On SMP systems there isn't a need for all dahdi timers to
synchronize on dahdi_timer_lock. Instead give each timer it's own
lock to synchronize with process_timers and use dahdi_timer_lock to
protect the global list of locks.
Also, the dahdi_timers list now only contains timers that are set to
fire. This eliminates a test for each timer in the hot path of the
process_masterspan context.
Reduces system load on many-core systems which are heavy users of
DAHDI timers.

There was a code patch where it was possible to get stuck in RED ALARM on a
channel when debouncing the battery states. The state transitions would look
like this:
BATTERY_PRESENT -> BATTERY_DEBOUNCING_LOST -> BATTERY_DEBOUNCING_LOST_ALARM --
(send alarm up to asterisk) --> BATTERY_LOST -> BATTERY_DEBOUNCING_PRESENT ->
BATTERY_DEBOUNCING_PRESENT_ALARM -> BATTERY_DEBOUNCING_LOST -> BATTERY_PRESENT
In the above sequence there was never any transition from
BATTERY_DEBOUNCING_PRESENT_ALARM to BATTERY_PRESENT so the alarm to Asterisk was
never cleared and the channel stayed stuck.
Now when you loose battery when in the BATTERY_DEBOUNCING_PRESENT_ALARM go all
the way back to the BATTERY_LOST state instead of the BATTERY_DEBOUNCING_LOST
state so that all the events are properly sent up.
This fixes a regression introduced in 2.6.0 with commit (r10169 "wctdm24xxp: Use
interval for debouncing FXO battery." 874b76bd22).

This resolves an issue with a Glenayre GL3000 Paging Terminal with v8.000
software. The Glenayre would change both A and B bits to signal on/off hook
states, but there were a couple of milliseconds between when those bits changed.
This resulted in DAHDI generating an on-hook event to Asterisk before generating
the off-hook event and therefore Asterisk terminated the call prematurely.
Looking the A and B bits before this patch:
Asterisk (AB) Glenayre (AB)
00 00 Both sides on-hook
11 00 Asterisk goes off hook to sieze line.
11 01 Glenayre starts going-offhook. On-hook event
sent to Asterisk from drivers since bits
changed but ABIT was still 0.
11 11 Glenayre finishes going off-hook. Off-hook
event sent to Asterisk since ABIT changed
from 0 to 1.
00 11 Asterisk, processes on-hook event and goes
on-hook itself to release line.
00 00 Glenayre releases line. Call fails.
After this patch:
Asterisk (AB) Glenayre (AB)
00 00 Both sides on-hook
11 00 Asterisk initiates call
11 01 Glenayre starts handling call. No event is
sent to Asterisk since only ABIT is checked.
11 11 Glanayre finishes going off-hook. Call
proceeds normally.

Internally in DAHDI there is always a hardware echocan factory registered and
available. Having this factory always registered allows for DAHDI to work in a
backward compatible fashion. Namely, by default DAHDI will always use a hardware
echocan if one is available unless 'hwec_overrides_swec' dahdi module parameter
is set to 0 on load. However, if there were no real hardware echocans available
in the system dahdi would still report "Echo Canceller(s): HWEC" in the
dahdi_cfg -v output since the hwec factory is always there.
After this change dahdi_cfg will no longer report HWEC as one of the available
echocans if there isn't a physical span present that actually has a hardware
echocan.

This fixes a regression introduced in commit r10186 "wctdm24xxp: Use time
interval for debouncing FXO ring detect." [1] which was first released in
DAHDI-Linux 2.6.0. This only affects users with analog trunks whose providers do
not present 4 polarity reversals on the ring signals. The reporter of this issue
is based in South Africa.
[1] http://svnview.digium.com/svn/dahdi?view=revision&revision=10168
In prior versions, the ring detector did not check for polarity reversals, only
the presence of ringing voltage unless fwringdetect or neonmwi_monitor mode was
set, and even when one of those modes were set, the driver only needed two
reversals to validate a ring. This commit allows the driver to always stay in
fwringdetect mode but restores the requirement for only two reversals.
Also included in this commit is a change to ensure that ringing is not reported
when debouncing lost battery which can happen when voltage is swinging through
0.

This is a port of the functionality in the wctdm24xxp driver to support power

the span to save power, the B410P previously automatically activated it again.
Now, if persistentlayer1=0 module parameter is set, the span will be allowed to
stay deactivated until layer two has a message to send on the dchannel.
This patch does not change any of the default behavior of the B410P driver and
the defaults for the persistentlayer1 option is inconsistent with that of the

The board drivers are the ones calling the unregister function, and
therefore we do not need to worry about them unloading while calling the
destroy callback.
When destroying spans with the ioctl, replace __module_get() with
try_module_get. This avoids hitting a BUG in module_get on kernel versions <
2.6.29.
ALSO move the call to try_module_get out of the dahdi_dynamic_release function
and into destroy. This way if the destroy callback isn't called because the
dynamic driver is unloading the dynamic device can be left on the list to be
cleaned up by the dahdi_dynamic_unregister_driver function().

dahdi.ko can bump up the reference count on dahdi_dynamic.ko before calling

- I.e: vbat_h is held throughout the ringing period (during
both ring-up/ring-down)
- So this patch revert part of r10478
* When switched to true, activate the "power-down" behaviour.
- I.e: vbat_h follows the ring-up/ring-down.
- This behaviour lowers the noise caused by group ringing of

This in conjunction with r10449 "A parent-less device should not crash dahdi",
this allows dahdi_dynamic spans to work post the dahdi_devices changes in
2.6.0.
The full address of the device is not used since kernels prior to 2.6.31 limit
the length of a devicename to 20 characters. The full address of the device
can be pulled out of the "hardware_id" and "type" fields of the span.
This patch is just to get things working again. dahdi_dynamic devices *may*
still have issues if the auto_assign_spans module parameter is 0.

