1) Non-AST4 multiport cards were broken by bypassing the code that changes
`idev' to the multiport master device.
2) AST4 multiport cards apparently were broken by inverting the test for
the master device having an irq.
3) Error handling for nonexistent master devices was broken by removing a
check for a null pointer.
4) `int' error codes returned by bus_get_resource() were assigned directly
to the boolean variable com->no_irq. Probably harmless, since the
boolean is implemented as a u_char.

- Remove all the code intended to deal with experimental
C1010 revisions. This code got useless due to commercial
chip revisions having been fixed.
Fixes:
- Rewrite/rework the WSR condition handling.
Previous drivers snooped on the BUS through the SBDL IO
register and this has been discovered to trigger a spurious
SCSI parity error when WSR had been set by chip and cleared
by SCRIPTS prior to reading SBDL bit [0...7].
On the other hand, the C1010 does not use the SWIDE register
when synchronous data transfers are taking place and
requires a CHMOV (1) WHEN DATA_IN to be performed in order
to move to memory the residual byte when WSR is set and
the residual byte is useful data.
BTW, the new WSR handling by the driver is simpler.
- No longer attempt to read from SCRIPTS the SBDL register.
This is intended to avoid to be victimized again by any other
issue regarding the handling of this register by 8xx chips.
Miscellaneous:
- The driver is now able to handle the WSR + IGN RESIDUE
condition at the end of a DATA IN I/O without need of a
programmed interrupt. It is a minor? optimization.
- A few other minor cosmetic changes.
This driver version fixes notably a permanent SCSI parity
error condition at boot that can be triggerred due to recent
changes in cam_xpt.c between 1.79 and 1.80.
Changes in CAM/XPT are fine, but the new handling of the full
INQUIRY may trigger the driver problem when a target returned
an odd value in the `additionnal length' field of the INQUIRY
response.
The diff against previous driver version is large, but it
consists approximatively in:
- 350 lignes removed and not compiled in previous drivers
(They addressed experimental C1010 revisions)
- 250 lignes added or changed, half being comments or empty
lines.
So, in fact, the real changes are about 120 lines of source.
About 80 lines address SCRIPTS changes and about 40 lines
address C code changes.

Reduce the number of transfer negotiations that occur. In the past, we
renegotiated after every reported check condition status. This ensures
that we catch devices that have unexpectidly reset. In this situation,
the target will always report the check condition before performing a
data-phase. The new behavior is to renegotiate for any check-condition where
the residual matches the orginal data-length of the command (including
0 length transffers). This avoids renegotiations during things like
variable tape block reads, where the check condition is reported only
to indicate the residual of the read.
Revamp the parity error detection logic. We now properly report and

- Sync ohci, uhci and usbdi modules with NetBSD in order to obtain the
following improvements:
o New USBD_NO_TSLEEP flag can be used in place of UQ_NO_TSLEEP
quirk. This allows drivers to specify busy waiting only for
certain transfers (namely control transfers for reading/writing
registers and stuff).
o New USBD_FORCE_SHORT_XFER flag can be used to deal with
devices like the ADMtek Pegasus that sense the end of bulk OUT
transfers in a special way (if a transfer is exactly a multiple
of 64 bytes in size, you need to send an extra empty packet
to terminate the transfer).
o usbd_open_pipe_intr() now accepts an interval argument which
can be used to change the rate at which the interrupt callback
routine is invoked. Specifying USBD_DEFAULT_INTERVAL uses the
value specified in the device's config data, but drivers can
override it if needed.
- Change if_aue to use USBD_FORCE_SHORT_XFER for packet transmissions.
- Change if_aue, if_kue and if_cue to use USBD_NO_TSLEEP for all
control transfers. We no longer force the non-tsleep hack for
bulk transfers since these are done asynchronously anyway.
- Removed quirk entry fiddling from if_aue and if_kue since we don't
need it anymore now that we have the USBD_NO_TSLEEP flag.
- Tweak ulpt, uhid, ums and ukbd drivers to use the new arg to
usbd_open_pipe_intr().
- Add a flag to the softc struct in the ethernet drivers to indicate
when a device has been detached, and use this flag to perform
tests to prevent the drivers from trying to do control transfers
if this is the case. This is necessary because calling if_detach()
with INET6 enabled will eventually result in a call to the driver's
ioctl() routine to delete the multicast groups on the interface,
which will result in attempts to perform control transfers. (It's
possible this also happens even without INET6 support enabled.) This
is pointless since we know that if the detach method has been called,
the hardware has been unplugged.
- Changed watchdog timeout routines to just call the driver init routines
to initialize the device states without trying to close and re-open the
pipes. This is partly because we don't want to frob things at interrupt
context, but also because this doesn't seem to work right and I don't
want to panic the system just because a USB device may have stopped
responding.
- Fix aue_rxeof() to be a little smarter about detecting when a double
transfer is needed. Unfortunately, the design of the chip makes it hard
to get this exactly right. Hopefully, this will go away once either
Nick or Lennart finds the bug in the uhci driver that makes this ugly
hack necessary.
- Also sync usbdevs with NetBSD.
This is just to make sure we initialize the chip correctly: we need to
make the sure the port select bit in CSR6 is set properly so that we
use the internal PHY for 10/100 support. (The eval boards I have also
include an external HomePNA PHY, but I need to play with that more
before I can support it.)
- The busy wait hack in usbdi.c was doing its timeout in microseconds
instead of milliseconds.

