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.
