".SH DESCRIPTION\r\n"
|
|
" \r\n"
|
|
" This program is provided to allow examination of ACPI table values from the\r\n"
|
|
" UEFI Shell. This can help with investigations, especially at that stage\r\n"
|
|
" where the tables are not enabling an OS to boot.\r\n"
|
|
" The program is not exhaustive, and only encapsulates detailed knowledge of a\r\n"
|
|
" limited number of table types.\r\n"
|
|
" \r\n"
|
|
" Default behaviour is to display the content of all tables installed.\r\n"
|
|
" 'Known' table types (listed in NOTES below) will be parsed and displayed\r\n"
|
|
" with descriptions and field values. Where appropriate a degree of\r\n"
|
|
" consistency checking is done and errors may be reported in the output.\r\n"
|
|
" Other table types will be displayed as an array of Hexadecimal bytes.\r\n"
|
|
" \r\n"
|
|
" To facilitate debugging, the -s and -d options can be used to generate a\r\n"
|
|
" binary file image of a table that can be copied elsewhere for investigation\r\n"
|
|
" using tools such as those provided by acpica.org. This is especially\r\n"
|
|
" relevant for AML type tables like DSDT and SSDT.\r\n"
|
|
" \r\n"
|
|
"NOTES:\r\n"
|
|
" 1. The AcpiTable parameter can match any installed table type.\r\n"
|
|
" Tables without specific handling will be displayed as a raw hex dump (or\r\n"
|
|
" dumped to a file if -d is used).\r\n"
|
|
" 2. -s option supports to display the specified AcpiTable type that is present\r\n"
|
|
" in the system. For normal type AcpiTable, it would display the data of the\r\n"
|
|
" AcpiTable and AcpiTable header. The following type may contain header type\r\n"
|
|
" other than AcpiTable header. The actual header can refer to the ACPI spec\r\n"
|
|
" 6.3\r\n"
|
|
" Extra A. Particular types:\r\n"
|
|
" APIC - Multiple APIC Description Table (MADT)\r\n"
|
|
" BGRT - Boot Graphics Resource Table\r\n"
|

".SH STANDARDS\r\n"
|
|
" \r\n"
|
|
" Table details correspond to those in 'Advanced Configuration and Power\r\n"

|
" Interface Specification' Version 6.3 [January 2019]\r\n"
|
|
" (https://uefi.org/specifications)\r\n"
|
|
" \r\n"
|
|
" NOTE: The nature of the ACPI standard means that almost all tables in 6.3\r\n"
|
|
" will be 'backwards compatible' with prior version of the specification\r\n"
|
|
" in terms of structure, so formatted output should be correct. The main\r\n"

|
" exception will be that previously 'reserved' fields will be reported\r\n"
