src/sys/dev/puc, branch main FreeBSD source tree bus: Document special ranges of IVARs 2026-02-17T20:45:13+00:00 John Baldwin jhb@FreeBSD.org 2026-02-17T20:45:13+00:00 6cf4e30252fe48b230b9d76cac20576d5b3d2ffa 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.
