125 * Enable "slack mode" of the AML interpreter? Default is FALSE, and the
126 * interpreter strictly follows the ACPI specification. Setting to TRUE
127 * allows the interpreter to ignore certain errors and/or bad AML constructs.
129 * Currently, these features are enabled by this flag:
131 * 1) Allow "implicit return" of last value in a control method
132 * 2) Allow access beyond the end of an operation region
133 * 3) Allow access to uninitialized locals/args (auto-init to integer 0)
134 * 4) Allow ANY object type to be a source operand for the Store() operator
135 * 5) Allow unresolved references (invalid target name) in package objects
136 * 6) Enable warning messages for behavior that is not ACPI spec compliant
138 ACPI_INIT_GLOBAL(u8, acpi_gbl_enable_interpreter_slack, FALSE);
141 * Automatically serialize all methods that create named objects? Default
142 * is TRUE, meaning that all non_serialized methods are scanned once at
143 * table load time to determine those that create named objects. Methods
144 * that create named objects are marked Serialized in order to prevent
145 * possible run-time problems if they are entered by more than one thread.
147 ACPI_INIT_GLOBAL(u8, acpi_gbl_auto_serialize_methods, TRUE);
150 * Create the predefined _OSI method in the namespace? Default is TRUE
151 * because ACPICA is fully compatible with other ACPI implementations.
152 * Changing this will revert ACPICA (and machine ASL) to pre-OSI behavior.
154 ACPI_INIT_GLOBAL(u8, acpi_gbl_create_osi_method, TRUE);
157 * Optionally use default values for the ACPI register widths. Set this to
158 * TRUE to use the defaults, if an FADT contains incorrect widths/lengths.
160 ACPI_INIT_GLOBAL(u8, acpi_gbl_use_default_register_widths, TRUE);
163 * Whether or not to validate (map) an entire table to verify
164 * checksum/duplication in early stage before install. Set this to TRUE to
165 * allow early table validation before install it to the table manager.
166 * Note that enabling this option causes errors to happen in some OSPMs
167 * during early initialization stages. Default behavior is to allow such
170 ACPI_INIT_GLOBAL(u8, acpi_gbl_enable_table_validation, TRUE);
173 * Optionally enable output from the AML Debug Object.
175 ACPI_INIT_GLOBAL(u8, acpi_gbl_enable_aml_debug_object, FALSE);
178 * Optionally copy the entire DSDT to local memory (instead of simply
179 * mapping it.) There are some BIOSs that corrupt or replace the original
180 * DSDT, creating the need for this option. Default is FALSE, do not copy
183 ACPI_INIT_GLOBAL(u8, acpi_gbl_copy_dsdt_locally, FALSE);
186 * Optionally ignore an XSDT if present and use the RSDT instead.
187 * Although the ACPI specification requires that an XSDT be used instead
188 * of the RSDT, the XSDT has been found to be corrupt or ill-formed on
189 * some machines. Default behavior is to use the XSDT if present.
191 ACPI_INIT_GLOBAL(u8, acpi_gbl_do_not_use_xsdt, FALSE);
194 * Optionally support group module level code.
196 ACPI_INIT_GLOBAL(u8, acpi_gbl_group_module_level_code, TRUE);
199 * Optionally support module level code by parsing the entire table as
200 * a term_list. Default is FALSE, do not execute entire table until some
201 * lock order issues are fixed.
203 ACPI_INIT_GLOBAL(u8, acpi_gbl_parse_table_as_term_list, FALSE);
206 * Optionally use 32-bit FADT addresses if and when there is a conflict
207 * (address mismatch) between the 32-bit and 64-bit versions of the
208 * address. Although ACPICA adheres to the ACPI specification which
209 * requires the use of the corresponding 64-bit address if it is non-zero,
210 * some machines have been found to have a corrupted non-zero 64-bit
211 * address. Default is FALSE, do not favor the 32-bit addresses.
213 ACPI_INIT_GLOBAL(u8, acpi_gbl_use32_bit_fadt_addresses, FALSE);
216 * Optionally use 32-bit FACS table addresses.
217 * It is reported that some platforms fail to resume from system suspending
218 * if 64-bit FACS table address is selected:
219 * https://bugzilla.kernel.org/show_bug.cgi?id=74021
220 * Default is TRUE, favor the 32-bit addresses.
222 ACPI_INIT_GLOBAL(u8, acpi_gbl_use32_bit_facs_addresses, TRUE);
225 * Optionally truncate I/O addresses to 16 bits. Provides compatibility
226 * with other ACPI implementations. NOTE: During ACPICA initialization,
227 * this value is set to TRUE if any Windows OSI strings have been
228 * requested by the BIOS.
230 ACPI_INIT_GLOBAL(u8, acpi_gbl_truncate_io_addresses, FALSE);

236 ACPI_INIT_GLOBAL(u8, acpi_gbl_disable_auto_repair, FALSE);
239 * Optionally do not install any SSDTs from the RSDT/XSDT during initialization.
240 * This can be useful for debugging ACPI problems on some machines.
242 ACPI_INIT_GLOBAL(u8, acpi_gbl_disable_ssdt_table_install, FALSE);
