I am enabling IMA on a ZynqMP based platform using an SPI based TPM from Infineon. The SPI TPM driver is built-in but since the IMA is initalized from a late_initcall, IMA never finds the TPM. Is there a recomended way to work around this issue? fio@uz3cg-dwg:~$ dmesg | grep tpm [ 3.381181] tpm_tis_spi spi1.1: 2.0 TPM (device-id 0x1B, rev-id 22) [ 3.423608] tpm tpm0: A TPM error (256) occurred attempting the self test [ 3.430406] tpm tpm0: starting up the TPM manually fio@uz3cg-dwg:~$ dmesg | grep ima [ 3.525741] ima: No TPM chip found, activating TPM-bypass! [ 3.531233] ima: Allocated hash algorithm: sha1 TIA jorge
