.Sh DESCRIPTION
The
.Nm
driver provides support for the EBus controller and bus found in most
.Tn PCI
based
.Tn UltraSPARC
systems.
The
.Tn EBus
bus is designed to provide the ability to put
.Tn ISA
and traditional
.Tn Intel
style peripherals in a
.Tn SPARC
based system with a minimal amount of glue logic.
In
.Tn UltraSPARC
systems it is implemented with either a PCIO or a PCIO-2 chip from
.Tn Sun Microelectronics .
The PCIO chip also implements a
.Xr hme 4
compatible
.Tn PCI
network device.
The PCIO-2 chip also implements a
.Xr fwohci 4
compatible
.Tn IEEE
.Tn 1394
.Tn OHCI
interface, a
.Xr gem 4
compatible
.Tn PCI
network device and an
.Xr ohci 4
compatible
.Tn OHCI
.Tn USB
controller.
The
.Tn EBus
has four DMA channels,
similar to the DMA seen in the
.Xr esp 4
.Tn SCSI
DMA.

.Cd "device mk48txx"
.Cd "device eeprom"
.Sh DESCRIPTION
The
.Nm
driver is a front-end for the machine-independent
.Tn Mostek
MK48Txx driver.
The
.Tn Mostek
MK48Txx driver provides access to the real time clock part of the chips it
supports to
.Fx
by interfacing with the generic clock code.
.Pp
.Tn Mostek
MK48Txx chips are found on the
.Tn EBus ,
.Tn FireHose
and
.Tn SBus
busses of
.Tn UltraSPARC
systems.
On systems where the hostid is stored in the NVRAM part of the Mostek MK48Txx
chip the
.Nm
driver prints out the hostid on attach.
.Sh DIAGNOSTICS
The following driver specific error message may be reported:
.Bl -diag
.It "mk48txx_attach: battery low"
The device signals that its battery is low and should be replaced.
The
.Nm
driver refused to attach the device in this case as the time in the real time
clock is probably invalid.
This gives the generic clock code the chance to use another device as the
system real time clock that otherwise would not have been chosen.

.Nm ofw_console
.Nd "Open Firmware console"
.Sh SYNOPSIS
.Cd "device ofw_console"
.Cd "options OFWCONS_POLL_HZ=N"
.Pp
.Cd "options KDB"
.Cd "options DDB"
.Cd "options ALT_BREAK_TO_DEBUGGER"
.Sh DESCRIPTION
The
.Nm
driver provides a simple text console,
using the Open Firmware services for input and output.
It will use the Open Firmware console devices set via the
.Va input-device
and
.Va output-device
variables.
.Pp
This driver is deprecated and only provided as a fallback console mechanism
if the real console hardware can not be driven by
.Fx .
.Pp
In case the
.Nm
console appears to work too slowly, its responsiveness probably can be improved
by including
.Cd "options OFWCONS_POLL_HZ=N" .
When ommitted,
.Dv OFWCONS_POLL_HZ
defaults to 4.
For example, on
.Tn Sun Ultra 2
a value of 20 or higher works best.
Too high values, on the other hand, can cause
.Nm
to unnecessarily consume CPU.
.Sh FILES

.It Pa /dev/keyboard
terminal input device in case the console input device is the keyboard
.It Pa /dev/screen
terminal output device in case the console output device is the screen
.It Pa /dev/tty[a-z]
terminal device in case both the console input and output device is tty[a-z]
.El
.Sh CAVEATS
Since the Open Firmware will handle BREAK
(or Stop-A)
sequences before
.Nm ,
the preferred way to enter
.Xr ddb 4
when using
.Nm
is to include
.Cd "options ALT_BREAK_TO_DEBUGGER"
in a ddb-enabled kernel, and enter the alternate BREAK sequence
(RETURN TILDE CTRL-b).
.Sh SEE ALSO
.Xr creator 4 ,
.Xr machfb 4 ,

.Sh HISTORY
The
.Nm
driver first appeared in
.Fx 5.0 .
.Sh AUTHORS
The
.Nm
driver was written by
.An "Benno Rice" Aq benno@FreeBSD.org .
.Sh BUGS
The
.Nm
driver
is not a real
.Xr tty 4
driver and is not MPSAFE.
The
.Nm
driver also does not attach to the hardware resources it actually talks to.
Therefore it cannot be included in the kernel together with real console
hardware drivers
like
.Xr creator 4 ,
.Xr machfb 4
and
.Xr uart 4 .