Fix a long standing bug in the error recovery strategy. In order
to keep recovery simple, we freeze the SIMQ, stopping the XPT from

SIMQ if bus_dmamap_load blocks or we run out of controller resources.
On cards with limited resources it was possible to freeze the
SIM a second time and never unfreeze it. Now we more carefully
track our exception state so we never freeze the SIMQ more than
once.
Don't rely on pointers fitting in a 32bit field stored in the
per-transaction data structures on the card. Use an index to
an array of transaction mapping structures instead. This should
allow this driver to work on the Alpha.
Deal with the ASC3030 which is almost idistinguishable from the
ASC3050. Unfortunately the ASC3030 does not work at Ultra speeds,
so if we can't find an eeprom, we must assume that ultra is disabled.
The SIIG cards using the 3030 do not have eeproms. As a side effect,
we now honor the ultra disable bit in the eeprom if it is present.
Don't bother attempting to write corrected eeprom data back to the

Note that the CATC chip supports a nifty feature: read and write combining.
This allows multiple ethernet packets to be transfered in a single USB
bulk in/out transaction. However I'm again having trouble with large
bulk in transfers like I did with the ADMtek chip, which leads me to
believe that our USB stack needs some work before we can really make

Note1: the correct interrupt level is invoked correctly for each driver.
For this purpose, drivers request the bus before being able to
call BUS_SETUP_INTR and BUS_TEARDOWN_INTR call is forced by the ppbus
core when drivers release it. Thus, when BUS_SETUP_INTR is called
at ppbus driver level, ppbus checks that the caller owns the
bus and stores the interrupt handler cookie (in order to unregister
it later).

chip appears to silently corrupt or discard transmitted frames when
using scatter/gather DMA (i.e. DMAing each packet fragment in place
with a separate descriptor). The only way to insure reliable transmission
is to coalesce transmitted packets into a single cluster buffer. (There
may also be an alignment constraint here, but mbuf cluster buffers are
naturally aligned on 2K boundaries, which seems to be good enough.)
The DM9102 driver for Linux written by Davicom also uses this workaround.
Unfortunately, the Davicom datasheet has no errata section describing

