bus: Document special ranges of IVARs

2026-02-17T20:45:13Z

Some IVAR indices are special in that they have global meaning across multiple buses where as other IVARs are always private to the local bus. Try to document this a bit and add constants for the various ranges to avoid future conflicts. This is a no-op, but IVAR indices are now generally defined as enums as that makes it easier to define them in terms of ranges.

sys: make the kernel metadata pointer global

2025-01-24T21:25:51Z

The way we got the kernel metadata pointer was by calling preload_search_by_type with one of the following three: "elf kernel", "elf32 kernel" and "elf64 kernel". Which one(s) we used wasn't consistent though. Sometimes we would only try "elf kernel", and other times we would try one of the latter two if the first failed. However, the loader only ever sets "elf kernel" as the kernel type. Now, the kmdp is a global, preload_kmdp, and it's initialized using preload_initkmdp in machdep.c (or machdep_boot.c on arm/64). preload_initkmdp takes a single boolean argument that tells us whether not finding the kmdp is fatal or not.
