2009-11-09wcte12xp: use the dev_xxx macro for the debounce messages.Shaun Ruffell
We want to know which device is reporting the debounce when there are more than one card in the system. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@7536 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2009-11-07voicebus: Add optional sysfs entry for reading a boards current latency.Shaun Ruffell
This is off by default since it hasn't been tested on a full range of kernels, but can be useful for quickly seeing differences for latencies on different cards installed in the system. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@7522 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-11-07voicebus, wctdm24xxp, wcte12xp: Move a print out of the interrupt handler.Shaun Ruffell
This can be handled just as well in process context and printing to a serial console from the interrupt handler has the potential to cause long latencies. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@7521 a0bf4364-ded3-4de4-8d8a-66a801d63aff

Debounce yellow alarm also. In wcte12xp, change check alarm frequency to 100ms for better debounce granularity. Fix lines over 80 cols from last alarm debounce commit. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@7486 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2009-08-19Ensure that dahdi_scan correctly reports VPM presence.Kevin P. Fleming
The wct4xxp driver (for the dual/quad span T1/E1 cards) and the wcte12xp driver (for the single span VoiceBus-based T1/E1 cards) did not properly update the 'devicetype' field reported by dahdi_scan when a VPM was found during the card startup process. As a result, dahdi_scan did not show that a VPM was present on the card, even if it was. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@7038 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-08-04wcte12xp: Remove unnecessary usage of keyword volatile.Shaun Ruffell
The buffers are not being accessed by the hardware at this point, and therefore do not need to be volatile. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6931 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-08-04wcte12xp: Remove the vpm_num from 'struct command'Shaun Ruffell
This member wasn't necessary anymore since the VPM commands are kept on a separate queue now. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6930 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-07-16wcte12xp: Disable vpmadt032 companding by default.Shaun Ruffell
This fixes a regression in 2.2.0 where certain configurations will fail patloop test or have repeated HDLC aborts because the VPMADT032 is modifying the clear channel or d channel data streams. This restores the behavior to how it was in dahdi-linux 2.1.0.4. (closes issue #15498) Reported by: alecdavis Tested by: alecdavis git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6844 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-06-29dahdi-base: Enable DAHDI to manage the reference counts for the board drivers.Shaun Ruffell
Adds a struct module 'owner' member to the dahdi_span structure and updates all the board drivers to set this member before registering the span. This allows the core of dahdi to maintain the reference counts on the channels itself. (closes issue #10601) Reported by: Matti git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6794 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-05-14wcte12xp: Set the syncsrc in the span appropriately.Shaun Ruffell
Before this commit, dahdi_tool would report "Internally clocked" for boards supported by the wcte12xp driver both when receiving timing from the span and providing it to the span. Now it reports "Internally clocked" if providing timeing to the span, and the card if receiving timeing from the span. DAHDI-65. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6621 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-05-11wcte12xp: Expose vpm parameters as module parameters.Shaun Ruffell
Expose the vpmnlptype, vpmnlpthresh, and vpmnlpmaxsupp as module parameters like for the wctdm24xxp. DAHDI-261 git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6590 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-05-11voicebus: Update the default vpmadt032 parameters.Shaun Ruffell
Move the echo can channel parameters into a common location for both the wcte12xp and wctdm24xxp drivers that use the voicebus module. This is intended to make it clearer which differences are required between the clients. Additionally, update the default parameters to the new recommended values. VPMADT032-37 git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6589 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-05-07voicebus: Create workqueue for each vpmadt032 instance.Shaun Ruffell
Depending on the system latency, the deferred work for the vpmadt032 can take up to 200ms. This change allows each vpmadt032 to use its own workqueue, and not the global system workqueue. This prevents vpm operations from blocking the main system workqueue for extended periods. This restores the behavior to the way it was before the common vpmadt032 code was moved out of the wctdm24xxp and wcte12xp drivers. DAHDI-260 voicebus-squash: Adding the wq name. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6572 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-05-07voicebus: Changing default NLP type to 'suppression'.Shaun Ruffell
The 'suppression' default for the NLP provides better echo canceling performance. Also ensures that the wctdm24xxp and wcte12xp driver use the same default values. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6568 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-04-30Ensure that vpmsupport=0 module parameter takes proper effectKevin P. Fleming
For these drivers, when the vpmsupport module parameter is set to zero, don't even register the span as supporting echo cancellation. DAHDI-250 git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6544 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-04-29echocan: Improve interface for echo cancelers.Shaun Ruffell
Echo cancelers are now able to report if they are able to automatically disable their NLP portions in the presence of tones in the audio stream. Also, the interface is changed to allow user space to just disable the NLP portion of the echo canceler. These changes improve fax and modem handling in DAHDI. This commit merges in the changes on http://svn.digium.com/svn/dahdi/linux/team/kpfleming/echocan_work Patch by: kpfleming Also contains improvements to CED tone detection. (closes issue #13286) Reported by: viniciusfontes git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6529 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-04-29voicebus: Move common vpmadt032 interface into voicebus module.Shaun Ruffell
The voicebus library was previously linked into both the wcte12xp and wctdm24xxp drivers. It is now broken out into it's own module and the common parts of the vpmadt032 interface are now located in that module to reduce duplication between the wcte12xp and wctdm24xxp drivers. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6527 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-04-29wcte12xp: Update cmdqueue processing.Shaun Ruffell
The command queue for reading from the registers on the framer is now stored in a linked_list instead of an array. Allows for the locks to protect this structure to be held for shorter periods of time and reduces the need to cycle through all the elements in the array to decide if there is a command in the queue to process. Remove the usecount and dead members from struct t1 since the module reference count will allow us to know when it's safe to free up the memory. This change also moves alarm processing out of the interrupt handler and removes the need for special interrupt handling of commands. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6525 a0bf4364-ded3-4de4-8d8a-66a801d63aff
