+                   input and output devices accessible via this module.

+                 - <routes/>: list of possible connections between input
+                   and output devices or between stream and devices.
+                   A <route/> is defined by a set of 3 attributes:

+                 - <attachedDevices/>: permanently attached devices.
+                   The attachedDevices section is a list of devices names.
+                   Their names correspond to device names defined in "devicePorts" section.

+ *     is a channel mask representation for index assignment.  Each low-order
+ *     bit corresponds to a selected channel.  There is no platform
+ *     interpretation of the various bits.  There is no concept of output or
+ *     input.  It is not permitted for no bits to be set.
+ *
+ * All other representations are reserved for future use.
+ *
+ * Warning: current representation distinguishes between input and output, but
+ * this will not the be case in future revisions of the platform. Wherever there
+ * is an ambiguity between input and output that is currently resolved by
+ * checking the channel mask, the implementer should look for ways to fix it

+-----------------------------------------------------------
+WHAT WAS *NOT* DONE, and you need to do now:
+ 1) You need to choose if the new HAL is optional or not for new devices.
+    Either add or replace $BASE_VERSION by $NEW_VERSION in
+    compatibility_matrices/compatibility_matrix.current.xml
+    Do not forget to update both the "audio" and "audio.effects" HAL'
+
+ 2) Then you need to choose a device to update its audio HAL implementation:
+    a) Update the HAL manifest of your device: open your device manifest.xml
+       and replace $BASE_VERSION by $NEW_VERSION for both
+        - android.hardware.audio
+        - android.hardware.audio.effect
+    b) Go to your device device.mk (usually next to the manifest) and replace:
+        - android.hardware.audio@$BASE_VERSION-impl by
+          android.hardware.audio@$NEW_VERSION-impl
+        - android.hardware.audio.effect@$BASE_VERSION-impl by
+          android.hardware.audio.effect@$NEW_VERSION-impl

+# Implementing Health 2.1 HAL
+
+1. Install common binderized service. The binderized service `dlopen()`s
+   passthrough implementations on the device, so there is no need to write
+   your own.
+
+    ```mk
+    # Install default binderized implementation to vendor.
+    PRODUCT_PACKAGES += android.hardware.health@2.1-service
+    ```
+
+1. Delete existing VINTF manifest entry. Search for `android.hardware.health` in
+   your device manifest, and delete the whole `<hal>` entry for older versions
+   of the HAL. Instead, when `android.hardware.health@2.1-service` is installed,
+   a VINTF manifest fragment is installed to `/vendor/etc/vintf`, so there is
+   no need to manually specify it in your device manifest. See
+   [Manifest fragments](https://source.android.com/devices/architecture/vintf/objects#manifest-fragments)
+   for details.
+
+1. Install the proper passthrough implemetation.
+
+    1. If you want to use default implementation:
+
+        ```mk
+        # Install default passthrough implementation to vendor.
+        PRODUCT_PACKAGES += android.hardware.health@2.1-impl
+        ```
+
+        You are done. Otherwise, go to the next step.
+
+    1. If you want to write your own implementation,
+
+        1. Copy skeleton implementation from the [appendix](#impl).
+
+        1. Modify the implementation to suit your needs.
+
+            * If you have a board or device specific `libhealthd`, see
+              [Upgrading with  a customized libhealthd](#update-from-1-0).
+            * If you are upgrading from 1.0 health HAL, see
+              [Upgrading from Health HAL 1.0](#update-from-1-0).
+            * If you are upgrading from a customized 2.0 health HAL
+              implementation, See
+              [Upgrading from Health HAL 2.0](#update-from-2-0).
+
+        1. [Update necessary SELinux permissions](#selinux).
+
+        1. [Fix `/charger` symlink](#charger-symlink).
+
+# Upgrading with a customized libhealthd or from Health HAL 1.0 {#update-from-1-0}
+
+`libhealthd` contains two functions: `healthd_board_init()` and
+`healthd_board_battery_update()`. Similarly, Health HAL 1.0 contains `init()`
+and `update()`, with an additional `energyCounter()` function.
+
+* `healthd_board_init()` / `@1.0::IHealth.init()` should be called before
+  passing the `healthd_config` struct to your `HealthImpl` class. See
+  `HIDL_FETCH_IHealth` in [`HealthImpl.cpp`](#health_impl_cpp).
+
+* `healthd_board_battery_update()` / `@1.0::IHealth.update()` should be called
+  in `HealthImpl::UpdateHealthInfo()`. Example:
+
+  ```c++
+  void HealthImpl::UpdateHealthInfo(HealthInfo* health_info) {
+      struct BatteryProperties props;
+      convertFromHealthInfo(health_info->legacy.legacy, &props);
+      healthd_board_battery_update(&props);
+      convertToHealthInfo(&props, health_info->legacy.legacy);
+  }
+  ```
+  For efficiency, you should move code in `healthd_board_battery_update` to
+  `HealthImpl::UpdateHealthInfo` and modify `health_info` directly to avoid
+  conversion to `BatteryProperties`.
+
+* Code for `@1.0::IHealth.energyCounter()` should be moved to
+  `HealthImpl::getEnergyCounter()`. Example:
+
+  ```c++
+  Return<void> Health::getEnergyCounter(getEnergyCounter_cb _hidl_cb) {
+      int64_t energy = /* ... */;
+      _hidl_cb(Result::SUCCESS, energy);
+      return Void();
+  }
+  ```
+
+# Upgrading from Health HAL 2.0 {#update-from-2-0}
+
+* If you have implemented `healthd_board_init()` and/or
+  `healthd_board_battery_update()` (instead of using `libhealthd.default`),
+  see [the section above](#update-from-1-0)
+  for instructions to convert them.
+
+* If you have implemented `get_storage_info()` and/or `get_disk_stats()`
+  (instead of using libhealthstoragedefault), implement `HealthImpl::getDiskStats`
+  and/or `HealthImpl::getStorageInfo` directly. There is no need to override
+  `HealthImpl::getHealthInfo` or `HealthImpl::getHealthInfo_2_1` because they call
+  `getDiskStats` and `getStorageInfo` to retrieve storage information.
+
+# Update necessary SELinux permissions {#selinux}
+
+For example (replace `<device>` with the device name):
+```
+# device/<manufacturer>/<device>/sepolicy/vendor/hal_health_default.te
+# Add device specific permissions to hal_health_default domain, especially
+# if a device-specific libhealthd is used and/or device-specific storage related
+# APIs are implemented.
+```
+
+# Fix `/charger` symlink {#charger-symlink}
+If you are using `/charger` in your `init.rc` scripts, it is recommended
+(required for devices running in Android R) that the path is changed to
+`/system/bin/charger` instead.
+
+Search for `service charger` in your device configuration directory to see if
+this change applies to your device. Below is an example of how the script should
+look like:
+
+```
+service charger /system/bin/charger
+    class charger
+    user system
+    group system wakelock input
+    capabilities SYS_BOOT
+    file /dev/kmsg w
+    file /sys/fs/pstore/console-ramoops-0 r
+    file /sys/fs/pstore/console-ramoops r
+    file /proc/last_kmsg r

