The following series of patches implements a multi-instance vTPM driver that can dynamically create TPM 'server' and client device pairs.
Using an ioctl on the provided /dev/vtpmx, a client-side vTPM device and a server side file descriptor is created. The file descriptor must be passed to a TPM emulator. The device driver will initialize the emulated TPM using TPM 1.2 or TPM 2 startup commands and it will read the command durations from the device in case of a TPM 1.2. The choice of emulated TPM device (1.2 or 2) must be provided with a flag in the ioctl.
