de649cc42c Really support Ultra-2 chips. Symbios redefined a register that
was available to the programmer to hold chip state information:

Use the SDID register instead of CTEST3. This change actually
simplifies the SCRIPTS code, but I'm not absolutely sure, that
it is OK for all variants of NCR chips around and all device
combinations. I have had this code running on several systems
with 53c810, 875 and 895 controllers for several months.

579f45fa60 Simplify the COMPAT_PCI_DRIVER/DATA_SET hack. We can add:
#define COMPAT_PCI_DRIVER(name,data) DATA_SET(pcidevice_set,data)
.. to 2.2.x and 3.x if people think it's worth it.  Driver writers can do
this if it's not defined.  (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)

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.

2127f26023 Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

761fe626ea Really correct ncr_freeze_devq now. We scan backwards from the current
insertion point into the start queue looking for entries to remove and
mark them with the 'skip' address, recording the entry furthest from the
insertion point that needs to be removed.  We then go through a second
loop starting at the furthest entry to be removed and compress the start
queue.  The old algorithm started at (old insert point + 1) and wrapped
through the whole queue which would end up moving the start position in
the queue out from under the nose of the scrip processor.

348811e078 Fix a bug in ncr_freeze_devq() which is called when we see a queue
full condition or other error which requires us to purge the
controller's start queue of transactions for a particular device.
We were relying on the NCR CCB's program address to cause the
script engine to skip to the next entry in the queue even though
the CCB is freed (and its program address switched to the idle
loop) by this action.  We now set the address in the start queue
to be the "skip" function directly.

c41141b002 Fixed the formatting of some tables (mainly the one produced by ps
in ddb) which I broke by changing %8[l]x to %8p.  Hacked the central
printf routine to not add an "0x" prefix for %p formats if the field
width is nonzero.  The tables are still horribly misformatted on
64-bit machines.

Use %p instead of %8p to print pointers when the field width isn't
important.

The size mismatch did not matter due to sufficient padding at the end
of the structure that holds time stamps (there is an unused member).

The fix suggested by Bruce Evans used "sizeof (ticks_t)", but I prefer
to use "sizeof ticks", and didn't seem to object in his last mail on

227ee8a188 Eradicate the variable "time" from the kernel, using various measures.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

Most uses of time.tv_sec now uses the new variable time_second instead.

gettime() changed to getmicrotime(0.

Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).

A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.

Add a new nfs_curusec() function.

Mark a couple of bogosities involving the now disappeard time variable.

Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.

Change profiling in ncr.c to use ticks instead of time.  Resolution is
the same.

Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call
hzto() which subtracts time" sequences.

71b8fb2a93 Fix problem with early revision 53c825a and 53c875 chips, which
could cause a solid system lockup in the driver attach:

These chips do not abort an access to the internal SRAM, when
the driver set the software reset bit in the istat register. But
the chip will never acknowledge the requested PCI bus transfer
in the situation, causing an infinite wait and a lockout of other
bus-masters.

The problem has been reported for rev 0x11 of the 53c825a and
rev 0x01 of the 53c875.
Revisions 0x13 of the 53c825a and 0x03 of the 53c875 are known

Fix support of 16 targets for WIDE SCSI.

Disable bus reset in case no progress is made for too long ("ncr dead"
message), which did not work too well with scanners and other slow devices.

23da20014a Set clock prescale based on BIOS supplied value instead of trying to
calculate an optimum value from (constant) parameters.
This should set the SCNTL3 register of the 53c860 and 53c875 to twice
the divider it used to be, since cards based on those chips seem to use
an 80MHz clock instead of the Clock Doubler feature and a 40MHz clock.

d8a8289c5a Send out a period of "0" if negotiating asynchronous transfers (offset = 0).
A value of "255" used to be sent, and though it should not matter, there

ede8dc43a2 Fixed unsigned longs that should have been vm_offset_t.
vm_offset_t is currently unsigned long but should probably be plain
unsigned for i386's to match the choice of minimal types to represent
for fixed-width types in Lite2.  Anyway, it shouldn't be assumed
to be unsigned long.

I only fixed the type mismatches that were detected when I changed
vm_offset_t to unsigned.  Only pointer type mismatches were detected.

078d5aeeed If FAILSAFE is defined, then:
- Do not enable tagged commands by default
- Probe only 1 LUN
- Do not negotiate sync. transfer with CDROM drives

Defining FAILSAFE will result in a driver that will tolerate
marginal hardware for the price of a slight loss of performance
It is intended for use in install kernels.
