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.

Improve camcontrol(8) handling of drive defect data.
This includes a new summary mode (-s) for camcontrol defects that
quickly tells the user the most important thing: how many defects
are in the requested list. The actual location of the defects is
less important.
Modern drives frequently have more than the 8191 defects that can
be reported by the READ DEFECT DATA (10) command. If they don't
have that many grown defects, they certainly have more than 8191
defects in the primary (i.e. factory) defect list.
The READ DEFECT DATA (12) command allows for longer parameter
lists, as well as indexing into the list of defects, and so allows
reporting many more defects.
This has been tested with HGST drives and Seagate drives, but
does not fully work with Seagate drives. Once I have a Seagate
spec I may be able to determine whether it is possible to make it
work with Seagate drives.
scsi_da.h: Add a definition for the new long block defect
format.
Add bit and mask definitions for the new extended
physical sector and bytes from index defect
formats.
Add a prototype for the new scsi_read_defects() CDB
building function.
scsi_da.c: Add a new scsi_read_defects() CDB building function.
camcontrol(8) was previously composing CDBs manually.
This is long overdue.
camcontrol.c: Revamp the camcontrol defects subcommand. We now
go through multiple stages in trying to get defect
data off the drive while avoiding various drive
firmware quirks.
We start off by requesting the defect header with
the 10 byte command. If we're in summary mode (-s)
and the drive reports fewer defects than can be
represented in the 10 byte header, we're done.
Otherwise, we know that we need to issue the
12 byte command if the drive reports the maximum
number of defects.
If we're in summary mode, we're done if we get a
good response back when asking for the 12 byte header.
If the user has asked for the full list, then we
use the address descriptor index field in the 12
byte CDB to step through the list in 64K chunks.
64K is small enough to work with most any ancient
or modern SCSI controller.
Add support for printing the new long block defect
format, as well as the extended physical sector and
bytes from index formats. I don't have any drives
that support the new formats.
Add a hexadecimal output format that can be turned
on with -X.
Add a quiet mode (-q) that can be turned on with
the summary mode (-s) to just print out a number.
Revamp the error detection and recovery code for
the defects command to work with HGST drives.
Call the new scsi_read_defects() CDB building
function instead of rolling the CDB ourselves.
Pay attention to the residual from the defect list
request when printing it out, so we don't run off
the end of the list.
Use the new scsi_nv library routines to convert
from strings to numbers and back.
camcontrol.8: Document the new defect formats (longblock, extbfi,
extphys) and command line options (-q, -s, -S and
-X) for the defects subcommand.
Explain a little more about what drives generally
do and don't support.

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.

Add a number of interrelated CAM feature enhancements and bug fixes.
NOTE: These changes will require recompilation of any userland
applications, like cdrecord, xmcd, etc., that use the CAM passthrough
interface. A make world is recommended.
camcontrol.[c8]:
- We now support two new commands, "tags" and "negotiate".
- The tags commands allows users to view the number of tagged
openings for a device as well as a number of other related
parameters, and it allows users to set tagged openings for
a device.
- The negotiate command allows users to enable and disable
disconnection and tagged queueing, set sync rates, offsets
and bus width. Note that not all of those features are
available for all controllers. Only the adv, ahc, and ncr
drivers fully support all of the features at this point.
Some cards do not allow the setting of sync rates, offsets and
the like, and some of the drivers don't have any facilities to
do so. Some drivers, like the adw driver, only support enabling
or disabling sync negotiation, but do not support setting sync
rates.
- new description in the camcontrol man page of how to format a disk
- cleanup of the camcontrol inquiry command
- add support in the 'devlist' command for skipping unconfigured devices if
-v was not specified on the command line.
- make use of the new base_transfer_speed in the path inquiry CCB.
- fix CCB bzero cases
cam_xpt.c, cam_sim.[ch], cam_ccb.h:
- new flags on many CCB function codes to designate whether they're
non-immediate, use a user-supplied CCB, and can only be passed from
userland programs via the xpt device. Use these flags in the transport
layer and pass driver to categorize CCBs.
- new flag in the transport layer device matching code for device nodes
that indicates whether a device is unconfigured
- bump the CAM version from 0x10 to 0x11
- Change the CAM ioctls to use the version as their group code, so we can
force users to recompile code even when the CCB size doesn't change.
- add + fill in a new value in the path inquiry CCB, base_transfer_speed.
Remove a corresponding field from the cam_sim structure, and add code to
every SIM to set this field to the proper value.
- Fix the set transfer settings code in the transport layer.
scsi_cd.c:
- make some variables volatile instead of just casting them in various
places
- fix a race condition in the changer code
- attach unless we get a "logical unit not supported" error. This should
fix all of the cases where people have devices that return weird errors
when they don't have media in the drive.
scsi_da.c:
- attach unless we get a "logical unit not supported" error
scsi_pass.c:
- for immediate CCBs, just malloc a CCB to send the user request in. This
gets rid of the 'held' count problem in camcontrol tags.
scsi_pass.h:
- change the CAM ioctls to use the CAM version as their group code.
adv driver:
- Allow changing the sync rate and offset separately.
adw driver
- Allow changing the sync rate and offset separately.
aha driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
ahc driver:
- Allow setting offset and sync rate separately
bt driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
NCR driver:
- Fix the ultra/ultra 2 negotiation bug
- allow setting both the sync rate and offset separately
Other HBA drivers:
- Put code in to set the base_transfer_speed field for
XPT_GET_TRAN_SETTINGS CCBs.

