hw/arm: introduce xenpvh machine Add a new machine xenpvh which creates a IOREQ server to register/connect with Xen Hypervisor. Optional: When CONFIG_TPM is enabled, it also creates a tpm-tis-device, adds a TPM emulator and connects to swtpm running on host machine via chardev socket and support TPM functionalities for a guest domain. Extra command line for aarch64 xenpvh QEMU to connect to swtpm: -chardev socket,id=chrtpm,path=/tmp/myvtpm2/swtpm-sock \ -tpmdev emulator,id=tpm0,chardev=chrtpm \ -machine tpm-base-addr=0x0c000000 \ swtpm implements a TPM software emulator(TPM 1.2 & TPM 2) built on libtpms and provides access to TPM functionality over socket, chardev and CUSE interface. Github repo: https://github.com/stefanberger/swtpm Example for starting swtpm on host machine: mkdir /tmp/vtpm2 swtpm socket --tpmstate dir=/tmp/vtpm2 \ --ctrl type=unixio,path=/tmp/vtpm2/swtpm-sock & Signed-off-by: Vikram Garhwal <vikram.garhwal@amd.com> Signed-off-by: Stefano Stabellini <stefano.stabellini@amd.com> Reviewed-by: Stefano Stabellini <sstabellini@kernel.org> 2023-06-15 02:03:37 +02:00			`#ifndef HW_XEN_ARCH_ARM_HVM_H`
