[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v2 00/15] Allow x86 to unflatten DTs
v2 pipeline: https://gitlab.com/xen-project/people/agvallejo/xen/-/pipelines/1855777776 v1: https://lore.kernel.org/xen-devel/20250530120242.39398-1-agarciav@xxxxxxx/ Original cover letter: This is the aftermath of this discussion: https://lore.kernel.org/xen-devel/DA1WWRUQLCAG.ZTVR1HXJ85V0@xxxxxxx/https://lore.kernel.org/xen-devel/DA1WWRUQLCAG.ZTVR1HXJ85V0@xxxxxxx/ It's a first round of cleanup and preparation to have a much easier time later when integrating dom0less boot into hyperlaunch. The refactor on device-tree/ is _fine_ by I'm open to other suggestions to achieve the same thing. In particular, after this series x86 can unflatten the DT host device tree when it has CONFIG_DOM0LESS_BOOT set, which enables the builder to use factored-out functions from dom0less-build.c (not done here). The diffstat is deceptive because I renamed a large file and then created a new file with the same name. There aren't that many LoC changes.
