tpm: Probe for connected TPM 1.2 or TPM 2 In the TPM passthrough backend driver, modify the probing code so that we can check whether a TPM 1.2 or TPM 2 is being used and adapt the behavior of the TPM TIS accordingly. Move the code that tested for a TPM 1.2 into tpm_utils.c and extend it with test for probing for TPM 2. Have the function return the version of TPM found.

tpm: Added support for TPM emulator This change introduces a new TPM backend driver that can communicate with swtpm(software TPM emulator) using unix domain socket interface. QEMU talks to the TPM emulator using QEMU's socket-based chardev backend device. Swtpm uses two Unix sockets for communications, one for plain TPM commands and responses, and one for out-of-band control messages. QEMU passes the data socket to be used over the control channel. The swtpm and associated tools can be found here: https://github.com/stefanberger/swtpm The swtpm's control channel protocol specification can be found here: https://github.com/stefanberger/swtpm/wiki/Control-Channel-Specification Usage: # setup TPM state directory mkdir /tmp/mytpm chown -R tss:root /tmp/mytpm /usr/bin/swtpm_setup --tpm-state /tmp/mytpm --createek # Ask qemu to use TPM emulator with given tpm state directory qemu-system-x86_64 \ [...] \ -chardev socket,id=chrtpm,path=/tmp/swtpm-sock \ -tpmdev emulator,id=tpm0,chardev=chrtpm \ -device tpm-tis,tpmdev=tpm0 \ [...] Signed-off-by: Amarnath Valluri <amarnath.valluri@intel.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Tested-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> 2017-09-29 13:10:20 +02:00			`common-obj-$(CONFIG_TPM_EMULATOR) += tpm_emulator.o tpm_util.o`