Add persistent reservation support to camcontrol(8).
camcontrol(8) now supports a new 'persist' subcommand that allows users to
issue SCSI PERSISTENT RESERVE IN / OUT commands.
sbin/camcontrol/Makefile:
Add persist.c.
sbin/camcontrol/persist.c:
New persistent reservation support for camcontrol(8).
We have support for all known operation modes for PERSISTENT RESERVE
IN and PERSISTENT RESERVE OUT.
exceptions noted above.
sbin/camcontrol/camcontrol.8:
Document the new 'persist' subcommand.
In the section on the Transport ID (-I) option, explain what
Transport IDs for each protocol should look like. At some point
some of this information could probably get moved off in a
separate man page, either on Transport IDs alone or a man page
documenting the Transport ID parsing code.
Add a number of examples of persistent reservation commands.
Persistent Reservations are complex enough that the average user
probably won't be able to get the commands exactly right by just
reading the man page. These examples show a few basic and
advanced examples of how to use persistent reservations.
sbin/camcontrol/camcontrol.h:
Move the definition for camcontrol_optret here, so we can use it
for the persistent reservation code.
Add a definition for the new scsipersist() function.
sbin/camcontrol/camcontrol.c:
Add 'persist' to the list of subcommands.
Document 'persist' in the help text.
sys/cam/scsi/scsi_all.c:
Add the scsi_persistent_reserve_in() and
scsi_persistent_reserve_out() CCB building functions.
Add a new function, scsi_transportid_sbuf(). This takes a
SCSI Transport ID (documented in SPC-4), and prints it to
an sbuf(9). There are some transports (like ATA, USB, and
SSA) for which there is no transport defined. We need to
come up with a reasonable thing to do if we're presented
with a Transport ID that claims to be for one of those
protocols.
Add new routines scsi_get_nv() and scsi_nv_to_str().
These functions do a table lookup to go between a string and an
integer. There are lots of table lookups needed in the
persistent reservation code in camcontrol(8).
Add a new function, scsi_parse_transportid(), along with leaf node
functions to parse:
FC, 1394 and SAS (scsi_parse_transportid_64bit())
iSCSI (scsi_parse_transportid_iscsi())
SPI (scsi_parse_transportid_spi())
RDMA (scsi_parse_transportid_rdma())
PCIe (scsi_parse_transportid_sop())
Transport IDs. Given a string with the general form proto,id these
functions create a SCSI Transport ID structure.
sys/cam/scsi/scsi_all.h:
Update the various persistent reservation data structures to
SPC4r36l, but also rename some fields that were previously
obsolete with the proper names from older SCSI specs. This
allows using older, obsolete persistent reservation types when
desired.
Add function prototypes for the new persistent reservation CCB
building functions.
Add a data strucure for the READ FULL STATUS service action
of the PERSISTENT RESERVE IN command.
Add Transport ID structures for all protocols described in SPC-4.
Add a new series of SCSI_PROTO_XXX definitions, and
redefine other defines in terms of these new definitions.
Add a prototype for scsi_transportid_sbuf().
Change a couple of "obsolete" persistent reservation data
structure fields into something more meaningful, based on
what the field was called when it was defined in the spec.
(e.g. SPC, SPC-2, etc.)
Create a new define, SPRI_MAX_LEN, for the maximum allocation

Add a number of interrelated CAM feature enhancements and bug fixes.
NOTE: These changes will require recompilation of any userland
applications, like cdrecord, xmcd, etc., that use the CAM passthrough
interface. A make world is recommended.
camcontrol.[c8]:
- We now support two new commands, "tags" and "negotiate".
- The tags commands allows users to view the number of tagged
openings for a device as well as a number of other related
parameters, and it allows users to set tagged openings for
a device.
- The negotiate command allows users to enable and disable
disconnection and tagged queueing, set sync rates, offsets
and bus width. Note that not all of those features are
available for all controllers. Only the adv, ahc, and ncr
drivers fully support all of the features at this point.
Some cards do not allow the setting of sync rates, offsets and
the like, and some of the drivers don't have any facilities to
do so. Some drivers, like the adw driver, only support enabling
or disabling sync negotiation, but do not support setting sync
rates.
- new description in the camcontrol man page of how to format a disk
- cleanup of the camcontrol inquiry command
- add support in the 'devlist' command for skipping unconfigured devices if
-v was not specified on the command line.
- make use of the new base_transfer_speed in the path inquiry CCB.
- fix CCB bzero cases
cam_xpt.c, cam_sim.[ch], cam_ccb.h:
- new flags on many CCB function codes to designate whether they're
non-immediate, use a user-supplied CCB, and can only be passed from
userland programs via the xpt device. Use these flags in the transport
layer and pass driver to categorize CCBs.
- new flag in the transport layer device matching code for device nodes
that indicates whether a device is unconfigured
- bump the CAM version from 0x10 to 0x11
- Change the CAM ioctls to use the version as their group code, so we can
force users to recompile code even when the CCB size doesn't change.
- add + fill in a new value in the path inquiry CCB, base_transfer_speed.
Remove a corresponding field from the cam_sim structure, and add code to
every SIM to set this field to the proper value.
- Fix the set transfer settings code in the transport layer.
scsi_cd.c:
- make some variables volatile instead of just casting them in various
places
- fix a race condition in the changer code
- attach unless we get a "logical unit not supported" error. This should
fix all of the cases where people have devices that return weird errors
when they don't have media in the drive.
scsi_da.c:
- attach unless we get a "logical unit not supported" error
scsi_pass.c:
- for immediate CCBs, just malloc a CCB to send the user request in. This
gets rid of the 'held' count problem in camcontrol tags.
scsi_pass.h:
- change the CAM ioctls to use the CAM version as their group code.
adv driver:
- Allow changing the sync rate and offset separately.
adw driver
- Allow changing the sync rate and offset separately.
aha driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
ahc driver:
- Allow setting offset and sync rate separately
bt driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
NCR driver:
- Fix the ultra/ultra 2 negotiation bug
- allow setting both the sync rate and offset separately
Other HBA drivers:
- Put code in to set the base_transfer_speed field for
XPT_GET_TRAN_SETTINGS CCBs.

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.

Improve camcontrol(8) handling of drive defect data.
This includes a new summary mode (-s) for camcontrol defects that
quickly tells the user the most important thing: how many defects
are in the requested list. The actual location of the defects is
less important.
Modern drives frequently have more than the 8191 defects that can
be reported by the READ DEFECT DATA (10) command. If they don't
have that many grown defects, they certainly have more than 8191
defects in the primary (i.e. factory) defect list.
The READ DEFECT DATA (12) command allows for longer parameter
lists, as well as indexing into the list of defects, and so allows
reporting many more defects.
This has been tested with HGST drives and Seagate drives, but
does not fully work with Seagate drives. Once I have a Seagate
spec I may be able to determine whether it is possible to make it
work with Seagate drives.
scsi_da.h: Add a definition for the new long block defect
format.
Add bit and mask definitions for the new extended
physical sector and bytes from index defect
formats.
Add a prototype for the new scsi_read_defects() CDB
building function.
scsi_da.c: Add a new scsi_read_defects() CDB building function.
camcontrol(8) was previously composing CDBs manually.
This is long overdue.
camcontrol.c: Revamp the camcontrol defects subcommand. We now
go through multiple stages in trying to get defect
data off the drive while avoiding various drive
firmware quirks.
We start off by requesting the defect header with
the 10 byte command. If we're in summary mode (-s)
and the drive reports fewer defects than can be
represented in the 10 byte header, we're done.
Otherwise, we know that we need to issue the
12 byte command if the drive reports the maximum
number of defects.
If we're in summary mode, we're done if we get a
good response back when asking for the 12 byte header.
If the user has asked for the full list, then we
use the address descriptor index field in the 12
byte CDB to step through the list in 64K chunks.
64K is small enough to work with most any ancient
or modern SCSI controller.
Add support for printing the new long block defect
format, as well as the extended physical sector and
bytes from index formats. I don't have any drives
that support the new formats.
Add a hexadecimal output format that can be turned
on with -X.
Add a quiet mode (-q) that can be turned on with
the summary mode (-s) to just print out a number.
Revamp the error detection and recovery code for
the defects command to work with HGST drives.
Call the new scsi_read_defects() CDB building
function instead of rolling the CDB ourselves.
Pay attention to the residual from the defect list
request when printing it out, so we don't run off
the end of the list.
Use the new scsi_nv library routines to convert
from strings to numbers and back.
camcontrol.8: Document the new defect formats (longblock, extbfi,
extphys) and command line options (-q, -s, -S and
-X) for the defects subcommand.
Explain a little more about what drives generally
do and don't support.

