Passthrough adapter to ESXi VM not working

[sjkjs]

I'm running ESXi 8.0.1 on an HP DL380p Gen8 and want to pass through the Coral devices to a VM.

If I SSH into the ESXi server and run lspci, it shows:

0000:0c:00.0 Non-VGA unclassified device: Global Unichip Corp. Coral Edge TPU 0000:0d:00.0 Non-VGA unclassified device: Global Unichip Corp. Coral Edge TPU

Under ESXi PCI devices I see that passthrough is not supported:

Through vCenter it says "This device cannot be made available for VMs to use" when selecting it.

If I click toggle passthrough, it displays an error saying "This device cannot be made available for VMs to use"

Has anyone gotten this to work before?

same problem, any new?

Passthrough requires VM-d/iommu support and VM-d/iommu enabled in BIOS. Is it something what was already tried?

Yes, VT-d was enabled and other devices are successfully being used in passthrough mode.

I've since given up and sold the Coral so I can't test any further.
