From 30fc8d138e9123f374a3c3867e7c7c5cd4004941 Mon Sep 17 00:00:00 2001 From: Jarkko Sakkinen Date: Fri, 12 Dec 2014 11:46:39 -0800 Subject: tpm: TPM 2.0 CRB Interface tpm_crb is a driver for TPM 2.0 Command Response Buffer (CRB) Interface as defined in PC Client Platform TPM Profile (PTP) Specification. Only polling and single locality is supported as these are the limitations of the available hardware, Platform Trust Techonlogy (PTT) in Haswell CPUs. The driver always applies CRB with ACPI start because PTT reports using only ACPI start as start method but as a result of my testing it requires also CRB start.
