The call of function updates the status of runtime with the latest position of audio data transmission, checks overrun and underrun over buffer, awaken user processes from waiting for available audio data frames, sampling audio timestamp, and performs stop or drain the PCM substream according to configured threshold. The function is intended to use for the case that PCM driver operates audio data frames under acquired lock of PCM substream; e.g. in callback of any operation of :c:type:`snd_pcm_ops` in process context. In any interrupt context, it's preferrable to use ``snd_pcm_period_elapsed()`` instead since lock of PCM substream should be acquired in advance. Developer should pay enough attention that some callbacks in :c:type:`snd_pcm_ops` are done by the call of function: - .pointer - to retrieve current position of audio data transmission by frame count or XRUN state. - .trigger - with SNDRV_PCM_TRIGGER_STOP at XRUN or DRAINING state. - .get_time_info - to retrieve audio time stamp if needed.

To differentiate such devices and fix bugs due to lack of device-specific configurations, this function allows DMI info to be used as the sound card long name, in the format of "vendor-product-version-board" (Character '-' is used to separate different DMI fields here). This will help the user space to load the device-specific Use Case Manager (UCM) configurations for the card.
