7027b9cda4 Change 'camcontrol defects' to first probe a drive to find out how much
defect information it has before grabbing the full defect list.

This works around a bug with some Hitachi drives that generate data overrun
errors when they are asked for more defect data than they have.

The change is done in a spec-compliant way, so it should have no negative
impact on drives that don't have this issue.

This is based on work originally done at Sandvine.

scsi_da.h:	Add a define for the maximum amount of data that can be
		contained in a defect list.

camcontrol.c:	Update the readdefects() function to issue an initial
		command to determine the length of the defect list, and
		then use that length in the request for the full defect
		list.

camcontrol.8:	Add a note that some drives will report 0 defects available
		if you don't request either the PLIST or GLIST.

1f4782a4c1 Add firmware update support for SCSI devices.
Firmware can be reprogrammed on devices from Hitachi, HP, IBM, Plextor,
Quantum, and Seagate.  At least one device from each manufacturer has
been tested with some version of this code, and it has been used to
update thousands of drives so far.

The man page suggests having a backup of the drive's data, and the
operation must be confirmed, either interactively or on the command
line.  (This is the same as the confirmation on the format command.)

This work is largely derived from fwprog.c by Andre Albsmeier.

06e794928b Add Serial Management Protocol (SMP) passthrough support to CAM.
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.

52c9ce25d8 Separate the parallel scsi knowledge out of the core of the XPT, and
modularize it so that new transports can be created.

Add a transport for SATA

Add a periph+protocol layer for ATA

Add a driver for AHCI-compliant hardware.

Add a maxio field to CAM so that drivers can advertise their max
I/O capability.  Modify various drivers so that they are insulated
from the value of MAXPHYS.

The new ATA/SATA code supports AHCI-compliant hardware, and will override
the classic ATA driver if it is loaded as a module at boot time or compiled
into the kernel.  The stack now support NCQ (tagged queueing) for increased
performance on modern SATA drives.  It also supports port multipliers.

ATA drives are accessed via 'ada' device nodes.  ATAPI drives are
accessed via 'cd' device nodes.  They can all be enumerated and manipulated
via camcontrol, just like SCSI drives.  SCSI commands are not translated to
their ATA equivalents; ATA native commands are used throughout the entire
stack, including camcontrol.  See the camcontrol manpage for further
details.  Testing this code may require that you update your fstab, and
possibly modify your BIOS to enable AHCI functionality, if available.

This code is very experimental at the moment.  The userland ABI/API has
changed, so applications will need to be recompiled.  It may change
further in the near future.  The 'ada' device name may also change as
more infrastructure is completed in this project.  The goal is to
eventually put all CAM busses and devices until newbus, allowing for
interesting topology and management options.

Few functional changes will be seen with existing SCSI/SAS/FC drivers,
though the userland ABI has still changed.  In the future, transports
specific modules for SAS and FC may appear in order to better support
the topologies and capabilities of these technologies.

The modularization of CAM and the addition of the ATA/SATA modules is
meant to break CAM out of the mold of being specific to SCSI, letting it
grow to be a framework for arbitrary transports and protocols.  It also
allows drivers to be written to support discrete hardware without
jeopardizing the stability of non-related hardware.  While only an AHCI
driver is provided now, a Silicon Image driver is also in the works.
Drivers for ICH1-4, ICH5-6, PIIX, classic IDE, and any other hardware
is possible and encouraged.  Help with new transports is also encouraged.

42cb6a80b6 Implement 'camcontrol reportluns'. This allows users to send the SCSI

camcontrol.[c8]:	Implement reportluns.  This tries to print the LUNs
			out in a reasonable format.  Only the periph
			addressing method has been tested, since very little
			hardware that I know of supports the other methods.

scsi_all.[ch]:		Revamp the report luns CDB structure and helper
			functions.  This constitutes a little bit of an API
			change, but since the old CDB length was 10 bytes,
			and the REPORT LUNS CDB length is actually 12 bytes,
			it's clear that no one was using this API in the

5710d224b6 Add 'camcontrol rescan all' and 'camcontrol reset all' functionality to
camcontrol.

This enables rescanning all busses or resetting all busses in a system.
The current implementation is not the ideal way to do it -- the ideal way
to do it would be for the transport layer to handle wildcarded busses on
bus rescan and reset operations.  The current implementation enumerates all
the busses and sends a rescan or reset CCB individually.  Handling this
behavior in the transport layer will happen later.

7e32b20d95 This is an overhaul of the mode page handling in camcontrol as well as
related patches. These include:
	* Mode page editting can be scripted. This involves two
	  things: first, if stdin is not a tty, changes are read from
	  stdin rather than invoking $EDITOR. Second, and more
	  importantly, not all modepage entries must be included in the
	  change set. This means that camcontrol can now gracefully handle
	  more intrusive editting from the $EDITOR, including removal or
	  rearrangement of lines. It also means that you can do stuff
	  like:
		# echo "WCE: 1" | camcontrol modepage da3 -m 8 -e
		# newfs /dev/da3
		# echo "WCE: 0" | camcontrol modepage da3 -m 8 -e
	* Range-checking on user-supplied input values. modeedit.c now
	  uses the field width specifiers to determine the maximum
	  allowable value for a field. If the user enters a value larger
	  than the maximum, it clips the value to the max and warns the
	  user. This also involved patching cam_cmdparse.c to be more
	  consistent with regards to the "count" parameter to arg_put
	  (previously is was the length of strings and 1 for all integral
	  types). The cam_cdbparse(3) man page was also updated to reflect
	  the revised semantics.
	* In the process, I removed the 64 entry limit on mode pages (not
	  that we were even close to hitting that limit). This was a nice
	  side-effect of the other changes.
	* Technically, the new mode editting functionality allows editting
	  of character array entries in mode pages (type 'c' or 'z'),
	  however since buff_encode doesn't grok them it is currently
	  useless.
	* Camcontrol gained two new options related to mode pages: -l and
	  -b. The former lists all available mode pages for a given
	  device. The latter forces mode page display in binary format
	  (the default when no mode page definition was found in
	  scsi_modes).
	* Added support for mode page names to scsi_modes. Allows names to
	  be displayed alongside mode numbers in the mode page
	  listing. Updated scsi_modes to use the new functionality. This
	  also adds the semicolon into the scsi_modes syntax as an
	  optional mode page definition terminator. This is needed to name
	  pages without providing a page format definition.
	* Updated scsi_all.h to include a structure describing mode page
	  headers.
	* Added $FreeBSD$ line to scsi_modes.
