| What: /sys/class/tee/tee{,priv}X/rpmb_routing_model |
| Date: May 2024 |
| KernelVersion: 6.10 |

| 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. |
