The VPMOCT128 module was using the VPMOCT256 timeslots assigments which would
mean that channels that should be marked alaw were being set in ulaw. This

This fixes a regression introduced in r10290 [1] "wct4xxp: Add support for

If the hook state on an FXS port changes before the channel is
configured with dahdi_cfg it is possible to erroneously force the line
feed register open without setting a timer to clear it.
The result would be a "dead" channel that cannot be cleared unless the
driver is reloaded and warning in the kernel log that "0 is an invalid
signaling state for an FXS module".
This change makes the OFF_HOOK to ON_HOOK change behave just as the
ON_HOOK to OFF_HOOK change has.

I've seen some platforms that do not properly route the interrupt from the
card to the host CPU. In these cases the card potentially could appear to be
greened up even though no data is flowing over the spans.
This change allows dahdi_cfg to return an error when this occurs, and also
ensures that all the spans are in RED alarm.
For example, dahdi_cfg output when the card is not generating interrupts:
# dahdi_cfg
DAHDI startup failed: Input/output error
And the kernel log will contain a string like:
wct4xxp 0000:02:08.0: Interrupts not detected.

Restores the pri_protocol attribute of the XPD node in SysFS to be
writable. Fixes a minor regression from the pinned-spans fix, similar to
r10334.
* This attribute was made R/O in digium r10280 as part of the
pinned-spans changes:
- The E1/T1 settings were changed via new set_spantype() method
which was called from dahdi when the 'spantype' dahdi attribute
was written to.
- This fails our init_card_4_* trying to write E1/T1 into our private
attribute.
* Restored our old code (with minor modifications) so we
can set E1/T1 the old way (writing to our 'pri_protocol' attribute)
as well as the new way (when it will be used eventually).

* PROBLEM: dahdi-linux pinned-spans should work with existing dahdi-tools
specifically the dahdi_registration tool.

order. However, registration is now in complete devices and not spans
* Restored dahdi_autoreg=[0/1] xpp module parameter:
- It now refers to complete astribanks and not individual spans
* The xpp module sysfs "span" attribute:
- Implemented write method (for dahdi_registration tool)
- The first write of [1/0] to this attribute, registers/unregisters
the complete astribank
- Further writes are ignored (with DBG messages)
* Also, implemented new xbus_is_registered() function
* Once the new dahdi-tools are merged, we should turn deprecation

For some boards, the linemode (E1/T1/J1) is software selectable but
needs to be configured before the spans were historically registered
since the line mode determines the channel count available on the span.
This change exports a "spantype" attribute from the dahdi_device that
can be used to set E1/T1/J1 before the spans are assigned. When
userspace writes to this attribute (in a <span offset>:<span type
string> format), and if the board driver has implemented a set_spantype
function in it's dahdi_span_ops, then the board driver can optionally
change it's mode before registration.
Also part of this change is breaking out the raw data structure
initialization of the spans / channels via the dahdi_init_device_spans
function since the board drivers may need to reallocate channels / spans
as part of this callback. For example, changing from T1 to E1 mode will
require allocating 7 new channels.

This exposes dahdi devices in sysfs and also exposes attributes that
will allow user space to control the registration order in spans. This
facilitates loading drivers out of order yet keeping consistent
span/channel numbering, which in turn will eventually allow the
blacklist for DAHDI drivers to be removed. The default behavior,
controlled with the auto_register module parameter on dahdi is to number
the spans / channels in order like is currently done. So this change
does not introduce any new behavior by default.
* Writing (anything) to this attribute returns the span to its
unassigned state
* Fix dahdi_chan_unreg() echocan refcount
* Add safeguard against duplicate unassignment to _dahdi_unregister_span()
* Remove the span from device_node list, only in dahdi_unregister_device()
and not in dahdi_unregister_span()
* Free allocated span->span_device in span_sysfs_remove()

Increasingly, spans are implemented by devices that support more than a
single span. Introduce a 'struct dahdi_device' object which explicitly
contains multiple spans. This will allow a cleaner representation of
spans and devices in sysfs since order of arrival will not determine the
layout of the devices. This also gives the core of dahdi a way to know
the relationship between spans.
This generalizes similar concepts that were previously xpp specific. The
conversion of the xpp code was almost entirely done by Oron and Tzafrir.