.Dt OPENFIRM 4 sparc64
.Os
.Sh NAME
.Nm openfirm
.Nd "Open Firmware interface"
.Sh SYNOPSIS
.In sys/types.h
.In sys/ioctl.h
.In dev/ofw/openfirmio.h
.Sh DESCRIPTION
The
.Pa /dev/openfirm
device is an interface to the
.Tn Open Firmware
device tree.
This interface is similar to the
.Tn SunOS /
.Tn Solaris
compatible
.Xr openprom 4
interface and highly stylized.
It uses
.Xr ioctl 2
calls for all operations.
These calls refer to the nodes in the
.Tn Open Firmware
device tree.
The nodes are represented by package handles,
which are simply integer values describing data areas.
Occasionally a package handle of 0 may be used or returned instead,
as described below.
.Pp
The calls that only take and/or return the package handle of a node
use a pointer to a
.Vt phandle_t
for this purpose.
The others use a pointer to a
.Vt "struct ofiocdesc"
descriptor,
which has the following definition:
.Bd -literal
struct ofiocdesc {
phandle_t of_nodeid;
int of_namelen;
const char *of_name;
int of_buflen;
char *of_buf;
};
.Ed
.Pp
The
.Va of_nodeid
member is the package handle of the node that is passed in or returned.
Strings are passed in via the
.Va of_name
member of
.Va of_namelen
length.
The maximum accepted length of
.Va of_name
is
.Dv OFIOCMAXNAME .
The
.Va of_buf
member is used to return strings except for the
.Dv OFIOCSET
call where it is also used to pass in a string.
In the latter case the maximum accepted length of
.Va of_buf
is
.Dv OFIOCMAXVALUE .
Generally,
.Va of_buf
works in a value-result fashion.
At entry to the
.Xr ioctl 2
call,
.Va of_buflen
is expected to reflect the buffer size.
On return,
.Va of_buflen
is updated to reflect the buffer contents.
.Pp
The following
.Xr ioctl 2
calls are supported:
.Bl -tag -width ".Dv OFIOCGETOPTNODE"
.It Dv OFIOCGETOPTNODE
Uses a
.Vt phandle_t .
Takes nothing and returns the package handle of the
.Pa /options
node.
.It Dv OFIOCGETNEXT
Uses a
.Vt phandle_t .
Takes the package handle of a node and returns the package handle of the next
node in the
.Tn Open Firmware
device tree.
The node following the last node has a package handle of 0.
The node following the node with the package handle of 0 is the first node.
.It Dv OFIOCGETCHILD
Uses a
.Vt phandle_t .
Takes the package handle of a node and returns the package handle of the first
child of that node.
This child may have siblings.
These can be determined by using
.Dv OFIOCGETNEXT .
If the node does not have a child,
a package handle of 0 is returned.
.It Dv OFIOCGET
Uses a
.Vt "struct ofiocdesc" .
Takes the package handle of a node and the name of a property.
Returns the property value and its length.
If no such property is associated with that node,
the length of the value is set to \-1.
If the named property exists but has no value,
the length of the value is set to 0.
.It Dv OFIOCGETPROPLEN
Uses a
.Vt "struct ofiocdesc" .
Takes the package handle of a node and the name of a property.
Returns the length of the property value.
This call is the same as
.Dv OFIOCGET
except that only the length of the property value is returned.
It can be used to determine whether a node has a particular property or whether
a property has a value without the need to provide memory for storing the value.
.It Dv OFIOCSET
Uses a
.Vt "struct ofiocdesc" .
Takes the package handle of a node,
the name of a property and a property value.
Returns the property value and the length that actually have been written.
The
.Tn Open Firmware
may choose to truncate the value if it is too long or write a valid value
instead if the given value is invalid for the particular property.
Therefore the returned value should be checked.
The
.Tn Open Firmware
may also completely refuse to write the given value to the property.
In this case
.Er EINVAL
is returned.
.It Dv OFIOCNEXTPROP
Uses a
.Vt "struct ofiocdesc" .
Takes the package handle of a node and the name of a property.
Returns the name and the length of the next property of the node.
If the property referenced by the given name is the last property of the node,
.Er ENOENT
is returned.
.It Dv OFIOCFINDDEVICE
Uses a
.Vt "struct ofiocdesc" .
Takes the name or alias name of a device node.
Returns package handle of the node.
If no matching node is found,
.Er ENOENT
is returned.

