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
only affected E1 spans since by default all spans are configured for ulaw by
default.
This fixes a regression introduced in r10290 [1] "wct4xxp: Add support for
TE820 and VPMOCT256", first released in 2.6.0, that only affects E1 spans on a
quad and dual-span card when used with the hardware echocanceler.

The DAHDI_ONHOOKTRANSFER ioctl was incorrectly setting the ohttimer to 0. The
result was that an FXS port was leaving the on-hook transfer state before
finishing the transmission.
This was discovered while looking at why ./fxstest dtmfcid was not able to
pass the DTMF callerid digits to an attached FXO port properly.
Fixes a regression introduced in r10167 "wctdm24xxp: Use interval for checking
FXS on hook transfer timer." [1], first released in 2.6.0.

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).

This restores a somewhat limited functionality of the "span"
write interface in the SysFS node of the span, broken by the
pinned-spans code.
* PROBLEM: dahdi-linux pinned-spans should work with existing dahdi-tools
specifically the dahdi_registration tool.
* As a result, we should still be able to control dahdi registration
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
messages from DBG() to NOTICE()

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()

dahdi: Add "hardware_id" dahdi_device attribute.
- The "hardware_id" does not change with device location (e.g: when a PCI
card is moved from one slot to another).
- Not all devices have this attribute. It is legal for it to be NULL (that
is the default for all low-level drivers that do not set it explicitly).
- When "hardware_id" is NULL, the sysfs attribute value is "\n"

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.

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."

A "(VPMADT032)" string is appended to the devicetype (as shown by
dahdi_scan) for the span if one is installed. Now append '(VPMOCT032)'
if one is installed as well.
Also, for the wcte12xp driver append the VPM name to the device type after
initially probing as opposed to only after the span is configured.

* 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().

all interrupts disabled and therefore it was possible to lock up a CPU with a

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.

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.

Part of increasing system startup speed.
Splitting these two operations facilitate checking if there is a module
present synchronously on driver load from the actual load of the firmware and
configuration of the channels.
This will allow the presence of the VPM module to be flagged on the span
before registration, but load and configuration can happen in the background.
When the modules are eventually loaded via udev, there will be enough time

dahdi_ec_chunk is the function that saves the received audio and places
a signed linear copy of it in the pre echocanceled buffer on the
channel. By splitting the input and output of this function into two
parameters, a driver that can provide separate pre and post ec streams
can pass them independently to DAHDI, without worrying about DAHDI
overwriting a stream that may have already been echocanceled by the
hardware.
Previously, the dahdi_ec_chunk interface took a received audio buffer
and overwrote it after canceling the echo. Now the input and output
from the function are broken up in order to support hardware echocans
that have a different preechocan stream.

Commit r9781, "wcte12xp, wctdm24xxp: Remove unused support for booting
VPMADT032 from SPI", introduced a bug that would prevent the VPMADT032
from ever being able to complete its startup. This regression did not
make it to any releases.

Introduced in rev 9905, this bug could cause buffer events to become
disabled if the kernel was unable to access userland data.
git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9907 a0bf4364-ded3-4de4-8d8a-66a801d63aff
Add BUFFEVENTS and individual buffer event channel flags so that DAHDI can
notify userspace processes when it is dropping data. This can be useful when
trouble shooting fax problems since DAHDI currently silently discards data
becasuse of scheduling latency. With this change, Asterisk could log an event
as opposed to just leaving it up to the tone detectors to figure out there was
some unexpected phase shift.

Alexandre reported that on a particular server he would get a server
crash when loading the wcte12xp driver after receiving a line about a
timeout when trying to read the mode selection jumpers.
If the driver times out when trying to read the mode selection bits
there is a serious problem and it should not try to continue on with
configuration / registration.

Most of the timers added to the kernel will be configured to fire at the

all the waiters. On one test system, I saw about a ~10% improvement in

Fixes a regression introduced in r9611. Analog spans would never become
the master since the SPANSTART ioctl is not typically called on them,
and therefore they were never marked RUNNING. The result could be audio
problems.
I'm marking this as related to issue 13205 since it's generally all
related to how should the drivers select which span is the master. I
also mark as related to issue 16165 because the problems experienced are
a result of the same fundamental issue.

