Add Serial Management Protocol (SMP) passthrough support to CAM.

Browse Source 
This includes support in the kernel, camcontrol(8), libcam and the mps(4)
driver for SMP passthrough.

The CAM SCSI probe code has been modified to fetch Inquiry VPD page 0x00
to determine supported pages, and will now fetch page 0x83 in addition to
page 0x80 if supported.

Add two new CAM CCBs, XPT_SMP_IO, and XPT_GDEV_ADVINFO.  The SMP CCB is
intended for SMP requests and responses.  The ADVINFO is currently used to
fetch cached VPD page 0x83 data from the transport layer, but is intended
to be extensible to fetch other types of device-specific data.

SMP-only devices are not currently represented in the CAM topology, and so
the current semantics are that the SIM will route SMP CCBs to either the
addressed device, if it contains an SMP target, or its parent, if it
contains an SMP target.  (This is noted in cam_ccb.h, since it will change
later once we have the ability to have SMP-only devices in CAM's topology.)

smp_all.c,
smp_all.h:		New helper routines for SMP.  This includes
			SMP request building routines, response parsing
			routines, error decoding routines, and structure
			definitions for a number of SMP commands.

libcam/Makefile:	Add smp_all.c to libcam, so that SMP functionality
			is available to userland applications.

camcontrol.8,
camcontrol.c:		Add smp passthrough support to camcontrol.  Several
			new subcommands are now available:

			'smpcmd' functions much like 'cmd', except that it
			allows the user to send generic SMP commands.

			'smprg' sends the SMP report general command, and
			displays the decoded output.  It will automatically
			fetch extended output if it is available.

			'smppc' sends the SMP phy control command, with any
			number of potential options.  Among other things,
			this allows the user to reset a phy on a SAS
			expander, or disable a phy on an expander.

			'smpmaninfo' sends the SMP report manufacturer
			information and displays the decoded output.

			'smpphylist' displays a list of phys on an
			expander, and the CAM devices attached to those
			phys, if any.

cam.h,
cam.c:			Add a status value for SMP errors
			(CAM_SMP_STATUS_ERROR).

			Add a missing description for CAM_SCSI_IT_NEXUS_LOST.

			Add support for SMP commands to cam_error_string().

cam_ccb.h:		Rename the CAM_DIR_RESV flag to CAM_DIR_BOTH.  SMP
			commands are by nature bi-directional, and we may
			need to support bi-directional SCSI commands later.

			Add the XPT_SMP_IO CCB.  Since SMP commands are
			bi-directional, there are pointers for both the
			request and response.

			Add a fill routine for SMP CCBs.

			Add the XPT_GDEV_ADVINFO CCB.  This is currently
			used to fetch cached page 0x83 data from the
			transport later, but is extensible to fetch many
			other types of data.

cam_periph.c:		Add support in cam_periph_mapmem() for XPT_SMP_IO
			and XPT_GDEV_ADVINFO CCBs.

cam_xpt.c:		Add support for executing XPT_SMP_IO CCBs.

cam_xpt_internal.h:	Add fields for VPD pages 0x00 and 0x83 in struct
			cam_ed.

scsi_all.c:		Add scsi_get_sas_addr(), a function that parses
			VPD page 0x83 data and pulls out a SAS address.

scsi_all.h:		Add VPD page 0x00 and 0x83 structures, and a
			prototype for scsi_get_sas_addr().

scsi_pass.c:		Add support for mapping buffers in XPT_SMP_IO and
			XPT_GDEV_ADVINFO CCBs.

scsi_xpt.c:		In the SCSI probe code, first ask the device for
			VPD page 0x00.  If any VPD pages are supported,
			that page is required to be implemented.  Based on
			the response, we may probe for the serial number
			(page 0x80) or device id (page 0x83).

			Add support for the XPT_GDEV_ADVINFO CCB.

sys/conf/files:		Add smp_all.c.

mps.c:			Add support for passing in a uio in mps_map_command(),
			so we can map a S/G list at once.

			Add support for SMP passthrough commands in
			mps_data_cb().  SMP is a special case, because the
			first buffer in the S/G list is outbound and the
			second buffer is inbound.

			Add support for warning the user if the busdma code
			comes back with more buffers than will work for the
			command.  This will, for example, help the user
			determine why an SMP command failed if busdma comes
			back with three buffers.

mps_pci.c:		Add sys/uio.h.

mps_sas.c:		Add the SAS address and the parent handle to the
			list of fields we pull from device page 0 and cache
			in struct mpssas_target.  These are needed for SMP
			passthrough.

			Add support for the XPT_SMP_IO CCB.  For now, this
			CCB is routed to the addressed device if it supports
			SMP, or to its parent if it does not and the parent
			does.  This is necessary because CAM does not
			currently support SMP-only nodes in the topology.

			Make SMP passthrough support conditional on
			__FreeBSD_version >= 900026.  This will make it
			easier to MFC this change to the driver without
			MFCing the CAM changes as well.

mps_user.c:		Un-staticize mpi_init_sge() so we can use it for
			the SMP passthrough code.

mpsvar.h:		Add a uio and iovecs into struct mps_command for
			SMP passthrough commands.

			Add a cm_max_segs field to struct mps_command so
			that we can warn the user if busdma comes back with
			too many segments.

			Clear the cm_reply when a command gets freed.  If
			it is not cleared, reply frames will eventually get
			freed into the pool multiple times and corrupt the
			pool.  (This fix is from scottl.)

