Is there any pre-compiled DSDT for MacMini 2018 i7, 32Gb available?

Hello there, after struggling a couple of weeks making the DSDT working, finally it does, in my Sony Vaio vpcyb35al, I want to contribute with my compressed zip file. Now I'm still facing the error 43 and the hotswapping (struggling with the bios whitelist which I want to remove) and still no output by the external but it seems like it's working properly and it has its own resources

Oh, well... When ‘asl /u dsdt.dat’ I get:  asl_ERR: UnAsmOpcode: invalid opcode class 0 and dsdt.asl is created with 0 Kb.

Any ideas?

Also -  dsdt.dat seems to be only 28Kb

Trying from W10 20H2 on Mac Mini 2018 here.

 Could something like simply renaming the .dat file work as mentioned in this link? -  https://dortania.github.io/Getting-Started-With-ACPI/Manual/dump.html#from-windows

 

...Or .asl is not necessary for Intel method at all...?

Update: I was able to create and edit modified file, but cannot compile it back with iasl to .aml Process ends with one error (I do not see anything specific on that line), and no .aml file created.

I actually decompiled DSDT, edited and compiled .aml on macOS. There were no errors.

Successfully loaded it to registry from W10 afterwards. However, it did not sort out my ‘Code 12’ issue.

I noticed that even prior to the modification the Device Manager showed an entry with Large Memory’. No idea as there were no modifications done.

After applying an edited .aml - a second entry appeared as it shoud be.

Can anyone comment on the (2 entries)? 

Did I had to edit the one which was already there, maybe within the DSDT?

@susurs, 2017 and newer Macs have Large Memory allocation in Boot Camp. This is through the Mac firmware. If you encounter error 12 with one of the Macs, DSDT override doesn't help unfortunately.

@itsage, ok, good to know, thank you!

In any case - it was a good ‘scientific’ experience as I was able to successfully complete the process (even if it does not give results).
