You’re misunderstanding the intention of this patch. It has nothing to do with GPU passthrough. The only thing it changes is how bhyve reports the number of vcpus to the guest. If you like to test the patch, rebuild OVMF with this patch, start a VM and check if the guest detects the correct number of cpus. Best regards Corvin Beckhoff Automation GmbH & Co.
