1 What: /sys/firmware/secvar
4 Description: This directory is created if the POWER firmware supports OS
5 secureboot, thereby secure variables. It exposes interface
6 for reading/writing the secure variables
8 What: /sys/firmware/secvar/vars
11 Description: This directory lists all the secure variables that are supported
12 by the firmware.
14 What: /sys/firmware/secvar/format
17 Description: A string indicating which backend is in use by the firmware.
21 On powernv/OPAL, this value is provided by the OPAL firmware
22 and is expected to be "ibm,edk2-compat-v1".
26 has the form "ibm,plpks-sb-v<version>", or
27 "ibm,plpks-sb-unknown" if there is no SB_VERSION variable.
29 What: /sys/firmware/secvar/vars/<variable name>
32 Description: Each secure variable is represented as a directory named as
