2009-01-09mISDN: Add layer1 prim MPH_INFORMATION_REQMartin Bachem
MPH_INFORMATION provides full D- and B-Channel status overview - new layer1 primitive: MPF_INFORMATON_REQ - layer1 replies with MPH_INFORMATION_IND containing - dch->[state,Flags,nrbchan] - bch[]->[protocol,Flags] - hardware driver should send MPH_INFORMATION_IND on all ph state changes and BChannel state changes to MISDN_ID_ANY Signed-off-by: Martin Bachem <m.bachem@gmx.de> Signed-off-by: Karsten Keil <kkeil@suse.de>
2009-01-09mISDN: Create /sys/class/mISDNMatthias Urlichs

2009-01-09mISDN: Fix deactivation, if peer IP is removed from l1oip instance.Andreas Eversberg
Added GETPEER operation. Socket now checks if device is already busy at a differen mode. Signed-off-by: Andreas Eversberg <andreas@eversberg.eu> Signed-off-by: Karsten Keil <kkeil@suse.de>
2009-01-09mISDN: Add ISDN_P_TE_UP0 / ISDN_P_NT_UP0Martin Bachem
- new layer1 protocols for UP0 bus - helper #defines to test for TE/NT/S0/E1/UP0 Signed-off-by: Martin Bachem <m.bachem@gmx.de> Signed-off-by: Karsten Keil <kkeil@suse.de>
2009-01-09mISDN: Add ISDN sample clock API to mISDN coreAndreas Eversberg
Add ISDN sample clock API to mISDN core (new file clock.c) hfcmulti and mISDNdsp use clock API. Signed-off-by: Andreas Eversberg <andreas@eversberg.eu> Signed-off-by: Karsten Keil <kkeil@suse.de>
2009-01-09mISDN: Add E-Channel logging featuresMartin Bachem
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 <m.bachem@gmx.de> Signed-off-by: Karsten Keil <kkeil@suse.de>

2009-01-09mISDN: Added an ioctl to change the device nameMatthias Urlichs
To get persistent device names with hotplug we need to rename devices sometime. Signed-off-by: Matthias Urlichs <matthias@urlichs.de> Signed-off-by: Karsten Keil <kkeil@suse.de>
2009-01-09mISDN: Add feature via MISDN_CTRL_FILL_EMPTY to fill fifo if emptyAndreas Eversberg
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.

2008-08-02mISDN cleanup user interfaceKarsten Keil
The channelmap should have the same size on 32 and 64 bit systems and should not depend on endianess. Thanks to David Woodhouse for spotting this. Signed-off-by: Karsten Keil <kkeil@suse.de>
