What information is present in the ACPI tables?

Question

What do ACPI tables contain?

I tried googling it, and it did not help.

Answer 1

On a rather abstract level the ACPI tables contain (from Advanced Configuration and Power Interface):

... description of system hardware in a platform-independent manner, and are presented as either fixed formatted data structures or in ACPI Machine Language (AML). The main AML table is the DSDT (differentiated system description table).

The Root System Description Pointer is located in a platform-dependent manner, and describes the rest of the tables.
