To send commands to the TPM device, bhyve can use the host TPM driver by reading and writing from /dev/tpmX. Using this approach, only the host TPM driver has to detect and interact with the physical TPM interface. This simplifies bhyve's code much. As the host TPM driver has to interact with the TPM regardless of bhyve making use of it or not, makes it a good approach.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
