e6bd5983ca Add CAM infrastructure to allow reporting when a drive's long read capacity
data changes.

cam_ccb.h:	Add a new advanced information type, CDAI_TYPE_RCAPLONG,
		for long read capacity data.

cam_xpt_internal.h:
		Add a read capacity data pointer and length to struct cam_ed.

cam_xpt.c:	Free the read capacity buffer when a device goes away.
		While we're here, make sure we don't leak memory for other
		malloced fields in struct cam_ed.

scsi_all.c:	Update the scsi_read_capacity_16() to take a uint8_t * and
		a length instead of just a pointer to the parameter data
		structure.  This will hopefully make this function somewhat
		immune to future changes in the parameter data.

scsi_all.h:	Add some extra bit definitions to struct
		scsi_read_capacity_data_long, and bump up the structure
		size to the full size specified by SBC-3.

		Change the prototype for scsi_read_capacity_16().

scsi_da.c:	Register changes in read capacity data with the transport
		layer.  This allows the transport layer to send out an
		async notification to interested parties.  Update the
		dasetgeom() API.

		Use scsi_extract_sense_len() instead of
		scsi_extract_sense().

scsi_xpt.c:	Add support for the new CDAI_TYPE_RCAPLONG advanced
		information type.

		Make sure we set the physpath pointer to NULL after freeing
		it.  This allows blindly freeing it in the struct cam_ed
		destructor.

sys/param.h:	Bump __FreeBSD_version from 1000005 to 1000006 to make it
		easier for third party drivers to determine that the read
		capacity data async notification is available.

camcontrol.c,
mptutil/mpt_cam.c:
		Update these for the new scsi_read_capacity_16() argument
		structure.

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.

1cc052e80f Add descriptor sense support to CAM, and honor sense residuals properly in
CAM.

Desriptor sense is a new sense data format that originated in SPC-3.  Among
other things, it allows for an 8-byte info field, which is necessary to
pass back block numbers larger than 4 bytes.

This change adds a number of new functions to scsi_all.c (and therefore
libcam) that abstract out most access to sense data.

This includes a bump of CAM_VERSION, because the CCB ABI has changed.
Userland programs that use the CAM pass(4) driver will need to be
recompiled.

camcontrol.c:	Change uses of scsi_extract_sense() to use
		scsi_extract_sense_len().

		Use scsi_get_sks() instead of accessing sense key specific
		data directly.

scsi_modes:	Update the control mode page to the latest version (SPC-4).

scsi_cmds.c,
scsi_target.c:	Change references to struct scsi_sense_data to struct
		scsi_sense_data_fixed.  This should be changed to allow the
		user to specify fixed or descriptor sense, and then use
		scsi_set_sense_data() to build the sense data.

ps3cdrom.c:	Use scsi_set_sense_data() instead of setting sense data
		manually.

cam_periph.c:	Use scsi_extract_sense_len() instead of using
		scsi_extract_sense() or accessing sense data directly.

cam_ccb.h:	Bump the CAM_VERSION from 0x15 to 0x16.  The change of
		struct scsi_sense_data from 32 to 252 bytes changes the
		size of struct ccb_scsiio, but not the size of union ccb.
		So the version must be bumped to prevent structure
		mis-matches.

scsi_all.h:	Lots of updated SCSI sense data and other structures.

		Add function prototypes for the new sense data functions.

		Take out the inline implementation of scsi_extract_sense().
		It is now too large to put in a header file.

		Add macros to calculate whether fields are present and
		filled in fixed and descriptor sense data

scsi_all.c:	In scsi_op_desc(), allow the user to pass in NULL inquiry
		data, and we'll assume a direct access device in that case.

		Changed the SCSI RESERVED sense key name and description
		to COMPLETED, as it is now defined in the spec.

		Change the error recovery action for a number of read errors
		to prevent lots of retries when the drive has said that the
		block isn't accessible.  This speeds up reconstruction of
		the block by any RAID software running on top of the drive
		(e.g. ZFS).

		In scsi_sense_desc(), allow for invalid sense key numbers.
		This allows calling this routine without checking the input
		values first.

		Change scsi_error_action() to use scsi_extract_sense_len(),
		and handle things when invalid asc/ascq values are
		encountered.

