Summary of changes for version 20190405: + + +1) ACPICA kernel-resident subsystem: + +Event Manager: History: Commit 18996f2db918 ("ACPICA: Events: Stop +unconditionally clearing ACPI IRQs during suspend/resume") was added +earlier to stop clearing of event status bits unconditionally on suspend +and resume paths. Though this change fixed an issue on suspend path, it +introduced regressions on several resume paths. In the case of S0ix, +events are enabled as part of device suspend path. If status bits for the +events are set when they are enabled, it could result in premature wake +from S0ix. If status is cleared for any event that is being enabled so +that any stale events are cleared out. In case of S0ix, events are +enabled as part of device suspend path. If status bits for the events are +set when they are enabled, it could result in premature wake from S0ix. + +This change ensures that status is cleared for any event that is being +enabled so that any stale events are cleared out. + + +2) iASL Compiler/Disassembler and ACPICA tools: + +iASL: Implemented an enhanced multiple file compilation that combines +named objects from all input files to a single namespace. With this +feature, any unresolved external declarations as well as duplicate named +object declarations can be detected during compilation rather than +generating errors much later at runtime. The following commands are +examples that utilize this feature: + iasl dsdt.asl ssdt.asl + iasl dsdt.asl ssdt1.asl ssdt2.asl + iasl dsdt.asl ssdt*.asl + +---------------------------------------- 29 March 2019.
