2019-10-28ACPICA: make acpi_load_table() return table indexNikolaus Voss1-1/+2
ACPICA commit d1716a829d19be23277d9157c575a03b9abb7457 For unloading an ACPI table, it is necessary to provide the index of the table. The method intended for dynamically loading or hotplug addition of tables, acpi_load_table(), should provide this information via an optional pointer to the loaded table index. This patch fixes the table unload function of acpi_configfs.

2019-02-18ACPICA: Remove legacy module-level code supportErik Schmauss1-8/+0
ACPICA commit 47f5607c204719d9239a12b889df725225098c8f Module-level code refers to executable ASL code that runs during table load. This is typically used in ASL to declare named objects based on a condition evaluated during table load like so: definition_block(...) { opreation_region (OPR1, system_memory, ...) Field (OPR1) { FLD1, 8 /* Assume that FLD1's value is 0x1 */ } /* The if statement below is referred to as module-level code */ If (FLD1) { /* Declare DEV1 conditionally */ Device (DEV1) {...} } Device (DEV2) { ... } } In legacy module-level code, the execution of the If statement was deferred after other modules were loaded. The order of code execution for the table above is the following: 1.) Load OPR1 to the ACPI Namespace 2.) Load FLD1 to the ACPI Namespace (not intended for drivers) 3.) Load DEV2 to the ACPI Namespace 4.) Execute If (FLD1) and load DEV1 if the condition is true This legacy approach can be problematic for tables that look like the following: definition_block(...) { opreation_region (OPR1, system_memory, ...) Field (OPR1) { FLD1, 8 /* Assume that FLD1's value is 0x1 */ } /* The if statement below is referred to as module-level code */ If (FLD1) { /* Declare DEV1 conditionally */ Device (DEV1) {...} } Scope (DEV1) { /* Add objects DEV1's scope */ Name (OBJ1, 0x1234) } } When loading this in the legacy approach, Scope DEV1 gets evaluated before the If statement. The following is the order of execution: 1.) Load OPR1 to the ACPI Namespace 2.) Load FLD1 to the ACPI Namespace (not intended for drivers) 3.) Add OBJ1 under DEV1's scope -- ERROR. DEV1 does not exist 4.) Execute If (FLD1) and load DEV1 if the condition is true The legacy approach can never succeed for tables like this due to the deferral of the module-level code. Due to this limitation, a new module-level code was developed. This new approach exeutes if statements in the order that they appear in the definition block. With this approach, the order of execution for the above defintion block is as follows: 1.) Load OPR1 to the ACPI Namespace 2.) Load FLD1 to the ACPI Namespace (not intended for drivers) 3.) Execute If (FLD1) and load DEV1 because the condition is true 4.) Add OBJ1 under DEV1's scope. Since DEV1 is loaded in the namespace in step 3, step 4 executes successfully. This change removes support for the legacy module-level code execution. From this point onward, the new module-level code execution will be the official approach.

2018-10-18ACPICA: Remove acpi_gbl_group_module_level_code and only use acpi_gbl_execute_tables_as_methods insteadErik Schmauss1-7/+0
acpi_gbl_group_module_level_code and acpi_gbl_execute_tables_as_methods were used to enable different table load behavior. The different table load behaviors are as follows: A.) acpi_gbl_group_module_level_code enabled the legacy approach where ASL if statements are executed after the namespace object has been loaded. B.) acpi_gbl_execute_tables_as_methods is currently used to enable the table load to be a method invocation. This meaning that ASL If statements are executed in-line rather than deferred until after the ACPI namespace has been populated. This is the correct behavior and option A will be removed in the future. We do not support a table load behavior where these variables are assigned the same value. In otherwords, we only support option A or B and do not need acpi_gbl_group_module_level_code to enable A. From now on, acpi_gbl_execute_tables_as_methods == 0 enables option A and acpi_gbl_execute_tables_as_methods == 1 enables option B. Note: option A is expected to be removed in the future and option B will become the only supported table load behavior. Signed-off-by: Erik Schmauss <erik.schmauss@intel.com> Signed-off-by: Rafael J.

