Firmware Test Suite - acpidump utility
This utility loads the ACPI tables and will annotate the tables where possible. This is useful way of inspecting the configuration settings in each table. Tables that are not described in the ACPI specification are dumped out in a hex dump format.
The annotation format is as follows:
TTTT @ xxxxxxxx (ddd bytes) --------------------------- [0xaaa bbbb nn] Text name of field: contents where: TTTT is the name of a table, xxxxxxxx is the address of the table in memory, aaa is the offset of the field in the table (in hex), bbbb is the offset of the field in the table (in decimal), nn is the size of the field in bytes (in decimal)
Note that some fields are bitfields, so these are dumped out as the integer value followed by an annotated dump of the individual bit field values.
for example:
Dump ACPI tables.

[0x0b4 0180 8] Entry 18 UEFI: 0x00000000dafd9000The default mode of this utility is to try and use the host machine's ACPI tables which requires root permissions to be able to load this data from firmware. However, one can load in ACPI tables from other machines using the --dumpfile option. The ACPI tables can be loaded in from the output from acpidump or from using "sudo fwts --dump".
Examples:
sudo fwts acpidump -
..runs the acpidump on your machine and dumps the output to stdout.
fwts acpidump --dumpfile=apcidump.dat -
..runs the tool using ACPI tables in the dump file acpidump.dat as the input and dumps the test results to stdout.
sudo acpidump > acpidump.dat fwts acpidump --dumpfile=acpidump.dat
..dumps the tables using acpidump and loads them in and runs the tool with results appended to results.log
sudo fwts --dump fwts acpidump --dumpfile=acpidump.log -
..dumps the tables using fwts and loads them in and runs the tool with results going to stdout.
