* mISDN: Add different different timer settings for hfc-pciAndreas Eversberg2009-01-091-0/+23
| | | | | | | | | | - Poll-timer can now be set from 8 to 256 samples, depending on your kernel. - If default or 128 is used, the normal controller's clock is used as before. Usage: modprobe hfcpci poll=XXX - Added some debug code for dsp buffer size. (CMX_DELAY_DEBUG) Signed-off-by: Andreas Eversberg <andreas@eversberg.eu> Signed-off-by: Karsten Keil <kkeil@suse.de>

* mISDN: Add feature via MISDN_CTRL_FILL_EMPTY to fill fifo if emptyAndreas Eversberg2009-01-091-19/+37
| | | | | | | | | | | | 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.

* Add mISDN DSPKarsten Keil2008-07-271-0/+1886
Enable support for digital audio processing capability. This module may be used for special applications that require cross connecting of bchannels, conferencing, dtmf decoding echo cancelation, tone generation, and Blowfish encryption and decryption. It may use hardware features if available. Signed-off-by: Karsten Keil <kkeil@suse.de>
