I've been looking into suspend/resume on the Framework Laptop 16, for which I wanted to experiment with overriding the ACPI aml. To that end, I dumped and disassembled the AML with
Which gives me the disassembly. Now, before I change anything, I want to compile that back into machine code again with
Now, this is the first time I attempt anything like this, so I might be doing something stupid. Is it incorrect to expect the output of
acpidump:
sh:
gmc@medeski:~/src/acpi $ sudo acpidump -td > dsdt.asl
gmc@medeski:~/src/acpi $Which gives me the disassembly. Now, before I change anything, I want to compile that back into machine code again with
iasl, but this fails:
sh:
gmc@medeski:~/src/acpi $ iasl -p assembled dsdt.asl

acpidump -d (which uses iasl -d under the hood if I'm not mistaken) to be able to be compiled by iasl again? If so, what would be the correct way to obtain the asl, patch the output and compile it back to machine code?
