Subject: [Qemu-devel] [PATCH 0/2] TPM NVRAM persistent storage
Date: Tue,  4 Jun 2013 14:18:39 -0400	[thread overview]
Message-ID: <1370369921-14925-1-git-send-email-coreyb@linux.vnet.ibm.com> (raw)

This patch series provides persistent storage support that a TPM
can use to store NVRAM data.  It uses QEMU's block driver to store
data on a drive image.  The libtpms TPM 1.2 backend will be the
initial user of this functionality to store data that must persist
through a reboot or migration.  A sample command line may look like
this:

qemu-system-x86_64 ...
-drive file=/path/to/nvram.qcow2,id=drive-nvram0-0-0
-tpmdev libtpms,id=tpm-tpm0
-device tpm-tis,tpmdev=tpm-tpm0,id=tpm0,drive=drive-nvram0-0-0

Thanks,
Corey
