The branch main has been updated by mhorne: URL: https://cgit.FreeBSD.org/src/commit/?id=1d03c3578d05b011dc714ec0735a5783c421530b commit 1d03c3578d05b011dc714ec0735a5783c421530b Author: Mitchell Horne <mhorne@FreeBSD.org> AuthorDate: 2021-12-05 15:27:50 +0000 Commit: Mitchell Horne <mhorne@FreeBSD.org> CommitDate: 2023-02-08 20:50:46 +0000 arm: add an interrupt rman to nexus Allow the nexus bus to own and manage interrupt resources. Currently, interrupt resources on this architecture are managed completely by ofwbus, but it is desirable that system-wide memory and interrupt resources be managed by the top-level bus. This is a pre-requisite to moving this resource management out of ofwbus.
