2019-03-27Remove snd_avirt_pcm_period_elapsed, format tidyMark Farrugia1-3/+3
We do not need this wrapper function any longer, can use snd_pcm_period_elapsed instead. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-11-13Rework PCM ops callback mechanismMark Farrugia1-1/+2
- Fix issues regarding PCM ops callbacks via AVIRT - As PCMs are created, the PCM ops are set according to the Audio Path's needs. A default PCM ops table is applied for all PCMs, which includes callbacks such as open, and hw_free, since AVIRT requires these for intermediate processing, whether or not a given Audio Path may need them. - Separate PCM ops into separate playback and capture ops tables Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-11-01Only expose streams mapped to audiopaths on configure() cbMark Farrugia1-8/+5
When the configure() callback occurs for each audiopath, we only want those streams that are mapped to the given audiopath to be exposed to the audiopath. E.g. only streams mapped to loopback should be propagated to loopback via configure() callback, rather than all streams. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-31Remove coreinfo, absorb version info into coreMark Farrugia1-5/+3
Since coreinfo only has version info, and this is not being used at all, we can absorb the version info into the private avirt_core structure. We could in future implement a function to retrieve the version, when, and if, it is required. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Refactor all avirt_ symbols to have have snd prefix, as per Linux soundMark Farrugia2-13/+13
This will aid the eventual migration the the upstream mainline Linux kernel Fix some checkpatch warnings, and other compiler warnings Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Move system-leavel header to sound directoryMark Farrugia2-2/+2
Change include guards to reflect Linux sound driver format Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Remove unused MODULE_SUPPORTED_DEVICE macros, removed obsolete commentsMark Farrugia1-2/+8
Added debug macros for Dummy AP Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Update license headersMark Farrugia1-5/+9
All license headers need to be uniform across AVIRT Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Fix module authors/descriptionsMark Farrugia1-3/+3
These need to be in the format the Linux expects, and uniform across AVIRT Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Add card to the configure callbackMark Farrugia1-3/+3
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 Farrugia1-1/+0
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>
2018-10-26Add configfs interface, revamp stream groupingMark Farrugia1-1/+21
Add additional callbacks for audio path configuring, after card has been sealed. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-10-26Refactor top-level AVIRT API to be avirt_<subject>_<action>Mark Farrugia1-2/+2
This makes for a more organized function/variable naming convention 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 Farrugia1-0/+1
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>
2018-10-26Remove test 'value' parameter from avirt_audiopathMark Farrugia1-1/+0
This is not required any longer Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
