Overview of ACPI

Dump DSDT/SSDT

There are many ways to dump ACPI tables. The most easy way is to select and read out tables file from /sys/firmware/acpi/tables 

user@here:~$ tree /sys/firmware/acpi/tables/

|-- ATKG
|-- BOOT
|-- DBGP
|-- DSDT
|-- ECDT

|-- SSDT
`-- dynamic
    |-- SSDT2
    |-- SSDT3
    |-- SSDT4
    `-- SSDT5

You can copy files out with root privilege and use iasl to decompile it 

user@here:~$ sudo cp /sys/firmware/acpi/tables/DSDT ~/DSDT.bin