Packets are received inside USB bulk transfer callbacks, which run at
splusb() (actually splbio()). The packet input queues are meant to be
manipulated at splimp(). However the locking apparently breaks down under
certain circumstances and the input queues can get trampled.
There's a similar problem with if_ppp, which is driven by hardware/tty
interrupts from the serial driver, but which must also manipulate the
packet input queues at splimp(). The fix there is to use a netisr, and
that's the fix I used here. (I can hear you groaning back there. Hush up.)
The usb_ethersubr module maintains a single queue of its own. When a
packet is received in the USB callback routine, it's placed on this
queue with usb_ether_input(). This routine also schedules a soft net
interrupt with schednetisr(). The ISR routine then runs later, at
splnet, outside of the USB callback/interrupt context, and passes the
packet to ether_input(), hopefully in a safe manner.
The reason this is implemented as a separate module is that there are
a limited number of NETISRs that we can use, and snarfing one up for
each driver that needs it is wasteful (there will be three once I get
the CATC driver done). It also reduces code duplication to a certain
small extent. Unfortunately, it also needs to be linked in with the
usb.ko module in order for the USB ethernet drivers to share it.
Also removed some uneeded includes from if_aue.c and if_kue.c

Driver is not functional yet, but does compile. Tests with xe cards
indicates that it doesn't panic the machine when they are present, but
fail to probe. Interface help in the pcic/pccard layers are needed to
complete this driver.
o ifdef out pccardchip.h (almost all of it, there are dangling bits
o Add rid/res members to pccard_function
o remove pct/pch from pccard_softc
o map memory properly in scan_cis (almost, see XXX for more work)
o manage ccr.
o remove bogus comment I added about touching the ccr being a layering
violation for pccard. It is properly done at that level.
o More function prototyping
whilst we are playing or recording. since we should irq ~20 times/sec when
active, this should never trigger. in theory. if it never does trigger,
the check will be removed.
- Set MAX_OFFS driver compile option to 63 (was 64 which is wrong).
- Fix a typo in the SYMBIOS NVRAM layout structure and add field and
bit definition for the support of PIM_NOBUSRESET.
- Report to XPT PIM_NOBUSRESET and PIM_SCANHILO if set by user in NVRAM.
- Negotiate SYNC immediately after WIDE response from the target as
suggested by Justin Gibbs.
- Remove some misleading comment about CmdQue handling by CAM.
- Apply correctly the MAX_WIDE and MAX_OFFS driver options.
It seems that the IDE system uses 0x3f6 for itself, which conflicts with
fdc's default 0x3f0-3f7 allocation range. Sigh. Work around this.
Use bus_set_resource() rather than allocating specific areas, it makes
the code a little cleaner.

Note: the .INF file for LinkSys's driver says the vendor ID is 0x66b,
however this does not agree with the vendor ID listed for LinkSys in
the company list from www.usb.org. In fact, 0x66b doesn't seem to appear
in the company list at all. Furthermore, this same vendor ID crops
up in some of the D-Link .INF files. Frankly I don't know what the heck
is going on here, but I need to add 0x66b to usbdevs and call it
something, so here we are.
certain PHY addresses in aue_miibus_readreg(). Not all adapters based
on the Pegasus chip may have their PHYs wired for the same MII bus
addresses: the logic that I used for my ADMtek eval board might not
apply to other adapters, so make sure to only use it if this is really
an ADMtek eval board (check the vendor/device ID).
This will hopefully make the LinkSys USB100TX adapter work correctly.

Turn on scb and internal data-path parity checking for all pci chips types.
We were only doing this for ultra2 chips.
After clearing the parity interrupt status, clear the BRKADRINT. This

