+                   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.

+ * These are the current representations:
+ *
+ *   REPRESENTATION_POSITION
+ *     is a channel mask representation for position assignment.  Each low-order

+ *     interpretation of channel (input).  The user of a channel mask needs to
+ *     know the context of whether it is for output or input.  The constants
+ *     OUT_* or IN_* apply to the bits portion.  It is not permitted for no bits
+ *     to be set.
+ *
+ *   REPRESENTATION_INDEX
+ *     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
+ * with additional information outside of the mask.

+ * For the purposes of selecting which settings to use, it does not matter
+ * whether it comes from hwbinder or FMQ. When the below specifications say that
+ * v3_2 has settings or a PhysicalCameraSetting has settings, it could refer to
+ * either hwbinder or FMQ, whichever is specified in the struct.
+ *
+ * Below is the logic that the HAL must follow for applying the metadata
+ * settings when it receives a CaptureRequest request in
+ * processCaptureRequest_3_4. Note that HAL must be capable of storing both the
+ * request.v3_2 settings and the PhysicalCameraSetting settings for each
+ * physical device.
+ * - Case 1 - request.v3_2 has settings, request.physicalCameraSettings vector
+ *   is empty:
+ *   - Store the request.v3_2 settings, overwriting the previously stored
+ *     request.v3_2 settings and clearing all previously stored physical device
+ *     settings.
+ *   - Apply the settings from the request.v3_2 to all buffers.
+ * - Case 2 - request.v3_2 has settings, request.physicalCameraSettings vector
+ *   is not empty:
+ *   - Store the request.v3_2 settings, overwriting the previously stored
+ *     request.v3_2 settings.
+ *   - Each PhysicalCameraSetting in request.physicalCameraSettings must have
+ *     settings; if not, return error.
+ *   - For each PhysicalCameraSetting in request.physicalCameraSettings, store
+ *     the settings, overwriting the previously stored settings for this
+ *     physical camera; apply these settings to the buffers belonging to the
+ *     stream for this device.
+ *   - If there are any stored physical camera settings which do not correspond
+ *     to one of the PhysicalCameraSetting in this request, clear them.
+ *   - Apply the request.v3_2 settings to all buffers belonging to streams not
+ *     covered by one of the PhysicalCameraSetting in this request.
+ * - Case 3 - request.v3_2 does not have settings,
+ *   request.physicalCameraSettings vector is empty:
+ *   - Clear all previously stored physical device settings.
+ *   - Apply the stored request.v3_2 settings to all buffers. If there is no
+ *     stored request.v3_2 settings, return error.
+ * - Case 4 - request.v3_2 does not have settings,
+ *   request.physicalCameraSettings vector is not empty:
+ *   - If request.physicalCameraSettings does not have the same set of physical
+ *     cameras as the stored physical camera settings, return error.
+ *   - Each PhysicalCameraSetting in request.physicalCameraSettings must not
+ *     have settings; if any do have settings, return error.
+ *   - For each PhysicalCameraSetting in request.physicalCameraSettings, apply
+ *     the previously stored settings for this physical camera to the buffers
+ *     belonging to the stream for this device.
+ *   - Apply the stored request.v3_2 settings to all buffers belonging to
+ *     streams not covered by one of the PhysicalCameraSetting in this request.
+ *     If there is no stored request.v3_2 settings, return error.
+ *
+ * For the first request received by the HAL, only Case 1 and Case 2 are

