Attention is currently required from: fixeria. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmocom-bb/+/30337 to look at the new patch set (#2). Change subject: mobile: integrate GAPK based audio (voice) I/O support ...................................................................... mobile: integrate GAPK based audio (voice) I/O support This change introduces a new feature to the mobile application - audio I/O support, which allows the user to speak right from the host side running mobile through its ordinary mic and speakers. The audio I/O is based on libosmo-gapk, which offers ALSA sound sysyem support. The libosmo-gapk's API implies to use the processing chains and queue, which basically consist of a source block, several processing blocks, and a sink block. So, there are two voice processing chains: - 'pq_audio_source' (voice capture -> frame encoding), - 'pq_audio_sink' (frame decoding -> voice playback). Both of them exchange frames from two dedicated buffers: - 'tch_fb_ul' - a buffer for to be played DL TCH frames, - 'tch_fb_dl' - a buffer for encoded UL TCH frames. In its turn, both buffers are served by a new gapk_io_dequeue() function, which is being called within the mobile_work() loop.
