Replace the a.out emulation of 'struct linker_set' with something
a little more flexible. <sys/linker_set.h> now provides macros for
accessing elements and completely hides the implementation.
The linker_set.h macros have been on the back burner in various
forms since 1998 and has ideas and code from Mike Smith (SET_FOREACH()),
John Polstra (ELF clue) and myself (cleaned up API and the conversion
of the rest of the kernel to use it).
The macros declare a strongly typed set. They return elements with the
type that you declare the set with, rather than a generic void *.
For ELF, we use the magic ld symbols (__start_<setname> and
__stop_<setname>). Thanks to Richard Henderson <rth@redhat.com> for the
trick about how to force ld to provide them for kld's.
For a.out, we use the old linker_set struct.
NOTE: the item lists are no longer null terminated. This is why
the code impact is high in certain areas.
The runtime linker has a new method to find the linker set
boundaries depending on which backend format is in use.
linker sets are still module/kld unfriendly and should never be used
for anything that may be modular one day.

Add in a kernel thread for Fibre Channel cards. The purpose of this
thread is to be woken up to clean up after Fibre Channel events
block things. Basically, any FC event that casts doubt on the
location or identify of FC devices blocks the queues. When, and
if, we get the PORT DATABASE CHANGED or NAME SERVER DATABASE CHANGED
async event, we activate the kthread which will then, in full thread
context, re-evaluate the local loop and/or the fabric. When it's
satisfied that things are stable, it can then release the blocked
queues and let commands flow again.
The prior mechanism was a lazy evaluation. That is, the next command
to come down the pipe after change events would pay the full price
for re-evaluation. And if this was done off of a softcall, it really
could hang up the system.
These changes brings the FreeBSD port more in line with the Solaris,
Linux and NetBSD ports. It also, more importantly, gets us being
more proactive about topology changes which could then be reflected
upwards to CAM so that the periph driver can be informed sooner
rather than later when things arrive or depart.

alpha_pci_route_interrupt() requires us to figure out the bus/slot/etc

the built-in 1000baseX interface in the Level 1 LXT1001 chip. The Level 1
PHY comes up with the isolate bit in the control register set by default,
but it also has the autonegotiate bit set. When you tell the xmphy driver
to select IFM_AUTO mode, it sees that the autoneg bit is already on, and
thus doesn't bother updating the control register. However this means that
the isolate bit is never turned off (unless you manually select 1000baseSX
full or half duplex mode, which does result in the control register being
modified and the ISO bit being turned off).
This subtle and unusual behavioral difference stopped me from being able
to receive packets on the SMC9462TX card for several days, since isolating
the PHY disconnects it from the MAC's data interface. The fix is to omit
the 'is the autoneg big set?' test, since it doesn't really provide much
of an optimization anyway.
This commit also updates the xmphy driver to support the Jato/Level 1

and panic in sk_setmulti() at driver load/initialization time.

burrito out before we start.
We now support conjoint status with data for the last CTIO for both Fibre
Channel and SCSI. Leave the old code in place in case we need to go back
(minor 3 line ifdef).
Ultra-ultra important- *don't* set rq->req_seg_count for non-data
target mode requests in isp_pci_dmasetup. D'oh- this is actually
the tag value area for a CTIO. What *was* I thinking? Boy howdy
does both aic7xxx and sym get awfully unhappy when on reconnect
you give them a constant '1' for a tag value.
function- we did it a bit cleaner. We only use this if a CTIO completes with
!CT_OK state. We now have managed to get away without having to poke around
and trying to find the original ATIO- the csio we're using has the tag_id
and lun values with it which is mostly what we need when we do the putback.
Make sure we correctly propagate AT_TQAE->CT_TQAE for tags. Make sure
we call ISP_DMAFREE only if we had DATA to move.
tag is active for an ATIO, and say that you want to reconnect with
a tag value in a CTIO have *never* been exercised until now. This lossage
derived from Solaris code where this stuff originally came from that is
about 7 years old. Amazing.
We now bundle the incoming tag (legal values are 0..256) as the low
16 bits of the ccb_accept_tio's at_tagid while we put the firmware
handle for this ATIO in the top 16 bits- define some macros to make
this cleaner.
Complete some Ansification.
Redo establishment of default SCSI parameters whether or not
we've been compiled for target mode. Unfortunately, the Qlogic
f/w is confused so that if we set all targets to be 'safe' (i.e.,
narrow/async), it will also then report narrow, async if we're
contacted in target mode from that target (acting in initiator
role). D'oh!
Fix ISPCTL_TOGGLE_TMODE to correctly enable the right channel for
dual channel cards. Add some more opcodes. Fix a stupid NULL