Add a number of interrelated CAM feature enhancements and bug fixes.
NOTE: These changes will require recompilation of any userland
applications, like cdrecord, xmcd, etc., that use the CAM passthrough
interface. A make world is recommended.
camcontrol.[c8]:
- We now support two new commands, "tags" and "negotiate".
- The tags commands allows users to view the number of tagged
openings for a device as well as a number of other related
parameters, and it allows users to set tagged openings for
a device.
- The negotiate command allows users to enable and disable
disconnection and tagged queueing, set sync rates, offsets
and bus width. Note that not all of those features are
available for all controllers. Only the adv, ahc, and ncr
drivers fully support all of the features at this point.
Some cards do not allow the setting of sync rates, offsets and
the like, and some of the drivers don't have any facilities to
do so. Some drivers, like the adw driver, only support enabling
or disabling sync negotiation, but do not support setting sync
rates.
- new description in the camcontrol man page of how to format a disk
- cleanup of the camcontrol inquiry command
- add support in the 'devlist' command for skipping unconfigured devices if
-v was not specified on the command line.
- make use of the new base_transfer_speed in the path inquiry CCB.
- fix CCB bzero cases
cam_xpt.c, cam_sim.[ch], cam_ccb.h:
- new flags on many CCB function codes to designate whether they're
non-immediate, use a user-supplied CCB, and can only be passed from
userland programs via the xpt device. Use these flags in the transport
layer and pass driver to categorize CCBs.
- new flag in the transport layer device matching code for device nodes
that indicates whether a device is unconfigured
- bump the CAM version from 0x10 to 0x11
- Change the CAM ioctls to use the version as their group code, so we can
force users to recompile code even when the CCB size doesn't change.
- add + fill in a new value in the path inquiry CCB, base_transfer_speed.
Remove a corresponding field from the cam_sim structure, and add code to
every SIM to set this field to the proper value.
- Fix the set transfer settings code in the transport layer.
scsi_cd.c:
- make some variables volatile instead of just casting them in various
places
- fix a race condition in the changer code
- attach unless we get a "logical unit not supported" error. This should
fix all of the cases where people have devices that return weird errors
when they don't have media in the drive.
scsi_da.c:
- attach unless we get a "logical unit not supported" error
scsi_pass.c:
- for immediate CCBs, just malloc a CCB to send the user request in. This
gets rid of the 'held' count problem in camcontrol tags.
scsi_pass.h:
- change the CAM ioctls to use the CAM version as their group code.
adv driver:
- Allow changing the sync rate and offset separately.
adw driver
- Allow changing the sync rate and offset separately.
aha driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
ahc driver:
- Allow setting offset and sync rate separately
bt driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
NCR driver:
- Fix the ultra/ultra 2 negotiation bug
- allow setting both the sync rate and offset separately
Other HBA drivers:
- Put code in to set the base_transfer_speed field for
XPT_GET_TRAN_SETTINGS CCBs.

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.

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

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.

Protocol Layer (SPL)
|
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.

Add a number of interrelated CAM feature enhancements and bug fixes.
NOTE: These changes will require recompilation of any userland
applications, like cdrecord, xmcd, etc., that use the CAM passthrough
interface. A make world is recommended.
camcontrol.[c8]:
- We now support two new commands, "tags" and "negotiate".
- The tags commands allows users to view the number of tagged
openings for a device as well as a number of other related
parameters, and it allows users to set tagged openings for
a device.
- The negotiate command allows users to enable and disable
disconnection and tagged queueing, set sync rates, offsets
and bus width. Note that not all of those features are
available for all controllers. Only the adv, ahc, and ncr
drivers fully support all of the features at this point.
Some cards do not allow the setting of sync rates, offsets and
the like, and some of the drivers don't have any facilities to
do so. Some drivers, like the adw driver, only support enabling
or disabling sync negotiation, but do not support setting sync
rates.
- new description in the camcontrol man page of how to format a disk
- cleanup of the camcontrol inquiry command
- add support in the 'devlist' command for skipping unconfigured devices if
-v was not specified on the command line.
- make use of the new base_transfer_speed in the path inquiry CCB.
- fix CCB bzero cases
cam_xpt.c, cam_sim.[ch], cam_ccb.h:
- new flags on many CCB function codes to designate whether they're
non-immediate, use a user-supplied CCB, and can only be passed from
userland programs via the xpt device. Use these flags in the transport
layer and pass driver to categorize CCBs.
- new flag in the transport layer device matching code for device nodes
that indicates whether a device is unconfigured
- bump the CAM version from 0x10 to 0x11
- Change the CAM ioctls to use the version as their group code, so we can
force users to recompile code even when the CCB size doesn't change.
- add + fill in a new value in the path inquiry CCB, base_transfer_speed.
Remove a corresponding field from the cam_sim structure, and add code to
every SIM to set this field to the proper value.
- Fix the set transfer settings code in the transport layer.
scsi_cd.c:
- make some variables volatile instead of just casting them in various
places
- fix a race condition in the changer code
- attach unless we get a "logical unit not supported" error. This should
fix all of the cases where people have devices that return weird errors
when they don't have media in the drive.
scsi_da.c:
- attach unless we get a "logical unit not supported" error
scsi_pass.c:
- for immediate CCBs, just malloc a CCB to send the user request in. This
gets rid of the 'held' count problem in camcontrol tags.
scsi_pass.h:
- change the CAM ioctls to use the CAM version as their group code.
adv driver:
- Allow changing the sync rate and offset separately.
adw driver
- Allow changing the sync rate and offset separately.
aha driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
ahc driver:
- Allow setting offset and sync rate separately