2018-02-21ACPICA: Integrate package handling with module-level codeSchmauss, Erik1-2/+6
ACPICA commit 8faf6fca445eb7219963d80543fb802302a7a8c7 This change completes the integration of the recent changes to package object handling with the module-level code support. For acpi_exec, the -ep flag is removed. This change allows table load to behave as if it were a method invocation. Before this, the definition block definition below would have loaded all named objects at the root scope. After loading, it would execute the if statements at the root scope. DefinitionBlock (...) { Name(OBJ1, 0) if (1) { Device (DEV1) { Name (_HID,0x0) } } Scope (DEV1) { Name (OBJ2) } } The above code would load OBJ1 to the namespace, defer the execution of the if statement and attempt to add OBJ2 within the scope of DEV1. Since DEV1 is not in scope, this would incur an AE_NOT_FOUND error. After this error is emitted, the if block is invoked and DEV1 and its _HID is added to the namespace. This commit changes the behavior to execute the if block in place rather than deferring it until all tables are loaded. The new behavior is as follows: insert OBJ1 in the namespace, invoke the if statement and add DEV1 and its _HID to the namespace, add OBJ2 to the scope of DEV1.

ACPICA commit 9605023e7e6d1f05581502766c8cf2905bcc03d9 This patch implements a new infinite loop detection mechanism to replace the old one, it uses acpi_os_get_timer() to limit loop execution into a determined time slice. This is useful in case some hardware/firmware operations really require the AML interpreter to wait while the old mechanism could expire too fast on recent machines. The new mechanism converts old acpi_gbl_max_loop_iterations to store the user configurable value for the new mechanism in order to allow users to be still able to configure this value for acpiexec via command line. This patch also removes wrong initilization code of acpi_gbl_max_loop_iterations accordingly (it should have been initialized by ACPI_INIT_GLOBAL, and the default value is also properly tuned for acpiexec).

ACPICA commit 3d837b5d4b1033942b4d91c7d3801a09c3157918 acpi_gbl_verify_table_checksum is used to avoid validating (mapping) an entire table in OS boot stage. 2nd "Reload" check in acpi_tb_install_standard_table() is prepared for the same purpose. So this patch combines them together using a renamed acpi_gbl_enable_table_validation flag. Lv Zheng.

2016-12-21ACPI / osl: Remove deprecated acpi_get_table_with_size()/early_acpi_os_unmap_memory()Lv Zheng1-13/+0
Since all users are cleaned up, remove the 2 deprecated APIs due to no users. As a Linux variable rather than an ACPICA variable, acpi_gbl_permanent_mmap is renamed to acpi_permanent_mmap to have a consistent coding style across entire Linux ACPI subsystem.

2016-12-21ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernelLv Zheng1-3/+9
ACPICA commit cac6790954d4d752a083e6122220b8a22febcd07 This patch back ports Linux acpi_get_table_with_size() and early_acpi_os_unmap_memory() into ACPICA upstream to reduce divergences. The 2 APIs are used by Linux as table management APIs for long time, it contains a hidden logic that during the early stage, the mapped tables should be unmapped before the early stage ends. During the early stage, tables are handled by the following sequence: acpi_get_table_with_size(); parse the table early_acpi_os_unmap_memory(); During the late stage, tables are handled by the following sequence: acpi_get_table(); parse the table Linux uses acpi_gbl_permanent_mmap to distinguish the early stage and the late stage. The reasoning of introducing acpi_get_table_with_size() is: ACPICA will remember the early mapped pointer in acpi_get_table() and Linux isn't able to prevent ACPICA from using the wrong early mapped pointer during the late stage as there is no API provided from ACPICA to be an inverse of acpi_get_table() to forget the early mapped pointer. But how ACPICA can work with the early/late stage requirement? Inside of ACPICA, tables are ensured to be remained in "INSTALLED" state during the early stage, and they are carefully not transitioned to "VALIDATED" state until the late stage. So the same logic is in fact implemented inside of ACPICA in a different way. The gap is only that the feature is not provided to the OSPMs in an accessible external API style. It then is possible to fix the gap by providing an inverse of acpi_get_table() from ACPICA, so that the two Linux sequences can be combined: acpi_get_table(); parse the table acpi_put_table(); In order to work easier with the current Linux code, acpi_get_table() and acpi_put_table() is implemented in a usage counting based style: 1. When the usage count of the table is increased from 0 to 1, table is mapped and .Pointer is set with the mapping address (VALIDATED); 2. When the usage count of the table is decreased from 1 to 0, .Pointer is unset and the mapping address is unmapped (INVALIDATED). So that we can deploy the new APIs to Linux with minimal effort by just invoking acpi_get_table() in acpi_get_table_with_size() and invoking acpi_put_table() in early_acpi_os_unmap_memory().
