2018-10-26Add configfs test scriptMark Farrugia1-0/+17
Add initial bash script for configuring AVIRT via the configfs Linux filesystem Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Add configfs interface, revamp stream groupingMark Farrugia9-344/+548
Add additional callbacks for audio path configuring, after card has been sealed. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
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
No longer any need for the configure_pcm function in it's current form. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>

2018-10-26Move ALSA info into coreinfo, for export to Audio PathsMark Farrugia5-123/+69
Remove the avirt_alsa_driver Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Remove leftover variable 'hw_frame_idx'Mark Farrugia1-7/+3
Remove remnant of earlier implementation Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
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>

2018-10-26Fix initialization of the audiopath_listMark Farrugia1-4/+1