-/**
- * The CallbackBase class is used internally by the NeuralNetworks runtime to
- * synchronize between different threads. An asynchronous task is launched
- * paired with a callback object. When a client thread requires the output being
- * generated by the asynchronous task, the client thread can wait for the result
- * and be blocked until it has completed or a timeout condition has been
- * reached. Any wait* may safely be called concurrently, even on the same
- * callback object. When the asynchronous task has finished its workload, it
- * must immediately call "notify". If the asynchronous task has failed to launch,
- * the function that tried to launch the asynchronous task must immediately call
- * "notify". This "notify" call awakens any client threads waiting on the
- * callback object.
- *
- * The CallbackBase class implements some of the base synchronization common to
- * both PrepareModelCallback and ExecutionCallback. For consistency, any HIDL
- * callback class must inherit from CallbackBase as well as the HIDL callback
- * interface it implements.
- *
- * This class exists to enable synchronization across HIDL. When synchronization
- * is only required in the same process, consider using std::future, std::mutex,
- * std::condition_variable, or std::experimental::latch instead.

+     *
+     * Optionally, caching information may be provided for the driver to save
+     * the prepared model to cache files for faster model compilation time when
+     * the same model preparation is requested in the future. There are two
+     * types of cache file handles provided to the driver: model cache and data
+     * cache. For more information on the two types of cache handles, refer to
+     * getNumberOfCacheFilesNeeded.
+     *
+     * The file descriptors must be opened with read and write permission. A
+     * file may have any size, and the corresponding file descriptor may have

+     * to that file. The file descriptors may be closed by the client once the
+     * asynchronous preparation has finished. The driver must dup a file
+     * descriptor if it wants to get access to the cache file later.
+     *
+     * The model is prepared asynchronously with respect to the caller. The
+     * prepareModel function must verify the inputs to the preparedModel
+     * function related to preparing the model (as opposed to saving the
+     * prepared model to cache) are correct. If there is an error, prepareModel
+     * must immediately invoke the callback with the appropriate ErrorStatus
+     * value and nullptr for the IPreparedModel, then return with the same
+     * ErrorStatus. If the inputs to the prepareModel function that are related
+     * to preparing the model are valid and there is no error, prepareModel must
+     * launch an asynchronous task to prepare the model in the background, and
+     * immediately return from prepareModel with ErrorStatus::NONE. If the
+     * asynchronous task fails to launch, prepareModel must immediately invoke
+     * the callback with ErrorStatus::GENERAL_FAILURE and nullptr for the
+     * IPreparedModel, then return with ErrorStatus::GENERAL_FAILURE.
+     *
+     * When the asynchronous task has finished preparing the model, it must
+     * immediately invoke the callback function provided as an input to
+     * prepareModel. If the model was prepared successfully, the callback object
+     * must be invoked with an error status of ErrorStatus::NONE and the
+     * produced IPreparedModel object. If an error occurred preparing the model,
+     * the callback object must be invoked with the appropriate ErrorStatus
+     * value and nullptr for the IPreparedModel.
+     *
+     * Optionally, the driver may save the prepared model to cache during the
+     * asynchronous preparation. Any error that occurs when saving to cache must
+     * not affect the status of preparing the model. Even if the input arguments
+     * related to the cache may be invalid, or the driver may fail to save to

+     *     the same order when retrieving the preparedModel from cache files
+     *     with prepareModelFromCache.

+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.