		Add a new routine, scsi_desc_iterate(), that will call the
		supplied function for every descriptor in descriptor format
		sense data.

		Add scsi_set_sense_data(), and scsi_set_sense_data_va(),
		which build descriptor and fixed format sense data.  They
		currently default to fixed format sense data.

		Add a number of scsi_get_*() functions, which get different
		types of sense data fields from either fixed or descriptor
		format sense data, if the data is present.

		Add a number of scsi_*_sbuf() functions, which print
		formatted versions of various sense data fields.  These
		functions work for either fixed or descriptor sense.

		Add a number of scsi_sense_*_sbuf() functions, which have a
		standard calling interface and print the indicated field.
		These functions take descriptors only.

		Add scsi_sense_desc_sbuf(), which will print a formatted
		version of the given sense descriptor.

		Pull out a majority of the scsi_sense_sbuf() function and
		put it into scsi_sense_only_sbuf().  This allows callers
		that don't use struct ccb_scsiio to easily utilize the
		printing routines.  Revamp that function to handle
		descriptor sense and use the new sense fetching and
		printing routines.

		Move scsi_extract_sense() into scsi_all.c, and implement it
		in terms of the new function, scsi_extract_sense_len().
		The _len() version takes a length (which should be the
		sense length - residual) and can indicate which fields are
		present and valid in the sense data.

		Add a couple of new scsi_get_*() routines to get the sense
		key, asc, and ascq only.

mly.c:		Rename struct scsi_sense_data to struct
		scsi_sense_data_fixed.

sbp_targ.c:	Use the new sense fetching routines to get sense data
		instead of accessing it directly.

sbp.c:		Change the firewire/SCSI sense data transformation code to
		use struct scsi_sense_data_fixed instead of struct
		scsi_sense_data.  This should be changed later to use
		scsi_set_sense_data().

ciss.c:		Calculate the sense residual properly.  Use
		scsi_get_sense_key() to fetch the sense key.

mps_sas.c,
mpt_cam.c:	Set the sense residual properly.

iir.c:		Use scsi_set_sense_data() instead of building sense data by
		hand.

iscsi_subr.c:	Use scsi_extract_sense_len() instead of grabbing sense data
		directly.

umass.c:	Use scsi_set_sense_data() to build sense data.

		Grab the sense key using scsi_get_sense_key().

		Calculate the sense residual properly.

isp_freebsd.h:	Use scsi_get_*() routines to grab asc, ascq, and sense key
		values.

		Calculate and set the sense residual.

3501942bbe Lay groundwork in CAM for recording and reporting physical path and
other device attributes stored in the CAM Existing Device Table (EDT).
This includes some infrastructure requried by the enclosure services
driver to export physical path information.

Make the CAM device advanced info interface accept store requests.

  sys/cam/scsi/scsi_all.c:
  sys/cam/scsi/scsi_all.h:
	- Replace scsi_get_sas_addr() with a scsi_get_devid() which takes
	  a callback that decides whether to accept a particular descriptor.
	  Provide callbacks for NAA IEEE Registered addresses and for SAS
	  addresses, replacing the old function.  This is needed because
	  the old function doesn't work for an enclosure address for a SAS
	  device, which is not flagged as a SAS address, but is NAA IEEE
	  Registered.  It may be worthwhile merging this interface with the
	  devid match interface.
	- Add a few more defines for some device ID fields.

  sbin/camcontrol/camcontrol.c:
	- Update for the CCB_DEV_ADVINFO interface change.

  cam/cam_xpt_internal.h:
	- Add the new fields for the physical path string to the CAM EDT.
  cam/cam_ccb.h:
	- Rename CCB_GDEV_ADVINFO to simply CCB_DEV_ADVINFO, and the ccb
	  structure to ccb_dev_advinfo.
	- Add a flag that changes this CCB's action to store, rather than
	  the default, retrieve.
	- Add a new buffer type, CDAI_TYPE_PHYS_PATH, for the new CAM EDT
	  physpath field.
	- Remove the never-implemented transport & proto flags.
  cam/cam_xpt.c:
  cam/cam_xpt.h:
	- Add xpt_getattr(), which provides a wrapper for fetching a device's
	  attribute using the GEOM strings as key.  This method currently
	  supports "GEOM::ident" and "GEOM::physpath".