Simplify initialization and remove offending DMA channel resets there.
The resets trash whatever is pointed to DMA registers, but at cmi_attach()

skew relative to system clock at 44.1kHz is usually in range 0-25%

aic7xxx_pci.c:
Enable board generation of interrupts only once our handler is
in place and all other setup has occurred.
aic7xxx.c:
More conversion of data types to ahc_* names. tmode_tstate and
tmode_lstate are the latest victims.
Clean up the check condition path by branching early rather
than indenting a giant block of code.
Add support for target mode initiated sync negotiation.
The code has been tested by forcing the feature on for
all devices, but for the moment is left inaccesible until
a decent mechanism for controlling the behavior is complete.
Implementing this feature required the removal of the
old "target message request" mechanism. The old method
required setting one of the 16 bit fields to initiate
negotiation with a particular target. This had the nice
effect of being easy to change the request and have it
effect the next command. We now set the MK_MESSAGE bit
on any new command when negotiation is required. When
the negotiation is successful, we walk through and clean
up the bit on any pending commands. Since we have to walk
the commands to reset the SCSI syncrate values so no additional
work is required. The only drawback of this approach is that
the negotiation is deferred until the next command is queued to
the controller. On the plus side, we regain two bytes of
sequencer scratch ram and 6 sequencer instructions.
When cleaning up a target mode instance, never remove the
"master" target mode state object. The master contains
all of the saved SEEPROM settings that control things like
transfer negotiations. This data will be cloned as the
defaults if a target mode instance is re-instantiated.
Correct a bug in ahc_set_width(). We neglected to update
the pending scbs to reflect the new parameters. Since
wide negotiation is almost always followed by sync
negotiation it is doubtful that this had any real
effect.
When in the target role, don't complain about
"Target Initiated" negotiation requests when an initiator
negotiates with us.
Defer enabling board interrupts until after ahc_intr_enable()
is called.
Pull all info that used to be in ahc_timeout for the FreeBSD
OSM into ahc_dump_card_state(). This info should be printed
out on all platforms.
aic7xxx.h:
Add the SCB_AUTO_NEGOITATE scb flag. This allows us to
discern the reason the MK_MESSAGE flag is set in the hscb
control byte. We only want to clear MK_MESSAGE in
ahc_update_pending_scbs() if the MK_MESSAGE was set due
to an auto transfer negotiation.
Add the auto_negotiate bitfield for each tstate so that
behavior can be controlled for each of our enabled SCSI
IDs.
Use a bus interrupt handler vector in our softc rather
than hard coding the PCI interrupt handler. This makes
it easier to build the different bus attachments to
the aic7xxx driver as modules.
aic7xxx.reg:
Remove the TARGET_MSG_REQUEST definition for sequencer ram.
aic7xxx.seq:
Fix a few target mode bugs:
o If MK_MESSAGE is set in an SCB, transition to
message in phase and notify the kernel so that
message delivery can occur. This is currently
only used for target mode initiated transfer
negotiation.
o Allow a continue target I/O to compile without
executing a status phase or disconnecting. If
we have not been granted the disconnect privledge
but this transfer is larger than MAXPHYS, it may
take several CTIOs to get the job done.
Remove the tests of the TARGET_MSG_REQUEST field in scratch ram.
aic7xxx_freebsd.c:
Add support for CTIOs that don't disconnect. We now defer
the clearing of our pending target state until we see a
CTIO for that device that has completed sucessfully.
Be sure to return early if we are in a target only role
and see an initiator only CCB type in our action routine.
If a CTIO has the CAM_DIS_DISCONNECT flag set, propogate
this flag to the SCB. This flag has no effect if we've
been asked to deliver status as well. We will complete
the command and release the bus in that case.
Handle the new auto_negotiate field in the tstate correctly.
Make sure that SCBs for "immediate" (i.e. to continue a non
disconnected transaction) CTIO requests get a proper mapping
in the SCB lookup table. Without this, we'll complain when
the transaction completes.
Update ahc_timeout() to reflect the changes to ahc_dump_card_state().
aic7xxx_inline.h:
Use ahc->bus_intr rather than ahc_pci_intr.
decode the BIOS and firmware version and announce the board as HP NetRaid.
This has been tested with a NetRaid 3si controller, the BIOS/firmware
printout should also work for other NetRaid controllers but the type
detection for other NetRaids (such as the 1si) will not work due to the
lack of hardware.

