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.

spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

2023-05-12T16:44:03+00:00

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

pbio: Remove unused devclass argument to DRIVER_MODULE.

pbio: Add locking and remove D_NEEDGIANT.

2022-05-05T23:40:04+00:00

Use a sx lock to permit uiomove directly into/out of the the per-port
buffers.  In addition, the sx lock provides a stronger guarantee that
I think this driver wants which is to single-thread read and write
calls even while paused.  Finally, replace tsleep with dummy wait
channels with calls to pause_sig to more clearly communicate the
intent.

pbio: Return BUS_PROBE_DEFAULT from probe instead of 0.

2022-05-05T23:39:19+00:00

0 should only be returned from probe in legacy drivers that need to
preserve softc state between probe and attach.

pbio: Store softc in si_drv1 for character devices.

2022-05-05T23:38:25+00:00

The port number is still stored in the unit (si_drv0) but is the
entire unit value now.

While here, removed checks for NULL softc since those can never happen
from cdevsw routines.  This also resulted in the close method becoming
a no-op, so it has been removed.
