From 55a82ab3181be039c6440d3f2f69260ad6fe2988 Mon Sep 17 00:00:00 2001 From: Kylene Jo Hall Date: Sun, 8 Jan 2006 01:03:15 -0800 Subject: [PATCH] tpm: add bios measurement log According to the TCG specifications measurements or hashes of the BIOS code and data are extended into TPM PCRS and a log is kept in an ACPI table of these extensions for later validation if desired. This patch exports the values in the ACPI table through a security-fs seq_file.
