Re: iasl and SSDT disassembling limitations

[Lin Ming <ming.m.lin@intel.com>]

We have added a "-e" option to iasl that include tables for external
symbol resolution. See
http://git.acpica.org/repos/?p=acpica.git;a=commitdiff;h=2f705a1b06109e12bd2659d0e12215710a5622b7


Example: To disassemble an SSDT with external symbols defined in DSDT:

iasl -e dsdt.aml -d ssdt.aml

Without this information, it does not know how many expressions to parse after the control method invocation in order to create the arguments. The information is simply not available. So it tries to guess.
