I would like to request a patched DSDT for the ASUS ROG STRIX X670E-I WIFI (ITX version) board. I don't trust my skills in modifying the DSDT myself.  Do I need to provide something? Or maybe a walkthrough so I can try patching it myself.

 

Thanks!

More fundamentally, I wonder why this extra code prevents macOS from booting.

Is macOS unable to read the CPVS region and initialise these G0xx variables? Is it a general issue with macOS? A memory mapping issue? An AMD-specific issue?

Yes macos doesn't read cpvs

Do we know what this field is, and what are the expected values for those G0xx?

 

Not all conditions can be met simultaneously (G000): 

    If (((G002 != 0x03) && (G000 == One)))
    {
        Scope (\_SB.PCI0.GPP7)
        {
            Device (UP00)
            {
 

    If (((G002 != 0x03) && (G000 == 0x02)))
    {
        Scope (\_SB.PCI0.GPP7)
        {
            Device (XH00)

 

so deleting all the conditions create more ACPI objects than would exist if CPVS were properly processed.

 

Possibly more worryingly, there is some debug-like code (calls to M460) and empty stubs 

    If (((G002 != 0x03) && ((G000 == One) && (G002 ==
        0x04)))){}

so there's a risk that the code will further evolve in future BIOS revisions. Maintaing a database of patched DSDTs for successive BIOS versions of boards of interest is going to be cumbersome.

I tested with the new DSDT for the X670E Hero, and it worked with BIOS 1709.

Now I'm testing with the previous BIOS and without DSDT to see if it works too.

I had the misfortune of setting up the setup, updating the BIOS and getting this problem with the 1709. LOL!

Thank you very much for all of your help.

Hi，Could u share EFI with hero 1709?
