The components of bsssd

Bsssd consists of OpenBSD and FreeBSD device drivers for the supported Trusted Platform Modules (TPM), see Hardware.

In addition, bsssd provides OpenBSD and FreeBSD ports (port) of necessary linux userland components.

Kernel components

Device Driver

The device drivers access the TPM via a device node /dev/tpm. See Architecture of the TCG Software Stack.