NCR driver:

camcontrol.[c8]:
- We now support two new commands, "tags" and "negotiate".
- The tags commands allows users to view the number of tagged
openings for a device as well as a number of other related
parameters, and it allows users to set tagged openings for
a device.
- The negotiate command allows users to enable and disable
disconnection and tagged queueing, set sync rates, offsets
and bus width. Note that not all of those features are
available for all controllers. Only the adv, ahc, and ncr
drivers fully support all of the features at this point.
Some cards do not allow the setting of sync rates, offsets and
the like, and some of the drivers don't have any facilities to
do so. Some drivers, like the adw driver, only support enabling
or disabling sync negotiation, but do not support setting sync
rates.
- new description in the camcontrol man page of how to format a disk
- cleanup of the camcontrol inquiry command
- add support in the 'devlist' command for skipping unconfigured devices if
-v was not specified on the command line.
- make use of the new base_transfer_speed in the path inquiry CCB.
- fix CCB bzero cases
cam_xpt.c, cam_sim.[ch], cam_ccb.h:
- new flags on many CCB function codes to designate whether they're
non-immediate, use a user-supplied CCB, and can only be passed from
userland programs via the xpt device. Use these flags in the transport
layer and pass driver to categorize CCBs.
- new flag in the transport layer device matching code for device nodes
that indicates whether a device is unconfigured
- bump the CAM version from 0x10 to 0x11
- Change the CAM ioctls to use the version as their group code, so we can
force users to recompile code even when the CCB size doesn't change.
- add + fill in a new value in the path inquiry CCB, base_transfer_speed.
Remove a corresponding field from the cam_sim structure, and add code to
every SIM to set this field to the proper value.
- Fix the set transfer settings code in the transport layer.
scsi_cd.c:
- make some variables volatile instead of just casting them in various
places

- The negotiate command allows users to enable and disable
disconnection and tagged queueing, set sync rates, offsets
and bus width. Note that not all of those features are
available for all controllers. Only the adv, ahc, and ncr

Some cards do not allow the setting of sync rates, offsets and

cam_xpt.c, cam_sim.[ch], cam_ccb.h:
- new flags on many CCB function codes to designate whether they're
non-immediate, use a user-supplied CCB, and can only be passed from
userland programs via the xpt device. Use these flags in the transport
layer and pass driver to categorize CCBs.
- new flag in the transport layer device matching code for device nodes
that indicates whether a device is unconfigured
- bump the CAM version from 0x10 to 0x11
- Change the CAM ioctls to use the version as their group code, so we can
force users to recompile code even when the CCB size doesn't change.
- add + fill in a new value in the path inquiry CCB, base_transfer_speed.
Remove a corresponding field from the cam_sim structure, and add code to
every SIM to set this field to the proper value.
- Fix the set transfer settings code in the transport layer.
scsi_cd.c:
- make some variables volatile instead of just casting them in various
places
- fix a race condition in the changer code
- attach unless we get a "logical unit not supported" error. This should
fix all of the cases where people have devices that return weird errors
when they don't have media in the drive.

Add a number of interrelated CAM feature enhancements and bug fixes.
NOTE: These changes will require recompilation of any userland
applications, like cdrecord, xmcd, etc., that use the CAM passthrough
interface. A make world is recommended.
camcontrol.[c8]:
- We now support two new commands, "tags" and "negotiate".
- The tags commands allows users to view the number of tagged
openings for a device as well as a number of other related
parameters, and it allows users to set tagged openings for
a device.
- The negotiate command allows users to enable and disable
disconnection and tagged queueing, set sync rates, offsets
and bus width. Note that not all of those features are
available for all controllers. Only the adv, ahc, and ncr
drivers fully support all of the features at this point.
Some cards do not allow the setting of sync rates, offsets and
the like, and some of the drivers don't have any facilities to
do so. Some drivers, like the adw driver, only support enabling
or disabling sync negotiation, but do not support setting sync
rates.
- new description in the camcontrol man page of how to format a disk
- cleanup of the camcontrol inquiry command
- add support in the 'devlist' command for skipping unconfigured devices if
-v was not specified on the command line.
- make use of the new base_transfer_speed in the path inquiry CCB.
- fix CCB bzero cases
cam_xpt.c, cam_sim.[ch], cam_ccb.h:
- new flags on many CCB function codes to designate whether they're
non-immediate, use a user-supplied CCB, and can only be passed from
userland programs via the xpt device. Use these flags in the transport
layer and pass driver to categorize CCBs.
- new flag in the transport layer device matching code for device nodes
that indicates whether a device is unconfigured
- bump the CAM version from 0x10 to 0x11
- Change the CAM ioctls to use the version as their group code, so we can
force users to recompile code even when the CCB size doesn't change.
- add + fill in a new value in the path inquiry CCB, base_transfer_speed.
Remove a corresponding field from the cam_sim structure, and add code to
every SIM to set this field to the proper value.
- Fix the set transfer settings code in the transport layer.

places

- fix a race condition in the changer code
- attach unless we get a "logical unit not supported" error. This should
fix all of the cases where people have devices that return weird errors
when they don't have media in the drive.
scsi_da.c:
- attach unless we get a "logical unit not supported" error
scsi_pass.c:
- for immediate CCBs, just malloc a CCB to send the user request in. This
gets rid of the 'held' count problem in camcontrol tags.
scsi_pass.h:
- change the CAM ioctls to use the CAM version as their group code.
adv driver:
- Allow changing the sync rate and offset separately.
adw driver
- Allow changing the sync rate and offset separately.
aha driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
ahc driver:
- Allow setting offset and sync rate separately
bt driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
NCR driver:
- Fix the ultra/ultra 2 negotiation bug
- allow setting both the sync rate and offset separately
Other HBA drivers:
- Put code in to set the base_transfer_speed field for
XPT_GET_TRAN_SETTINGS CCBs.

Low level formatting a disk will destroy ALL data on the disk.
|
|
|
|
|
Use
|
|
|
|
|
extreme caution when issuing this command.
|
|
|
|
|
Many users low-level format
|
|
|
|
|
disks that do not really need to be low-level formatted.
|
|
|
|
|
There are
|
2000-05-21 23:57:52 +00:00
|
|
|
relatively few scenarios that call for low-level formatting a disk.
|
|
|
|
|
One reason for
|
|
|
|
|
low-level formatting a disk is to initialize the disk after changing
|
2004-07-02 21:45:06 +00:00
|
|
|
its physical sector size.
|
|
|
|
|
Another reason for low-level formatting a disk
|
2000-05-21 23:57:52 +00:00
|
|
|
is to revive the disk if you are getting "medium format corrupted" errors
|
|
|
|
|
from the disk in response to read and write requests.
|
|
|
|
|
.Pp
|
2004-07-02 21:45:06 +00:00
|
|
|
Some disks take longer than others to format.
|
|
|
|
|
Users should specify a
|
|
|
|
|
timeout long enough to allow the format to complete.
|
|
|
|
|
The default format
|
|
|
|
|
timeout is 3 hours, which should be long enough for most disks.
|
|
|
|
|
Some hard
|
2000-05-21 23:57:52 +00:00
|
|
|
disks will complete a format operation in a very short period of time
|
2004-07-02 21:45:06 +00:00
|
|
|
(on the order of 5 minutes or less).
|
|
|
|
|
This is often because the drive
|
2005-02-13 22:25:33 +00:00
|
|
|
does not really support the FORMAT UNIT command -- it just accepts the
|
2000-05-21 23:57:52 +00:00
|
|
|
command, waits a few minutes and then returns it.

