MP 7,1 OpenCore on Mac Pro 7,1

Posting this here just for my own benefit:

Getting a hang near the end of the boot process with the current AML file I have made (attached).

Originally thought this was related to the apfs_keybag error, but noticed it on normal boot too so unlikely related.

You put it as an AML not DSL right?

 

[trus0und]

Yes, this is the current file I have in there (attached). Also, tried the device properties way, but seems abit odd. I think the device path is right, but still doesnt get disabled.

 

[trus0und]

I can confirm device properties are injecting mind you, as I just tried flipping my PCIE Drive for Windows to built-in and that worked just fine!

 

[trus0und]

Finally have had another chance to jump into this, but am still having a few issues understanding why this isnt disabling. This is what I can see in Hackintool:

I believe the PciRoot is correct, and gfxutil does show the same thing. This is what I have added to the DeviceProperties in OpenCore:

This does not work, and after the reboot I can still see the additional GPU in the System Info. Also this is how it displays in the PCI Devices:

If anyone can point me in the right direction here I would be very grateful!

When you add properties you have to also delete them if they already exist.

 

[trus0und]

@startergo Thank you, I have attempted adding the properties like this but have found very little on whether I am doing the delete part correctly as I am finding very little in the way of info on that.

This is where I am at, but it just seems to be injecting nothing at all. I wonder if the PciRoot is incorrect?

Thank you again for all your help!

Made some great progress tonight! With the help of MaLd0n, we have lift off! Was even able to customise the DSDT Patch a little:

Sleep/Wake is working again. My drives show as internal. I have OpenCore on the internal EFI and OpenCapony is setup so I have a boot picker! Success!!!

What changed?

 

[trus0und]

He made a DSDT patch for me which disables the GPU only on Darwin. I can share it if you want to see how it was done. I am not really sure how he did it because he added a DGPU section and then inside that he added some injects that look alot like the SSDT injects.

Thanks. Any changes in the config file?

 

[trus0und]

There were a couple of changes. I have to load the custom DSDT, and also we enabled RebaseRegions, though I am not entirely sure if thats necessary.

I may see if I can figure out whether this can be injected with a less all around patch of the DSDT, but ultimately if it works it works so that would be for my own learning if anything!

Ive attached the config for your info

@startergo My apologies, been a busy couple of days! I did use that guide, and from the Windows side it appears my path is _SB_.PC03.BR3A. So in saying that, I modified the SSDT to this which I believe is correct:

}

I will double check it though as I suppose it is probably wrong

According to the modified DSDT, which works this SSDT should do the same without adding DSDT:

Perhaps that would work in conjunction with the RebaseRegions option 🧐

Before when I tried this, I got a hang somewhere along the line during boot. I'll give it another go at some stage!

 

[startergo]

This is what works for me:

NVIDIA is disabled in Big Sur and in Windows both work:

Spoiler: IOREG

 

[trus0und]

I see, and the AAPL, ndrv-dev setting disables the loading of the driver? Seems the driver that loads for me without the DSDT is IONDRVSupport I believe and that is what isn't loading with the DSDT patch.

Yes here is more of the Apple NVIDIA code:

Unfortunately sleep does not work.

I finally got my SSDT to disable NVIDIA card. Since my setup is not ordinary and I have an expansion board connected to the second slot a new device/s had to be created in the SSDT, because the ACPI path is missing. This is the original ioregistry hook:
Windows ACPI path:

ACPI(_SB_)#ACPI(PCI0)#ACPI(IOU1)#PCI(0000)#PCI(0400)#PCI(0000)

Apple IORegistry path:

IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/IOU1@7/IOPP/PXS2@0/IOPP/pci-bridge@4/IOPP/GFX1@0

And this is the modified one:

IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/IOU1@7/IOPP/PXS2@0/IOPP/PBR4@4/IOPP/GFX1@0

As you can see in the place of the original pci-bridge, a new device PBR4 was created:

I have a Mac Pro 7,1 running Big Sur and I want to try using OpenCore/Innie to show the external drives as internal and then see if I can install macOS to 2 NVMe blades in RAID 0. Even if I can't do that, it would be nice to have my NVMe drives show as internal.

Does someone have this configurtion handy? I'm not running an Nvidia card... just stock RX580 MPX.

Sorry for the delay in reply, I have taken some time away for my health. You can basically use the config provided config in this post: https://forums.macrumors.com/threads/opencore-on-the-mac-pro.2207814/ as its practically as clean as you can go for the config which is what you'd want for a legit Mac. From there, you can use Hackintool to find your PCIe Device Path for your NVMe blades, and then inside of OpenCore's config you will need to set the builtin setting to 1.

@startergo Sorry to tag you directly. I am having a hell of a time getting Windows to show up in the OC boot picker here. Do you know if a normal bootcamped Windows install should show up? If not, do you know if there is a special way I have to do this on a real Mac? I tried the steps in the OpenCore on the Mac Pro main thread, but to no avail unfortunately. Thanks in advance for any help you can provide!

 

[startergo]

Sure you have to chain load opencore from refindplus. From the refindplus you can load non UEFI Windows. The easiest way is to use @Dayo MybootMGR.

I see, and if I just want to use OpenCore on its own it just has to be a UEFI install of Windows, is that right?