			Add a prototype for mpi_init_sge().

sys/param.h:		Bump __FreeBSD_version to 900026 for the for the
			inclusion of the XPT_GDEV_ADVINFO and XPT_SMP_IO
			CAM CCBs.

.Sq - ,
11 result registers will be written to standard output in hex.
.El
.It Ic smpcmd
Allows the user to send an arbitrary Serial
Management Protocol (SMP) command to a device.
The
.Ic smpcmd
function requires the
.Fl r
argument to specify the SMP request to be sent, and the
.Fl R
argument to specify the format of the SMP response.
The syntax for the SMP request and response arguments is documented in
.Xr cam_cdbparse 3 .
.Pp
Note that SAS adapters that support SMP passthrough (at least the currently
known adapters) do not accept CRC bytes from the user in the request and do
not pass CRC bytes back to the user in the response.
Therefore users should not include the CRC bytes in the length of the
request and not expect CRC bytes to be returned in the response.
.Bl -tag -width 17n
.It Fl r Ar len Ar fmt Op args
This specifies the size of the SMP request, without the CRC bytes, and the
SMP request format. If the format is
.Sq - ,
.Ar len
bytes of data will be read from standard input and written as the SMP
request.
.It Fl R Ar len Ar fmt Op args
This specifies the size of the buffer allocated for the SMP response, and
the SMP response format.
If the format is
.Sq - ,
.Ar len
bytes of data will be allocated for the response and the response will be
written to standard output.
.El
.It Ic smprg
Allows the user to send the Serial Management Protocol (SMP) Report General
command to a device.
.Nm
will display the data returned by the Report General command.
If the SMP target supports the long response format, the additional data
will be requested and displayed automatically.
.Bl -tag -width 8n
.It Fl l
Request the long response format only.
Not all SMP targets support the long response format.
This option causes
.Nm
to skip sending the initial report general request without the long bit set
and only issue a report general request with the long bit set.
.El
.It Ic smppc
Allows the user to issue the Serial Management Protocol (SMP) PHY Control
command to a device.
This function should be used with some caution, as it can render devices
inaccessible, and could potentially cause data corruption as well.
The
.Fl p
argument is required to specify the PHY to operate on.
.Bl -tag -width 17n
.It Fl p Ar phy
Specify the PHY to operate on.
This argument is required.
.It Fl l
Request the long request/response format.
Not all SMP targets support the long response format.
For the PHY Control command, this currently only affects whether the
request length is set to a value other than 0.
.It Fl o Ar operation
Specify a PHY control operation.
Only one
.Fl o
operation may be specified.
The operation may be specified numerically (in decimal, hexadecimal, or octal)
or one of the following operation names may be specified:
.Bl -tag -width 16n
.It nop
No operation.
It is not necessary to specify this argument.
.It linkreset
Send the LINK RESET command to the phy.
.It hardreset
Send the HARD RESET command to the phy.
.It disable
Send the DISABLE command to the phy.
Note that the LINK RESET or HARD RESET commands should re-enable the phy.
.It clearerrorlog
Send the CLEAR ERROR LOG command.
This clears the error log counters for the specified phy.
.It clearaffiliation
Send the CLEAR AFFILIATION command.
This clears the affiliation from the STP initiator port with the same SAS
address as the SMP initiator that requests the clear operation.
.It sataportsel
Send the TRANSMIT SATA PORT SELECTION SIGNAL command to the phy.
This will cause a SATA port selector to use the given phy as its active phy
and make the other phy inactive.
.It clearitnl
Send the CLEAR STP I_T NEXUS LOSS command to the PHY.
.It setdevname
Send the SET ATTACHED DEVICE NAME command to the PHY.
This requires the
.Fl d
argument to specify the device name.
.El
.It Fl d Ar name
Specify the attached device name.
This option is needed with the
.Fl o Ar setdevname
phy operation.
The name is a 64-bit number, and can be specified in decimal, hexadecimal
or octal format.
.It Fl m Ar rate
Set the minimum physical link rate for the phy.
This is a numeric argument.
Currently known link rates are:
.Bl -tag -width 5n
.It 0x0
Do not change current value.
.It 0x8
1.5 Gbps
.It 0x9
3 Gbps
.It 0xa
6 Gbps
.El
.Pp
Other values may be specified for newer physical link rates.
.It Fl M Ar rate
Set the maximum physical link rate for the phy.
This is a numeric argument.
See the
.Fl m
argument description for known link rate arguments.
.It Fl T Ar pp_timeout
Set the partial pathway timeout value, in microseconds.
See the
.Tn ANSI
.Tn SAS
Protcol Layer (SPL)
specification for more information on this field.
.It Fl a Ar enable|disable
Enable or disable SATA slumber phy power conditions.
.It Fl A Ar enable|disable
Enable or disable SATA partial power conditions.
.It Fl s Ar enable|disable
Enable or disable SAS slumber phy power conditions.
.It Fl S Ar enable|disable
Enable or disable SAS partial phy power conditions.
.El
.It Ic smpphylist
List phys attached to a SAS expander, the address of the end device
attached to the phy, and the inquiry data for that device and peripheral
devices attached to that device.
The inquiry data and peripheral devices are displayed if available.
.Bl -tag -width 5n
.It Fl l
Turn on the long response format for the underlying SMP commands used for
this command.
