2011-06-02Remove unused variables.Shaun Ruffell
gcc-4.6 now warns about variables that are set but never used. Clean up unused variables everywhere except the oct612x subdirectory. The oct612x should go in a separate patch in case that needs to be pulled out into a separate project again.

2011-05-31xpp: empty labels are not duplicateTzafrir Cohen
Some older Asttribanks had an empty label string. They should be ignored when testing for a duplicate label at device probe time. While we're at it, reduce panic level in the notice.

2011-05-23xpp: Remove obsolete XPP_DEBUGFS codeTzafrir Cohen
XPP_DEBUGFS code was some code used to send BRI D-Channel data through debugfs for, well, debugging. Unused in recent years. Time to remove. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9917 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2011-05-23xpp: Remove obsolete and unused OLD_PROC codeTzafrir Cohen
OLD_PROC marked old and unused code that was used for writing to procfs. It has long ago been replaced with different sysfs interfaces. Time to remove it. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9916 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2011-01-30xpp: phonedev: Cleanup method macrosTzafrir Cohen
* Caller to CALL_XMETHOD() no longer need to explicitly pass xbus (calculate xpd->xbus) * Create CALL_PHONE_METHOD() similar to CALL_XMETHOD() -- inlining the extra parameters (more readable) * Reverse parameter order in PHONE_METHOD() and CALL_PHONE_METHOD() to be consistent with XMETHOD() and CALL_XMETHOD() * Rename XPD_STATE phonedev method to card_state: - Consistency with other phonedev methods. - These calls now Wrap internal calls to XPD_STATE protocol HOSTCMD in PRI, BRI, FXS, FXO Signed-off-by: Oron Peled <oron@actcom.co.il> Acked-by: Tzafrir Cohen <tzafrir.cohen@xorcom.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9706 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2011-01-30xpp: More adaptations for non-PHONEDEV XPDsTzafrir Cohen
* Add IS_PHONEDEV(xpd) macro * Reject dahdi_register_xpd()/dahdi_unregister_xpd() for non-PHONEDEV * Make sysfs 'offhook' attribute contain '\n' if empty (no channels) * Skip PHONEDEV related xbus_tick() parts -- we still want to process the end of it for the card_tick() calls. * Remove BUG_ON() for missing phoneops (also remove old duplicate test for XBUS_IS...) * Call XPD_STATE method only for PHONEDEV XPD's Signed-off-by: Oron Peled <oron@actcom.co.il> Acked-by: Tzafrir Cohen <tzafrir.cohen@xorcom.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9705 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2011-01-30xpp: prepare for phonedev refactorTzafrir Cohen
* Allow having XPDs that represent a device that is not a span. * Refactor all span related data from 'struct xpd' to 'struct phonedev' * Refactor span related methods into 'phonedev->phoneops' * Refactor phone related initialization into phonedev_init()/phonedev_cleanup() Signed-off-by: Oron Peled <oron@actcom.co.il> Acked-by: Tzafrir Cohen <tzafrir.cohen@xorcom.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9704 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-11-04Remove mutex emulationShaun Ruffell
Using semaphores as mutexes was removed from the kernel in 4882720b267b. Just use straight semaphores now. 'DECLARE_MUTEX()' -> 'DEFINE_SEMAPHORE()' and 'init_MUTEX()' -> 'sema_init()'.

2010-09-24Move test for DEFINE_SPINLOCK into include/dahdi/kernel.hShaun Ruffell
The check for DEFINE_SPINLOCK was spread throughout the source tree. If not defined we can just define it in inlucde/dahdi/kernel.h. Now include/dahdi/kernel.h is the only place that references SPIN_LOCK_UNLOCKED (which breaks lockdep checking if DEFINE_SPINLOCK is otherwise defined in the kernel).

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
2010-07-13Keep 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
2010-07-13Solve 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
* The worker member of 'struct xbus' is now an embedded struct xbus_workqueue. * Replace wake_up() to wake_up_interruptible_all(). git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8882 a0bf4364-ded3-4de4-8d8a-66a801d63aff
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

2009-03-01New XPP code: xpp rev 6795:Tzafrir Cohen
* Fix cases where the command_queue overflowed during initialization. - Also add a 'command_queue_length' parameter to xpp.ko * More migrations to sysfs: - Add a 'transport' attribute to our astribank devices which points to the usb device we use. E.g: /sys/bus/astribanks/devices/xbus-00/transport is symlinked to ../../../../../../devices/pci0000:00/0000:00:10.4/usb5/5-4 - Move /proc/xpp/XBUS-??/XPD-??/span to /sys/bus/xpds/devices/??:?:?/span - Migrate from /proc/xpp/sync to: /sys/bus/astribanks/drivers/xppdrv/sync - New 'offhook' attribute in: /sys/bus/xpds/devices/??:?:?/offhook * PRI: change the "timing" priority to match the convention used by other PRI cards -- I.e: lower numbers (not 0) have higher priority. * FXO: - Power denial: create two module parameters instead of hard-coded constants (power_denial_safezone, power_denial_minlen). For sites that get non-standard power-denial signals from central office on offhook. - Don't hangup on power-denial, just notify Dahdi and wait for - Fix caller-id detection for the case central office sends it before first ring without any indication before. Asterisk's desicion. * USB_FW.hex: - Fixes cases where firmware loading would fail. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6046 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2008-10-16xpp: start migration from procfs to sysfs.Tzafrir Cohen
* Sysfs representation for XPDs: /sys/bus/xpds/devices/<bus>:<unit>:<subunit> * Astribanks sysfs directories now include the XPDs as subdirectories: e.g. /sys/bus/astribanks/devices/xbus-00/00:3:0 * procfs control interface deprecated: conditioned by OLD_PROC (defaults to off). Control functionality moved to sysfs: * xbus attributes: cls connector label status timing waitfor_xpds xbus_state * XPDs can have driver-specific attributes. Common attriubtes: blink chipregs span * PRI-specific attributes: pri_clocking pri_dchan pri_cas pri_alarms pri_layer1 pri_localloop pri_protocol * The Astribank attribute "xbus_state" is read/write. Reading it shows the current state of the Astribank. Writing "start" or "stop" allows a software equivalent of connect or disconnect respectively. * When an Astribank is ready it sends an "online" event. Whenever its not ready (e.g. at the time of disconnect) it sends an "offline" event. Use astribank_hook.sample to handle those. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@5097 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2008-08-11xpp: CAS/E1 support in the PRI module, and minor fixes.Tzafrir Cohen
* Add support for CAS in the PRI module. Use firmware rev. 5975. * Debugging parameter pcmtx_chan now accepts a dahdi channel number. * Do initialize a reserved protocol field (card_global). * The name DAHDI as used in proc/xpp/sync has 5 (not 6) letters. * Fix DTMF "channel leak" regression in the FXS module. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@4761 a0bf4364-ded3-4de4-8d8a-66a801d63aff
