chore: replace {0, 0} with {DEV,KOBJ}METHOD_END

2026-02-25T05:59:34+00:00

Both of the aforementioned macros have been present in FreeBSD
for well over a decade: 2009 for `KOBJMETHOD_END`; 2011 for
`DEVMETHOD_END`.

Adapt all hardcoded references of `{0, 0}` with `DEVMETHOD_END`
and `KOBJMETHOD_END` as appropriate. This helps ensure that
future adaptations to drivers following patterns documented
in driver(9) can be made more easily/without issue.

bus: Document special ranges of IVARs

2026-02-17T20:45:13+00:00

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.

Use bus_generic_detach instead of device_delete_children in detach

2025-01-02T18:24:28+00:00

While here, check for errors from bus_generic_detach and move it to
the start of detach if necessary.

bus_generic_detach: Delete children after detaching them

2025-01-02T18:21:30+00:00

This provides better semantics as a standalone DEVMETHOD for
device_attach as bus drivers should remove child devices they created
as part of detach cleanup.  The implementation calls
bus_detach_children() first to permit child devices an opportunity to
veto the detach operation.  If that succeeds, device_delete_children()
is used to delete the child devices.

This requires fixing various drivers that were deleting devices
explicitly (via a device_t pointer cached in the softc) after calling
bus_generic_detach to stop doing that and just rely on
bus_generic_detach to remove child devices.
