DSDT.dsl has only one error related to BNUM (very common). Easily fixed by removing the extraneous 'External (BNUM, ...' line.

Conclusion: Nothing unusual here.

Doesn't work for me at all, cause there is an entire block of errors before the actual code.

I've used iasl -da -dl DSDT.aml SSDT*.aml now.


I've attached some more files for you. Thanks a lot for your kind help.

Got it working by rebuilding the iasl binary.

I had no such issue with the iasl linked by my guide:

You must have been using the wrong version of iasl.
