2019-01-29Rework setting the AVIRT map, and stream creationMark Farrugia1-0/+1
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.

2018-11-13Rework 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>

2018-11-08Add private data structure to PCM for audio path managementJames O'Shannessy1-0/+10
Expand upon the private data structure currently used by avirt to allow audio paths to store own user data to PCM implementation. Signed-off-by: James O'Shannessy <james.oshannessy@fiberdyne.com.au>
2018-11-01Only expose streams mapped to audiopaths on configure() cbMark Farrugia1-32/+16
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 Farrugia1-10/+1
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>
