This program is provided to allow examination of ACPI table contents from the UEFI Shell. This can help with investigations, especially at that stage where the tables are not enabling an OS to boot. The program is not exhaustive, and only encapsulates detailed knowledge of a limited number of table types. Default behaviour is to display the content of all tables installed. 'Known' table types will be parsed and displayed with descriptions and field values. Where appropriate a degree of consistency checking is done and errors may be reported in the output. Other table types will be displayed as an array of Hexadecimal bytes. To facilitate debugging, the -s and -d options can be used to generate a binary file image of a table that can be copied elsewhere for investigation using tools such as those provided by acpica.org. This is especially relevant for AML type tables like DSDT and SSDT. The inspiration for this is the existing smbiosview Debug1 Shell command. Many tables are not explicitly handled, in part because no examples are available for our testing. The program is designed to be extended to new tables with minimal effort, and contributions are invited.
