2012-09-13mISDN: Fix wrong usage of flush_work_sync while holding locksKarsten Keil1-1/+1
It is a bad idea to hold a spinlock and call flush_work_sync. Move the workqueue cleanup outside the spinlock and use cancel_work_sync, on closing the channel this seems to be the more correct function. Remove the never used and constant return value of mISDN_freebchannel. Signed-off-by: Karsten Keil <[email protected]> Cc: <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2012-05-16mISDN: Implement MISDN_CTRL_RX_OFF for more driversKarsten Keil1-0/+3
MISDN_CTRL_RX_OFF is a meachanism to discard RX data in the driver if the data is not needed by the application. It can be used when playing mesages, but not recording or with unidirectional protocols. Signed-off-by: Karsten Keil <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2012-05-16mISDN: Implement MISDN_CTRL_FILL_EMPTY for more driversKarsten Keil1-1/+3
MISDN_CTRL_FILL_EMPTY is a meachanism to send a fixed value (normally silence) as long no data from upper layers is available. It can be used when recording voice messages or with unidirectional protocols. Signed-off-by: Karsten Keil <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2012-05-16mISDN: Allow to set a minimum length for transparent dataKarsten Keil1-3/+10
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. Signed-off-by: Karsten Keil <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2012-05-16mISDN: Reduce RX buffer allocation for transparent dataKarsten Keil1-0/+1
We did allways allocate maxsize buffers, but for transparent data we know the actual size. Use a common function to calculate size and detect overflows. Signed-off-by: Karsten Keil <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2012-05-16mISDN: Early confirm for transparent dataKarsten Keil1-1/+0
It is better to send a confirm for transparent data early as possible to avoid TX underuns. Signed-off-by: Karsten Keil <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2012-05-04mISDN: Make layer1 timer 3 value configurableKarsten Keil1-0/+3
For certification test it is very useful to change the layer1 timer3 value on runtime. Signed-off-by: Karsten Keil <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2009-07-25mISDN: Make clearing B-channel a common functionKarsten Keil1-0/+1
Clearing B-channel is needed in every driver, so it makes sense to have it as common function. Signed-off-by: Karsten Keil <[email protected]>
2009-06-11mISDN: cleanup mISDNhw.hKarsten Keil1-10/+0
Remove unused stuff. Signed-off-by: Karsten Keil <[email protected]>
2009-05-25mISDN: Echo canceler now gets delay information from hardwareAndreas Eversberg1-1/+1
Added tx-fifo information for calculation of current delay to sync tx and rx streams for echo canceler. Signed-off-by: Andreas Eversberg <[email protected]> Signed-off-by: Karsten Keil <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2009-01-09mISDN: Add E-Channel logging featuresMartin Bachem1-0/+1
New prim PH_DATA_E_IND. - all E-ch frames are indicated by recv_Echannel(), which pushes E-Channel frames into dch's rqueue - if dchannel is opened with channel nr 0, no E-Channel logging is requested - if dchannel is opened with channel nr 1, E-Channel logging is requested. if layer1 does not support that, -EINVAL in return is appropriate Signed-off-by: Martin Bachem <[email protected]> Signed-off-by: Karsten Keil <[email protected]>
2009-01-09mISDN: Add feature via MISDN_CTRL_FILL_EMPTY to fill fifo if emptyAndreas Eversberg1-12/+13
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.
