While secure boot permits only properly verified signed kernels to be booted, trusted boot calculates the file hash of the kernel image and stores the measurement prior to boot, that can be subsequently compared against good known values via attestation services.
This patch reads the trusted boot state of a PowerNV system. The state is used to conditionally enable additional measurement rules in the IMA arch-specific policies.
