Hi,
I'm currently trying to play around with IMA on my raspberry pi3,
however I cannot get it to work since the TPM chip/tpm_tis_spi driver gets initialized way after IMA.
In dmesg this looks like:
dmesg | grep -i tpm
[ 0.726551] ima: No TPM chip found, activating TPM-bypass! (rc=-19)
[ 3.257464] tpm_tis_spi spi0.1: 2.0 TPM (device-id 0x1B, rev-id 16)
[ 3.270398] tpm tpm0: A TPM error (256) occurred continue selftest
[ 3.270418] tpm tpm0: starting up the TPM manually
so 2.5 seconds after ima.
The initcall order should be fine as far as I can see, with ima having a late_initcall.
IMA, tpm_tis_spi and tpm are compiled into the kernel.
