Witryna9 sie 2024 · For some reason, IMA believes there is no TPM chip, so it activates a bypass. I'm fairly certain that the entry [ 1.244303] has to happen before IMA is loaded so that IMA knows that there is a TPM chip installed. It's worth mentioning that like the IMA support, TPM support is also built in to the kernel and not loaded as a module.
