2010-09-23wcte12xp, wctdm24xxp: Convert vbb cache from kmem_cache to dma_pool.Shaun Ruffell
The voicebus interface constantly uses the same buffers for moving data to/from the card. A fixed pool has less overhead in this case than constantly mapping/unmapping the kmem_cache_alloced buffers. Saves about ~2.608 us for each run of vb_isr on a 2.40 GHz Xeon test machine.

2010-09-21wctdm24xxp: Add optional FXO digital loopback if DEBUG is defined.Shaun Ruffell
This module parameter will allow patgen/pattest to be used only on FXO ports. *ALL* FXO ports will be placed in digital loopback mode when set. The current intent is for this to be removed as an optional module parameter when there is a channel by channel representation in sysfs. Otherwise, a new IOCTL would have to be defined and a tool written in order to support this. DAHDI-696.

2010-09-01wctdm24xxp: Minor spacing change on module parameter descriptions.Shaun Ruffell

2010-08-19dahdi: move 'dahdi_is_digital_span' back into wctdm24xp driver.Shaun Ruffell
Older kernels do not like the 'bool' type and I cannot just add it into include/dahdi/kernel.h without compile messages in the xpp driver where bool is defined directly. Since the wctdm24xxp driver is the only place using that function, I just moved it back there for now. This fixes a regression introduced in 9130. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9167 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. This work was originally on: http://svn.asterisk.org/svn/dahdi/linux/team/sruffell/improved_ecreference@9143 and includes a generic kfifo replacement by Matt Fredrickson. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9144 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-08-16wctdm24xxp: Set the companding mode on the analog ports in fixup.Russ Meyerriecks
Fixes a regression from 9101 'wctdm24xxp: Added "auto" companding option' where the analog modules were not defaulted to alaw properly when a digital module is on an Hx8. This could result in very poor audio since the modules were providing ulaw data, but dahdi-base believed the audio was in alaw when converting to signed linear. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9143 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-08-06wctdm24xxp: Added "auto" companding optionRuss Meyerriecks
Added the "auto" option for the module parameter "companding". In auto mode its left up to each card to decide what companding mode it should be in. If a BRI module is installed, it set everything to alaw; ulaw is selected if no BRI module is installed. Also fixed a bug where forcing companding one way or the other wasn't affecting the BRI modules. dahdi-673 git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9101 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-08-06wctdm24xp: Replaced alawoverride with compandingRuss Meyerriecks

2010-07-30wctdm24xxp: Prevent FXS Proslic staying in "Forward/Reverse OnHookTransfer" ↵Alec L Davis
during call [One-liner summary of changes] Now that the 3 second click after answering the call on an FXS port has been fixed, the side effect is that the Proslic during a call, still has the audio signal paths still powered on. Reading the Si3215 specs it reads that an extra ~20mA is consumed while in OHT mode.

2010-07-29SLIC_LF_OPPENDING confict between wctdm_proslic_recheck_sanity() and ↵Alec L Davis
set_lasttxhook_interruptible() Problem: 'wctdm_proslic_recheck_sanity()' is executed (4 times??) every ~256ms which monitors and clears the SLIC_LF_OPPENDING on fxs->lasttxhook when the LF state has been reached. 'set_lasttxhook_interruptible()' times out after 100ms waiting from the previous write to the SLIC_LF register, by waiting for SLIC_LF_OPPENDING to be cleared, thus the write will fail. Solution: adds wctdm_proslic_check_oppending which does the monitoring and clearing of SLIC_LF_OPPENDING, which is execute every 1ms. It also if the correct state is not reached within 100ms, resends the lasttxhook state.

2010-07-26dahdi: Remove the 'pvt' member from dahdi_span.Shaun Ruffell
The vast majority of board drivers already keep the dahdi_span structure in a driver specific structure. The others were easily converted. This way board drivers can use the container_of macro to find what was previously pointed to by the "pvt" member of the span. One less thing to think about in the span structure. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8984 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-04-03wcte12xp, wtdm24xxp: Make sure the writes are retried.Shaun Ruffell
r8454 and r8460 introduced a change where writes are not retried when other module/framer commands are retried. This was an error and wasn't what was actually under test. This commit restores the behavior in wctdm24xxp and makes sure the vpm writes are retried in the wcte12xp. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8461 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-03-01wctdm24xxp, wcte12xp: Add optional module parameter to set the maximum latency.Shaun Ruffell
Setting the maximum latency can be useful if you have a system event that normally causes a latency increase, but you would rather have a break in the audio or frame slip, then let the latency grow to the current default maximum which is 25ms.

2010-02-25wctdm24xxp: Only use the first three EFRAMES for module commands.Shaun Ruffell
On a 2.6.32.7 debug kernel with a TDM2400, this can save up to 30ms every second of processing time without any appreciable impact on runtime performance since most of the commands to the modules during normal operation are reads, and therefore only one would be in each SFRAME anyway. The impact of this change is less for TDM410 and TDM800 since they already limit the number of modules that they look for queued commands for. There is still more room for optimizing module command handling. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8096 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-02-25wctdm24xxp, wcte12xp: Buffer handling improvements.Shaun Ruffell
This patch moves the majority of the buffer processing for the voicebus based cards out of the interrupt handler and into a tasklet. When multiple cards are running on the same CPU, and there was a latency condition that would cause them to get behind, this now allows the tasklet to limit how many buffers are processed on each card before giving the other card a chance to start working on it's backlog. Additionally, when the card detects a hard under run, instead of trying to fix it up in the handling routine, it will now reschedule a work item that will completely reset the descriptor rings. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8095 a0bf4364-ded3-4de4-8d8a-66a801d63aff