Add persistent reservation support to camcontrol(8).
camcontrol(8) now supports a new 'persist' subcommand that allows users to
issue SCSI PERSISTENT RESERVE IN / OUT commands.
sbin/camcontrol/Makefile:
Add persist.c.
sbin/camcontrol/persist.c:
New persistent reservation support for camcontrol(8).
We have support for all known operation modes for PERSISTENT RESERVE
IN and PERSISTENT RESERVE OUT.
exceptions noted above.
sbin/camcontrol/camcontrol.8:
Document the new 'persist' subcommand.
In the section on the Transport ID (-I) option, explain what
Transport IDs for each protocol should look like. At some point
some of this information could probably get moved off in a
separate man page, either on Transport IDs alone or a man page
documenting the Transport ID parsing code.
Add a number of examples of persistent reservation commands.
Persistent Reservations are complex enough that the average user
probably won't be able to get the commands exactly right by just
reading the man page. These examples show a few basic and
advanced examples of how to use persistent reservations.
sbin/camcontrol/camcontrol.h:
Move the definition for camcontrol_optret here, so we can use it
for the persistent reservation code.
Add a definition for the new scsipersist() function.
sbin/camcontrol/camcontrol.c:
Add 'persist' to the list of subcommands.
Document 'persist' in the help text.
sys/cam/scsi/scsi_all.c:
Add the scsi_persistent_reserve_in() and
scsi_persistent_reserve_out() CCB building functions.
Add a new function, scsi_transportid_sbuf(). This takes a
SCSI Transport ID (documented in SPC-4), and prints it to
an sbuf(9). There are some transports (like ATA, USB, and
SSA) for which there is no transport defined. We need to
come up with a reasonable thing to do if we're presented
with a Transport ID that claims to be for one of those
protocols.
Add new routines scsi_get_nv() and scsi_nv_to_str().
These functions do a table lookup to go between a string and an
integer. There are lots of table lookups needed in the
persistent reservation code in camcontrol(8).
Add a new function, scsi_parse_transportid(), along with leaf node
functions to parse:
FC, 1394 and SAS (scsi_parse_transportid_64bit())
iSCSI (scsi_parse_transportid_iscsi())
SPI (scsi_parse_transportid_spi())
RDMA (scsi_parse_transportid_rdma())
PCIe (scsi_parse_transportid_sop())
Transport IDs. Given a string with the general form proto,id these
functions create a SCSI Transport ID structure.
sys/cam/scsi/scsi_all.h:
Update the various persistent reservation data structures to
SPC4r36l, but also rename some fields that were previously
obsolete with the proper names from older SCSI specs. This
allows using older, obsolete persistent reservation types when
desired.
Add function prototypes for the new persistent reservation CCB
building functions.
Add a data strucure for the READ FULL STATUS service action
of the PERSISTENT RESERVE IN command.
Add Transport ID structures for all protocols described in SPC-4.
Add a new series of SCSI_PROTO_XXX definitions, and
redefine other defines in terms of these new definitions.
Add a prototype for scsi_transportid_sbuf().
Change a couple of "obsolete" persistent reservation data
structure fields into something more meaningful, based on
what the field was called when it was defined in the spec.
(e.g. SPC, SPC-2, etc.)
Create a new define, SPRI_MAX_LEN, for the maximum allocation
length allowed for the PERSISTENT RESERVE IN command.
Add data structures and enumerations for the new name/value
translation functions.
Add data structures for SCSI over PCIe Routing IDs.
Bring the PERSISTENT RESERVE OUT Register and Move parameter list
structure (struct scsi_per_res_out_parms) up to date with SPC-4.
Add a data structure for the transport IDs that can optionally be
appended to the basic PERSISTENT RESERVE OUT parameter list.
Move SCSI protocol macro definitions out of the VPD page 0x83
definition and combine them with the more up to date protocol
definitions higher in the file.
Add function prototypes for scsi_nv_to_str(), scsi_get_nv(),
scsi_parse_transportid_64bit(), scsi_parse_transportid_spi(),
scsi_parse_transportid_rdma(), scsi_parse_transportid_iscsi(),
scsi_parse_transportid_sop(), and scsi_parse_transportid().

Add persistent reservation support to camcontrol(8).
camcontrol(8) now supports a new 'persist' subcommand that allows users to
issue SCSI PERSISTENT RESERVE IN / OUT commands.
sbin/camcontrol/Makefile:
Add persist.c.
sbin/camcontrol/persist.c:
New persistent reservation support for camcontrol(8).
We have support for all known operation modes for PERSISTENT RESERVE
IN and PERSISTENT RESERVE OUT.
exceptions noted above.
sbin/camcontrol/camcontrol.8:
Document the new 'persist' subcommand.
In the section on the Transport ID (-I) option, explain what
Transport IDs for each protocol should look like. At some point
some of this information could probably get moved off in a
separate man page, either on Transport IDs alone or a man page
documenting the Transport ID parsing code.
Add a number of examples of persistent reservation commands.
Persistent Reservations are complex enough that the average user
probably won't be able to get the commands exactly right by just
reading the man page. These examples show a few basic and
advanced examples of how to use persistent reservations.
sbin/camcontrol/camcontrol.h:
Move the definition for camcontrol_optret here, so we can use it
for the persistent reservation code.
Add a definition for the new scsipersist() function.
sbin/camcontrol/camcontrol.c:
Add 'persist' to the list of subcommands.
Document 'persist' in the help text.
sys/cam/scsi/scsi_all.c:
Add the scsi_persistent_reserve_in() and
scsi_persistent_reserve_out() CCB building functions.
Add a new function, scsi_transportid_sbuf(). This takes a
SCSI Transport ID (documented in SPC-4), and prints it to
an sbuf(9). There are some transports (like ATA, USB, and
SSA) for which there is no transport defined. We need to
come up with a reasonable thing to do if we're presented
with a Transport ID that claims to be for one of those
protocols.
Add new routines scsi_get_nv() and scsi_nv_to_str().
These functions do a table lookup to go between a string and an
integer. There are lots of table lookups needed in the
persistent reservation code in camcontrol(8).
Add a new function, scsi_parse_transportid(), along with leaf node
functions to parse:
FC, 1394 and SAS (scsi_parse_transportid_64bit())
iSCSI (scsi_parse_transportid_iscsi())
SPI (scsi_parse_transportid_spi())
RDMA (scsi_parse_transportid_rdma())
PCIe (scsi_parse_transportid_sop())
Transport IDs. Given a string with the general form proto,id these
functions create a SCSI Transport ID structure.
sys/cam/scsi/scsi_all.h:
Update the various persistent reservation data structures to
SPC4r36l, but also rename some fields that were previously
obsolete with the proper names from older SCSI specs. This
allows using older, obsolete persistent reservation types when
desired.
Add function prototypes for the new persistent reservation CCB
building functions.
Add a data strucure for the READ FULL STATUS service action
of the PERSISTENT RESERVE IN command.
Add Transport ID structures for all protocols described in SPC-4.
Add a new series of SCSI_PROTO_XXX definitions, and
redefine other defines in terms of these new definitions.
Add a prototype for scsi_transportid_sbuf().
Change a couple of "obsolete" persistent reservation data
structure fields into something more meaningful, based on
what the field was called when it was defined in the spec.
(e.g. SPC, SPC-2, etc.)
Create a new define, SPRI_MAX_LEN, for the maximum allocation
length allowed for the PERSISTENT RESERVE IN command.
Add data structures and enumerations for the new name/value
translation functions.
Add data structures for SCSI over PCIe Routing IDs.
Bring the PERSISTENT RESERVE OUT Register and Move parameter list
structure (struct scsi_per_res_out_parms) up to date with SPC-4.
Add a data structure for the transport IDs that can optionally be
appended to the basic PERSISTENT RESERVE OUT parameter list.
Move SCSI protocol macro definitions out of the VPD page 0x83
definition and combine them with the more up to date protocol
definitions higher in the file.
Add function prototypes for scsi_nv_to_str(), scsi_get_nv(),
scsi_parse_transportid_64bit(), scsi_parse_transportid_spi(),
scsi_parse_transportid_rdma(), scsi_parse_transportid_iscsi(),
scsi_parse_transportid_sop(), and scsi_parse_transportid().

