Thunderbolt 3 Modified Firmware Custom SSDT Discussion

[CaseySJ]

I just adapted my TB SSDT to Bus 2. Didn't help. Will check the BIOS to see if there's something I missed.

Was this on the Z390 Designare?

No. Z170x. Good reminder not to take predictable behavior for granted. The Z170x boots again after lots of resets etc. BIOS settings that worked before suddenly didn't, etc.

 

[zipb]

Oh, and I have 3 TB ports now. Amazing.

 

[zipb]

Let's see if it shuts down properly. That was a problem too.

You have to use the SSDT I posted earlier. If you change Bus ID in HackinDROM website, you'll get 3 ports. It's a bug. Nevertheless, testing this card on Z170x is an invalid experiment.

@Inqnuam,

When we change Bus ID on hackinDROM website, it makes this error:

See those red zeros? They should be equal to Bus ID, which in this example is 2. Checksum has to be recalculated.

very weird behaviour!
If you change TB Bus Id multiple times you'll see different results each time.
However 1, 5, 6, 7, 8 and 9 are always correct.
Will check this asap

@CaseySJ
I dont remembre well
are every "0x08" hex + 2 and + 4 the marker for the tb bus id ?

Please look in this example we have only 2 of them
is this correct ?

EDIT:
I think I have fixed it
Please let me know if it is correct

If a controller has only one Thunderbolt port, then we'll see 0x08, 0x81 ... and 0x08, 0x82.
If a controller has two Thunderbolt ports, then we'll see 0x08, 0x81, ..., 0x08, 0x82, ..., 0x08, 0x83, ..., and 0x08, 0x84

EDIT:
I think I have fixed it
Please let me know if it is correct

Let me check...

Update: Yes it works correctly now for both 1-port and 2-port Thunderbolt controllers!
