+Directory Structure
+===================
+tools/vtpm/tpm_emulator-0.2b.tar.gz -> TPM Emulator downloaded at build
time that will
+ be patched and used for our vtpms
+tools/vtpm/vtpm.patch -> patch applied to tpm_emulator to
make vtpm
+tools/vtpm/vtpm/ -> (created on build) tpm_emulator
moved to ring 3,
+ listens on a pair of fifos for TPM
commands,
+ persistent state is sent via named
fifo to vtpm
+ manager, which encrypts it and
protects it.
+tools/vtpm/tpm_emulator.patch -> To allow for debugging and testing
on non-TPM
+ platforms, this patches the emulator
to allow
+ it to be inserted into the dom0
kernel
+tools/vtpm/tpm_emulator-0.2 -> (created on build) directory
containing patched emulator
+
+Compile Flags
+===================
+VTPM_MULTI_VM -> Defined (not finished): VTPMs run in their own
VMs
+ Not Defined (default): VTPMs are processes
+
+Requirements
+============
+- xen-unstable
+- IBM frontend/backend vtpm driver patch
+- vtpm_managerd
+
+vtpmd Flow (for vtpm_manager. vtpmd never run by default)
+============================
+- Launch the VTPM manager (vtpm_managerd) which which begins listening to the
BE with one thread
+ and listens to a named fifo that is shared by the vtpms to commuincate with
the manager.
+- VTPM Manager listens to TPM BE.
+- When xend launches a tpm frontend equipped VM it contacts the manager over
the vtpm backend.
+- When the manager receives the open message from the BE, it launches a vtpm
+- Xend allows the VM to continue booting.
+- When a TPM request is issued to the front end, the front end transmits the
TPM request to the backend.
+- The manager receives the TPM requests and uses a named fifo to forward the
request to the vtpm.
+- The fifo listener begins listening for the reply from vtpm for the request.
+- Vtpm processes request and replies to manager over shared named fifo.
+- If needed, the vtpm may send a request to the vtpm_manager at any time to
save it's secrets to disk.
+- Manager receives response from vtpm and passes it back to backend for
forwarding to guest.
