91 * Enable "slack mode" of the AML interpreter? Default is FALSE, and the
92 * interpreter strictly follows the ACPI specification. Setting to TRUE
93 * allows the interpreter to ignore certain errors and/or bad AML constructs.
95 * Currently, these features are enabled by this flag:
97 * 1) Allow "implicit return" of last value in a control method
98 * 2) Allow access beyond the end of an operation region
99 * 3) Allow access to uninitialized locals/args (auto-init to integer 0)
100 * 4) Allow ANY object type to be a source operand for the Store() operator
101 * 5) Allow unresolved references (invalid target name) in package objects
102 * 6) Enable warning messages for behavior that is not ACPI spec compliant
104 ACPI_INIT_GLOBAL(u8, acpi_gbl_enable_interpreter_slack, FALSE);
107 * Automatically serialize all methods that create named objects? Default
108 * is TRUE, meaning that all non_serialized methods are scanned once at
109 * table load time to determine those that create named objects. Methods
110 * that create named objects are marked Serialized in order to prevent
111 * possible run-time problems if they are entered by more than one thread.
113 ACPI_INIT_GLOBAL(u8, acpi_gbl_auto_serialize_methods, TRUE);
116 * Create the predefined _OSI method in the namespace? Default is TRUE
117 * because ACPICA is fully compatible with other ACPI implementations.
118 * Changing this will revert ACPICA (and machine ASL) to pre-OSI behavior.
120 ACPI_INIT_GLOBAL(u8, acpi_gbl_create_osi_method, TRUE);
123 * Optionally use default values for the ACPI register widths. Set this to
124 * TRUE to use the defaults, if an FADT contains incorrect widths/lengths.
126 ACPI_INIT_GLOBAL(u8, acpi_gbl_use_default_register_widths, TRUE);
129 * Whether or not to validate (map) an entire table to verify
130 * checksum/duplication in early stage before install. Set this to TRUE to
131 * allow early table validation before install it to the table manager.
132 * Note that enabling this option causes errors to happen in some OSPMs
133 * during early initialization stages. Default behavior is to allow such
136 ACPI_INIT_GLOBAL(u8, acpi_gbl_enable_table_validation, TRUE);
139 * Optionally enable output from the AML Debug Object.
141 ACPI_INIT_GLOBAL(u8, acpi_gbl_enable_aml_debug_object, FALSE);
144 * Optionally copy the entire DSDT to local memory (instead of simply
145 * mapping it.) There are some BIOSs that corrupt or replace the original
146 * DSDT, creating the need for this option. Default is FALSE, do not copy
149 ACPI_INIT_GLOBAL(u8, acpi_gbl_copy_dsdt_locally, FALSE);
152 * Optionally ignore an XSDT if present and use the RSDT instead.
153 * Although the ACPI specification requires that an XSDT be used instead
154 * of the RSDT, the XSDT has been found to be corrupt or ill-formed on
155 * some machines. Default behavior is to use the XSDT if present.
157 ACPI_INIT_GLOBAL(u8, acpi_gbl_do_not_use_xsdt, FALSE);
160 * Optionally use 32-bit FADT addresses if and when there is a conflict
161 * (address mismatch) between the 32-bit and 64-bit versions of the
162 * address. Although ACPICA adheres to the ACPI specification which
163 * requires the use of the corresponding 64-bit address if it is non-zero,

165 * address. Default is FALSE, do not favor the 32-bit addresses.
167 ACPI_INIT_GLOBAL(u8, acpi_gbl_use32_bit_fadt_addresses, FALSE);

172 * if 64-bit FACS table address is selected:
173 * https://bugzilla.kernel.org/show_bug.cgi?id=74021
174 * Default is TRUE, favor the 32-bit addresses.
176 ACPI_INIT_GLOBAL(u8, acpi_gbl_use32_bit_facs_addresses, TRUE);
179 * Optionally truncate I/O addresses to 16 bits. Provides compatibility
180 * with other ACPI implementations. NOTE: During ACPICA initialization,
181 * this value is set to TRUE if any Windows OSI strings have been
182 * requested by the BIOS.
184 ACPI_INIT_GLOBAL(u8, acpi_gbl_truncate_io_addresses, FALSE);

190 ACPI_INIT_GLOBAL(u8, acpi_gbl_disable_auto_repair, FALSE);
