sys/modules: fix standalone build for multiple modules

2025-08-23T04:58:40Z

Multiple Makefile miss opt_*.h and *_if.h header file. We fix it by running make in sys/modules to build all modules. Approved by: lwhsu (mentor), markj (mentor) Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D52062

GPIO: Add ACPI _AEI support

2024-10-31T21:26:34Z

Changes to acpi_gpiobus.c handle discovering and parsing the _AEI objects and storing necessary data in device ivars. A new gpioaei.c file implements the device, which simply requests an interrupt when the pin is triggered and invokes the appropriate _Exx or _Lxx ACPI method. This makes the GPIO "power button" work on arm64 Graviton systems, allowing EC2 "Stop"/"Reboot" instance calls to be handled cleanly. (Prior to this change, those requests would time out after 4 minutes and the instance would be forcibly killed.)
