Do you have DMAC device under IOReg ?

Hi @CaseySJ

@qthegaijin doesn't have DMAC device on IOREG. Like this device refer to DMAController, Could you verify if you have this one ? And ask for someone have Network issue with AppleVTD enabled, if this device appear ?

I do not have that in my IOReg when the Antelope is connected.


I am going to try to remap the USB ports today when I have time yet again, and see if that gets them to be recognized when DisableIOMapper is turned off. If anyone has any insights to the USB-A ports being disabled that would be much appreciated!

Update:
After trying out different network configurations (swapping ethernet ports, both hotswapping and after reboots), it seems that when the Antelope Control Panel is in remote mode:
- On another Mac machine: it disconnects in 2 minutes or less.
- On iOS: the remote control panel application works 100% of the time.

DMAC device is not dependant on plugged peripherals. This one appear by SSDT-DMAC and look like this, for Z390 Designare :

I have DMAC and like you know I tried. Ethernet and wifi not connected. But with genuine bios. Don't know with your modded bios. About DMAC and other feature here: https://github.com/5T33Z0/OC-Little-Translated

I just followed the isntructions on the OC-Little-Translated for SSDT-DMAC, searched DSDT etc, but when added to my config nothing loads in ioreg still, must need different settings in the SSDT for this mobo possibly?

On Aorus Master, GC-Titan Ridge (Patched NVM33) I do not get DMAC in either scenario:

1. VT-D enabled, Removed dart=0, and unchecked DisableIOMapper-->Result-Fenvi and built-in network do not work, but Apple Thunderbolt to Gigabit Adapter does work.

2. VT-D disabled, dart=0, and checked DisableIOMapper-->Result-Fenvi and built-in network do work, but Apple Thunderbolt to Gigabit Adapter does not work.

On my fully working Z390 Designare with AppleVTD, there is no DMAC device.

@Elias64Fr,

Here's a table of similarities and differences. I'll keep this table updated as more information comes in. Hopefully it may help us identify the culprit.

@StefanAM,

It is not clear to me that SSDT-DMAC is needed because my Z390 Designare with Vt-d enabled has no problems with Ethernet, WiFi, or any other device.

But if someone does have Ethernet and WiFi problems, then I agree they should try SSDT-DMAC.

@NCMacGuy @yosoyoco

Because you're experiencing Ethernet and WiFi problems with Vt-d enabled, please try adding SSDT-DMAC from @StefanAM's post directly above. It must be copied to OC/ACPI folder and a reference must be added to config.plist --> ACPI section.

@Inqnuam @NCMacGuy @yosoyoco,

Please check whether you have a device called DMAC in IORegistryExplorer.
