* sys/modules: fix standalone build for multiple modulesShengYi Hung2025-08-231-0/+2
| | | | | | | | | 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
* modules: gpioaei: Fix arm64.LINT-FDT breakageRavi Pokala2024-11-021-0/+1
| | | | | | 'acpi_if.h' was accidentally omitted from the module Makefile; add it. Fixes: 9709bda03cd0
* modules: gpioaei only on ACPI-supporting archsColin Percival2024-10-311-1/+5
| | | | | | Fixes: 9709bda03cd0 ("GPIO: Add ACPI _AEI support") Pointy-hat to: cperciva Sponsored by: Amazon
* GPIO: Add ACPI _AEI supportColin Percival2024-10-312-1/+15
| | | | | | | | | | | | | | | | | | | 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.)

* When building modules, define make variable OPT_FDT if the kernel configIan Lepore2016-05-271-1/+5

In the past we've gotten away with using the arch name as a proxy for FDT support in makefile conditional logic, but now mips has some platforms with fdt support and some without and we need a more direct test.

This is primarily done to save a few bytes here and there on embedded systems with limited flash space for kernels - a very limited (sub-1MB) space may be available for the kernel and may only support gzip encoding. The rootfs can be LZMA compressed. Notes: svn path=/head/; revision=230150
