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. |
