[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

[Elias64Fr]

Yes, baby steps...

But step too,
Now we have to find the firmware of an iMac with embedded TitanRidge like iMac19,1 to make diff like osy86 Method !

Very nice !

You can inject ThunderboltDROM property:
71000000 000000ED 00E04034 98016900 ED0008C0 01010881 80028000 00000882 90018000 00000883 80048001 00000884 90038001 00000585 50000005 86500000 02C70B88 20010064 00000000 00038980 058A5040 00058B50 40000B01 47494741 42595445 0011025A 33393020 44455349 474E4152 4500

It seem that port 7 is used for IOThunderboltSwitchType3 !

UPDATE:

Analyzed for long time !

I haven’t examined the ROM file any further yet (out of the house now), so some questions:

• Are these bytes extracted from the ROM file?
• Should Thunderbolt DROM be injected via Clover/SSDT or patched into the Winbond chip directly?
• When you say that Port 7 is used for IOThunderboltSwitchType3, does that mean we can modify SSDT-TbtOnPch or ...? Just trying to understand the practical implications of this!

Update:
My mistake: You are simply explaining the various components of TB DROM. Decoding each byte of DROM. Very nice! I’ll inject this via Clover or SSDT this evening.

@CaseySJ,

• Yes I just have extracted them from your file !
• Sure ! I have done it but I noted that is not required for Full Thunderbolt Tree, I hadn't any properties on my first post as viewing on IOReg screenshot https://www.tonymacx86.com/threads/...olt-3-i7-9700k-amd-rx-580.267551/post-2053308
• No, TBSwitch populating is done by driver after correct configuration .. maybe by CRMW written data but that's unverified and pure speculation ! Current data (Mine and Designare testing files) have been extracted from iMac SSDT-TbtOnPch and I don't know what it mean. More search on Github opensource code for Thunderbolt feature is required.

@Elias64Fr

Previously I gave you a modified DSDT for Designare Z390 instead of the original DSDT. In case it makes any difference, attached are all of the original unmodified ACPI tables (from firmware version F8).

 

[S1lla]

Wouldn't it make more sense to look at the SSDT from the new Macpro7.1? @Elias64Fr

Thanks ! I had ever extracted them from Z390 Designare BIOS firmware from available on Gigabyte website

Apple has both TbtOnPch and TbtOnPci depending on the Mac model. We're specifically looking for TbtOnPch, so if either iMac19,1 or MacPro7,1 has this then we can examine and borrow from it. However, all of these SSDTs are also contained in the Apple firmware.bin files.

Hi @S1lla,

Unfortunately, It (CRMW written data) seem to be same as iMac19,1 .. Titan ridge too !

Attached MacPro7,1 SSDT TBT:

 

[S1lla]

Where did you get this data from if it is not a secret?

Somewhere on web .. during search ! I have save it immediately after but I agree that isn't sure source