|
|
|
|
|
.Dq sop,
|
|
|
|
|
followed by a PCIe Routing ID.
|
|
|
|
|
The Routing ID consists of a bus, device and function or in the alternate
|
|
|
|
|
form, a bus and function.
|
|
|
|
|
The bus must be in the range of 0 to 255 inclusive and the device must be
|
|
|

in the range of 0 to 31 inclusive.
|
|
|
|
|
The function must be in the range of 0 to 7 inclusive if the standard form
|
|
|
|
|
is used, and in the range of 0 to 255 inclusive if the alternate form is
|
|
|
|
|

Add a number of examples of persistent reservation commands.
Persistent Reservations are complex enough that the average user
probably won't be able to get the commands exactly right by just
reading the man page. These examples show a few basic and
advanced examples of how to use persistent reservations.
sbin/camcontrol/camcontrol.h:
Move the definition for camcontrol_optret here, so we can use it
for the persistent reservation code.
Add a definition for the new scsipersist() function.
sbin/camcontrol/camcontrol.c:
Add 'persist' to the list of subcommands.
Document 'persist' in the help text.
sys/cam/scsi/scsi_all.c:
Add the scsi_persistent_reserve_in() and
scsi_persistent_reserve_out() CCB building functions.
Add a new function, scsi_transportid_sbuf(). This takes a
SCSI Transport ID (documented in SPC-4), and prints it to
an sbuf(9). There are some transports (like ATA, USB, and
SSA) for which there is no transport defined. We need to
come up with a reasonable thing to do if we're presented
with a Transport ID that claims to be for one of those
protocols.
Add new routines scsi_get_nv() and scsi_nv_to_str().
These functions do a table lookup to go between a string and an
integer. There are lots of table lookups needed in the
persistent reservation code in camcontrol(8).
Add a new function, scsi_parse_transportid(), along with leaf node
functions to parse:
FC, 1394 and SAS (scsi_parse_transportid_64bit())
iSCSI (scsi_parse_transportid_iscsi())
SPI (scsi_parse_transportid_spi())
RDMA (scsi_parse_transportid_rdma())
PCIe (scsi_parse_transportid_sop())
Transport IDs. Given a string with the general form proto,id these
functions create a SCSI Transport ID structure.
sys/cam/scsi/scsi_all.h:
Update the various persistent reservation data structures to
SPC4r36l, but also rename some fields that were previously
obsolete with the proper names from older SCSI specs. This
allows using older, obsolete persistent reservation types when
desired.
Add function prototypes for the new persistent reservation CCB
building functions.
Add a data strucure for the READ FULL STATUS service action
of the PERSISTENT RESERVE IN command.
Add Transport ID structures for all protocols described in SPC-4.
Add a new series of SCSI_PROTO_XXX definitions, and
redefine other defines in terms of these new definitions.
Add a prototype for scsi_transportid_sbuf().
Change a couple of "obsolete" persistent reservation data
structure fields into something more meaningful, based on
what the field was called when it was defined in the spec.
(e.g. SPC, SPC-2, etc.)
Create a new define, SPRI_MAX_LEN, for the maximum allocation
length allowed for the PERSISTENT RESERVE IN command.
Add data structures and enumerations for the new name/value
translation functions.
Add data structures for SCSI over PCIe Routing IDs.
Bring the PERSISTENT RESERVE OUT Register and Move parameter list
structure (struct scsi_per_res_out_parms) up to date with SPC-4.
Add a data structure for the transport IDs that can optionally be
appended to the basic PERSISTENT RESERVE OUT parameter list.
Move SCSI protocol macro definitions out of the VPD page 0x83
definition and combine them with the more up to date protocol
definitions higher in the file.
Add function prototypes for scsi_nv_to_str(), scsi_get_nv(),
scsi_parse_transportid_64bit(), scsi_parse_transportid_spi(),
scsi_parse_transportid_rdma(), scsi_parse_transportid_iscsi(),
scsi_parse_transportid_sop(), and scsi_parse_transportid().

Add a number of interrelated CAM feature enhancements and bug fixes.
NOTE: These changes will require recompilation of any userland
applications, like cdrecord, xmcd, etc., that use the CAM passthrough
interface. A make world is recommended.
camcontrol.[c8]:
- We now support two new commands, "tags" and "negotiate".
- The tags commands allows users to view the number of tagged
openings for a device as well as a number of other related
parameters, and it allows users to set tagged openings for
a device.
- The negotiate command allows users to enable and disable
disconnection and tagged queueing, set sync rates, offsets
and bus width. Note that not all of those features are
available for all controllers. Only the adv, ahc, and ncr
drivers fully support all of the features at this point.
Some cards do not allow the setting of sync rates, offsets and
the like, and some of the drivers don't have any facilities to
do so. Some drivers, like the adw driver, only support enabling
or disabling sync negotiation, but do not support setting sync
rates.
- new description in the camcontrol man page of how to format a disk
- cleanup of the camcontrol inquiry command
- add support in the 'devlist' command for skipping unconfigured devices if
-v was not specified on the command line.
- make use of the new base_transfer_speed in the path inquiry CCB.
- fix CCB bzero cases
cam_xpt.c, cam_sim.[ch], cam_ccb.h:
- new flags on many CCB function codes to designate whether they're
non-immediate, use a user-supplied CCB, and can only be passed from
userland programs via the xpt device. Use these flags in the transport
layer and pass driver to categorize CCBs.
- new flag in the transport layer device matching code for device nodes
that indicates whether a device is unconfigured
- bump the CAM version from 0x10 to 0x11
- Change the CAM ioctls to use the version as their group code, so we can
force users to recompile code even when the CCB size doesn't change.
- add + fill in a new value in the path inquiry CCB, base_transfer_speed.
Remove a corresponding field from the cam_sim structure, and add code to
every SIM to set this field to the proper value.
- Fix the set transfer settings code in the transport layer.
scsi_cd.c:
- make some variables volatile instead of just casting them in various
places
- fix a race condition in the changer code
- attach unless we get a "logical unit not supported" error. This should
fix all of the cases where people have devices that return weird errors
when they don't have media in the drive.
scsi_da.c:
- attach unless we get a "logical unit not supported" error
scsi_pass.c:
- for immediate CCBs, just malloc a CCB to send the user request in. This
gets rid of the 'held' count problem in camcontrol tags.
scsi_pass.h:
- change the CAM ioctls to use the CAM version as their group code.
adv driver:
- Allow changing the sync rate and offset separately.
adw driver
- Allow changing the sync rate and offset separately.
aha driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
ahc driver:
- Allow setting offset and sync rate separately
bt driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
NCR driver:

