ACPICA 20050408 from Bob Moore Fixed three cases in the interpreter where an "index" argument to an ASL function was still (internally) 32 bits instead of the required 64 bits. This was the Index argument to the Index, Mid, and Match operators. The "strupr" function is now permanently local (acpi_ut_strupr), since this is not a POSIX-defined function and not present in most kernel-level C libraries. References to the C library strupr function have been removed from the headers. Completed the deployment of static functions/prototypes. All prototypes with the static attribute have been moved from the headers to the owning C file. ACPICA 20050329 from Bob Moore An error is now generated if an attempt is made to create a Buffer Field of length zero (A CreateField with a length operand of zero.) The interpreter now issues a warning whenever executable code at the module level is detected during ACPI table load. This will give some idea of the prevalence of this type of code. Implemented support for references to named objects (other than control methods) within package objects. Enhanced package object output for the debug object. Package objects are now completely dumped, showing all elements. Enhanced miscellaneous object output for the debug object. Any object can now be written to the debug object (for example, a device object can be written, and the type of the object will be displayed.) The "static" qualifier has been added to all local functions across the core subsystem. The number of "long" lines (> 80 chars) within the source has been significantly reduced, by about 1/3. Cleaned up all header files to ensure that all CA/iASL functions are prototyped (even static functions) and the formatting is consistent. Two new header files have been added, acopcode.h and acnames.h. Removed several obsolete functions that were no longer used. Signed-off-by: Len Brown <len.brown@intel.com>

ACPICA: Interpreter: Fix MLC issues by switching to new term_list grammar for table loading ACPICA commit 0e24fb67cde08d7df7671d7d7b183490dc79707e The MLC (Module Level Code) is an ACPICA terminology describing the AML code out of any control method, its support is an indication of the interpreter behavior during the table loading. The original implementation of MLC in ACPICA had several issues: 1. Out of any control method, besides of the object creating opcodes, only the code blocks wrapped by "If/Else/While" opcodes were supported. 2. The supported MLC code blocks were executed after loading the table rather than being executed right in place. ============================================================ The demo of this order issue is as follows: Name (OBJ1, 1) If (CND1 == 1) { Name (OBJ2, 2) } Name (OBJ3, 3) The original MLC support created OBJ2 after OBJ3's creation. ============================================================ Other than these limitations, MLC support in ACPICA looks correct. And supporting this should be easy/natural for ACPICA, but enabling of this was blocked by some ACPICA internal and OSPM specific initialization order issues we've fixed recently. The wrong support started from the following false bug fixing commit: Commit: 7f0c826a437157d2b19662977e9cf3b472cf24a6 Subject: ACPICA: Add support for module-level executable AML code Commit: 9a884ab64a4d092b4c3bf24fd9a30f7fbd4591e7 Subject: ACPICA: Add additional module-level code support ... We can confirm Windows interpreter behavior via reverse engineering means. It can be proven that not only If/Else/While wrapped code blocks, all opcodes can be executed at the module level, including operation region accesses. And it can be proven that the MLC should be executed right in place, not in such a deferred way executed after loading the table. And the above facts indeed reflect the spec words around ACPI definition block tables (DSDT/SSDT/...), the entire table and the Scope object is defined by the AML specification in BNF style as: AMLCode := def_block_header term_list def_scope := scope_op pkg_length name_string term_list The bodies of the scope opening terms (AMLCode/Scope) are all term_list, thus the table loading should be no difference than the control method evaluations as the body of the Method is also defined by the AML specification as term_list: def_method := method_op pkg_length name_string method_flags term_list The only difference is: after evaluating control method, created named objects may be freed due to no reference, while named objects created by the table loading should only be freed after unloading the table. So this patch follows the spec and the de-facto standard behavior, enables the new grammar (term_list) for the table loading. By doing so, beyond the fixes to the above issues, we can see additional differences comparing to the old grammar based table loading: 1. Originally, beyond the scope opening terms (AMLCode/Scope), If/Else/While wrapped code blocks under the scope creating terms (Device/power_resource/Processor/thermal_zone) are also supported as deferred MLC, which violates the spec defined grammar where object_list is enforced. With MLC support improved as non-deferred, the interpreter parses such scope creating terms as term_list rather object_list like the scope opening terms. After probing the Windows behavior and proving that it also parses these terms as term_list, we submitted an ECR (Engineering Change Request) to the ASWG (ACPI Specification Working Group) to clarify this. The ECR is titled as "ASL Grammar Clarification for Executable AML Opcodes" and has been accepted by the ASWG. The new grammar will appear in ACPI specification 6.2. 2. Originally, Buffer/Package/operation_region/create_XXXField/bank_field arguments are evaluated in a deferred way after loading the table. With MLC support improved, they are also parsed right in place during the table loading. This is also Windows compliant and the only difference is the removal of the debugging messages implemented before acpi_ds_execute_arguments(), see Link # [1] for the details. A previous commit should have ensured that acpi_check_address_range() won't regress. Note that enabling this feature may cause regressions due to long term Linux ACPI support on top of the wrong grammar. So this patch also prepares a global option to be used to roll back to the old grammar during the period between a regression is reported and the regression is root-cause-fixed. Lv Zheng.