We really want to be able to say "auto NWAY", "limited NWAY", and
"no NWAY". Unfortunately, this does not appear to be possible with
the current mediaopt structure.
The fixes the problem of PLAY_BIG not being implemented on
some modern drives.
The problem now is that some old drives use BSD encoding
in the MSF case, which they dont tell, and which is also
not according to spec *sigh*. Hopefully there are not
too many of those still alive, or I hereby grant
license to kill the firmware writers that wrote the mess.
Some of the major changes include:
- The SCSI error handling portion of cam_periph_error() has
been broken out into a number of subfunctions to better
modularize the code that handles the hierarchy of SCSI errors.
As a result, the code is now much easier to read.
- String handling and error printing has been significantly
revamped. We now use sbufs to do string formatting instead
of using printfs (for the kernel) and snprintf/strncat (for
userland) as before.
There is a new catchall error printing routine,
cam_error_print() and its string-based counterpart,
cam_error_string() that allow the kernel and userland
applications to pass in a CCB and have errors printed out
properly, whether or not they're SCSI errors. Among other
things, this helped eliminate a fair amount of duplicate code
in camcontrol.
We now print out more information than before, including
the CAM status and SCSI status and the error recovery action
taken to remedy the problem.
- sbufs are now available in userland, via libsbuf. This
change was necessary since most of the error printing code
is shared between libcam and the kernel.
- A new transfer settings interface is included in this checkin.
This code is #ifdef'ed out, and is primarily intended to aid
discussion with HBA driver authors on the final form the
interface should take. There is example code in the ahc(4)
driver that implements the HBA driver side of the new
interface. The new transfer settings code won't be enabled
until we're ready to switch all HBA drivers over to the new
interface.
src/Makefile.inc1,
lib/Makefile: Add libsbuf. It must be built before libcam,
since libcam uses sbuf routines.
libcam/Makefile: libcam now depends on libsbuf.
libsbuf/Makefile: Add a makefile for libsbuf. This pulls in the
sbuf sources from sys/kern.
bsd.libnames.mk: Add LIBSBUF.
camcontrol/Makefile: Add -lsbuf. Since camcontrol is statically
linked, we can't depend on the dynamic linker
to pull in libsbuf.
camcontrol.c: Use cam_error_print() instead of checking for
CAM_SCSI_STATUS_ERROR on every failed CCB.
sbuf.9: Change the prototypes for sbuf_cat() and
sbuf_cpy() so that the source string is now a
const char *. This is more in line wth the
standard system string functions, and helps
eliminate warnings when dealing with a const
source buffer.
Fix a typo.
cam.c: Add description strings for the various CAM
error status values, as well as routines to
look up those strings.
Add new cam_error_string() and
cam_error_print() routines for userland and
the kernel.
cam.h: Add a new CAM flag, CAM_RETRY_SELTO.
Add enumerated types for the various options
available with cam_error_print() and
cam_error_string().
cam_ccb.h: Add new transfer negotiation structures/types.
Change inq_len in the ccb_getdev structure to
be "reserved". This field has never been
filled in, and will be removed when we next
bump the CAM version.
cam_debug.h: Fix typo.
cam_periph.c: Modularize cam_periph_error(). The SCSI error
handling part of cam_periph_error() is now
in camperiphscsistatuserror() and
camperiphscsisenseerror().
In cam_periph_lock(), increase the reference
count on the periph while we wait for our lock
attempt to succeed so that the periph won't go
away while we're sleeping.
cam_xpt.c: Add new transfer negotiation code. (ifdefed
out)
Add a new function, xpt_path_string(). This
is a string/sbuf analog to xpt_print_path().
scsi_all.c: Revamp string handing and error printing code.
We now use sbufs for much of the string
formatting code. More of that code is shared
between userland the kernel.
scsi_all.h: Get rid of SS_TURSTART, it wasn't terribly
useful in the first place.
Add a new error action, SS_REQSENSE. (Send a
request sense and then retry the command.)
This is useful when the controller hasn't
performed autosense for some reason.
Change the default actions around a bit.
scsi_cd.c,
scsi_da.c,
scsi_pt.c,
scsi_ses.c: SF_RETRY_SELTO -> CAM_RETRY_SELTO. Selection
timeouts shouldn't be covered by a sense flag.
scsi_pass.[ch]: SF_RETRY_SELTO -> CAM_RETRY_SELTO.
Get rid of the last vestiges of a read/write
interface.
libkern/bsearch.c,
sys/libkern.h,
conf/files: Add bsearch.c, which is needed for some of the
new table lookup routines.
aic7xxx_freebsd.c: Define AHC_NEW_TRAN_SETTINGS if
CAM_NEW_TRAN_CODE is defined.
sbuf.h,
subr_sbuf.c: Add the appropriate #ifdefs so sbufs can
compile and run in userland.
Change sbuf_printf() to use vsnprintf()
instead of kvprintf(), which is only available
in the kernel.
Change the source string for sbuf_cpy() and
sbuf_cat() to be a const char *.
Add __BEGIN_DECLS and __END_DECLS around
function prototypes since they're now exported
to userland.
kdump/mkioctls: Include stdio.h before cam.h since cam.h now
includes a function with a FILE * argument.
