Hi all,
I am collecting the 1.2 topology support gap and try to figure out the priority and workload about that, and what I can imagine now are:
1. Multiple BEs(SSPs) support; This may need add BE definition for SOF from tplg file.
2. Reference tplg m4 for different platforms, including byt/cht/bdw/hsw/apl/cnl. This may need enable/verify types of pipeline(e.g. src, media, low-latency) can works separately and stably.
3. Refine host component buffer size, from pipeline format to pcm capability max, and use buffer_set_size in params() for each playback/capture. This means we can support different input formats(in the capability list) with a single tplg file.
4. Dynamic/hostless pipeline support. We have requirement to switching PCM(FEs) to different BEs at runtime, and also host-less(e.g. tone may already support. SSP2->SRC->SSP4, ...). we can add kcontrols to control those host-less pipeline. 5. Add a kcontrol for each SSP BE to switch loopback on/off, for test purpose. ...
I will work on #5, then #1, then #2. I think Yan is working on something related with #3, and #4 may have dependency to #1.
Any comment about these are welcomed.
Thanks, ~Keyon
