1*f0c84315SJens WiklanderWhat: /sys/class/tee/tee{,priv}X/rpmb_routing_model 2*f0c84315SJens WiklanderDate: May 2024 3*f0c84315SJens WiklanderKernelVersion: 6.10 4*f0c84315SJens WiklanderContact: op-tee@lists.trustedfirmware.org 5*f0c84315SJens WiklanderDescription: 6*f0c84315SJens Wiklander RPMB frames can be routed to the RPMB device via the 7*f0c84315SJens Wiklander user-space daemon tee-supplicant or the RPMB subsystem 8*f0c84315SJens Wiklander in the kernel. The value "user" means that the driver 9*f0c84315SJens Wiklander will route the RPMB frames via user space. Conversely, 10*f0c84315SJens Wiklander "kernel" means that the frames are routed via the RPMB 11*f0c84315SJens Wiklander subsystem without assistance from tee-supplicant. It 12*f0c84315SJens Wiklander should be assumed that RPMB frames are routed via user 13*f0c84315SJens Wiklander space if the variable is absent. The primary purpose 14*f0c84315SJens Wiklander of this variable is to let systemd know whether 15*f0c84315SJens Wiklander tee-supplicant is needed in the early boot with initramfs. 16
