2011-08-11dahdi_dynamic: Call dahdi_receive in rx packet handler.Shaun Ruffell
Currently dahdi_receive is called on all channels in the context of the master dynamic span. If one span (not the master) receive two packets before the master span received a packet, the older packet on the dynamic span would end up lost because the "readchunk" for the channels would be overwritten by the new packet. DAHLIN-245 Signed-off-by: Wagner Gegler <wagner@aligera.com.br> (License #6268) Changed dahdi_ec_chunk to dahdi_ec_span.

2011-05-27Move 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).

2010-07-26dahdi: Move the 'owner' field from dahdi_span to dahdi_span_ops.Shaun Ruffell
One more thing that can be moved out of the per-span structure. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8986 a0bf4364-ded3-4de4-8d8a-66a801d63aff
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

2010-02-25dahdi_dynamic: Add TDMoE Multi-Frame support.Shaun Ruffell
Add TDMoE Multi-Frame support as described in the article at the following URL: http://www.thrallingpenguin.com/articles/tdmoe-mf.htm TDMoE-MF is known to be implemented in hardware solutions from Redfone Communications. This patch additionally implements RCU within dahdi_dynamic to decrease lock contention, latency, and context switching. Because of the use of RCU locking, all prior known issues with loading and unloading of the modules are resolved, providing the spans are shutdown with "dahdi_cfg -s". It also contains an attempt, which works, at fixing a kernel change with skb_linearize(). The use of kernel version number does not work with SuSE SLES 10, as it appears they have backported the 2.6.18 change in to their 2.6.16 version. This merges in the work Jbenden did at: http://svn.digium.com/svn/dahdi/team/jbenden/tdmoe-mf@8102 (issue #13483) Patch by: JBenden Reported by: JBenden Tested by: JBenden git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8103 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.
