+     * This may be a very rough estimate, and is used as a hint to the camera
+     * service to determine when to disallow multiple applications from
+     * simultaneously opening different cameras advertised by the camera
+     * service.
+     *
+     * The camera service must be able to simultaneously open and use any
+     * combination of camera devices exposed by the HAL where the sum of
+     * the resource costs of these cameras is <= 100. For determining cost,

+     * the maximally resource-consuming framerate and stream size settings
+     * available in the configuration settings exposed for that device through
+     * the camera metadata.
+     *
+     * The camera service may still attempt to simultaneously open combinations
+     * of camera devices with a total resource cost > 100. This may succeed or
+     * fail. If this succeeds, combinations of configurations that are not
+     * supported due to resource constraints from having multiple open devices
+     * must fail during the configure calls. If the total resource cost is <=
+     * 100, open and configure must never fail for any stream configuration
+     * settings or other device capabilities that would normally succeed for a
+     * device when it is the only open camera device.
+     *
+     * This field may be used to determine whether background applications are
+     * allowed to use this camera device while other applications are using
+     * other camera devices. Note: multiple applications must never be allowed
+     * by the camera service to simultaneously open the same camera device.
+     *
+     * Example use cases:
+     *
+     * Ex. 1: Camera Device 0 = Back Camera
+     *        Camera Device 1 = Front Camera
+     *   - Using both camera devices causes a large framerate slowdown due to
+     *     limited ISP bandwidth.
+     *
+     *   Configuration:
+     *
+     *   Camera Device 0 - resourceCost = 51
+     *                     conflicting_devices = empty
+     *   Camera Device 1 - resourceCost = 51
+     *                     conflicting_devices = empty
+     *
+     *   Result:
+     *
+     *   Since the sum of the resource costs is > 100, if a higher-priority
+     *   application has either device open, no lower-priority applications must
+     *   be allowed by the camera service to open either device. If a
+     *   lower-priority application is using a device that a higher-priority
+     *   subsequently attempts to open, the lower-priority application must be
+     *   forced to disconnect the device.
+     *
+     *   If the highest-priority application chooses, it may still attempt to
+     *   open both devices (since these devices are not listed as conflicting in
+     *   the conflicting_devices fields), but usage of these devices may fail in
+     *   the open or configure calls.
+     *
+     * Ex. 2: Camera Device 0 = Left Back Camera
+     *        Camera Device 1 = Right Back Camera
+     *        Camera Device 2 = Combined stereo camera using both right and left
+     *                          back camera sensors used by devices 0, and 1
+     *        Camera Device 3 = Front Camera
+     *   - Due to do hardware constraints, up to two cameras may be open at
+     *     once. The combined stereo camera may never be used at the same time
+     *     as either of the two back camera devices (device 0, 1), and typically
+     *     requires too much bandwidth to use at the same time as the front
+     *     camera (device 3).
+     *
+     *   Configuration:
+     *
+     *   Camera Device 0 - resourceCost = 50

+     *                     conflicting_devices = empty
+     *
+     *   Result:

+     *   Based on the resourceCost fields, if a high-priority foreground

+     *   The highest priority application may still attempt to simultaneously
+     *   open devices 0, 2, and 3, but the HAL may fail in open or configure

+     *                          resolutions that can be used in low-power mode
+     *  - Using both front cameras (device 1, 2) at the same time is impossible
+     *    due a shared physical sensor. Using the back and "high-power" front
+     *    camera (device 1) may be impossible for some stream configurations due
+     *    to hardware limitations, but the "low-power" front camera option may
+     *    always be used as it has special dedicated hardware.