Extend the XPT_DEV_MATCH api to allow a device search by device ID.
As far as the API is concerned, device ID is a binary blob to be
interpreted by the transport layer.  The SCSI implementation assumes
it is an array of VPD device ID descriptors.

  sys/cam/cam_ccb.h:
	Create a new structure, device_id_match_pattern, and
	update the XPT_DEV_MATCH datastructures and flags so
	that this pattern type can be used.

  sys/cam/cam_xpt.c:
	- A single pattern matching on both inquiry data and device
	  ID is invalid.  Report any violators.
	- Pass device ID match requests through to the new routine
	  scsi_devid_match().  The direct call of a SCSI routine is
	  a layering violation, but no worse than the one a few
	  lines up that checks inquiry data.  Defer cleaning this
	  up until our future, larger, rototilling of CAM.
	- Zero out cam_ed and cam_et nodes on allocation.  Prior to
	  this change, device_id_len and device_id were not inialized,
	  preventing proper detection of the presence of this
	  information.

  sys/cam/scsi/scsi_all.c:
  sys/cam/scsi/scsi_all.h:
	Add the scsi_match_devid() routine.

Add a helper function for extracting peripherial driver names

  sys/cam/cam_periph.c:
  sys/cam/cam_periph.h:
	Add the cam_periph_list() method which fills an sbuf
	with a comma delimited list of the peripheral instances
	associated with a given CAM path.

Add a helper functions for SCSI commands used by the SES driver.

  sys/cam/scsi/scsi_all.c:
  sys/cam/scsi/scsi_all.h:
	Add structure definitions and csio filling functions for
	the receive diagnostic results and send diagnostic commands.

Misc CAM XPT cleanups.

  sys/cam/cam_xpt.c:
	Broadcast AC_FOUND_DEVICE and AC_PATH_REGISTERED
	events at the time async event handlers are attached
	even when registering just for events on a partitular
	SIM.  Previously, you had to register for these
	events on all SIMs in the system in order to get
	the initial broadcast even though subsequent device
	and path arrivals would be delivered.

  sys/cam/cam_xpt.c:
	Remove SIM mutex held asserts from path accessors.
	CAM paths are reference counted and it is this
	reference count, not the sim mutex, that garantees
	they are stable.

7c103dde1e Fix a few issues related to the XPT_GDEV_ADVINFO CCB.
camcontrol.c:	In buildbusdevlist(), don't attempt to get call
		getdevid() for an unconfigured device, even when the
		verbose flag is set.  The cam_open_btl() call will almost
		certainly fail.

		Probe for the buffer size when issuing the XPT_GDEV_ADVINFO
		CCB.  Probing for the buffer size first helps us avoid
		allocating the maximum buffer size when it really may not
		be necessary.  This also helps avoid errors from
		cam_periph_mapmem() if we attempt to map more than MAXPHYS.

cam_periph.c:	In cam_periph_mapmem(), if the XPT_GDEV_ADVINFO CCB
		shows a bufsiz of 0, we don't have anything to map,
		so just return.

		Also, set the maximum mapping size to MAXPHYS
		instead of DFLTPHYS for XPT_GDEV_ADVINFO CCBs,
		since they don't actually go down to the hardware.

scsi_pass.c:	Don't bother mapping the buffer in XPT_GDEV_ADVINFO
		CCBs if bufsiz is 0.

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.

SATA revision negotiation for both SATA and PATA SIMs.
- Make ahci(4) and siis(4) to use submitted maximum tag number, when
scheduling requests. It allows to support NCQ on devices with lower tags
count then controller supports.
- Make PMP driver to report attached devices connection speeds.
- Implement ATA mode negotiation between user settings, device and
controller capabilities.

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.

f553b7b391 Add SCSI READ CAPACITY support to camcontrol. The new 'readcap' subcommand
will automatically issue the 16 byte verison of read capacity if the device
in question is larger than 2TB.

There are also a number of output options here (last block, number of
blocks, human readable) that should meet most needs, and also aid in
scripting.

3623222e67 It's confusing to say that "Command Queueing Supported" just based
upon the scsi flag validity field. Instead, just say "Command Queueing Enabled"
when it is- otherwise remain mute.
