2019-04-08Introduce 'unconfigure' callbackMark Farrugia5-5/+73
The 'unconfigure' callback can be used to clean up the 'configured' state of an Audio Path, for when it is desired to reset the streams, and/or reload a different stream configuration. To destroy the streams, we must attempt to force their PCMs closed. Take note though, that if a PCM is being written to when an unconfigure command is issued, system instability may occur.

2019-04-01Add 'internal' streams for routing, revamp stream finalisationMark Farrugia4-29/+140
Uses the ALSA internal PCM API to create streams purely used for internal routing purposes. Adds the 'try_complete' functions for both streams and routes in an attempt to standardize the finalization of a stream or route object. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2019-03-27Rework routing systemMark Farrugia6-115/+490
- Add 'route' to snd_avirt_stream, remove from audio path - Add route checking - ensure that source ap and ink ap have compatible hw params - Add private data support for both source and sink Audio Paths, to ensure that the PCM can hold multiple private data(s). - Add ability to use copy_kernel and exttriggers from AVIRT instead of from Audio Paths - Reintroduce pcm_trigger and pcm_prepare, so that they may be called appropriately from AVIRT, rather than child Audio Paths.

2019-03-01Add ability to route audio between audio pathsMark Farrugia5-40/+305
Configfs interface for adding 'routes' is added, and allows two audio paths to chain together particular inputs/outputs, allowing for multistage audio driver handling. A particular use-case is that of an ADSP driver. We can feed in audio to it, and capture the processed, and/or mixed, audio at it's output, and direct to another audio path driver, such as the UNICENS audio driver.

2019-01-29Rework setting the AVIRT map, and stream creationMark Farrugia4-43/+79
To ensure that a stream is able to change it's mapping (before card is sealed), we cannot create the stream PCM upon setting the mapping. This had to be reworked to allow multiple setting of the mapping if so required. The PCM ops table for a given stream is now allocated and stored in the snd_avirt_stream struct, to allow retrieval and manipulation upon mapping change.

2018-11-20Ensure snd_avirt_private_free is not called if NULLMark Farrugia1-4/+4
We only want to call the snd_avirt_private_free callback if it is set. Some Audio Paths may only set the private data, and not the private free callback, so we need to accommodate for this. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-11-20Fix missing 'close' PCM callbackMark Farrugia1-0/+17
We need to have to close PCM callback set, otherwise we get a kernel crash when the PCM middle layer attempts to dereference a NULL pointer. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
2018-11-13Rework PCM ops callback mechanismMark Farrugia6-240/+73
- 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>

We only want to call the Audio Path 'configure' callback when there is at least 1 stream mapped to that Audio Path. Change the return of snd_avirt_streams_get to return the number of mapped streams for a given Audio Path. Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>

2018-11-01Only expose streams mapped to audiopaths on configure() cbMark Farrugia5-101/+106
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 Farrugia5-28/+12
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>
