rev. 10502 of the FPGA firmware for the new E-Main rev. 4 fixes a potential
issue when used on Xorcom XR1000 systems: an issue with the power supply may
cause the unit to reset.
Note that there is no issue with previous models, with a normal setup of an
Astribank, or other XRx000 systems.

It appears that some kernel configurations do not include timer.h in any of
the include files that are included by dahdi_dummy. The timer_structs are
defined in timer.h and not time.h, so this change is correct even though I
never could find a configuation myself that actually failed to compile.
This has negligible impact since dahdi_dummy is not compiled by default.

Minor change to follow generally recommended practice. Prevents new packets
from being queued up for devices when they are about to be cleaned up. Also
clean up any skbs that may still be on the queue after unloading.
Also closes anoter potential kernel oops on module unload. It was possible to
delete the private structure while the master span process was running. The
result was an attempt to page memory from interrupt context.
Make sure that the pvt function is set and cleared under the zlock. Also do
not assume that the pvt pointer is valid in ztdeth_transmit.

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().

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.

- I.e: vbat_h follows the ring-up/ring-down.

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.

This is needed in order for the Dahdi perl classes (in tools) to get
the inforamtion for e.g. dahdi_genconf to work without the guesswork of
parsing /proc/dahdi .

The dahdi_echocan_* modules had an unused debug_printk() macro. Remove
them because:
* They were unused
* There were multiple definitions
* They were unsafe. Someone doing an
if(foo)
debug_printk(...);
else
do_something();
may be surprised ;-)
* They used 'debug' as a debug level, while the rest of DAHDI debug
macros treat it as a bit-field.
Leave only a single definition in wcte12xp/base.c which is safe.

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.

can set E1/T1 the old way (writing to our 'pri_protocol' attribute)

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:

* 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

- Relaxed the timeout waiting for OCT6114 bus cycle completion to 100 mS
and added a 2 mS delay time from OCT6114 reset to initialization.
This change only addresses issues that were created in the lab and not in the
field.

This commit adds field upgradeable support for the TE820 firmware.
Firmware can now be silently upgraded as part of updating drivers
like most of the existing DAHDI firmware. Previous versions of dual
and quad span cards did not support upgrading firmware in the field.

- qevent DAHDI_EVENT_REMOVED
* Use disable_span():
- in dahdi_unassign_span() and dahdi_unregister_device()
- with long msleep() so asterisk has a chance to get the message
- Out of the registration_mutex so we actually context switch.
* Also return more POLLERR variants (POLLRDHUP is not portable,

* Reparent astribanks below their USB transport
* This way their location can be derived from their hardware
hierarchy.
* The tradeoff is that once USB hardware is disconnected, there
is no sysfs visibility of the astribank object even if it
cannot be release yet due to open channels by asterisk
* Thus, we'll need to migrate to "surprise removal" of dahdi
devices...

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.
