+ * Wrapper around wake lock acquisition functions (acquire/release_wake_lock) that provides a
+ * RAII-style mechanism for keeping a wake lock held for the duration of a scoped block.
+ * When a ScopedWakelock is created, it increments the reference count stored in the HalProxy
+ * for the sub-HALs specific wake lock, acquiring the wake lock if necessary. When the object goes
+ * out of scope, the ref count is decremented, potentially releasing the wake lock if no other
+ * references to the wake lock exist.
+ *
+ * This class is allocated through the createScopedWakelock callback inside the IHalProxyCallback
+ * provided to sub-HALs during initialization and should be used for all wake lock acquisition
+ * inside of the sub-HAL to ensure wake locks are not held indefinitely.
+ *
+ * The most prevalent use case for this class will be for posting events to the framework through
+ * the postEvents HalProxy callback. The expectation is that sub-HALs will create this
+ * ScopedWakelock through the createScopedWakelock upon receiving a sensor events. The lock boolean
+ * provided to createScopedWakelock will be set the according to whether the sensor events are
+ * from wakeup sensors. Then, the sub-HAL will perform any processing necessary before invoking the
+ * postEvents callback passing in the previously created ScopedWakelock. At this point, ownership
+ * of the object will be passed to the HalProxy that will then be responsible for ensuring any
+ * wake locks continue to be held, if necessary.

+This directory contains a modified version of the default implementation
+provided for sensors HAL 2.0 to support multi-HAL 2.0. It should be used as a
+means to verify the multi-HAL 2.0 implementation can successfully load and
+interact with sub-HALs.
+
+This sub-HAL implementation has two macros that can be used to configure support
+for different sets of sensors. One "SUPPORT_CONTINUOUS_SENSORS", enables
+support for continuous sensors like accel, and gyro whereas the other
+"SUPPORT_ON_CHANGE_SENSORS" enables support for on change sensors like the
+light and proximity sensor. A build target is defined for each of these macros,
+but more targets could be added to support both in one sub-HAL or none at all,
+if necessary.
+
+When built, the library will be written to
+out/target/product/<device>/vendor/lib64/android.hardware.sensors@2.0-fakesubhal.so
+
+Take this .so and place it where the multi-HAL config will cause the HalProxy to
+look and then restart the system server with adb shell stop / adb shell start
+to cause the multi-HAL to restart and attempt to load in the sub-HAL.
