a7454a8878 Make the change similar to that suggested by Nick Hibma to avoid divide by
zero traps. I actually can't believe that this compiler is *sooooo* stupid
that it did a divide when there was 1024L*1024L instead of a right shift by
20. When we get quad type modifiers in kernel printf we can change to this
too (to avoid overflow on > terabyte disk sizes).

be done in future commits.

2447bec829 Simplify cdevsw registration.
The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it.  cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.

cdevsw_add() will print an message if the d_maj field looks bogus.

Remove nblkdev and nchrdev variables.  Most places they were used
bogusly.  Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.

Move bdevsw() and devsw() functions to kern/kern_conf.c

Bump __FreeBSD_version to 400006

This commit removes:
        72 bogus makedev() calls
        26 bogus SYSINIT functions

87cfaf0e1f Add the XPT_PATH_STATS and XPT_GDEV_STATS function codes. These ccb
types allow the reporting of error counts and other statistics.  Currently
we provide information on the last BDR or bus reset as well as active
transaction inforamtion, but this will be expanded as more information is
added to aid in error recovery.

Use the 'last reset' information to better handle bus settle delays.
Peripheral drivers now control whether a bus settle delay occurs and
for how long.  This allows target mode peripheral drivers to avoid
having their device queue frozen by the XPT for what shoudl only be
initiator type behavior.

Don't perform a bus reset if the target device is incapable of performing
transfer negotiation (e.g. Fiber Channel).

If we don't perform a bus reset but the controller is capable of transfer
negotiations, force negotiations on the first transaction to go to the
device.  This ensures that we aren't tripped up by a left over negotiation
from the prom, BIOS, loader, etc.

Add a default async handler funstion to cam_periph.c to remove duplicated
code in all initiator type peripheral drivers.

Allow mapping of XPT_CONT_TARGET_IO ccbs from userland.  They are
itentical to XPT_SCSI_IO ccbs as far as data mapping is concerned.

bd1b9cb70f Add a SA_FLAG_COMP_SUPP flag (to quirk compression as
SUPPORTED). Add a SA_FLAG_TAPE_FROZEN for (see below).
Add a queue_count field to softc.

Add HP T20* Travan-5 like tape device as a FIXED/512 type device.
Works for me. Add TANDBERG SLR5 as a variable SA_QUIRK_1FM device.
Change VIPER 2525 to 1024 byte blocksize. It's possible other
drives should change too, but see below..

Change argument to sagetparams to be pointer to a sa_comp_t union-
this can be either a DATA COMPRESSION or a DEVICE CONFIGURATION
page. In general compression now tries to use the DATA COMPRESSION
page and if that fails tries the DEVICE CONFIGURATION page.

Change close routine to not rewind tape if there's a failure in either
writing filemarks or in backing over one of two filemarks for a 2FM
at EOT tape- instead mark the tape as 'frozen' and print a message
saying that either an OFFLINE or REWIND or an MTEOM command is needed
to clear this state (all bring certainty back to tape position). Fix
sastrategy to not allow I/O to a frozen tape.

Add MTIOCGETEOTMODEL/MTIOCSETEOTMODEL ioctls that get and set the EOT
model for a tape drive (you can now dynamically change whether it's
a 2 FM @ EOT or 1FM at EOT tape device). This ought to give folks
something to handle the QIC drives we don't know about. Correctly propagate
record of compression algorithm back. Clear FROZEN flag for EOM, REWIND
and OFFLINE (and RETENSION and ERASE) cases.

Fix an egregious bug in sadone that had left the device queue frozen
for deferred (for fixed mode case) errors.

Add comment in samount about how useless the test unit ready is for
invalidating a mount (this has to be fixed later).

Fix residual calculation (per Eivind) in saerror so that negative values
for tape records being too large for the supplied buffer get caught. Do
some other saerrro cleanup.

50711c71c9 Add a facility in the CAM error handling code to retry selection timeouts.
If the client requests that the error recovery code retry a selection
timeout, it will be retried after half a second.  The delay is to give the
device time to recover.

For most of these drivers, I only added selection timeout retries where
they were also retrying unit attention type errors.  The sa(4) driver calls
saerror() in a number of places, but most of them don't request retrying
unit attentions.

Also, bump the default minimum CD changer timeout from 2 to 5 seconds and
the maximum timeout from 10 to 15 seconds.  Some Pioneer changers seem to
have trouble with the shorter timeout.

9deea8574e 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.

tagged queueing is disabled for both.

Also, update the comment for the Western Digital Enterprise drives to note

2a888f938e Add a prioritization field to the devstat_add_entry() call so that
peripheral drivers can determine where in the devstat(9) list they are
inserted.

This requires recompilation of libdevstat, systat, vmstat, rpc.rstatd, and
any ports that depend on the devstat code, since the size of the devstat
structure has changed.  The devstat version number has been incremented as
well to reflect the change.

This sorts devices in the devstat list in "more interesting" to "less
interesting" order.  So, for instance, da devices are now more important
than floppy drives, and so will appear before floppy drives in the default
output from systat, iostat, vmstat, etc.

The order of devices is, for now, kept in a central table in devicestat.h.
If individual drivers were able to make a meaningful decision on what
priority they should be at attach time, we could consider splitting the
priority information out into the various drivers.  For now, though, they
have no way of knowing that, so it's easier to put them in an easy to find
table.

Also, move the checkversion() call in vmstat(8) to a more logical place.

Thanks to Bruce and David O'Brien for suggestions, for reviewing this, and
for putting up with the long time it has taken me to commit it.  Bruce did
object somewhat to the central priority table (he would rather the
priorities be distributed in each driver), so his objection is duly noted
here.
