2010-07-26dahdi: Move the callbacks in dahdi_span into its own structure.Shaun Ruffell
Part of preparation for adding additional callbacks to allow board drivers to advertise and support gathering pre-echocan data from hardware echocans. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8985 a0bf4364-ded3-4de4-8d8a-66a801d63aff
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
2010-07-26wcte12xp, wctdm24xxp: Updating VPMADT032 firmware to version to 1.25Shaun Ruffell
The echo canceler will now monitor if the receive signal goes over a certain threshold, and if so, freezes its adaptation to prevent loss of convergence. I.e. Fixes conditions where blowing into your handset could result in echo. Additionally, 1.25 includes improvements for handling when line conditions change from echo free to containing echo. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8983 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-26wcte12xp, wctdm24xxp: Return buffer processing to interrupt handler.Shaun Ruffell
In revision 8095, I had moved most of the buffer processing out of the interrupt handler and into a tasklet. The intended result was to enable multiple cards to interleave with one another. But once again I was bitten by the fact that there are some systems that for one reason or another do not process their tasklets in a timely enough manner for the real-time nature of TDM processing. This commit moves this processing back into the interrupt handler by default. It also limits the number of frames that the interrupt handler will process at any given time which appears to achieve the same intended result. (closes issue #17289) Tested by: alecdavis git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8982 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-26wcte12xp, wctdm24xxp: spin_lock_bh -> spin_lock_irqsaveShaun Ruffell
Will add an option to allow calling the deferred processing callback directly in the interrupt handler. It appears there are some systems which still are unable to process their tasklets in a timely fashion, especially if they get pushed out to the ksoftirqd daemon. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8981 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-07-19FXS - fix VMWI compatibility mode:Tzafrir Cohen
* If we have vmwi_ioctl=N, we should initialize the vmwi_type of all channels. We initialize it to HVAC * Fix a regression, where curly braces around empty if()'s were removed. * Also fix the VMWI_TYPE() macro, so it actually uses the 3'rd parameter. (this didn't cause damage yet, as we only used HVAC so far) git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8943 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-07-14PIC 4 rev. 7381: fix T1 returning signaling register in non-CASTzafrir Cohen
This is the second part of the partial fix in r8872, though each of the two should work independently. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8931 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-14Allow reading caps when twinstar watchdog setTzafrir Cohen
Fixes reading capabilities when the watchdog is set. In that case most of the data, as seen, e.g. in output of 'astribank_allow', was 0xFF. Xorcom rev: 7809 git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8930 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-14Set Astribank PRI before initializationTzafrir Cohen
This avoids most cases of sending garbage at startup by setting each port to tristate mode at init time (in the init script) and enable it back at DAHDI_STARTUO (end of dahdi_cfg). Upgrade note: if you have upgraded the files (including init script) but old module is still loaded, you may end up with the port not getting ever enabled and the line practically dead. In such a case, reload the new module. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8922 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-13start migrating from xbus_num() to get_xbus()/put_xbus()Tzafrir Cohen
* Now get_xbus() receive and xbus number (not poiner) and uses xbus_num() internally to map it to an xbus pointer + refcount increment. (this is atomic) * Migrate all obvious places that used xbus_num() to map bus number into a pointer, so now they use get_xbus() + put_xbus() to aquire and release an xbus. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8913 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-13PRI Astribanks always sync AB (and independent)Tzafrir Cohen
* PRI devices always get SYNC-AB (never PLL, not even for NT) * Fix Timing priority calculation accordingly. * On PRI layer1 changes, elect_syncer() is called, so we have re-election. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8909 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-13prevent handling of duplicate AstribanksTzafrir Cohen
Don't let AB which are unplugged/replugged create duplicate XBUS's (if asterisk don't close the original channels). git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8905 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-13Create /sys/devices/astribanks:Tzafrir Cohen
* Astribank devices now reside under their own top-level device. * The USB device is still used as the 'transport'. * This means the astribanks parents are NOT the USB devices. * As a result, even after a USB disconnect, we have valid sysfs representation. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8904 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-13Keep SYSFS objects after disconnectTzafrir Cohen
When the USB device disconnects, we keep references to them to make sure they don't disappear. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8900 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-13Don't reset span flag RBS on pri moduleTzafrir Cohen
Don't attempt to reset the span flag DAHDI_FLAG_RBS. At pre-registration we don't yet know if we're CAS or not. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8896 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-13don't send "duplicates" in E1 as in D4Tzafrir Cohen
Make sure we only consider T1-s to be potentially D4 (which requires sending the bits twice). This fixes occasional command-queue floods in E1 CAS. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8892 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-07-13Basic support for DAHDI_VMWI_CONFIGTzafrir Cohen
* Supports only our current NEON notification. * No more global 'vmwineon' parameter: - We expect asterisk to tell us by channel. - If 'vmwi_ioctl' is not set (it is by default), that we revert to FSK searching (expensive) and call directly our NEON code (as before). git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8887 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-13Solve race xbus_populateTzafrir Cohen
Fixes a crash resulting from a race between disconnecting and connecting Astribanks (on multi-core systems) * Use get_xbus()/put_xbus() arround xbus_populate(), so a disconnect in the middle won't release the xbus too early. * Aquire all XPDs before starting initialization and release them after it finishes (so we don't have up/down races among XPDs) git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8886 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-13put xbus->worker in xbus; wake_up_interruptible_all()Tzafrir Cohen

2010-07-13Cleanup: refcount_xpd()Tzafrir Cohen
* Change refcount_xpd(): instead of returning a pointer to the atomic counter, return directly its value (just like refcount_xbus()) * Add a refcount_xbus and refcount_xpd attributes to sysfs (for debugging) git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8878 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-07-13Don't assume hardwired pri_protocol is E1Tzafrir Cohen
When initializing registers for the "PRI" (E1/T1) module, in the case the user has not explicitly asked for E1/T1 settings in xpp.conf (pri_protocol) fall back to the current value, which is the build-time fall-back. The value is read from sysfs. Previously we implicitly assumed this value is E1. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8873 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-07-12dahdi: Explicitly ensure we don't schedule a timer for the current tick.Shaun Ruffell
As best as I can tell, when CONFIG_NO_HZ is set along with CONFIG_HZ < 250, it is possible for the system timer to exceed MAX_SOFTIRQ_RESTART. Tony Mountifield alluded that this might be a problem in the below mailing list posting, but when I was originally testing, I wasn't using CONFIG_NO_HZ and HZ < 250. http://www.mail-archive.com/asterisk-dev@lists.digium.com/msg37384.html (closes issue #17620) Reported by: seanbright git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8868 a0bf4364-ded3-4de4-8d8a-66a801d63aff
