+ *    for software consumers;
+ *  - walk away with no data; when the consumer is hardware, it must emit
+ *    silence in this case.
+ *

+ *
+ * † - note that for output, "buffer empty, h/w consuming" has the same outcome
+ *     as "buffer not empty, h/w not consuming", but logically these conditions
+ *     are different.
+ *
+ * State machines of both input and output streams start from the 'STANDBY'
+ * state.  Transitions between states happen naturally with changes in the
+ * states of the model elements. For simplicity, we restrict the change to one
+ * element only, for example, in the 'STANDBY' state, either the producer or the
+ * consumer can become active, but not both at the same time. States 'STANDBY',
+ * 'IDLE', 'READY', and '*PAUSED' are "stable"—they require an external event,
+ * whereas a change from the 'DRAINING' state can happen with time as the buffer
+ * gets empty.
+ *
+ * The state machine for input streams is defined in the `stream-in-sm.gv` file,
+ * for output streams—in the `stream-out-sm.gv` file. State machines define how
+ * commands (from the enum 'CommandCode') trigger state changes. The full list
+ * of states and commands is defined by constants of the 'State' enum. Note that
+ * the 'CLOSED' state does not have a constant in the interface because the
+ * client can never observe a stream with a functioning command queue in this
+ * state. The 'ERROR' state is a special state which the state machine enters
+ * when an unrecoverable hardware error is detected by the HAL module.

+    <!-- Overview.
+         This example config file was copy from existing one: frameworks/av/media/libeffects/data/
+         audio_effects.xml, with effect library names updated to AIDL libraries we currently have.
+
+         All "library" attributes in "effect" element must must match a "library" element with the
+         same value of the "name" attribute.
+         All "effect" attributes in "preprocess" and "postprocess" element must match an "effect"
+         element with the same value of the "name" attribute.
+
+         AIDL EffectFactory are relying on the "name" attribute in "effect" element to identify the
+         effect type, so it's necessary to have the mapping from name to effect type UUID. Make
+         sure to either use existing effect name as key of
+         ::android::hardware::audio::effect::kUuidNameTypeMap, or add a new {name, typeUUID} map
+         item to the kUuidNameTypeMap.
+
+         Existing audio_effects.xml should working without any change as long as:
+         1. "path" attribute of "library" element matches with the actual effect library name.
+         2. "name" attribute of "effect" and "effectProxy" element correctly added as key of
+            kUuidNameTypeMap, with value matches Identity.type in Descriptor.aidl.
+         3. "uuid" attribute of "effect" element matches Identity.uuid in Descriptor.aidl.
+         4. "uuid" attribute of "effectProxy" element matches Identity.proxy in Descriptor.aidl.

+# KeyMint HAL
+
+This directory contains the HAL definition for KeyMint. KeyMint provides
+cryptographic services in a hardware-isolated environment.
+
+Note that the `IRemotelyProvisionedComponent` HAL, and it's associated types,
+used to also be defined in this directory. As of Android U, this HAL has been
+moved to a different directory (../rkp). This move is ABI compatible, as the
+interfaces have been maintained. The build is split so that the generated
+code may be built with different options.
