Added debug macros for Dummy AP Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Reinstate temporarily removed PCM callbacksMark Farrugia1-4/+4
These can still be used, although proceed with caution when adding new Audio Paths. The copy_user PCM callback caused lots of strife when porting the loopback driver! Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>

2018-10-26Fix DO_AUDIOPATH_CB, remove unused PCM cbs for nowMark Farrugia2-67/+51
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>

Remove hardcoded test Audio Path UID, and use dynamic Audio Path UID Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Refactor avirt_card_register, move PCM creation to it.Mark Farrugia4-31/+56
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>
2018-10-26Add card to the configure callbackMark Farrugia2-4/+5
The loopback audio path might need to add it's own controls. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>

2018-10-26Remove blocksize from audiopathMark Farrugia6-28/+24
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 Farrugia3-9/+30

2018-10-26Make pcm_ack staticMark Farrugia1-1/+1
Add missing static declaration to pcm_ack callback function 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 Farrugia4-17/+17
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 Farrugia8-350/+210
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 Farrugia6-56/+79
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 kernel crash, where kzalloc is not alloc'ing enough memory!Mark Farrugia1-2/+1
The memory originally being allocated was not for a *, but for a **, hence the kernel crashes due to memory not being adequately allocated. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Remove configure_pcm function, absorb into pcm_openMark Farrugia1-24/+10

2018-10-26Remove unused 'buffersize' avirt_alsa_dev_groupMark Farrugia2-14/+0
buffersize is only needed by the ADSP Audio Path driver, so this has been migrated there. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Remove the unnecessary allocation of substreams in avirt_alsa_dev_groupMark Farrugia3-69/+2
Substreams are actually allocated by the PCM middle layer, so we do not need to do this here Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Remove test 'value' parameter from avirt_audiopathMark Farrugia2-2/+0
This is not required any longer Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