Move pseudo channel numbers up into a high range so that their presence
does not interfere with assigning channel numbers for the channels
implemented on spans. Otherwise, if a pseudo channel was opened up
before an expected span was registered, all the channel numbers in the
newly registered span would be bumped up one. This does limit the number
of real channels that a single system may have registered to 32K (but in
dahdi-linux 2.4.0 and below you were limited to 1024 channels anyway,
both real and pseudo).
Also, the string name of the Pseudo channel is now based off the
number of Pseudo channels and not the total number of channels.

an existing device node for a channel, I abuse an unused flag:
DAHDI_FLAGBIT_DEVFILE (25), to mark if the channel has a sysfs node.
DAHDI_FLAGBIT_DEVFILE is expected to be replaced later on with a proper
pointer to the device (or embedding of the device). I prefer a simple

This fixes a regression from r9609 that Tzafrir reported. If you
register multiple spans, then remove the first span and try to register
a new span with more channels then the old span, you could end up with
multiple channels with the same number.
This change ensures that spans are ordered and that channels on a span
are always contiguous and ordered in relation to the spans.
In previous released versions of DAHDI (2.4.0 and below) this condition
would result in spans that may not have contiguous blocks of channels.
So it fixes both a recent regression and improves the behavior.

The default tone lengths are compile time options and they were in
digits.h to make it easy for users to patch. Most of these settings are
potentially overridden from user space via the DAHDI_SET_DIALPARAMS
ioctl currently regardless of these settings.
In r9597 I moved digits.h directly into dahdi-base.c since I thought it
was broken out for sharing between compilation units as opposed to
ease patching.
I also changed the units of the default options to ms instead of in
samples. This way if the sampling frequency changes the user will not
need to update the defaults.

Since there isn't a fixed array to hold all the channels, and also limit
the total number of channels that can be created, we'll add a module
parameter to allow the system administrator to specify the maximum
number of pseudo channels. This is to prevent a potentially
non-privledged process from consuming too much CPU (since all pseudos
are checked each "tick" for conferencing) and kernel memory.
By default the number of pseudo channels is limited to 512. Change the
default limit with:
]# modprobe dahdi max_pseudo_channels=<new limit>
or at runtime with:
]# echo <new limit> > /sys/module/dahdi/parameters/max_psuedo_channels

This change primarily is a memory reduction. Most users only ever have
a single tone zone loaded so we can save some mostly unused pointers by
using a list instead of an array. Since we also have a pointer to the
dahdi_zone in struct dahdi_chan, we also don't need to store the integer
that is an index into that array. This saves 4 bytes for every channel
allocated in the system. Finally, we don't need a separate default_zone
member since we're on a list, we can define the first element on
the list to always be the default zone.
Additionally, all reference counted structures in the drivers should
standardize on kref as much as possible for simplicity.

Normally, spans are accessed via channels, which increment the reference
count on the supporting module as part of the open call. When operating
on spans by number we are susceptible to a module_unload while we are
accessing the span.
Renames find_span to span_find_and_get to indicate that we're both
finding the span by number and increasing the reference count on the
span. Spans themselves don't currently have reference counts, but we
can increment the reference count on the module that owns the spans.
This will prevent the module that has the span from unloading in the
middle of a span_config call, which in the case of the wcte12xp can take
awhile since the VPM firmware is loading.
Hopefully in the near future the spans themselves will be reference
counted directly.

Some spans, specifically dynamic local spans, should never be the timing
master since they are dependent on some other timing source driving
them.
The bit in 'struct dahdi_span' is named cannot provide timing so that by
default the other drivers will set it to 0.
This is loosely related to issue #13205 but doesn't address any of the
other elements of that issue about how to allow the user to configure
what the master span order of succession is.

Dynamic spans that are unable to provide their own timing, like dahdi
local spans, typically derived their timing source from

This change uses the sync_tick member of dahdi_span_ops instead so that
dynamic operations do not happen on a span until it is fully registered.
Also removes the check for dahdi_dynamic_ioctl in process masterspan for

Move the try_module_get/module_put calls from the various dynamic
drivers into the "core" dahdi_dynamic.c file itself. This way, a
reference count can always be held while calling through the function
pointers. This is enabled by adding an .owner field to 'struct

Dynamic spans are also unique in dahdi in that they require a "dahdi_cfg
-s" to stop them and release the references on the modules. This is
counterintuitive. This change makes sure they are reference counted just
like other spans and on driver unload, if there aren't any open handles

dahdi/wcb4xxp driver used with Digium Wildcard B410 quad-BRI PCI card
unable to communicate with another ISDN device (ISDN phone, another port
of B410). It appears that B-channels are capable to transport data, but
D-channel is not.
Debug output added into the driver shows that packets are transmitted to
the D-channel, but no packets are received. Further investigation shows
that no interrupts received from Rx FIFO associated with D-channel,
although packets are delivered to the FIFO. I've found that problem is
in improper usage of chan->chanpos while indexing the fifo index
(bspan->fifos): chanpos starts from 1 and fifos starts from 0.
Therefore, garbage read instead of fifo number.

