and QUEUE FULL cases; this is already done for all BAD_STATUS cases.
Make sure to requeue the SCB in the above cases internally in the driver,
the SCSI layer doesn't know how to deal with it properly.
some devices may not be found if the BIOS (which would normally
do the reset at startup) is disabled. Should really be done from the SCSI
layer.
Implement the SCBUSIORESET ioctl.
This bug is only visible on some disks, and I have verified that it works
correctly on VAX. However, du to the author, it is a problem on other
machines/disks as well. Here's the author's comments:

re-enqueueing an already free ccb.
Prepare the background to have a unique initialization function for
all of the supported host adapters.
Rename a lot of #define in a more sane way.
Move Carriers initialization and defines in adwmcode.{c,h}
Don't lose Carrier nodes in case of a BUS/Chip reset explicitly invoked
after a DMA failure.
XXX - DMA failure still arise when AdvanSys U[2]W host adapters are used
in conjunction with Intel 82443BX Host Bridge/Controller (rev. 0x03).
!?!Have to understand why!?!
values are less machine-dependant. Fixes port-i386/10141, where
spurrious timeouts were being seen.
Also note the line numbers of the timeouts so it can be determined
which is being seen (via __LINE__).
it to determine the boot device: mvme68k, pc532, macppc, ofppc. Those
platforms should be changed to use device_register(). In the mean time,
those ports defined __BROKEN_DK_ESTABLISH.
Add a way to instruct the upper layer to don't bother w/ new requests if/when a device queue is full/busy or the device is unavailabale at that time
Use scsipi_inquiry_data instead of its own inquiry structure
Correctly account for F-port vs. F-port (no FLOGI_ACC) topologies.
Make sure we get a port database entry for the fabric name server.
Preserve fabric logins if the device didn't change across fabric
or port database changes, or the device has already logged into
us (e.g., for target/initiator dual role devices like Veritas
SANbox). Propagate class 3 service parameter changes where devices
can change roles.
Fix all occurrences of setting a sendmarker so that setting it
for one bus on dual bus cards doesn't wipe a pending sendmarker
for other busses on the same card :-;.
Comments added and clarifications made in some of the target mode code.
Only access board memory using the front-end functions.
Add hook for clearing latched interrupts.
Corrent debugging printf of ethertype on LE systems.
Make it possible to us I82586_DEBUG as a kernel option.
Tested on arm26 and mvme68k.
Add a catch for DMA Error which show up on Intel 82443BX Host Bridge/Controller (rev. 0x03). This doesn't fix the problem, but reset the SCSI bus and reinitialize the host adapter
Minor cosmetical changes
Thanks a lot to Greg Oster and Andan Lauber
Increased ADW_MAX_CCB to 63 and ADW_MAX_CARRIER to 253
Print WDTR/SDTR negotiation result per target
Protect AdvISR() inside splbio()/splx() pair
Add a pending queue to keep track of all the CCBs that are being executed by the host adapter.
Rewrote timeout handler in a more efficient way:
After 3 timeout now the SCSI is resetted and all pending queues not completed are now reenqueued in the waiting queue so to get executed just after the BUS Reset (hoping that resetting the SCSI BUS and reinitializing the adapter could solve the problem).
- on a phase mismatch, do byte recovery only if we were in data phase.
Otherwise just clear the fifo.
- Properly handle reject of a sync or wide negotiation.
- Use proper CARDBUS_* macro in if_rl_cardbus.c
- Use product ID read from PCI configuration space rather than from EEPROM
in if_rl_pci.c.
Patch sent from Masanori Kanaoka <kanaoka@ann.hi-ho.ne.jp> and
some cosmetic changes by me.
Fix minor glitches.
Add preliminary support for ASB-3940U3W host adapters; it might work w/ autotermination on.
ASB-3940U3W support is not yet tested due to lack of board.
Contrary to what the rtl8019 docs say, this seems to be necessary.
Observed by myself when implementing non-auto earlier, and independently
complained about by Antti Kante in PR 9962.
- Call bus_dmamap_sync(9) as appropriate.
- Leave only register declarations in rtl81x9reg.h and
split other stuff into rtl81x9var.h.
bus_dma(9) code mostly taken from thorpej's if_rtp.c.
'command slots' in which the host can put command and wait for the script
to start them
- Change siop.c to do full disconnect/reslelect, allowing as much as one
command per target/lun to run in parallel.
- Fix bug in registers init where a board without BIOS would end at
ID 0 (now the driver works on alpha too).
- better handling of messages, sending back a MSG_EXT_SDTR in response to an
incoming MSG_EXT_SDTR, and MSG_MESSAGE_REJECT for unhandled messages.
- fix use of bus_dmamap_sync() and htole32().
- supports shared interrups
- change some int8 and int16 to int, for alpha and mips benefits ( suggested by
Toru Nishimura)
- Use le32toh() on reading rxstat from the Rx DMA buffer.
- rl_read_eeprom() should return EEPROM values in little endian
when caller requires byte-stream data.
bus_dma(9) fixes are still on-going.
XXX rtk on macppc seems to make tons of CRC errors...
XXX Does it work fine on i386 or others?
(the name 'siop' is still being discussed, may change).
Only basic disconnect/reselect for now, no sync/wide negotiation.
Tested with 810A, 875 and 895 on i386 only.
