device paths

[ezsolt]

Can somebody please explain how the different paths work in SSDT?

this is not working, I can not rename PEGP to GFX1

    Scope (\)
    {
        Scope (\_SB)
        {
            Scope (PCI0)
            {
                Scope (PEG0)
                {
                    Device (GFX1)
                    {
                           Name (_ADR, Zero) 
                           ...
                           Methods, etc.
                    // and finally removing PEGP
                    Scope (PEGP)
                    {
                        Name (_STA, Zero)                   // Removing factory EC0 device
                    }
...

this is working, I can rename PEGP to GFX1

DefinitionBlock ("", "SSDT", 1, "APPLE", "GFX1", 0x00001000)
{
    Device (\_SB.PCI0.PEG0.GFX1)
    {
        ...
    }

    Name (\_SB_.PCI0.PEG0.PEGP._STA, Zero)
}

In your first example you may need to use 'external'

External (\_SB.PCI0.PEG0, DeviceObj)

Scope (\_SB.PCI0.PEG0) {
Device (PEGP) {
...
}
Device (GFX0) {
...
}
}

Yes i have all the external stuff there, the ssdt itself is correct, i can compile it. That is not the problem

Note enough information provided above... (your indenting may be misleading, or may point out your mistake...)??

 

[ezsolt]

sorry for not providing enough infos.

Here I have the two SSDT-s, I have.
The SSDT-GPU.dsl is working fine, the SSDT.dsl is not, and I can not see why.

Impossible to know without native ACPI files, EFI/Clover, and ioreg.
For example, there may be an existing _INI at _SB._INI. And you're trying to declare a new one... it would cause the system to ignore the rest of your file...

thanks

Your Clover bootlog (extracted from ioreg) shows SSDT.aml does not exist in ACPI/patched.

2:080  0:000  === [ ACPIPatchedAML ] ====================================
2:080  0:000  Unsorted
2:080  0:000  Inserting ssdt-cpu.aml from EFI\CLOVER\ACPI\patched ... Success

You can't expect an SSDT to have any effect when it is not loading/not present in ACPI/patched.

Aargh, I guess this is a clover issue.
Now my ssdt is loading, but when using SortedOrder in SSDT.aml doesn't load.

Your Clover bootlog shows that SortedOrder does not include SSDT.aml...

8:084  0:000  === [ ACPIPatchedAML ] ====================================
8:084  0:000  Sorted
8:084  0:000  Inserting table[0]:SSDT-USB.aml from EFI\CLOVER\ACPI\patched ... Success
8:087  0:003  Inserting table[1]:SSDT-GPU.aml from EFI\CLOVER\ACPI\patched ... Success
8:090  0:002  Inserting table[2]:SSDT-HDEF.aml from EFI\CLOVER\ACPI\patched ... Success
8:092  0:002  Inserting table[3]:SSDT-CPU.aml from EFI\CLOVER\ACPI\patched ... Success

You should not expect files that are not in SortedOrder to load.
