[Xen-devel] [PATCH] [Linux] [TPM driver] Resume frontend after checkpointing

[Stefan Berger <stefanb@xxxxxxxxxx>]

This patch implements TPM frontend driver resume after checkpointing a
domain.
I also now let the front-end wait for the response from the TPM until
the response is there. A response must come due to the strict request /
response nature of the protocol, but the time until the responses
arrives depends on the type of operation that is executed by the vTPM.
Resending a request is not possible with this type of device.

I tested this patch with the vTPM-relevant tests in the xm-test suite.
