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. + +What: /sys/class/tee/tee{,priv}X/revision +Date: Jan 2026 +KernelVersion: 6.19 +Contact: op-tee@lists.trustedfirmware.org +Description: + Read-only revision string reported by the TEE driver.
