BUG=chrome-os-partner:9707 TEST=manual make make runtests You can also test it by clearing the TPM, then manually looking at the TPM regions. In dev-mode, clear the regions and you'll see something like this: localhost ~ # tpmc read 1007 a 1 0 0 0 0 0 0 0 0 0 localhost ~ # tpmc read 1008 d 1 4c 57 52 47 0 0 0 0 0 0 0 0 localhost ~ # Go back to normal mode and reboot, and you'll see something like this: localhost ~ # tpmc read 1007 a 2 0 1 0 1 0 0 0 0 4f localhost ~ # tpmc read 1008 d 2 4c 57 52 47 1 0 1 0 0 0 0 55 localhost ~ # The important things are that the first number is now 2, instead of 1, and the last number is not zero (it's a checksum, so it'll vary depending on the other numbers, which will themselves vary according to the firmware and kernel versions).
