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