emulate illumos membar_producer with atomic_thread_fence_rel
membar_producer is supposed to be a store-store barrier. Also, in the code that FreeBSD has ported from illumos membar_producer is used only with regular stores to regular memory (with respect to caching). We do not have an MI primitive for the store-store barrier, so atomic_thread_fence_rel is the closest we have as it provides (load | store) -> store barrier. Previously, membar_producer was an empty function call on all 32-bit arm-s, 32-bit powerpc, riscv and all mips variants. I think that it was inadequate. On other platforms, such as amd64, arm64, i386, powerpc64, sparc64, membar_producer was implemented using stronger primitives than required for a store-store barrier with respect to regular memory access. For example, it used sfence on amd64 and lock-ed nop in i386 (despite TSO). On powerpc64 we now use recommended lwsync instead of eieio. On sparc64 FreeBSD uses TSO mode. On arm64/aarch64 we now use dmb sy instead of dmb ish. Not sure if this is an improvement, actually. After this change we can drop opensolaris_atomic.S for aarch64, amd64, powerpc64 and sparc64 as all required atomic operations have either direct or light-weight mapping to FreeBSD native atomic operations.

.Nd Super I/O controller and bus driver
|
||||
.Sh SYNOPSIS
|
||||
To compile this driver into the kernel,
|
||||
place the following line in your
|
||||
kernel configuration file:
|
||||
.Bd -ragged -offset indent
|
||||
.Cd "device superio"
|
||||
.Ed
|
||||
.Pp
|
||||
Alternatively, to load the driver as a
|
||||
module at boot time, place the following line in
|
||||
.Xr loader.conf 5 :
|
||||
.Bd -literal -offset indent
|
||||
superio_load="YES"
|
||||
.Ed
|
||||
.Sh DESCRIPTION
|
||||
Super I/O is an I/O controller that combines various low-bandwidth devices
|
||||
that can be functionally unrelated otherwise.
|
||||
A typical Super I/O can contain devices such as
|
||||
.Bl -bullet -compact
|
||||
.It
|
||||
a floppy disk controller
|
||||
.It
|
||||
a parallel port
|
||||
.It
|
||||
a serial port
|
||||
.It
|
||||
a PS/2 mouse and keyboard controller
|
||||
.It
|
||||
a hardware monitoring controller
|
||||
.It
|
||||
a watchdog timer
|
||||
.It
|
||||
a controller for general purpose input-output
|
||||
.El
|
||||
.Pp
|
||||
The
|
||||
.Nm
|
||||
driver provides support for devices residing in the Super I/O controller
|
||||
that can only be accessed or discovered using the controller's interface.
|
||||
Some of the Super I/O devices have standardized interfaces.
|
||||
Such devices either use well-known legacy resources or they are advertised
|
||||
via ACPI or both.
|
||||
They can be configured either using ISA bus hints or they are auto-aconfigured by
|
||||
.Xr acpi 4 .
|
||||
The
|
||||
.Nm
|
||||
driver is not designed to interact with that kind of devices.
|
||||
They can be handled by their respective drivers without any knowledge of the
|
||||
Super I/O specifics.
|
||||
For instance,
|
||||
.Xr fdc 4
|
||||
provides access to the floppy disk controller.
|
||||
.Pp
|
||||
There are other Super I/O devices that do not have any standardized interface.
|
||||
Drivers for those devices can be written using facilities of the
|
||||
.Nm
|
||||
driver.
|
||||
.Pp
|
||||
The driver itself attaches to the ISA bus as all supported controllers are
|
||||
accessed via LPC I/O ports.
|
||||
.Pp
|
||||
The
|
||||
.Nm
|
||||
driver is unusual as it is both a controller driver for a variety of Super I/O
|
||||
controllers and a bus driver for supported devices in those controllers.
|
||||
.Sh HARDWARE
|
||||
The
|
||||
.Nm
|
||||
driver supports a multitude of Super I/O controllers produced by Nuvoton,
|
||||
formerly known as Winbond, and ITE.

||||

The

||||
.Nm
|
||||
driver was written by
