This patch enables TPM2 passthrough to post-launched VM with eventlog support. User starts by providing command line "--acpidev_pt <TPM2_HID>", of which the <TPM2_HID> will be searched from /proc/iomem for TPM2 buffer start address and size. Furthermore, If TPM2 eventlog is supported, TPM2 eventlog information will be retrieved from sysfs TPM2 table and passed-through as well. v4 -> v5: move tpm2 related logic from acpi.c to tpm.c multiple API rename Tracked-On: #6686 Signed-off-by: Yifan Liu <yifan1.liu@intel.com> Acked-by: Wang, Yu1 <yu1.wang@intel.com>
