Hi, This patchset is a preparation for enhancement of AMDTP domain that I addressed to my previous patchset: https://mailman.alsa-project.org/pipermail/alsa-devel/2019-July/152430.html When queued packets for several IT/IR contexts in the same domain are handled in hardware IRQ context for an IT context, the number of events in the packets are mostly the same for each of contexts. This means that the size of period for PCM substreams associated to the contexts is also the same. At present, PCM substreams for the contexts can have own size of period. This commit adds a member into AMDTP domain to share the size of period for PCM substreams on AMDTP streams in the same domain. This patchset includes optimization to detect whether isochronous resources for AMDTP streams are reserved or not in pcm.open callback.
