If I apply the device-passthrough patch to KVM, QEMU, OVMF, can I passthrough nvidia's A100 series GPUs in the booted TDX CVM?

If I apply the device-passthrough patch to KVM, QEMU, OVMF,
Can I passthrough nvidia's A100 series GPUs in the booted TDX CVM?
Or can I only passthrough nvidia's H series GPUs?

It is not specific to H series, we have tested passthrough A10 before, VFIO should be generic. But to make your GPU work, some adjustment might be needed as A10 does not have CC mode.

What specific adjustments need to be made?

It is out of the scope here. You need to make sure the card driver supports this. Otherwise, you need to change the driver behavior to make it work with such flow.