Instead of using pci_set_drvdata embed the 'struct voicebus_operations'
directly in the context so we can use container_of to find the context.
This resolves a problem where the 'remove_one' callback gets an invalid
pointer to 'struct t1' if the VPMADT032 is in the middle of a reload
when the module is unloading. DAHDI-783.

There are some platforms where the read-line multiple transaction causes
packets to be dropped in the voicebus pipeline. The only observable
behavior is that packets just go "missing" in the pipeline. This also
only appears to affect PCI cards.
A typical 'symptom' of this problem is you may see IRQ misses increasing
without any corresponding "bumps" in latency in the kernel message log.
Normally, IRQ misses are correlated to latency bumps since that is an
indication that the host was not able to service the card interrupt in a
timely fashion. DAHDI-510 DAHDI-774

The wcte12xp does all the checking for alarm in a user space workqueue.
Most of this time is spent sleeping waiting for reads from the framer to
complete. Tasks in uninterruptible sleeps are added to running tasks
for the purposes of calculating load average. This change makes the
sleeps interruptible so as to not affect the load average as much.
For example, the following command will load and configure the driver and
then print the load average every 10 seconds.
]# modprobe wcte12xp && dahdi_cfg && ((x=12)); while [[ $x -gt 0 ]]; do cat
/proc/loadavg; sleep 10; let x=$x-1; done

"PRI" (E1/T1) ports, the initialization script will attempt to read from
a non-existing SysFS file, and bail out, resulting in a the device
failing to initialize.
For those non-existing ports we can just skip that part of the

Work around: explicitly set pri_protocol to E1 or T1, as needed.

The bigzaplock was used to prevent changes to all the channels during
masterspan processing while conference parameters were changing. The
master span processing also took a global lock out on the chan_lock to
prevent new channels from being registered or unregistered during
processing. Instead of grabbing both those locks, just changing the
semantics of chan_lock to those of bigzaplock seems to fit the bill and
removes another lock from the driver (and saves ~10 ns on a 2.40 GHz
Xeon in prcocess_masterspan)
chan_lock is a candidate for conversion to RCU but usage in conferencing
(bigzaplock type usage) needs to be audited carefully before conversion.

When no hardware spans are configured DAHDI will use a kernel timer in order
provide timing for conferences. This is what dahdi_dummy historically was used
for. When kernel timers are used to provide timing DAHDI can both potentially
slow the rate at which time timer runs and also needs to account for how many
milliseconds of audio are processed for each 'tick' of process_masterspan.
The result is that if you are only using DAHDI for app_meetme, you can change
DAHDI_CHUNKSIZE to 40 (5ms) or 80 (10ms) bytes to reduce overhead since user
space is dealing with chunks of 20ms by default anyway.
NOTE: If you set this, you may still need to comment out the board drivers in
drivers/dahdi/Kbuild since they all do not support operating with a
DAHDI_CHUNKSIZE != 8 currently.

dahdi_receive, dahdi_transmit, and dahdi_ec_span are mostly called from
interrupt context anyway, so we can save a few cycles by not saving and
restoring the interrupt flags for every channel.
On one 2.40GHz Xeon test machine, for a span with 24 channels w/o echocan
enabled with ~10000 samples:
Function Avg Before Avg After
======================================
dahdi_receive 2.109 us 1.547 us
dahdi_transmit 3.203 us 2.766 us
dahdi_ec_span 0.416 us 0.454 us
NOTE: The time went up slightly on dahdi_ec_span since I did not have
software echocan enabled and this change calls local_irq_save regardless
in dahdi_ec_span. The slight increase in processing time in this case
is overshadowed by the savings in dahdi_receive and dahdi_transmit. If
echocan was enabled on all the channels there would be a time savings
in that dahdi_ec_span too.
When dahdi_receive/dahdi_transmit are called every millisecond (when
DAHDI_CHUNKSIZE == 8) this saves ~0.1% CPU time for each span.

The voicebus interface constantly uses the same buffers for moving data
to/from the card. A fixed pool has less overhead in this case than
constantly mapping/unmapping the kmem_cache_alloced buffers.

ports. *ALL* FXO ports will be placed in digital loopback mode when
set.
The current intent is for this to be removed as an optional module

Otherwise, a new IOCTL would have to be defined and a tool written in

If we know that an open file is associated with a channel (pseudo or

Since pseudo channels are without spans and we would like to use the
span list to enumerate through all the channels, keeping the psuedo
channels on their own list is required. I believe this is a more
natural choice than making a dummy spans for pseudos since pseudo
channels should *really* just be an implementation detail that the user
shouldn't care about.
