2011-04-15dahdi: Do not save the irq information.Shaun Ruffell
If the user needs this information, there are better ways to get it than having it embedded in the device / span structures. Signed-off-by: Shaun Ruffell <sruffell@digium.com>
2011-04-15dahdi: Move irq/irqmisses from dahdi_span into dahdi_device.Shaun Ruffell
These fields do not have anything to do with the span. Signed-off-by: Shaun Ruffell <sruffell@digium.com>
2011-04-15dahdi: register/unregister devices as opposed to individual spans.Shaun Ruffell
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 also 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. Signed-off-by: Shaun Ruffell <sruffell@digium.com>
2011-04-14wcte12xp: If we cannot read the mode selection pins fail the module load.Shaun Ruffell
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.

Allow name of EC factory to vary based on channel Changed the echocan factory name to a function (get_name) called to get the name. This allows a factory to return a different name when being called in reference to a channel such as in the case of hardware echo cancellers. To further accommodate this change for HWEC, a new echocan_name function was added to the span ops struct and is used in hwec_factory in dahdi-base for all cards that support hardware echo cancellation.

2010-12-08wcte12xp: Use interruptible waits to decrease impact on load average.Shaun Ruffell
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 With this change: 0.29 0.10 0.02 1/101 29945 0.24 0.10 0.02 1/101 29967 0.20 0.09 0.02 1/101 30019 0.17 0.09 0.02 1/101 30041 0.15 0.09 0.02 1/101 30062 0.12 0.08 0.02 1/101 30085 0.10 0.08 0.02 1/101 30107 0.09 0.08 0.02 1/101 30129 0.07 0.08 0.02 1/101 30151 0.14 0.09 0.02 1/101 30173 0.12 0.09 0.02 1/101 30195 0.10 0.08 0.02 1/101 30217 (and I've seen it get down to 0.0) Before this change: 0.57 0.22 0.07 1/101 31920 0.48 0.21 0.07 1/101 31942 0.48 0.22 0.07 1/101 31964 0.48 0.23 0.08 1/101 31986 0.41 0.22 0.07 1/101 32008 0.42 0.23 0.08 1/101 32030 0.43 0.24 0.08 1/101 32054 0.45 0.25 0.09 1/101 32076 0.45 0.25 0.09 1/101 32098 0.46 0.26 0.10 1/101 32120 0.47 0.27 0.10 1/101 32172 0.39 0.26 0.10 1/101 32194 (closes issue #18142) Reported by: foxfire Tested by: foxfire Signed-off-by: Shaun Ruffell <sruffell@digium.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9512 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-08-17wcte12xp, wctdm24xxp: Add compile time option CONFIG_VOICEBUS_ECREFERENCE.Shaun Ruffell
Add compile time option to improve the reference signal provided to software echo cancelers. The intent here is for this functionality to become the default behavior but more testing and work on the edge cases is needed. It's being brought in now as a compile time option since there have been reports that it helps in some environments. Instead of using two buffers, which means that at best we're two milliseconds behind, use a circular buffer where audio data is written on the transmit side and read on the receive path. In this way high latency values will not interfere with the operation of software echo cancelers. DAHDI-291. DAHDI-387.

Removed a change to dahdi-base from last patch which might have caused compatibility with drivers other than the wcte12xp. wcte12xp: The channel clear/rbs function no longer reads the register first. It now uses the span's channel flags to determine each channels clear state. Also added various minor readability improvements. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8569 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-04-23dahdi-base: wcte12xp: Fixed Clear/RBS channel mode issueRuss Meyerriecks
Fixes DAHDI-449 where chanconfig was failing on the first call. It needed to be called twice in a row. This was due to the channel configuration using a non-relative channel number in its loop. Also re-added the register dumping ioctl for inspecting the framer's state. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8564 a0bf4364-ded3-4de4-8d8a-66a801d63aff