The

compatible interface to the
.Tn Open Firmware
device tree.
This interface is similar to the
.Xr openprom 4
interface.
It uses
.Xr ioctl 2
calls for all operations.
These calls refer to the nodes in the
.Tn Open Firmware
device tree.
However,
.Fx
only implements a subset of the
.Xr ioctl 2
calls
.Tn SunOS /
.Tn Solaris
does.
The nodes are represented by integer values,
which are simply describing data areas.
Occasionally the number 0 may be used or returned instead,
as described below.
.Pp
All calls use a pointer to a
.Vt "struct openpromio"
descriptor,
which has the following definition:
.Bd -literal
struct openpromio {
uint32_t oprom_size;
char oprom_array[];
};
.Ed
.Pp
The
.Va oprom_size
member refers to the size of
.Va oprom_array .
The
.Va oprom_array
member actually works like a union.
Depending on the
.Xr ioctl 2
call and whether the
.Vt "struct openpromio"
is used to pass in or return data,
.Va oprom_array
either contains an integer refereing to a node or a string refering to a
property name or property value.
The maximum size of
.Va oprom_array
is
.Dv OPROMMAXPARAM .
.Pp
The following
.Xr ioctl 2
calls are currently implemented:
.Bl -tag -width ".Dv OPROMGETPROP"
.It Dv OPROMNEXT
Takes the number of a node and returns the number of the next node in the
.Tn Open Firmware
device tree.
The node following the last node is number 0.
The node following number 0 is the first node.
.It Dv OPROMCHILD
Takes the number of a node and returns the number of the first child of that
node.
This child may have siblings.
These can be determined by using
.Dv OPROMNEXT .
If the node does not have a child,
0 is returned.
.It Dv OPROMGETPROP
Takes the name of a property.
Returns the property value.
The
.Dv OPROMGETPROP
call refers to the node previously returned by either the
.Dv OPROMNEXT
or the
.Dv OPROMCHILD
call,
depending on which one was invoked last.
If the property referenced by the given name is not associated with that node,
.Er EINVAL
is returned.
If the named property exists but has no value,
an empty string is returned.
.It Dv OPROMNXTPROP
Takes the name of a property.
Returns the name of the next property of the node.
As with the
.Dv OPROMGETPROP
call,
the
.Dv OPROMNXTPROP
call refers to the node previously returned by either the
.Dv OPROMNEXT
or the
.Dv OPROMCHILD
call.
If the property referenced by the given name is the last property of the node,
an empty string is returned.

The

.Sh DESCRIPTION
The

driver is a front-end for the machine-independent
.Tn Motorola
MC146818 and compatible clocks driver.
The
.Tn Motorola
MC146818 and compatible clocks driver provides access to the real time clock
part of the chips it supports to

by interfacing with the generic clock code.
.Pp
.Tn Dallas /
.Tn Maxim Semiconductor

systems and the EBus bus of
.Tn UltraSPARC III
systems.
.Sh DIAGNOSTICS
The following driver specific error message may be reported:
.Bl -diag
.It "mc146818_attach_attach: battery low"
The device signals that its battery is low and should be replaced.
The
.Nm
driver refused to attach the device in this case as the time in the real time
clock is probably invalid.
This gives the generic clock code the chance to use another device as the
system real time clock that otherwise would not have been chosen.