This patch contains interim results while trying to make
device removal work correctly:
* XPP has protections to prevent dahdi unregistration while
channels are open -- they are now removed, so we can
unregister immediately.
* Handle processes in poll_wait():
- Wake them during dahdi_chan_unreg() after the channel
is gone (chan->channo = -1 or chan->file->private_data == NULL)
- Test in every wait_event_interruptible() that the channel
was not gone (chan->file->private_data)
- Return correct values (POLLERR | POLLHUP) instead of
some errno (would be important in the future if we
modify asterisk to respond correctly to this condition.
* Other issues:
- If unregistered channel is being polled, than call msleep() before
returning, to give other processes a chance (normally, asterisk
has RT priority)
- Call close_channel() from dahdi_chan_unreg() so it releases
related tonezone
* There is still a horrible race hidden by msleep(20) in
dahdi_chan_unreg()
force close channels from dahdi_chan_unreg():
* Mark them via DAHDI_FLAGBIT_OPEN
* Call low-level driver close() method if available
* What about other closing activities?

The 'pedanticpci' module parameter, which is always on by default,
inserts extra reads from the card in order to ensure that all writes are
properly flushed through any PCI bridges which may post the writes. The
side effect is that this takes more CPU time for registers reads and
writes, especially to the framer registers.
It is never recommended to run with pedanticpci set to 0, so I'm
removing it as a module parameter so that the default case does not take
a performance hit checking for whether the parameter is set or not.

This function also changes the return value from bool to int for the

kernel versions include stdbool.h in the headers and it will conflict
with boolean values that are exported via module parameters on some

Commit r9750 "wct4xxp: Reduce the memory footprint of the hardware
echocanceler.", as part of reducing the non-pageable memory required to
support the VPMOCT064 and VPMOCT128, disabled caching of some hardware
echocan registers. This resulted in more physical reads to the echo
canceler. These new read transactions exposed an existing issue where
sometimes reads could be turned into writes which put a channel into an
unintended state preventing Asterisk from detecting any DTMF.
This issue is resolved by ensuring that the write signal to the Octasic
part is explicitly cleared between when the address is presented on the
bus and when the read and chip select signals are asserted. The cost is
an increase in the average time to enable / disable echo cancellation by
about 5 us on one Intel Xeon X3220 test machine (~250ns increase per
read from the Octasic part and 20 reads to enable / disable a channel).
This commit resolves a behavioral regression first introduced in 2.5.0
and 2.4.1 which could take many calls before revealing itself. This
change only affects cards with a VPMOCT128 or VPMOCT064 installed.

dahdi_maint before this change:
# dahdi_maint -s 1
Span 1:
>Framing Errors : 0:
>CRC Errors : 0:
>Code Violations : 0:
>E-bit Count : 0:
>General Errored Seconds : 0:

Span 1:
>Framing Errors : -1:
>CRC Errors : -1:
>Code Violations : -1:

There were a couple of reports that MeetMe conferences were not
working in 2.5.0.1 and that downgrading to 2.4.1.2 resolved the
issue. This could occur if there were no analog spans in a system,
and all the digital spans were out of alarm before DAHDI_STARTUP
ioctl was called by dahdi_cfg. If the spans were *not* out of alarm,
they would be marked master when the span changes it's alarm state.
This would result in a condition where no spans were marked as the
"master" and so the core timer was handling conferencing. The core
timer runs by default at 4ms and most board drivers run at 1ms
intervals, but a channel currently only buffers up 2ms of data when
conferenced. Therefore, 2ms of audio from a board was continuously
dropped from the conference every 4ms by default.
This fixes a regression first introduced in 2.5.0 which was
specifically added in revision r9611 "dahdi: Do not locate new
master in interrupt context."

* Bug sympthoms: wrong FSK VMWI sent few seconds after
offhook. That was caused because the driver kept
polling the (physically unconnected) digital inputs.
[note: a workaround for drivers without this patch
is to zero the 'xpd_fxs.poll_digital_inputs' parameter.]
* Also, the digital_inputs/digital_output masks were
calculate using a different condition.
* Now we determine number of channels, digital inputs and
digital outputs in a single place and use this info
later to calculate the correct masks.
* We poll only if there are digital_inputs
* We added a sanity check in process_digital_inputs, so
we get a notice if it's called on an xpd without digital
inputs (e.g: hypothetic firmware bug).

