xen: remove PV suspend/resume support copyright

2024-10-07T16:59:45+00:00

Thew code for PV suspend/resume support has long been removed, also remove the
copyright notice associated with it.

There are still two copyright blocks with (to my understanding) slightly
different wordings of the BSD 2 clause license.  I however don't feel like
merging them due to those wording differences.

The removal of the PV suspend/resume code was done in
ed95805e90ec0f61683cd402a42e6f915339de7d.

xen: expose support for poweroff/reboot/suspend on xenbus

2024-10-07T16:59:45+00:00

Some toolstacks won't attempt the signal power actions on xenbus unless the VM
explicitly exposes support for them.  FreeBSD supports all power actions, hence
signal on xenbus such support by setting the nodes to the value of "1".

xen/dev: remove __unused from driver argument of identify functions

2023-11-28T12:32:57+00:00

The driver argument is most certainly now used by these functions.  When
originally implemented it might have been unused, but not now.

xen: improve shutdown hook

2023-11-23T16:07:42+00:00

Make better use of the shutdown flags. In particular this now handles
standard reboot where RB_POWERCYCLE is not set, and indicates a crash
when the system has panicked.

While here, give the function a prefix.

Adjust function definitions in xen's control.c to avoid clang 15 warnings

2022-07-26T17:59:55+00:00

With clang 15, the following -Werror warnings are produced:

    sys/dev/xen/control/control.c:188:15: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
    xctrl_poweroff()
                  ^
                   void
    sys/dev/xen/control/control.c:194:13: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
    xctrl_reboot()
                ^
                 void
    sys/dev/xen/control/control.c:207:14: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
    xctrl_suspend()
                 ^

    xctrl_crash()
               ^
                void

This is because xctrl_poweroff(), xctrl_reboot(), xctrl_suspend(), and
xctrl_crash() are declared with (void) argument lists, but defined with
empty argument lists. Make the definitions match the declarations.

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.
