The branch main has been updated by obiwac: URL: https://cgit.FreeBSD.org/src/commit/?id=c0df8f6f0e6a5f77ec9140e8075d09c55fe4c3c7 commit c0df8f6f0e6a5f77ec9140e8075d09c55fe4c3c7 Author: Aymeric Wibo <obiwac@FreeBSD.org> AuthorDate: 2025-12-29 20:01:50 +0000 Commit: Aymeric Wibo <obiwac@FreeBSD.org> CommitDate: 2026-01-08 10:35:54 +0000 acpi: Make taskqueue only run on BSP This is needed because when we add the suspend-to-idle loop, we only want to break the BSP out of idle to process the taskqueue while keeping all the others idled. Currently assuming BSP to be CPU0, which may not always be the case on non-x86.