Two new header files have been added, acopcode.h and acnames.h. Removed several obsolete functions that were no longer used. Signed-off-by: Len Brown <len.brown@intel.com>

* nseval - Namespace evaluation functions
*/
ACPI: ACPICA 20060526 Restructured, flattened, and simplified the internal interfaces for namespace object evaluation - resulting in smaller code, less CPU stack use, and fewer interfaces. (With assistance from Mikhail Kouzmich) Fixed a problem with the CopyObject operator where the first parameter was not typed correctly for the parser, interpreter, compiler, and disassembler. Caused various errors and unexpected behavior. Fixed a problem where a ShiftLeft or ShiftRight of more than 64 bits produced incorrect results with some C compilers. Since the behavior of C compilers when the shift value is larger than the datatype width is apparently not well defined, the interpreter now detects this condition and simply returns zero as expected in all such cases. (BZ 395) Fixed problem reports (Valery Podrezov) integrated: - Update String-to-Integer conversion to match ACPI 3.0A spec http://bugzilla.kernel.org/show_bug.cgi?id=5329 Allow interpreter to handle nested method declarations http://bugzilla.kernel.org/show_bug.cgi?id=5361 Fixed problem reports (Fiodor Suietov) integrated: - acpi_terminate() doesn't free debug memory allocation list objects (BZ 355) - After Core Subsystem shutdown, acpi_subsystem_status() returns AE_OK (BZ 356) - acpi_os_unmap_memory() for RSDP can be invoked inconsistently (BZ 357) - Resource Manager should return AE_TYPE for non-device objects (BZ 358) - Incomplete cleanup branch in AcpiNsEvaluateRelative (BZ 359) - Use acpi_os_free() instead of ACPI_FREE in acpi_rs_set_srs_method_data (BZ 360) - Incomplete cleanup branch in acpi_ps_parse_aml (BZ 361) - Incomplete cleanup branch in acpi_ds_delete_walk_state (BZ 362) - acpi_get_table_header returns AE_NO_ACPI_TABLES until DSDT is loaded (BZ 365) - Status of the Global Initialization Handler call not used (BZ 366) - Incorrect object parameter to Global Initialization Handler (BZ 367) Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

ACPICA 20050408 from Bob Moore Fixed three cases in the interpreter where an "index" argument to an ASL function was still (internally) 32 bits instead of the required 64 bits. This was the Index argument to the Index, Mid, and Match operators. The "strupr" function is now permanently local (acpi_ut_strupr), since this is not a POSIX-defined function and not present in most kernel-level C libraries. References to the C library strupr function have been removed from the headers. Completed the deployment of static functions/prototypes. All prototypes with the static attribute have been moved from the headers to the owning C file. ACPICA 20050329 from Bob Moore An error is now generated if an attempt is made to create a Buffer Field of length zero (A CreateField with a length operand of zero.) The interpreter now issues a warning whenever executable code at the module level is detected during ACPI table load. This will give some idea of the prevalence of this type of code. Implemented support for references to named objects (other than control methods) within package objects. Enhanced package object output for the debug object.
