config info. from device.hints. Some machines have ipmi controllers that do not have attachment info in either PCI, SMBIOS or ACPI. This idea was hacked together by me and then done properly by jhb. Submitted by: jhb Reviewed by: jhb (man page) Approved by: re (Ken Smith) MFC after: 1 week

|
|
If the

.Ar port
|
|
and
|
|
.Ar spacing
|
|
are not specified the interface type default will be used. Only specify

either the
|
|
.Ar port
|
|
for I/O access or
|
|
.Ar maddr
|
|
for memory access.
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Tn IPMI
|
|
(Intelligent Platform Management Interface) is a standard for
|
|
monitoring system hardware by permitting generic code to detect
|
|
and monitor the sensors in a system.
|
|
The
|
|
.Tn IPMI
|
|
standard offers watchdog support, an FRU database, and other
|
|
support extensions.
|
|
It is currently being adopted by the makers of many
|
|
single board and embedded system manufacturers.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver in
|
|
.Fx
|
|
is heavily adopted from the standard and
|
|
.Tn Linux
|
|
driver; however, not all features described in the
|
|
standard are supported.
|
|
.Sh IOCTLS
|
|
Sending and receiving messages through the
|
|
.Nm
|
|
driver requires the use of
|
|
.Xr ioctl 2 .
|
|
The ioctls are used due to the complexity of
|
|
data sent to and from the device.
|
|
The
|
|
.Xr ioctl 2
|
|
command codes below are defined in
|
|
.In sys/ipmi.h .
|
|
The third argument to
|
|
.Xr ioctl 2
|
|
should be a pointer to the type indicated.
|
|
.Pp
|
|
Currently the following ioctls are supported:
|
|
.Bl -tag -width indent
|
|
.It Dv IPMICTL_RECEIVE_MSG Pq Vt "struct ipmi_recv"
|
|
Receive a message.
|
|
Possible error values:
|
|
.Bl -tag -width Er
|
|
.It Bq Er EAGAIN
|
|
No messages are in the process queue.
|
|
.It Bq Er EFAULT
|
|
An address supplied was invalid.
|
|
.It Bq Er EMSGSIZE
|
|
The address could not fit in the message buffer and
|
|
will remain in the buffer.
|
|
.El
|
|
.It Dv IPMICTL_RECEIVE_MSG_TRUNC Pq Vt "struct ipmi_recv"
|
|
Like
|
|
.Dv IPMICTL_RECEIVE_MSG
|
|
but if the message cannot fit into the buffer, it
|
|
will truncate the contents instead of leaving the data
|
|
in the buffer.
|
|
.It Dv IPMICTL_SEND_COMMAND Pq Vt "struct ipmi_req"
|
|
Send a message to the interface.
|
|
Possible error values:
|
|
.Bl -tag -width Er
|
|
.It Bq Er EFAULT
|
|
An address supplied was invalid
|
|
.It Bq Er ENOMEM
|
|
Buffers could not be allowed for the command, out of memory.
|
|
.El
|
|
.It Dv IPMICTL_SET_MY_ADDRESS_CMD Pq Vt "unsigned int"
|
|
Set the slave address for source messages.
|
|
.It Dv IPMICTL_GET_MY_ADDRESS_CMD Pq Vt "unsigned int"
|
|
Get the slave address for source messages.
|
|
.It Dv IPMICTL_SET_MY_LUN_CMD Pq Vt "unsigned int"
|
|
Set the slave LUN for source messages.
|
|
.It Dv IPMICTL_GET_MY_LUN_CMD Pq Vt "unsigned int"
|
|
Get the slave LUN for source messages.
|
|
.El
|
|
.Ss Unimplemented Ioctls
|
|
.Bl -tag -width indent
|
|
.It Dv IPMICTL_REGISTER_FOR_CMD Pq Vt "struct ipmi_cmdspec"
|
|
Register to receive a specific command
|
|
Possible error values:
|
|
.Bl -tag -width Er
|
|
.It Bq Er EFAULT
|
|
An supplied address was invalid.
|
|
.It Bq Er EBUSY
|
|
The network function/command is already in use.
|
|
.It Bq Er ENOMEM
|
|
Could not allocate memory.
|
|
.El
|
|
.It Dv IPMICTL_UNREGISTER_FOR_CMD Pq Vt "struct ipmi_cmdspec"
|
|
Unregister to receive a specific command
|
|
Possible error values:

|
.Bl -tag -width Er
|
|
.It Bq Er EFAULT
|
|
An address supplied was invalid.
|
|
.It Bq Er ENOENT
