New versions of iasl have introduced improved C file generation, as
reported in the changelog:
iASL: Enhanced the -tc option (which creates an AML hex file in C,
suitable for import into a firmware project):
1) Create a unique name for the table, to simplify use of multiple
SSDTs.
2) Add a protection #ifdef in the file, similar to a .h header file.
The net effect of that on generated files is:
-unsigned char AmlCode[] =
+#ifndef __SSDT_S4_HEX__
+#define __SSDT_S4_HEX__
+
+unsigned char ssdt_s4_aml_code[] =
The above example is from ssdt_s4.asl.
Fix the build with newer versions of iasl by stripping the '_aml_code'
suffix from the variable name on generated files.

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
