- PCM mode bits and masks.
- "ALSA": operations triggered by applications via ALSA
- "MONITOR": software monitoring
- "IMPULSE": optional impulse response operation
+ PCM mode bits.
+
+ There are several features of the Line6 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 several constants of
+ the form LINE6_BIT_PCM_<subsystem>_<direction>_<resource> with the
+ following meanings:
+ *) <subsystem> is one of
+ -) ALSA: PCM playback and capture via ALSA
+ -) MONITOR: software monitoring
+ -) IMPULSE: optional impulse response measurement
+ *) <direction> is one of
+ -) PLAYBACK: audio output (from host to device)
+ -) CAPTURE: audio input (from device to host)
+ *) <resource> is one of
+ -) BUFFER: buffer required by PCM data stream
+ -) STREAM: actual PCM data stream
+
+ The subsystems call line6_pcm_acquire() to acquire the (shared)
+ resources needed for a particular operation (e.g., allocate the buffer
+ for ALSA playback or start the capture stream for software monitoring).
+ When a resource is no longer needed, it is released by calling
+ line6_pcm_release(). Buffer allocation and stream startup are handled
+ separately to allow the ALSA kernel driver to perform them at
+ appropriate places (since the callback which starts a PCM stream is not
+ allowed to sleep).

+ zsmalloc is a slab-based memory allocator designed to store
+ compressed RAM pages. zsmalloc uses virtual memory mapping
+ in order to reduce fragmentation. However, this results in a
+ non-standard allocator interface where a handle, not a pointer, is
+ returned by an alloc(). This handle must be mapped in order to
+ access the allocated space.