+# VINTF Device Manifest
+
+In Android Pie, an `<fqname>` tag was introduced to be able to express multiple
+different versions of the same HAL in VINTF manifests (for DRM)
+in device manifest. For devices launching with previous versions of Android and
+upgrading to Android Pie, the device manifest must not use `<fqname>` to
+satisfy requirements for non-optional HALs, because older version of `libvintf`
+do not recognize it, causing errors during OTA update.
+
+Assuming that the HAL provides `@1.0::I*/default`,
+`@1.1::I*/clearkey` and `@1.1::I*/foo` instances:
+
+## Devices upgrading to Android Pie
+
+### `target-level=1` or `target-level=2`
+
+FCM (framework compatibility matrix) version 2 (released in Android Oreo MR1)
+requires DRM 1.0. If the new device manifest has Target FCM Version (i.e.
+`target-level`) 1 or 2, it should use the following snippet:
+
+```xml
+<hal format="hidl">
+    <name>android.hardware.drm</name>
+    <transport>hwbinder</transport>
+    <version>1.0</version>
+    <interface>
+        <name>ICryptoFactory</name>
+        <instance>default</instance>
+    </interface>
+    <interface>
+        <name>IDrmFactory</name>
+        <instance>default</instance>
+    </interface>
+    <fqname>@1.1::ICryptoFactory/clearkey</fqname>
+    <fqname>@1.1::IDrmFactory/clearkey</fqname>
+    <fqname>@1.1::ICryptoFactory/foo</fqname>
+    <fqname>@1.1::IDrmFactory/foo</fqname>
+</hal>
+```
+
+### `target-level=3`
+
+FCM (framework compatibility matrix) version 3 (released in Android Pie)
+requires DRM 1.1. If the new device manifest has Target FCM Version (i.e.
+`target-level`) 3, it should use the following snippet:
+
+
+```xml
+<hal format="hidl">
+    <name>android.hardware.drm</name>
+    <transport>hwbinder</transport>
+    <version>1.1</version>
+    <interface>
+        <name>ICryptoFactory</name>
+        <instance>clearkey</instance>
+        <instance>foo</instance>
+    </interface>
+    <interface>
+        <name>IDrmFactory</name>
+        <instance>clearkey</instance>
+        <instance>foo</instance>
+    </interface>
+    <fqname>@1.0::ICryptoFactory/default</fqname>
+    <fqname>@1.0::IDrmFactory/default</fqname>
+</hal>
+```
+
+## Devices launching with Android Pie
+If you have a new device launched with Android Pie (no OTA), both of the
+aforementioned snippets can be used. Besides, it is recommended to use the
+new, clearer format:
+
+```xml
+<hal format="hidl">
+    <name>android.hardware.drm</name>
+    <transport>hwbinder</transport>
+    <fqname>@1.0::ICryptoFactory/default</fqname>
+    <fqname>@1.0::IDrmFactory/default</fqname>
+    <fqname>@1.1::ICryptoFactory/clearkey</fqname>
+    <fqname>@1.1::IDrmFactory/clearkey</fqname>
+    <fqname>@1.1::ICryptoFactory/foo</fqname>
+    <fqname>@1.1::IDrmFactory/foo</fqname>
+</hal>
+```

-
-    3.1 (recommended) To remove healthd from the build, keep "overrides"
-          section, and include the following in device.mk:
-            DEVICE_FRAMEWORK_MANIFEST_FILE += \
-                system/libhidl/vintfdata/manifest_healthd_exclude.xml
-    3.2 To keep healthd in the build, remove "overrides" section.

-    class hal

-
-5. Create device/<manufacturer>/<device>/health/HealthService.cpp:
-
-#include <health2/service.h>
-int main() { return health_service_main(); }
-
-6. libhealthd dependency:
-
-6.1 If the device has a vendor-specific libhealthd.<soc>, add it to static_libs.
-
-6.2 If the device does not have a vendor-specific libhealthd, add the following
-    lines to HealthService.cpp:
-
-#include <healthd/healthd.h>
-void healthd_board_init(struct healthd_config*) {}
-
-int healthd_board_battery_update(struct android::BatteryProperties*) {
-    // return 0 to log periodic polled battery status to kernel log
-    return 0;
-}
-
-7. Storage related APIs:
-
-7.1 If the device does not implement IHealth.getDiskStats and
-    IHealth.getStorageInfo, add libstoragehealthdefault to static_libs.
-
-7.2 If the device implements one of these two APIs, add and implement the
-    following functions in HealthService.cpp:
-
-void get_storage_info(std::vector<struct StorageInfo>& info) {
-    // ...
-}
-void get_disk_stats(std::vector<struct DiskStats>& stats) {
-    // ...
-}
-
-8. Update necessary SELinux permissions. For example,
-
-# device/<manufacturer>/<device>/sepolicy/vendor/file_contexts
-/vendor/bin/hw/android\.hardware\.health@2\.0-service.<device> u:object_r:hal_health_default_exec:s0
-
-# device/<manufacturer>/<device>/sepolicy/vendor/hal_health_default.te
-# Add device specific permissions to hal_health_default domain, especially
-# if Step 6.1 or Step 7.2 is done.