DAHDI currently waits a second before checking if a board driver is
calling dahdi_receive and switching to internal timing. Some versions of
Asterisk (I was looking at 1.4.42 when writing this) only wait 300ms for
a timer to expire when first starting and verifying that DAHDI is
properly configured. This can result in a
"ERROR[27673] asterisk.c: Asterisk has detected a problem with your DAHDI
configuration and will shutdown for your protection. You have options:"
message if asterisk is started soon after loading DAHDI.
This change sets the inital polling interval to the same as that used
during normal coretimer operation, 4ms. The interval will still be
slowed to 1 second if a board driver starts calling dahdi_receive().

If set to true (default) a HWEC, if available on the channel, takes
priority over any software echocan configured in /etc/dahdi/system.conf.
This has historically been the default behavior in all released versions
of DAHDI that support module echocans.
Otherwise, hwec_overrides_swec is set to false, HWEC is chosen only via
the "echocanceller=hwec" directive.

This adds module parameter 'ring_trapez'. When set, the wave form of
the ring tone is set to be a trapezoid, rather than sine. Thus making
the ring stronger.
This is a boolean parameter of the module xpd_fxs. Takes effect at the
beginning of the next ring.

In some cases the hardware echo canceller cannot be used. Mostly related to
an FXO module.
* FXO module if the first module is BRI or PRI
* FXS module if the Astribank has another FXO, no PRI/BRI, and is a sync

The dual and quad span cards have a rotary switch onboard which controls
the order that cards serviced by this driver are registered with the
core of DAHDI. This commit adds a module parameter 'ignore_rotary'
which, when set to 1, causes the driver to ignore the position of the
rotary switch and only consider the physical slot when registering with
DAHDI.
Ignoring the rotary switch settings also permits the PCI device to be
bound and unbound from the driver at runtime since registration with
DAHDI no longer only happens when the module is first initialized.
By default, the rotary switch will still be used to determine
registration order. This commit does not change the default behavior.

When true / 1 the FXO port will use a shorter off-hook calibration
delay. This is sometimes necessary in order to properly decode Type-II
Caller ID information which is sent shortly after an FXO port goes off
hook.
Defaults to 0 unless opermode is "JAPAN" then it will default to 1. This
functionality was ported from the wctdm.c driver.

If an FXS port is configured to use kewl start signalling, when the FXS port
is "hungup" it should drop battery for 500ms so that any attached devices can
detect that the remote side has disconnected. The wctdm24xxp driver
since version 2.4.0 was only dropping battery for ~5-10 ms because it would
set "open" on the line, but then the next time it read the line feed register
state, it was setting the LINE feed register to the idle state.
This change checks if the line is forced open before setting the FXS port back
"onhook" so as to not turn on battery prematurely.
This fixes a regression introduced in r9070 "wctdm24xxp: Prevent FXS Proslic
staying in "Forward/Reverse OnHookTransfer...". DAHDI-849.
Checking for open on the line feed registered was originally suggested by Alec
Davis.

In previous releases of DAHDI if dahdi_cfg attached a software echocan
to a channel and a hardware echocan was available, the hardware echocan
would be used instead of the software echocan.
Since the 2.4 branch was created a new feature was merged into
dahdi-linux where it was possible to mix software echocan and hardware
echocan on a channel. This required using "hwec" as the echocan in the
/etc/dahdi/system.conf file so that what was specified in the
configuration file is what was actually used.
This has resulted in users upgrading to the trunk of dahdi without
updating their /etc/dahdi/system.conf file and just suddenly not using
any hardware echocans any longer.
The capability to mix software and hardware echocans on a span will be
revisted when running dahdi_cfg on any preexisting configuration files
doesn't just silently turn off hardware echocan.

r9946, "wcte12xp: Move the VPMADT032 test/configuration to module load
time." introduced a race condition where it was possible for the timer
that initiates the check for the alarms to fire before the board was
marked initialized. This would result in a board that would never again
check it's alarm state since the first time the timer runs INITIALIZED
may not be set and it will not reschedule a check since it believes the
driver is unloading.
This happened because the check for the VPM was moved between when the
timer was first setup and when INITIALIZED was then set.
Now we make sure INITIALIZED is set before the timer is first setup, and
move those two operations together.

In commit r9968 "wctdm24xxp: Allow more than one outstanding read at a
time" I introduced a regression where the transmit FIFO on the data
channel of a B400M could get locked up. The result would be constant
HDLC overflows when writing to the data channel.
This regression did not make it into any releases and did not exhibit
itself when crossing spans on a single B400M module. This is a partial
revert of commit r9968.
