2018-10-26Fix DO_AUDIOPATH_CB, remove unused PCM cbs for nowMark Farrugia1-0/+1
We don't want to return inside the macro call necessarily. Some PCM cbs require differing return values. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Refactor avirt_card_register, move PCM creation to it.Mark Farrugia1-21/+51
When creating the PCMs we need information regarding the stream's mapping. For the loopback, we need to add both playback and capture substreams. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Refactor to use new DINFO macrosMark Farrugia1-18/+18
Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Remove blocksize from audiopathMark Farrugia1-3/+2
This is no longer needed in AVIRT, since it is only actually used for the ADSP Audio Path. Clean up white space, add function documentation, remove out of place debug prints Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Move 'streams_sealed' to avirt_coreMark Farrugia1-3/+20
Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Ensure no buffer overflow when setting card descriptionMark Farrugia1-3/+4
Sanity guard the sound card string buffers with strncpy Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Clean up sound card on module exitMark Farrugia1-0/+1
Sound card was not being free'd properly on module exit. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Add configfs interface, revamp stream groupingMark Farrugia1-204/+150
Add additional callbacks for audio path configuring, after card has been sealed. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Fix memory freeing of capture/playback streamsMark Farrugia1-4/+4
Since playback and capture streams are not always assigned, we do not want to error when one or the other is not present for free'ing. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Refactor top-level AVIRT API to be avirt_<subject>_<action>Mark Farrugia1-8/+8
This makes for a more organized function/variable naming convention Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Create avirt_stream structure in place of old config structuresMark Farrugia1-44/+74
Remove unnecessary extra memory allocation with the old config structures. We can store the snd_pcm pointer, which contains lots of info already. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Add 'uid' field to AP, store AP in PCM private data, fix helper macrosMark Farrugia1-14/+19
We want to use a UID when registering APs, that must start with "ap_", and acts as a unique identifier for each AP. To move forward with the adoption of routing PCMs to differing APs, we now store the AP in the PCM private data - set at pcm_open. A fix to the helper macros now allows additional args to be passed in for inclusion to the debug string Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Fix warnings generated by checkpatch.plMark Farrugia1-6/+7

2018-10-26Remove remnant debug printMark Farrugia1-1/+0
Remove leftover debug prints that are no longer needed. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Move ALSA info into coreinfo, for export to Audio PathsMark Farrugia1-10/+3
Remove the avirt_alsa_driver Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Add additional NULL checksMark Farrugia1-3/+2
Check for NULL pointers before free'ing memory on cleanup of AVIRT Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Fix initialization of the audiopath_listMark Farrugia1-4/+1
This wasn't being initialised properly, and NULL audiopaths were not being detected. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Loopback progressJames O'Shannessy1-6/+12
Loopback currently reads from dma_area but the initial copy from playback to capture has not been implemented. Signed-off-by: James O'Shannessy <james.oshannessy@fiberdyne.com.au>
