[PATCH 0/12] VTPM mini-os: TPM device drivers for mini-os

Mar 11, 2011, 2:50 PM

Post #1 of 3 (185 views)

This patch adds 3 new drivers to mini-os

tpmfront: Paravirtualized tpm driver that can speak to mini-os tpmback
and linux tpmbk
tpmback: Paravirtualized tpm backend driver that can speak to mini-os
tpmfront and linux tpm_xenu
tpm_tis: Hardware tpm driver. Should work with any TPM device compliant
with the 1.2 spec. Requires io memory passthrough.

I don't have the time to review the driver code in details, but the
overall shape and interaction with the rest of mini-os looks good to me.

This seems like an unrelated change, right?

Yeah that looks like that part should have been included in the blkfront
patch
