xen/intr: correct misuses of Xen handle pointer type

2023-11-28T11:51:19+00:00

Fix a few spots where handle pointers were incorrectly used.  Luckily
these appear rarely triggered given how long they've been lurking.

Fixes: 76acc41fb7c7 ("Implement vector callback for PVHVM and unify event channel implementations")
Fixes: 9f40021f288c ("Introduce a new, HVM compatible, paravirtualized timer driver for Xen.")

spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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

xen/timer: rename "timer.c" to "xen_timer.c"

2023-02-05T17:50:50+00:00

The better to avoid conflicting with other files given how "timer.c"
isn't a very unique name.  ARM and RISC-V both have timer.c files.

xen: Use devclass_find to lookup devclasses in identify.

2022-04-25T18:55:30+00:00

While here, use driver->name instead of hardcoding the xenpv and
xen_et strings both for devclass_find() and BUS_ADD_CHILD().

xen: switch to use headers in contrib

2022-02-07T09:11:56+00:00

These headers originate with the Xen project and shouldn't be mixed with
the main portion of the FreeBSD kernel. Notably they shouldn't be the
target of clean-up commits.

Switch to use the headers in sys/contrib/xen.

Make timespecadd(3) and friends public

2018-07-30T15:46:40+00:00

The timespecadd(3) family of macros were imported from NetBSD back in
r35029. However, they were initially guarded by #ifdef _KERNEL. In the
meantime, we have grown at least 28 syscalls that use timespecs in some
way, leading many programs both inside and outside of the base system to
redefine those macros. It's better just to make the definitions public.

Our kernel currently defines two-argument versions of timespecadd and
timespecsub.  NetBSD, OpenBSD, and FreeDesktop.org's libbsd, however, define
three-argument versions.  Solaris also defines a three-argument version, but
only in its kernel.  This revision changes our definition to match the
common three-argument version.

Bump _FreeBSD_version due to the breaking KPI change.
