* ACPICA: Add option to disable Package object name resolution errorsBob Moore2018-02-211-7/+31
| | | | | | | | | | | | | | | | | ACPICA commit a6c3c725c44dd44ad9d3f2b2a64351fdbe6e0014 For the kernel-resident ACPICA, optionally be silent about the NOT_FOUND case. Although this is potentially a serious problem, it can generate a lot of noise/errors on platforms whose firmware carries around a bunch of unused Package objects. To disable these errors, define ACPI_IGNORE_PACKAGE_RESOLUTION_ERRORS in the OS-specific header.

* ACPICA: Integrate package handling with module-level codeSchmauss, Erik2018-02-211-57/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Implement deferred resolution of reference package elementsBob Moore2017-08-031-0/+496
ACPICA commit 0c08790c56fdf0dc081ae869495a09d8c4230854 This change defers the resolution of package elements that are named references until after the entire namespace has been loaded from the definition block. This allows such references to be in fact forward references for both module level code and control methods.