This is a partial revert of r10234 "wct4xxp: __t4_framer_in and
__t4_framer_out speedups."
There were some platform + firmware version combinations that would fail to
properly configure the framer with the aforementioned speedups. The originally
reported sympton was that interrupts would fail to start and while
troubleshooting I also saw cases where one of the spans would stay in alarm
after starting. By adding in additional reads to the version register, the
overall process of writing / reading from the framer control registers is
slowed down which increases reliability.
This change does *not* affect the main path of TDM data which is DMAed
directly into buffers in host memory and are not read / written to / from
framer registers directly.

DAHDI internal timing currently uses the "wall clock" to determine how much
time is passing for mixing and timers. When the wall time changes, like when
the system time is set via ntp or date, DAHDI currently will display a
"Detected time shift" message since it believes there is too much audio to
mix. There may also be audio problems if the wall time is shifting
occasionally due to slewing of the clock.
Now use a monotonic clock to determine how much real-time has passed for
timing purposes. This makes DAHDI insensitive to any changes in the wall time
on the system.
This only applies when using DAHDI's internal timer like when there are not
any telphony cards installed. There are still potential audio problems if the
platform is unable to accurately determine the passage of time.

In commit r10168 "wctdm24xxp: Use time interval for debouncing FXO ring
detect" [1], I inadvertently changed the debounce interval of the RINGOFF
event from 128ms to 512ms. The result was a potential failure to detect CID,
depending on line conditions, since Asterisk would bump the rx gains on the
channel in the middle of the CID spill as opposed to before the CID spill.
This fixes a regression first introduced in DAHDI-Linux 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.

* The zero lenth case (Magic request) was split into
send_magic_request() function. It was not possible
to move it into card_bri.c, because it is called
directly from the general interface we provide for
register read/write via sysfs/proc.
* The normal case (send_multibyte_request) was moved from
card_global.c into card_bri.c
* This sets the stage to enable bundling of multibyte
packets into frames (like we do for PCM).

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:

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()

Since "wctdm24xxp: Probe for and configure modules in parallel." the
check for the VPMADT032 module was moved closer to after when the

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()

- The "hardware_id" does not change with device location (e.g: when a PCI

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.

Instead of checking all spans every millisecond when they are in

Uses the linecompat member to determine what type of span it is. This will
allow removing T1/E1 flags from other places where the span type is stored.
This function also changes the return value from bool to int for the
inlines defined in include/dahdi/kernel.h. This is because not all
kernel versions include stdbool.h in the headers and it will conflict
with boolean values that are exported via module parameters on some
older kernels if dahdi included it globally.

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."

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().

Use the newly create bg_create and bg_join to actually probe / configure
groups of 4 modules in parallel. This currently has to be done in groups
of four due to the way 4-port modules are identified relative to single
port modules.
This provides a dramatic improvement in driver load time. When loading a
single TDM2400 with 24 FXS ports before this change:
# time modprobe wctdm24xxp vpmsupport=0
real 0m46.674s
user 0m0.000s
sys 0m0.520s
And after this change:
# time modprobe wctdm24xxp vpmsupport=0

Note that the boards themselves are still configured serially. Board
configuration can be parallelized once the assignment of board position
is moved out of the function that is run in parallel. Otherwise it could
be possible for board numbers to switch on repeated loads.

Revision 9886, "wcte12xp: Use the in-hardirq versions of
dahdi_receive/dahdi_transmit", changed the call into dahdi_receive and
dahdi_transmit to use versions that assume local interrupts are already
disabled. Not all versions of the kernel run interrupt service routines with
all interrupts disabled and therefore it was possible to lock up a CPU with a
recursive grab of the chan_lock.
When LOCKDEP was enabled (on debug kernels) interrupt handlers were run
atomically so this problem would only occur on pre 2.6.35 kernels that did not
have lockdep enabled.

Revision 9750 "wct4xxp: Reduce the memory footprint of the hardware

members. Some of the new field lengths were unable to store all the
possible values the API as used assigned to the fields, resulting in
channels never entering power down mode when they were disabled like
they were previously.
The change for byEchoOperationMode was found in testing the operation of
the VPMOCT032 which currently uses the same code. The others were done
via a review of the API doc.
This change represents negligable risk and contains no logic changes.
It only increases the memory footprint of the API instance in the

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.

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

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
from the time the drivers are loaded to when dahdi_cfg will run to complete
the firmware load, eliminating the need to block the driver here.

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.