+/**
+ * TorchModeStatus:
+ *
+ * The current status of the torch mode on a given camera device, sent by a
+ * camera provider HAL via the ICameraProviderCallback::TorchModeStatusChange()
+ * call.
+ *
+ * The torch mode status of a camera device is applicable only when the camera
+ * device is present. The camera service must not call
+ * ICameraProvider::setTorchMode() to turn on torch mode of a camera device if
+ * the camera device is not present. At camera service startup time, the
+ * framework must assume torch modes are in the AVAILABLE_OFF state if the
+ * camera device is present and the camera characteristics entry
+ * android.flash.info.available is reported as true via
+ * ICameraProvider::getCameraCharacteristics() call. The same is assumed for
+ * external camera devices when they are initially connected.
+ *
+ * The camera service requires the following behaviors from the camera provider
+ * HAL when a camera device's status changes:
+ *
+ *  1. A previously-disconnected camera device becomes connected. After
+ *      ICameraProviderCallback::CameraDeviceStatusChange() is invoked to inform
+ *      the camera service that the camera device is present, the framework must
+ *      assume the camera device's torch mode is in AVAILABLE_OFF state if it
+ *      has a flash unit. The camera provider HAL does not need to invoke
+ *      ICameraProviderCallback::TorchModeStatusChange() unless the flash unit
+ *      is unavailable to use by ICameraProvider::setTorchMode().
+ *
+ *  2. A previously-connected camera becomes disconnected. After
+ *      ICameraProviderCallback::CameraDeviceStatusChange() is invoked to inform
+ *      the camera service that the camera device is not present, the framework
+ *      must not call ICameraProvider::setTorchMode() for the disconnected camera
+ *      device until it is connected again. The camera provider HAL does not
+ *      need to invoke ICameraProviderCallback::TorchModeStatusChange()
+ *      separately to inform that the flash unit has become NOT_AVAILABLE.
+ *
+ *  3. openCameraDevice() or openCameraDeviceVersion() is called to open a
+ *      camera device. The camera provider HAL must invoke
+ *      ICameraProviderCallback::TorchModeStatusChange() for all flash units
+ *      that have entered NOT_AVAILABLE state and can not be turned on by
+ *      calling ICameraProvider::setTorchMode() due to this open() call.
+ *      openCameraDevice() must not trigger AVAILABLE_OFF before NOT_AVAILABLE
+ *      for all flash units that have become unavailable.
+ *
+ *  4. ICameraDevice.close() is called to close a camera device. The camera
+ *      provider HAL must call ICameraProviderCallback::torchModeStatusChange()
+ *      for all flash units that have now entered the AVAILABLE_OFF state and
+ *      can be turned on by calling ICameraProvider::setTorchMode() again because
+ *      of sufficient new camera resources being freed up by this close() call.
+ *
+ *  Note that the camera service calling ICameraProvider::setTorchMode()
+ *  successfully must trigger AVAILABLE_OFF or AVAILABLE_ON callback for the
+ *  given camera device. Additionally it must trigger AVAILABLE_OFF callbacks
+ *  for other previously-on torch modes if HAL cannot keep multiple devices'
+ *  flashlights on simultaneously.

+ * CameraBlob:
+ *
+ * Transport header for camera blob types; generally compressed JPEG buffers in
+ * output streams.
+ *
+ * To capture JPEG images, a stream is created using the pixel format
+ * HAL_PIXEL_FORMAT_BLOB and dataspace HAL_DATASPACE_V0_JFIF. The buffer size
+ * for the stream is calculated by the framework, based on the static metadata
+ * field android.jpeg.maxSize. Since compressed JPEG images are of variable
+ * size, the HAL needs to include the final size of the compressed image using
+ * this structure inside the output stream buffer. The camera blob ID field must
+ * be set to CameraBlobId::JPEG.
+ *
+ * The transport header must be at the end of the JPEG output stream
+ * buffer. That means the jpegBlobId must start at byte[buffer_size -
+ * sizeof(CameraBlob)], where the buffer_size is the size of gralloc
+ * buffer. Any HAL using this transport header must account for it in
+ * android.jpeg.maxSize. The JPEG data itself starts at the beginning of the
+ * buffer and must be blobSize bytes long.
+ *
+ * It also supports transport of JPEG APP segments blob, which contains JPEG APP1 to
+ * APPn (Application Marker) segments as specified in JEITA CP-3451.

+ * processCaptureRequest(). Multiple processCaptureResult() calls may be

+ * Each call, all with the same frame
+ * number, may contain some subset of the output buffers, and/or the result
+ * metadata.

+ * The result structure contains the output metadata from this capture, and the

+ * If an input buffer is given in a request, the HAL must return it in one of

+ * request is pending on a stream from that physical camera. For example,
+ * if the processCaptureRequest call doesn't request on physical camera
+ * streams, the physicalCameraMetadata field of the CaptureResult being returned
+ * should be an 0-size vector. If the processCaptureRequest call requests on
+ * streams from one of the physical camera, the physicalCameraMetadata field
+ * should contain one metadata describing the capture from that physical camera.