+    1. To keep `healthd` in the build, remove "overrides" section.
+
+1. Create `device/<manufacturer>/<device>/health/android.hardware.health@2.0-service.<device>.rc`
+
+    ```rc
+    service vendor.health-hal-2-0 /vendor/bin/hw/android.hardware.health@2.0-service.<device>
+        class hal
+        user system
+        group system
+        capabilities WAKE_ALARM
+        file /dev/kmsg w
+    ```
+
+1. Create `device/<manufacturer>/<device>/health/HealthService.cpp`:
+
+    ```c++
+    #include <health2/service.h>
+    int main() { return health_service_main(); }
+    ```
+
+1. `libhealthd` dependency:
+
+    1. If the device has a vendor-specific `libhealthd.<soc>`, add it to static_libs.
+
+    1. If the device does not have a vendor-specific `libhealthd`, add the following
+        lines to `HealthService.cpp`:
+
+        ```c++
+        #include <healthd/healthd.h>
+        void healthd_board_init(struct healthd_config*) {}
+
+        int healthd_board_battery_update(struct android::BatteryProperties*) {
+            // return 0 to log periodic polled battery status to kernel log
+            return 0;
+        }
+        ```
+
+1. Storage related APIs:
+
+    1. If the device does not implement `IHealth.getDiskStats` and
+        `IHealth.getStorageInfo`, add `libhealthstoragedefault` to `static_libs`.
+
+    1. If the device implements one of these two APIs, add and implement the
+        following functions in `HealthService.cpp`:
+
+        ```c++
+        void get_storage_info(std::vector<struct StorageInfo>& info) {
+            // ...
+        }
+        void get_disk_stats(std::vector<struct DiskStats>& stats) {
+            // ...
+        }
+        ```
+
+1. Update necessary SELinux permissions. For example,
+
+    ```
+    # device/<manufacturer>/<device>/sepolicy/vendor/file_contexts
+    /vendor/bin/hw/android\.hardware\.health@2\.0-service\.<device> u:object_r:hal_health_default_exec:s0
+
+    # 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.
+    ```
+
+1. Implementing health HAL in recovery. The health HAL is used for battery
+status checks during OTA for non-A/B devices. If the health HAL is not
+implemented in recovery, `is_battery_ok()` will always return `true`.
+
+    1. If the device does not have a vendor-specific `libhealthd`, nothing needs to
+    be done. A "backup" implementation is provided in
+    `android.hardware.health@2.0-impl-default`, which is always installed to recovery
+    image by default.
+
+    1. If the device does have a vendor-specific `libhealthd`, implement the following
+    module and include it in `PRODUCT_PACKAGES` (replace `<device>` with appropriate
+    strings):
+
+    ```bp
+    // Android.bp
+    cc_library_shared {
+        name: "android.hardware.health@2.0-impl-<device>",
+        recovery_available: true,
+        relative_install_path: "hw",
+        static_libs: [
+            "android.hardware.health@2.0-impl",
+            "libhealthd.<device>"
+            // Include the following or implement device-specific storage APIs
+            "libhealthstoragedefault",
+        ],
+        srcs: [
+            "HealthImpl.cpp",
+        ],
+        overrides: [
+            "android.hardware.health@2.0-impl-default",
+        ],
+    }
+    ```
+
+    ```c++
+    // HealthImpl.cpp
+    #include <health2/Health.h>
+    #include <healthd/healthd.h>
+    using android::hardware::health::V2_0::IHealth;
+    using android::hardware::health::V2_0::implementation::Health;
+    extern "C" IHealth* HIDL_FETCH_IHealth(const char* name) {
+        const static std::string providedInstance{"default"};
+        if (providedInstance != name) return nullptr;
+        return Health::initInstance(&gHealthdConfig).get();
+    }
+    ```
+
+    ```mk
+    # device.mk
+    PRODUCT_PACKAGES += android.hardware.health@2.0-impl-<device>