The bus-independant part should also be able to handle the 53c720 and 53c770.
A new driver with enhanced script should appear for the 825/875/895 'soon'.
to BHA_MBX_OFFSET and using it also for mailbox_in. Since all mailboxes
should be placed in a single continuous memory due to a hardware limitation,
an offset of any mailbox can be/should be calculated using a same expression.
- be persistent on initializing interfaces, even if there's manually-
assigned linklocal, multicast/whatever initialization is necessary.
- do not cache mac addr in the kernel. grab mac addr from existing cards
(this is important when you swap ethernet cards back and forth)
now ppp6 works just fine!
call in6_ifattach() on ATM PVC interface to assign link-local, using
hardware MAC address as seed.
(the change is in sync with kame tree).
cardbus_get_capability() [mirror change already made to if_tlp_pci.c]
- if_tlp_cardbus.c: If we don't find an ISV SROM, try to grab the
Ethernet address from the CIS.
- if_tlp_cardbus.c: set CardBus cards to store-and-forward mode from
the get-go.
- Put the TxThresh tables in tulipvar.h, and use them in the CardBus
and PCI front-ends to go to store-and-forward mode.
- Document the Xircom X3201-3 clone a little more.
delay(1000000) and retry. The 1s delay is needed for some special case only,
no need to hang the machine for that long everytime (especially for PCMCIA).
that Charles added in rev 1.58. Not only is it good programming practice
to explain magic, but code that looks like:
reg = pcic_read(h, PCIC_IDENT);
reg = pcic_read(h, PCIC_IDENT);
is _gonna_ be interpreted as a cut-n-paste error by someone eventually.
if an IRQ was not detected, unless the force flag was given. Use this to
detect if the IRQ was for us (closer to shared IRQ for controllers which
don't have their own IRQ handler in pciide.c) and to poll for DMA xfer.
Also makes the timeout recovery code simpler.
- ATAPI cleanup: don't call controller-specific functions from atapiconf.c
(wdc_*), so that it's possible to attach an atapibus to something else
than a wdc/pciide (Hi Lennart :).
Overload struct scsi_adapter with struct atapi_adapter, defined
as struct scsi_adapter + atapi-specific callbacks. scsipi_link still points
to an scsi_adapter, atapi code casts it to atapi_adapter if needed.
Move atapi_softc to atapiconf.h so that it can be used by the underlying
controller code (e.g. atapi_wdc.c).
Add an atapi-specific callback *atapi_probedev(), which probe a drive
in a controller-specific way, allocate the sc_link and fills in the
ataparams if needed. It then calls atapi_probedev() (from atapiconf.c)
to do the generic initialisations and attach the device.
- While I'm there merge and centralise the state definitions in atavar.h.
It should now be possible to use a common ata/atapi routine to set the
drive's modes (will do later).
Actually, it is partially duplicated with SIOC[GS]IFMEDIA and
SIOC[GS]80211NWID ioctls currently supported. But I'd like to leave it
until configuration interface for common 802.11 stuff will be cleaned up.
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
make them type-generic, which is necessary i.e. to operate on file offsets
without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
integral type (paddr_t, vaddr_t).
Originally done by Chuck Silvers, updated by myself.
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
- Make synchronous writes optional, disabled by default (*way* too slow).
- Handle case where dm_nsegs > CAC_SG_SIZE.
- Fix a couple of silly bugs.
- Fix use of __attribute__((__packed__));
field in the softc, instead of relying on NPCI > 0. This would
prevent things from compiling if PCI buses were in the config file,
but ahc was attached only to something else than the PCI bus.

- read out original settings to find out what the defaults (EEPROM) for this
board were, instad of hardwiring to auto.
XXX the first might need further refinement. At least on my boards, 10baseT
doesn't work for 10baseT, only AUTO.
handling. This is important when multiple cards are present when
the system boots, as we use tsleep now instead of delay in various
places (delay used to provide serialization by virtue of not causing
a context switch).
old data in pointer fields. NOTE: we'll extend m_pkthdr field soon.
Wondering: do mbuf pre-allocation code in elink3.c really buy us much
performance? it comes with code duplicate/synchronization problem with
sys/mbuf.h...
- Cosmetic changes.
- Shut down all HBAs "simultaneously", not individually.
- Don't bother grokking HA_ST_MORE. It causes problems.
- Other bits and pieces.
turning back on fast posting!). Redo fabric (re)login loop- don't try
and log out ports that haven't been logged in. Do correct target id
shuffling so we just always find the target ID we want. Add in support
for > 12 byte commands for parallel SCSI. Handle some Dual Bus reset
stuff. Finally fix ABORT COMMAND to use the right 16 bit order of the
handle to abort.
DRQ is not asserted). Closes kern/9346.
- Change the "fake identify before the real one" by a delay(). The real cause
of the problem is that the drive is unresponsive just after a reset.
The real problem (and the solution) showed up after the first change.
generateion parallel SCSI cards (1240/1080/1280/12160). Split up nvram
reading routines to be more readable. Fix topology reporting- 2200 has
connected topology in mailbox 6 when you're done getting your loop id
(supported: Private Loop (NL Port), N-Port, F-Port, FL-Port). The 2100
doens't report this, but we can synthesize it to be either NL-Port or
FL-Port. Add in some connection mode async events.
