* isdn: Use ktime_t instead of 'struct timeval'Tina Ruchandani2016-03-201-1/+1
| | | | | | | | | | | | | | 'struct timeval' uses 32-bit representation for seconds which will overflow in year 2038 and beyond. mISDN/clock.c needs to compute and store elapsed time in intervals of 125 microseconds. This patch replaces the usage of 'struct timeval' with 64-bit ktime_t which is y2038 safe. The patch also replaces do_gettimeofday() (wall-clock time) with ktime_get() (monotonic time) since we only care about elapsed time here.

* mISDN: Allow to set a minimum length for transparent dataKarsten Keil2012-05-161-1/+8
| | | | | | | | | | | If the FIFO of the card is small, many short messages are queued up to the upper layers and the userspace. This change allows the applications to set a minimum datalen they want from the drivers. Create a common control function to avoid code duplication in each driver.

* mISDN: Help to identify the cardKarsten Keil2012-05-041-1/+2
| | | | | | | | | With multiple cards is hard to figure out which port caused trouble int the layer2 routines (e.g. got a timeout). Now we have the informations in the log output. Signed-off-by: Karsten Keil <kkeil@linux-pingi.de> Signed-off-by: David S. Miller <davem@davemloft.net>
* mISDN: Make layer1 timer 3 value configurableKarsten Keil2012-05-041-1/+2

* mISDN: L2 timeouts need to be queued as L2 eventKarsten Keil2012-05-041-1/+6
| | | | | | | | To be full preemptiv safe, we cannot handle a L2 timeout in the timer context itself, we should do all actions via the D-channel thread. Signed-off-by: Karsten Keil <kkeil@linux-pingi.de> Signed-off-by: David S. Miller <davem@davemloft.net>

* mISDN: Add feature via MISDN_CTRL_FILL_EMPTY to fill fifo if emptyAndreas Eversberg2009-01-091-0/+1
| | | | | | | | | | | | This prevents underrun of fifo when filled and in case of an underrun it prevents subsequent underruns due to jitter. Improve dsp, so buffers are kept filled with a certain delay, so moderate jitter will not cause underrun all the time -> the audio quality is highly improved. tones are not interrupted by gaps anymore, except when CPU is stalling or in high load.
