-.Sh NAME
-.Nm pbio
-.Nd 8255 parallel peripheral interface basic
-.Tn I/O
-driver
-.Sh SYNOPSIS
-.Cd "device pbio"
-.Pp
-In
-.Pa /boot/device.hints :
-.Cd hint.pbio.0.at="isa"
-.Cd hint.pbio.0.port="0x360"
-.Pp
-.In dev/pbio/pbioio.h
-.Sh DESCRIPTION
-The
-.Nm
-driver supports direct access to the Intel 8255A programmable
-peripheral interface (PPI) chip running in mode 0 (simple
-.Tn I/O ) .
-Such an interface provides 24 digital
-.Tn I/O
-lines.
-The driver is designed for performing
-.Tn I/O
-under program control using
-peripherals such as the
-.Tn Advantech
-.Tn PCL-724
-card, which emulates the Intel 8255A PPI in mode 0.
-Other 8255A-based peripherals such as the
-.Tn BMC
-Messsysteme
-.Tn PIO24II
-card have also been reported to work.
-.Pp
-The PPI provides two 8-bit ports (port A and port B) and
-two 4-bit ports (port C upper, port C lower).
-Each port can be individually programmed for input and
-(latched) output,
-and appears at a different offset of the device's base
-.Tn I/O
-address.
-.Pp
-A separate register allows the configuration of ports for input
-or output.
-The device is so simple, that reliably probing for it when
-input data arrives at its terminals is impossible;
-therefore the kernel configuration has to specify the
-device's base address.
-The device driver provides four character devices that
-correspond to the peripheral's
-.Tn I/O
-ports.
-Opening a device for read or write automatically configures
-the corresponding hardware port for input or output.
-At boot time all ports are set configured for input to avoid damaging
-external circuitry.
-.Pp
-A set of
-.Xr ioctl 2
-requests allow polled input and paced output to be
-efficiently performed at the driver level without expensive
-user/kernel context switching.
-The driver can perform
-.Tn I/O
-in three different ways:
-.Bl -tag -width ".No Differential"
-.It Basic
-The read or write operation returns immediately after reading
-or writing the data to the port at bus speed.
-.It Paced
-Data is transferred from or to the port at intervals specified
-by a separate
-.Xr ioctl 2
-call.
-.It Differential
-(Input only.)
-Only port values that differ from the previous port value are returned.
-.El
-.Pp
-The pacing interval is specified in
-.Em Hz
-unit increments.
-Setting a pace of
-.Ar n
-seconds
-will result in no more than one value being read or written every
-.Ar n
-seconds.
-Single byte read/write operations will take at least
-.Ar n
-seconds to complete.
-.Pp
-The following
-.Xr ioctl 2
-calls are supported:
-.Bl -tag -width ".Dv PBIO_SETIPACE"
-.It Dv PBIO_SETDIFF
-accepts a pointer to an integer as the third argument,
-and sets the driver for differential input if the integer is non-zero.
-The input pace speed determines the periodic interval the driver will use to
-examine the port for a changed value.
-.It Dv PBIO_GETDIFF
-accepts a pointer to an integer as the third argument,
-and sets the integer to the last set value for differential input.
-.It Dv PBIO_SETIPACE
-accepts a pointer to an integer as the third argument,
-and sets the driver's input pacing speed to the value of that integer.
-.It Dv PBIO_GETIPACE
-accepts a pointer to an integer as the third argument,
-and sets the integer to the last set value for the input pace.
-.It Dv PBIO_SETOPACE
-accepts a pointer to an integer as the third argument,
-and sets the driver's output pacing speed to the value of that integer.
-.It Dv PBIO_GETOPACE
-accepts a pointer to an integer as the third argument,
-and sets the integer to the last set value for the output pace.