93cx6.c:
Make the SRAM dump output a little prettier.
aic7xxx.c:
Store all SG entries into our SG array in kernel space.
This makes data-overrun and other error reporting more
useful as we can dump all SG entries. In the past,
we only stored the SG entries that the sequencer might
need to access, which meant we skipped the first element
that is embedded into the SCB.
Add a table of chip strings and replace ugly switch
statements with table lookups.
Add a table with bus phase strings and message reponses
to parity errors in those phases. Use the table to
pretty print bus phase messages as well as collapse
another switch statement.
Fix a bug in target mode that could cause us to unpause
the sequencer early in bus reset processing.
Add the 80MHz/DT mode into our syncrate table. This
rate is not yet used or enabled.
Correct some comments, clean up some code...
aic7xxx.h:
Add U160 controller feature information.
Add some more bit fields for various SEEPROM formats.
aic7xxx.reg:
Add U160 register and register bit definitions.
aic7xxx.seq:
Make phasemis state tracking more straight forward. This
avoids the consumption of SINDEX which is a very useful register.
For the U160 chips, you must use the 'mov' instruction to
update DFCNTRL. Using 'or' to set the PRELOADED bit is
completely ineffective.
At the end of the command phase, wair for our ACK signal
to de-assert before disabling the SCSI dma engine. For
slow devices, this avoids clearing the ACK before the
other end has had a chance to see it and lower REQ.
controllers will run at U2 speeds until I can complete the U160 support
for this driver.
Correct a termination buglet for the 2940UW-Pro.
Be more paranoid in how we probe and enable external ram, fast external
ram timing and external ram parity checking. We should now work on
20ns and 8bit SRAM parts.
Perform initial setup for the DT feature on cards that support it.
Factorize and clean up code. Use tables where it makes sense, etc.
Add some delays in dealing with the board control logic. I've never
seen this code fail, but with the ever increasing speed of processors,
its better to insert deterministic delays just to be safe. This stuff
is only touched during probe and attach, so the extra delay is of no
concern.
ethernet adapters that are supported by the aue and kue drivers.
There are actually a couple more out there from Accton, Asante and
EXP Computer, however I was not able to find any Windows device
drivers for these on their servers, and hence could not harvest
their vendor/device ID info. If somebody has one of these things
and can look in the .inf file that comes with the Windows driver,
I'd appreciate knowing what it says for 'VID' and 'PID.'
Additional adapters include: the D-Link DSB-650 and DSB-650TX, the
SMC 2102USB, 2104USB and 2202USB, the ATen UC10T, and the Netgear EA101.
These are all mentioned in the man pages, relnotes and LINT.
Also correct the date in the kue(4) man page. I wrote this thing
on Jan, 4 2000, not 1999.

o Added DEVPRINTF which is like DPRINTF only calls device_printf.
o Made it possible to define PCICDEBUG
o Remove ph_parent and use the softc pointer sc instead in pcic_handle.
o Remove all references to dv_xname
o Add some debug messages.
o enable MI attach/detach calling for pccard.
o convert pcic_chip_socket_{en,dis}able to pcic_{dis,en}able_socket
and connect them to the power_{enable,disbale}_socket.
o Remove pccard pointer from pcic_softc.
o GC some unused pccard functions.
o Convert pccard_chip_socket* to POWER_ENABLE_SOCKET
o kill pccard_attach_args.
o power_if.m updates. More to come.
o Rename FDC_PCMCIA to FDC_NODMA to allow systems that don't have dma
for floppies.
o Remove all but two FDC_YE ifdefs. They aren't needed.
o Move defines for YE_DATAPORT to fdreg.h.
Not fixed:
o The pccard probe/attach. However, motivated individuals can more
easily add this now.
This is a merge of changes I've had in my tree for a long time. These
fixes were tested on my VAIO with its normal floppy. Please let me
know if I broke anything.

This is the hack that compensates for when bios vendors "forget" to
include the fdc control (0x3f7) port in their io port mappings. Instead
of accessing ports outside of a range allocated to a handle, simply
allocate the port directly. It even shows up in the probe..
machine but leave your KLSI adapter plugged into your USB port, it
may stay powered on and retain its firmware in memory. Trying to load
the firmware again in this case will wedge the chip. Try to detect this
in the kue_load_fw() routine and bail if the firmware is already
loaded and running.
Also, in the probe/match routine, force the revision code to the
hardware default and force a rescan of the quirk database. This is
necessary because the adapter will return a different revision code
if the firmware has been loaded. Without the firmware, the revision
code is 0x002. With the firmware, the revision code is 0x202. This
confuses the quirk mechanism, which won't match a quirk to a device
unless the revision code agrees with the quirk table entry.
This makes probe/attach of these devices somewhat more reliable.
Also add a few comments about the device's operation.
In particular:
- Don't leave resources allocated in the probe routine. Allocate them
during probe and release them. Probe's job is to identify devices only.
- Don't abuse the ivars pointer.. (!). Create real ivars and use the
proper access system. (the bus_read_ivar method)
- Don't add the children until attach() has successfully grabbed the
hardware, otherwise there are potential leaks if attach fails.
