This feature is enabled by default.
This option allows to turn off the feature.
acpi_no_auto_ssdt [HW,ACPI] Disable automatic loading of SSDT
acpi_no_static_ssdt [HW,ACPI]
Disable installation of static SSDTs at early boot time
By default, SSDTs contained in the RSDT/XSDT will be
installed automatically and they will appear under
/sys/firmware/acpi/tables.
This option turns off this feature.
Note that specifying this option does not affect
dynamic table installation which will install SSDT
tables to /sys/firmware/acpi/tables/dynamic.
acpica_no_return_repair [HW, ACPI]
Disable AML predefined validation mechanism

.TH ACPIDUMP 8
.SH NAME
acpidump \- Dump system's ACPI tables to an ASCII file.
acpidump \- dump a system's ACPI tables to an ASCII file
.SH SYNOPSIS
.ft B
.B acpidump > acpidump.out
.B acpidump
.RI [ options ]
.br
.SH DESCRIPTION
\fBacpidump \fP dumps the systems ACPI tables to an ASCII file
appropriate for attaching to a bug report.
.B acpidump
dumps the systems ACPI tables to an ASCII file appropriate for
attaching to a bug report.
Subsequently, they can be processed by utilities in the ACPICA package.
.SS Options
no options worth worrying about.
.PP
.SH EXAMPLE
.SH OPTIONS
acpidump options are as follow:
.TP
.B Options

.B \-c
Dump customized tables
.TP
.B \-h \-?
This help message
.TP
.B \-o <File>
Redirect output to file
.TP
.B \-r <Address>
Dump tables from specified RSDP
.TP
.B \-s
Print table summaries only
.TP
.B \-v
Display version information

* acpidump - A portable utility for obtaining system ACPI tables and dumping

*
* Obtaining the system ACPI tables is an OS-specific operation.
*
* This utility can be ported to any host operating system by providing a
* module containing system-specific versions of these interfaces:
*
* acpi_os_get_table_by_address
* acpi_os_get_table_by_index
* acpi_os_get_table_by_name
*
* See the ACPICA Reference Guide for the exact definitions of these
* interfaces. Also, see these ACPICA source code modules for example
* implementations:

* source/os_specific/service_layers/oswintbl.c
* source/os_specific/service_layers/oslinuxtbl.c
