The branch releng/14.2 has been updated by cperciva: URL: https://cgit.FreeBSD.org/src/commit/?id=4b4c7b1924004e53f501612c7ad97b860644e583 commit 4b4c7b1924004e53f501612c7ad97b860644e583 Author: Andrew Turner <andrew@FreeBSD.org> AuthorDate: 2024-10-29 10:19:45 +0000 Commit: Colin Percival <cperciva@FreeBSD.org> CommitDate: 2024-11-03 16:15:34 +0000 bus: Activate INTRNG interrupts in common code [MFC note: This is not a direct cherry-pick due to API changes in HEAD which are not present in stable/14.] We need to call into INTRNG to activate all interrupts on platforms that use it. Currently, interrupts are only activated in the nexus drivers for INTRNG platforms, but this does not handle other bus devices such as gpiobus that manage their own IRQ space.
