MacHyperVSupport 0.9.7 PCI Devices Not Working

[PIKACHUIM]

MacHyperVSupport v0.9.7 not working.
Host System: Windows Server 2025
VM System: macOS 14.7.1
I can't see pci devices passthrougth(DDA) from host
However, MacHyperVSupport v0.9.6 works.
Here is my config:
config.zip
By the way, I wonder if MacHyperVSupport can support GPU working with CL/Metal.
And will it work with OCLP?

Thank you!

Please bisect to find the specific commit which introduces the issue.

Sorry for reply late.
I spent some time ruling out the possibility that this issue could be caused by the opencore version or the hardware itself. Therefore, it was still due to the MacHyperVSupport version that caused the inability to use PCI devices. I tested the builds of various versions from 0.9.6 to 0.9.7, and the following are the results:

......(work)
d9dd44d-works. Boot fast and dda pci devices work.
c0344f9-not bootable. It shows disk1,4 error, however I do not have this disk.
a3740c8-not work. Boot very slow and dda pci devices not show in system.
......(not work)

Thank you.

On version-d9dd44d, there are two vgpu show in hackintool instead of one in 0.9.7/0.9.6-release:

The third pci device appears on this build(d9dd44d)
I just want to drive the second pci device GT720 to get metal support.
And I have already apply OCLP's patch but it seems not work.
Can you help me to make it possible? I am very grateful.

What is your passthrough configuration? Just installed Sonoma on a VM but only see the framebuffer and the passed-in GPU, not the basic render driver.

[PIKACHUIM]

I use DDA passthrough configuration, here is a tool: DDATools.zip
It just uses DDA passthrough by official command from Microsoft.
The basic render driver only appears on this build(d9dd44d).

[PIKACHUIM]

DDA passthrough just like this:

Dismount-VMHostAssignableDevice -LocationPath <locationpath> -Force
Add-VMAssignableDevice -VMName $VmName -LocationPath <locationpath>

And I wonder if your GPU passed in will work with Metal/OpenCL or not?

Tested with Big Sur 11.7.10 and a Quadro K600 that DDA does function, although there are some oddities with backtraces being generated when the cursor moves. The Hyper-V synthetic framebuffer must be disabled with -hvgfxboff boot argument.

Thus far the only GPUs I've been able to get working are Kepler cards on the respective supported versions of macOS. AMD cards do not appear to work at this time. Anything above Monterey for NVIDIA cards would be out of scope of this bugtracker as that would require OCLP.

I have a GT720 and I have installed macOS 11.7.10 but it does not work.
I boot with -hvgfxboff argument, and the use MacHyperVSupport v0.9.6.
(I can NOT use MacHyperVSupport v0.9.6 because it does not work at all)
If without -hvgfxboff, I can see the GT720 shows in the pci devices list:

If I boot with -hvgfxboff, I can NOT see login screen in Hyper-V and vnc can NOT connect.
Here is system report and screenshot from Hackintool:

[PIKACHUIM]

Only once I boot with -hvgfxboff, I can see the system report and pci devices list only have my GT720.
There is no Hyper-V vGPU. But it still not work, metal shows not support. (I forgot to take a screen shot)
