| 5 | Description: |
| 6 | RPMB frames can be routed to the RPMB device via the |
| 7 | user-space daemon tee-supplicant or the RPMB subsystem |
| 8 | in the kernel. The value "user" means that the driver |
| 9 | will route the RPMB frames via user space. Conversely, |
| 10 | "kernel" means that the frames are routed via the RPMB |
| 11 | subsystem without assistance from tee-supplicant. It |
| 12 | should be assumed that RPMB frames are routed via user |
| 13 | space if the variable is absent. The primary purpose |
| 14 | of this variable is to let systemd know whether |
| 15 | tee-supplicant is needed in the early boot with initramfs. |
