Subject: [PATCH] libacpi: fixes for iasl >= 20180427
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
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.
