Hello all, here's patch to document -ENODATA error as a PCM error code. We have recently merged patches to SOF firmware to use this error code: https://github.com/thesofproject/sof/pull/2918 Some additional background on the use-case: https://github.com/thesofproject/sof/issues/2564 In thread "Functionality of pcm_notify in snd-aloop?" https://mailman.alsa-project.org/pipermail/alsa-devel/2020-April/166974.html .. we discussed the possibility for ALSA to provide a mechanism for application to wait for the condition to change, but at least for the currently known usages, the synchronization responsibility will be in user-space (UCM file will describe the PCM dependencies). Anyways, this is orthogonal to documenting -ENODATA, so sending this now.
