Instead of registering a function pointer, register a dahdi_dynamic_ops
structure that contains the owner as well as the ioctl callback. This way
dahdi.ko can bump up the reference count on dahdi_dynamic.ko before calling
the ioctl callback.
Also, use the registration mutex to guard against the module being unloaded
between the time the structure pointer was checked, and the module reference
is taken.

The driver makes the assumption that interrupts are disabled but this cannot
be guaranteed. We'll explicity disable interrupts on the local processor while
the interrupt handler is running.

* Makes the "power-down" behaviour that was added
in upstream svn r10478, switchable in runtime.
* By default (false), makes the vbat_h behave like it did

- 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
FXS channels in the same unit, but causes problems with CallerID.

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.

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:

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

* 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

Allowing the linemode to be configured with sysfs before the spans are
assigned opens the eventualy capability for line mode to be configured
with the other physical layer settings per card. Currently linemode is
set with either physical jumpers or with a module parameter to the
wct4xxp driver that is global for all cards.
Default behavior is not changed with this commit.

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?

I only generally test on RHEL 4 when testing against kernels older
than 2.6.18. Apparently OpenSUSE 10.1 runs with 2.6.16 and doesn't
have WARN_ON_ONCE backported. I took the patch Richard Miller
originally attached to the issue and moved it to
include/dahdi/kernel.h so it would be available for all the board
drivers in the future.

Allows the globalconfig member to be removed from the struct t4 and not

There are read/modify/write operations on the framer that were not
protected by any locks. While I didn't notice any code paths that would
result in simultaneous accesses to these registers, this change will
hopefully save someone else some time in the future verifying that the
accesses are safe. A side effect is that the reglock is acquired only
once for each read/modify/write cycle as opposed to twice previously.

All those checks for wc->t1e1 span appear to basically be there to
determine if there are *any* E1 spans exported by the card. We can make
