I've been using Stefan's script to automate table dumping:


Then I compile the SSDT table with iasl -tc to make a c source file.
You can take the contents of the array and insert it into
tools/acpiexec/aeexec.c in the place of the Ssdt1Code[] data.  Then
when you load your DSDT it can refer to the data in the SSDT.

The other way to do it is to disassemble the SSDT and DSDT and combine
them into one file.  I like putting the SSDT into the executable
