On systems without a TPM, IMA goes into a "by-pass" mode, which stores the measurements without extending the TPM PCR. On Power, there isn't a HW TPM, but on Power running PowerVM there is a virtual TPM(vTPM). On Power running PowerKVM there isn't support for vTPM, yet. The Kconfig needs to differentiate between the two. > Signed-off-by: Michael Ellerman <m...@ellerman.id.au> [CC'ing: Vicky(Lo, Hon Ching), Ashley Lai, George Wilson] Sorry, I'm still waiting to hear back from the developers/testers.