XPT_GET_TRAN_SETTINGS CCBs.

cam_xpt.c, cam_sim.[ch], cam_ccb.h:
- new flags on many CCB function codes to designate whether they're
non-immediate, use a user-supplied CCB, and can only be passed from
userland programs via the xpt device. Use these flags in the transport
layer and pass driver to categorize CCBs.
- new flag in the transport layer device matching code for device nodes
that indicates whether a device is unconfigured
- bump the CAM version from 0x10 to 0x11
- Change the CAM ioctls to use the version as their group code, so we can
force users to recompile code even when the CCB size doesn't change.
- add + fill in a new value in the path inquiry CCB, base_transfer_speed.
Remove a corresponding field from the cam_sim structure, and add code to
every SIM to set this field to the proper value.
- Fix the set transfer settings code in the transport layer.
scsi_cd.c:
- make some variables volatile instead of just casting them in various
places
- fix a race condition in the changer code
- attach unless we get a "logical unit not supported" error. This should
fix all of the cases where people have devices that return weird errors
when they don't have media in the drive.
scsi_da.c:
- attach unless we get a "logical unit not supported" error
scsi_pass.c:
- for immediate CCBs, just malloc a CCB to send the user request in. This
gets rid of the 'held' count problem in camcontrol tags.
scsi_pass.h:
- change the CAM ioctls to use the CAM version as their group code.
adv driver:
- Allow changing the sync rate and offset separately.

- Allow changing the sync rate and offset separately.

- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
ahc driver:

Add a number of interrelated CAM feature enhancements and bug fixes.
NOTE: These changes will require recompilation of any userland
applications, like cdrecord, xmcd, etc., that use the CAM passthrough
interface. A make world is recommended.
camcontrol.[c8]:
- We now support two new commands, "tags" and "negotiate".
- The tags commands allows users to view the number of tagged
openings for a device as well as a number of other related
parameters, and it allows users to set tagged openings for
a device.
- The negotiate command allows users to enable and disable
disconnection and tagged queueing, set sync rates, offsets
and bus width. Note that not all of those features are
available for all controllers. Only the adv, ahc, and ncr

Test Unit Ready command to make the settings take effect.

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.

Transport IDs for each protocol should look like. At some point
some of this information could probably get moved off in a
separate man page, either on Transport IDs alone or a man page
documenting the Transport ID parsing code.
Add a number of examples of persistent reservation commands.
Persistent Reservations are complex enough that the average user
probably won't be able to get the commands exactly right by just
reading the man page. These examples show a few basic and
advanced examples of how to use persistent reservations.
sbin/camcontrol/camcontrol.h:

Document 'persist' in the help text.
sys/cam/scsi/scsi_all.c:
Add the scsi_persistent_reserve_in() and
scsi_persistent_reserve_out() CCB building functions.
Add a new function, scsi_transportid_sbuf(). This takes a
SCSI Transport ID (documented in SPC-4), and prints it to
an sbuf(9). There are some transports (like ATA, USB, and
SSA) for which there is no transport defined. We need to
come up with a reasonable thing to do if we're presented
with a Transport ID that claims to be for one of those
protocols.
Add new routines scsi_get_nv() and scsi_nv_to_str().
These functions do a table lookup to go between a string and an
integer. There are lots of table lookups needed in the
persistent reservation code in camcontrol(8).
Add a new function, scsi_parse_transportid(), along with leaf node
functions to parse:
FC, 1394 and SAS (scsi_parse_transportid_64bit())
iSCSI (scsi_parse_transportid_iscsi())
SPI (scsi_parse_transportid_spi())
RDMA (scsi_parse_transportid_rdma())
PCIe (scsi_parse_transportid_sop())
Transport IDs. Given a string with the general form proto,id these
functions create a SCSI Transport ID structure.
sys/cam/scsi/scsi_all.h:
Update the various persistent reservation data structures to
SPC4r36l, but also rename some fields that were previously
obsolete with the proper names from older SCSI specs. This
allows using older, obsolete persistent reservation types when
desired.
Add function prototypes for the new persistent reservation CCB
building functions.
Add a data strucure for the READ FULL STATUS service action
of the PERSISTENT RESERVE IN command.
Add Transport ID structures for all protocols described in SPC-4.
Add a new series of SCSI_PROTO_XXX definitions, and
redefine other defines in terms of these new definitions.
Add a prototype for scsi_transportid_sbuf().
Change a couple of "obsolete" persistent reservation data
structure fields into something more meaningful, based on
what the field was called when it was defined in the spec.
(e.g. SPC, SPC-2, etc.)
Create a new define, SPRI_MAX_LEN, for the maximum allocation
length allowed for the PERSISTENT RESERVE IN command.
Add data structures and enumerations for the new name/value
translation functions.
Add data structures for SCSI over PCIe Routing IDs.
Bring the PERSISTENT RESERVE OUT Register and Move parameter list
structure (struct scsi_per_res_out_parms) up to date with SPC-4.
Add a data structure for the transport IDs that can optionally be
appended to the basic PERSISTENT RESERVE OUT parameter list.
Move SCSI protocol macro definitions out of the VPD page 0x83
definition and combine them with the more up to date protocol
definitions higher in the file.
Add function prototypes for scsi_nv_to_str(), scsi_get_nv(),
scsi_parse_transportid_64bit(), scsi_parse_transportid_spi(),
scsi_parse_transportid_rdma(), scsi_parse_transportid_iscsi(),
scsi_parse_transportid_sop(), and scsi_parse_transportid().

