The hardcoded tpm_signature is too restrictive to detect many TPMs. For instance, it doesn't accept a QEMU emulated TPM (VID 0x1014 DID 0x0001). Make the TPM detection match that in rombios which accepts a wider range. With this change, the TPM's TCPA ACPI table is generated and the guest OS can automatically load the tpm_tis driver. It also allows seabios to detect and use the TPM. However, seabios skips some TPM initialization when running under Xen, so it will not populate any PCRs unless modified to run the initialization under Xen.

ACPI builder for domain firmware BUILDING ACPI ----------------- Users of ACPI builder are expected to provide an include file that makes available the following: * strncpy * printf * NULL * test_bit * offsetof When compiling build.c, the name of this include file should be given to compiler as -DLIBACPI_STDUTILS=\"<filename>\". See tools/firmware/hvmloader/Makefile for an example. Note on DSDT Table ------------------ DSDT table source code is acpi_dsdt.asl It is already compiled and the output is acpi_dsdt.c Usually, user is not expected to change the acpi_dsdt.asl. In case that the acpi_dsdt.asl need to be updated, please Follow the instruction: # make acpi_dsdt.c Note: DSDT compiler "iasl" is needed. By default, it will be downloaded using wget in Makefile. if it failed, please download manually from http://developer.intel.com/technology/iapc/acpi/downloads.htm. then compile and install iasl
