The driver provides support for Human Interface Devices (HID) on
Serial Peripheral Interface (SPI) buses on Apple Intel Macs
produced in 2015-2018.
The driver appears to work more stable after installation of Darwin OSI
in acpi(4) driver.
To install Darwin OSI insert following lines into /boot/loader.conf:
hw.acpi.install_interface="Darwin"
hw.acpi.remove_interface="Windows 2009, Windows 2012"

The event channel source code or equivalent is needed on all
architectures. Since much of this is viable to share, get this moved out
of x86-land. Each interrupt interface then needs a distinct back-end
implementation.

xen_intr_handle_upcall() has two interfaces. It needs to be called by
the x86 assembly code invoked by the APIC. Second, it needs to be called
as a driver_filter_t for the XenPCI code and for architectures besides
x86.
Unfortunately the driver_filter_t interface was implemented as a wrapper
around the x86-APIC interface. Now create a simple wrapper for the
x86-APIC code, which calls an architecture-independent
xen_intr_handle_upcall().
When called via intr_event_handle(), driver_filter_t functions expect
preemption to be disabled. This removes the need for
critical_enter()/critical_exit() when called this way.
The lapic_eoi() call is only needed on x86 in some cases when invoked
directly as an APIC vector handler.
Additionally driver_filter_t functions have no need to handle interrupt
counters. The intrcnt_add() calling function was reworked to match the
current situation. intrcnt_add() is now only called via one path.
The increment/decrement of curthread->td_intr_nesting_level had
previously been left out. Appears this was mostly harmless, but this
was noticed during implementation and has been added.
CONFIG_X86 is a leftover from use with Linux. While the barrier isn't
needed for FreeBSD on x86, it will be needed for FreeBSD on other
architectures.
Copyright note. xen_intr_intrcnt_add() was introduced at 76acc41fb7
by Justin T. Gibbs. xen_intrcnt_init() was introduced at fd036deac1
by John Baldwin.
sys/x86/xen/xen_arch_intr.c was originally created by Julien Grall in
2015 for the purpose of holding the x86 interrupt interface. Later it
was found xen_intr_handle_upcall() was better earlier, and the x86
interrupt interface better later. As such the filename and header list
belong to Julien Grall, but what those were created for is later.

All supported Xen instances by FreeBSD provide a local APIC
implementation, so there's no need to replace the native local APIC
implementation anymore.
Leave just the ipi_vectored hook in order to be able to override it
with an implementation based on event channels if the underlying local
APIC is not virtualized by hardware. Note the hook cannot use ifuncs,
because at the point where ifuncs are resolved the kernel doesn't yet
know whether it will benefit from using the optimization.

The last two drivers that required sppp are cp(4) and ce(4).
These devices are still produced and can be purchased
at Cronyx <http://cronyx.ru/hardware/wan.html>.
Since Roman Kurakin <rik@FreeBSD.org> has quit them, they no
longer support FreeBSD officially. Later they have dropped
support for Linux drivers to. As of mid-2020 they don't even
have a developer to maintain their Windows driver. However,
their support verbally told me that they could provide aid to
a FreeBSD developer with documentaion in case if there appears
a new customer for their devices.
These drivers have a feature to not use sppp(4) and create an
interface, but instead expose the device as netgraph(4) node.
Then, you can attach ng_ppp(4) with help of ports/net/mpd5 on
top of the node and get your synchronous PPP. Alternatively
you can attach ng_frame_relay(4) or ng_cisco(4) for HDLC.
Actually, last time I used cp(4) back in 2004, using netgraph(4)
instead of sppp(4) was already the right way to do.
Thus, remove the sppp(4) related part of the drivers and enable
by default the negraph(4) part. Further maintenance of these
drivers in the tree shouldn't be a big deal.
While doing that, remove some cruft and enable cp(4) compilation
on amd64. The ce(4) for some unknown reason marks its internal
DDK functions with __attribute__ fastcall, which most likely is
safe to remove, but without hardware I'm not going to do that, so
ce(4) remains i386-only.
