2010-11-25dahdi: dahdi_ioctl_iomux should return 0 on success.Shaun Ruffell
This fixes a regression introduced in revision r9466. Before this patch one might see "I/O MUX failed: Success" messages on the Asterisk console since the return from ioctl was > 0.

2010-11-04wctdm24xxp: Replace 'schluffen()' with 'interruptible_sleep_on()'Shaun Ruffell
'schluffen()' essentially duplicates the functionality of the standard Linux 'interruptible_sleep_on()' function. There may still be some race conditions that can be closed here, but most of the command queue processing is sloted for conversion to something more like in the single span driver in order to reduce the time in interrupt context spent scanning for commands to the modules.

2010-11-04dahdi: Close race between checking IOMUX condition and sleeping.Shaun Ruffell
wake_up_interruptible() will change the state of waiting tasks back to TASK_RUNNING, therefore, we want to ensure we set TASK_INTERRUPTIBLE before checking the conditions that we're going to sleep on. In practice, this closes a small window were the caller may be put to sleep when the condition is true, and have to wait for another event to come in order to wake from the sleep.

2010-09-24dahdi: Remove bigzaplock by converting chan_lock to spinlock_t.Shaun Ruffell
The bigzaplock was used to prevent changes to all the channels during masterspan processing while conference parameters were changing. The master span processing also took a global lock out on the chan_lock to prevent new channels from being registered or unregistered during processing. Instead of grabbing both those locks, just changing the semantics of chan_lock to those of bigzaplock seems to fit the bill and removes another lock from the driver (and saves ~10 ns on a 2.40 GHz Xeon in prcocess_masterspan) chan_lock is a candidate for conversion to RCU but usage in conferencing (bigzaplock type usage) needs to be audited carefully before conversion.

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).

2010-09-24dahdi: Allow core DAHDI software timing to work when DAHDI_CHUNKSIZE > 8.Shaun Ruffell
When no hardware spans are configured DAHDI will use a kernel timer in order provide timing for conferences. This is what dahdi_dummy historically was used for. When kernel timers are used to provide timing DAHDI can both potentially slow the rate at which time timer runs and also needs to account for how many milliseconds of audio are processed for each 'tick' of process_masterspan. The result is that if you are only using DAHDI for app_meetme, you can change DAHDI_CHUNKSIZE to 40 (5ms) or 80 (10ms) bytes to reduce overhead since user space is dealing with chunks of 20ms by default anyway. NOTE: If you set this, you may still need to comment out the board drivers in drivers/dahdi/Kbuild since they all do not support operating with a DAHDI_CHUNKSIZE != 8 currently.

2010-09-24dahdi: Only disable/enable interrupts once when iterating through channels.Shaun Ruffell
dahdi_receive, dahdi_transmit, and dahdi_ec_span are mostly called from interrupt context anyway, so we can save a few cycles by not saving and restoring the interrupt flags for every channel. On one 2.40GHz Xeon test machine, for a span with 24 channels w/o echocan enabled with ~10000 samples: Function Avg Before Avg After ====================================== dahdi_receive 2.109 us 1.547 us dahdi_transmit 3.203 us 2.766 us dahdi_ec_span 0.416 us 0.454 us NOTE: The time went up slightly on dahdi_ec_span since I did not have software echocan enabled and this change calls local_irq_save regardless in dahdi_ec_span. The slight increase in processing time in this case is overshadowed by the savings in dahdi_receive and dahdi_transmit. If echocan was enabled on all the channels there would be a time savings in that dahdi_ec_span too. When dahdi_receive/dahdi_transmit are called every millisecond (when DAHDI_CHUNKSIZE == 8) this saves ~0.1% CPU time for each span.
