[Xen-devel] How to get the instance number from TPM Command in VTPM

[XingBin <xbhust@xxxxxxxxx>]

Hi all,
    How the virtual TPM dispatch TPM commands ?
I know that If multiple virtual machines send TPM commands to the virtual TPM,
it can be determined from the instance number of a TPM command from
which VM the command originated.
My question is how the instance number of a TPM command can be prepended? thanks
