H A D | sockets.h | 4549a8b7 Wed Feb 27 11:47:53 CST 2013 Stefan Berger <stefanb@linux.vnet.ibm.com> Add a TPM Passthrough backend driver implementation This patch is based of off version 9 of Stefan Berger's patch series "QEMU Trusted Platform Module (TPM) integration" and adds a new backend driver for it. This patch adds a passthrough backend driver for passing commands sent to the emulated TPM device directly to a TPM device opened on the host machine. Thus it is possible to use a hardware TPM device in a system running on QEMU, providing the ability to access a TPM in a special state (e.g. after a Trusted Boot). This functionality is being used in the acTvSM Trusted Virtualization Platform which is available on [1]. Usage example: qemu-system-x86_64 -tpmdev passthrough,id=tpm0,path=/dev/tpm0 \ -device tpm-tis,tpmdev=tpm0 \ -cdrom test.iso -boot d Some notes about the host TPM: The TPM needs to be enabled and activated. If that's not the case one has to go through the BIOS/UEFI and enable and activate that TPM for TPM commands to work as expected. It may be necessary to boot the kernel using tpm_tis.force=1 in the boot command line or 'modprobe tpm_tis force=1' in case of using it as a module.
