There are several features of the Line 6 USB driver which require PCM data to be exchanged with the device: *) PCM playback and capture via ALSA *) software monitoring (for devices without hardware monitoring) *) optional impulse response measurement However, from the device's point of view, there is just a single capture and playback stream, which must be shared between these subsystems. It is therefore necessary to maintain the state of the subsystems with respect to PCM usage.
We define two bit flags, "opened" and "running", for each playback or capture stream. Both can contain the bit flag corresponding to LINE6_STREAM_* type, LINE6_STREAM_PCM = ALSA PCM playback or capture LINE6_STREAM_MONITOR = software monitoring IMPULSE = optional impulse response measurement The opened flag indicates whether the buffer is allocated while the running flag indicates whether the stream is running.
For monitor or impulse operations, the driver needs to call line6_pcm_acquire() or line6_pcm_release() with the appropriate LINE6_STREAM_* flag.