Add persistent reservation support to camcontrol(8).

issue SCSI PERSISTENT RESERVE IN / OUT commands.
sbin/camcontrol/Makefile:
Add persist.c.
sbin/camcontrol/persist.c:
New persistent reservation support for camcontrol(8).
We have support for all known operation modes for PERSISTENT RESERVE
IN and PERSISTENT RESERVE OUT.
exceptions noted above.
sbin/camcontrol/camcontrol.8:
Document the new 'persist' subcommand.
In the section on the Transport ID (-I) option, explain what
Transport IDs for each protocol should look like. At some point
some of this information could probably get moved off in a
separate man page, either on Transport IDs alone or a man page
documenting the Transport ID parsing code.
Add a number of examples of persistent reservation commands.
Persistent Reservations are complex enough that the average user
probably won't be able to get the commands exactly right by just
reading the man page. These examples show a few basic and
advanced examples of how to use persistent reservations.
sbin/camcontrol/camcontrol.h:
Move the definition for camcontrol_optret here, so we can use it
for the persistent reservation code.
Add a definition for the new scsipersist() function.
sbin/camcontrol/camcontrol.c:
Add 'persist' to the list of subcommands.
Document 'persist' in the help text.
sys/cam/scsi/scsi_all.c:
Add the scsi_persistent_reserve_in() and
scsi_persistent_reserve_out() CCB building functions.
Add a new function, scsi_transportid_sbuf(). This takes a
SCSI Transport ID (documented in SPC-4), and prints it to
an sbuf(9). There are some transports (like ATA, USB, and
SSA) for which there is no transport defined. We need to
come up with a reasonable thing to do if we're presented
with a Transport ID that claims to be for one of those
protocols.
Add new routines scsi_get_nv() and scsi_nv_to_str().
These functions do a table lookup to go between a string and an
integer. There are lots of table lookups needed in the
persistent reservation code in camcontrol(8).
Add a new function, scsi_parse_transportid(), along with leaf node
functions to parse:
FC, 1394 and SAS (scsi_parse_transportid_64bit())
iSCSI (scsi_parse_transportid_iscsi())
SPI (scsi_parse_transportid_spi())
RDMA (scsi_parse_transportid_rdma())
PCIe (scsi_parse_transportid_sop())
Transport IDs. Given a string with the general form proto,id these
functions create a SCSI Transport ID structure.
sys/cam/scsi/scsi_all.h:
Update the various persistent reservation data structures to
SPC4r36l, but also rename some fields that were previously
obsolete with the proper names from older SCSI specs. This
allows using older, obsolete persistent reservation types when
desired.
Add function prototypes for the new persistent reservation CCB
building functions.
Add a data strucure for the READ FULL STATUS service action
of the PERSISTENT RESERVE IN command.
Add Transport ID structures for all protocols described in SPC-4.
Add a new series of SCSI_PROTO_XXX definitions, and
redefine other defines in terms of these new definitions.
Add a prototype for scsi_transportid_sbuf().
Change a couple of "obsolete" persistent reservation data
structure fields into something more meaningful, based on
what the field was called when it was defined in the spec.
(e.g. SPC, SPC-2, etc.)
Create a new define, SPRI_MAX_LEN, for the maximum allocation
length allowed for the PERSISTENT RESERVE IN command.
Add data structures and enumerations for the new name/value
translation functions.
Add data structures for SCSI over PCIe Routing IDs.
Bring the PERSISTENT RESERVE OUT Register and Move parameter list
structure (struct scsi_per_res_out_parms) up to date with SPC-4.
Add a data structure for the transport IDs that can optionally be
appended to the basic PERSISTENT RESERVE OUT parameter list.
Move SCSI protocol macro definitions out of the VPD page 0x83
definition and combine them with the more up to date protocol
definitions higher in the file.
Add function prototypes for scsi_nv_to_str(), scsi_get_nv(),
scsi_parse_transportid_64bit(), scsi_parse_transportid_spi(),
scsi_parse_transportid_rdma(), scsi_parse_transportid_iscsi(),
scsi_parse_transportid_sop(), and scsi_parse_transportid().

Add a number of interrelated CAM feature enhancements and bug fixes.
NOTE: These changes will require recompilation of any userland
applications, like cdrecord, xmcd, etc., that use the CAM passthrough
interface. A make world is recommended.
camcontrol.[c8]:
- We now support two new commands, "tags" and "negotiate".
- The tags commands allows users to view the number of tagged
openings for a device as well as a number of other related
parameters, and it allows users to set tagged openings for
a device.
- The negotiate command allows users to enable and disable
disconnection and tagged queueing, set sync rates, offsets
and bus width. Note that not all of those features are
available for all controllers. Only the adv, ahc, and ncr
drivers fully support all of the features at this point.
Some cards do not allow the setting of sync rates, offsets and
the like, and some of the drivers don't have any facilities to
do so. Some drivers, like the adw driver, only support enabling
or disabling sync negotiation, but do not support setting sync
rates.
- new description in the camcontrol man page of how to format a disk
- cleanup of the camcontrol inquiry command
- add support in the 'devlist' command for skipping unconfigured devices if
-v was not specified on the command line.
- make use of the new base_transfer_speed in the path inquiry CCB.
- fix CCB bzero cases
cam_xpt.c, cam_sim.[ch], cam_ccb.h:
- new flags on many CCB function codes to designate whether they're
non-immediate, use a user-supplied CCB, and can only be passed from
userland programs via the xpt device. Use these flags in the transport
layer and pass driver to categorize CCBs.
- new flag in the transport layer device matching code for device nodes
that indicates whether a device is unconfigured
- bump the CAM version from 0x10 to 0x11
- Change the CAM ioctls to use the version as their group code, so we can
force users to recompile code even when the CCB size doesn't change.
- add + fill in a new value in the path inquiry CCB, base_transfer_speed.
Remove a corresponding field from the cam_sim structure, and add code to
every SIM to set this field to the proper value.
- Fix the set transfer settings code in the transport layer.
scsi_cd.c:
- make some variables volatile instead of just casting them in various
places
- fix a race condition in the changer code
- attach unless we get a "logical unit not supported" error. This should
fix all of the cases where people have devices that return weird errors
when they don't have media in the drive.
scsi_da.c:
- attach unless we get a "logical unit not supported" error
scsi_pass.c:
- for immediate CCBs, just malloc a CCB to send the user request in. This
gets rid of the 'held' count problem in camcontrol tags.
scsi_pass.h:
- change the CAM ioctls to use the CAM version as their group code.
adv driver:
- Allow changing the sync rate and offset separately.
adw driver
- Allow changing the sync rate and offset separately.
aha driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
ahc driver:
- Allow setting offset and sync rate separately
bt driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
NCR driver:
- Fix the ultra/ultra 2 negotiation bug
- allow setting both the sync rate and offset separately
Other HBA drivers:
- Put code in to set the base_transfer_speed field for
XPT_GET_TRAN_SETTINGS CCBs.