+     * response to a single capture request. This allows, for example, the
+     * metadata and low-resolution buffers to be returned in one call, and
+     * post-processed JPEG buffers in a later call, once it is available. Each
+     * call must include the frame number of the request it is returning
+     * metadata or buffers for. Only one call to processCaptureResult
+     * may be made at a time by the HAL although the calls may come from
+     * different threads in the HAL.
+     *
+     * A component (buffer or metadata) of the complete result may only be
+     * included in one process_capture_result call. A buffer for each stream,
+     * and the result metadata, must be returned by the HAL for each request in
+     * one of the processCaptureResult calls, even in case of errors producing
+     * some of the output. A call to processCaptureResult() with neither
+     * output buffers or result metadata is not allowed.
+     *
+     * The order of returning metadata and buffers for a single result does not
+     * matter, but buffers for a given stream must be returned in FIFO order. So
+     * the buffer for request 5 for stream A must always be returned before the
+     * buffer for request 6 for stream A. This also applies to the result
+     * metadata; the metadata for request 5 must be returned before the metadata
+     * for request 6.
+     *
+     * However, different streams are independent of each other, so it is
+     * acceptable and expected that the buffer for request 5 for stream A may be
+     * returned after the buffer for request 6 for stream B is. And it is
+     * acceptable that the result metadata for request 6 for stream B is
+     * returned before the buffer for request 5 for stream A is. If multiple
+     * capture results are included in a single call, camera framework must
+     * process results sequentially from lower index to higher index, as if
+     * these results were sent to camera framework one by one, from lower index
+     * to higher index.
+     *
+     * The HAL retains ownership of result structure, which only needs to be
+     * valid to access during this call.
+     *
+     * The output buffers do not need to be filled yet; the framework must wait
+     * on the stream buffer release sync fence before reading the buffer
+     * data. Therefore, this method should be called by the HAL as soon as
+     * possible, even if some or all of the output buffers are still in
+     * being filled. The HAL must include valid release sync fences into each
+     * output_buffers stream buffer entry, or -1 if that stream buffer is
+     * already filled.
+     *
+     * If the result buffer cannot be constructed for a request, the HAL must
+     * return an empty metadata buffer, but still provide the output buffers and
+     * their sync fences. In addition, notify() must be called with an
+     * ERROR_RESULT message.
+     *
+     * If an output buffer cannot be filled, its status field must be set to
+     * STATUS_ERROR. In this case, notify() isn't required to be called with
+     * an ERROR_BUFFER message. The framework will simply treat the notify()
+     * call with ERROR_BUFFER as a no-op, and derive whether and when to notify
+     * the application of buffer loss based on the buffer status and whether or not
+     * the entire capture has failed.
+     *
+     * If the entire capture has failed, then this method still needs to be
+     * called to return the output buffers to the framework. All the buffer
+     * statuses must be STATUS_ERROR, and the result metadata must be an
+     * empty buffer. In addition, notify() must be called with a ERROR_REQUEST
+     * message. In this case, individual ERROR_RESULT/ERROR_BUFFER messages
+     * must not be sent. Note that valid partial results are still allowed

+     * submit new requests for capture while the configureStreams() call is
+     * underway.
+     *
+     * Postconditions:
+     *
+     * The HAL device must configure itself to provide maximum possible output
+     * frame rate given the sizes and formats of the output streams, as
+     * documented in the camera device's static metadata.
+     *
+     * Performance requirements:
+     *
+     * This call is expected to be heavyweight and possibly take several hundred
+     * milliseconds to complete, since it may require resetting and
+     * reconfiguring the image sensor and the camera processing pipeline.
+     * Nevertheless, the HAL device should attempt to minimize the
+     * reconfiguration delay to minimize the user-visible pauses during
+     * application operational mode changes (such as switching from still
+     * capture to video recording).
+     *
+     * The HAL should return from this call in 500ms, and must return from this
+     * call in 1000ms.
+     *
+     * A service specific error will be returned on the following conditions
+     *
+     *     INTERNAL_ERROR:
+     *         If there has been a fatal error and the device is no longer
+     *         operational. Only close() can be called successfully by the
+     *         framework after this error is returned.
+     *     ILLEGAL_ARGUMENT:
+     *         If the requested stream configuration is invalid. Some examples
+     *         of invalid stream configurations include:
+     *           - Including more than 1 INPUT stream
+     *           - Not including any OUTPUT streams
+     *           - Including streams with unsupported formats, or an unsupported
+     *             size for that format.
+     *           - Including too many output streams of a certain format.
+     *           - Unsupported rotation configuration
+     *           - Stream sizes/formats don't satisfy the
+     *             StreamConfigurationMode requirements for non-NORMAL mode, or
+     *             the requested operation_mode is not supported by the HAL.
+     *           - Unsupported usage flag
+     *         The camera service cannot filter out all possible illegal stream
+     *         configurations, since some devices may support more simultaneous
+     *         streams or larger stream resolutions than the minimum required
+     *         for a given camera device hardware level. The HAL must return an
+     *         ILLEGAL_ARGUMENT for any unsupported stream set, and then be
+     *         ready to accept a future valid stream configuration in a later
+     *         configureStreams call.

+     * No buffers are required to be successfully returned, so every buffer

+     *
+     * All requests currently in the HAL are expected to be returned as soon as
+     * possible. Not-in-process requests must return errors immediately. Any
+     * interruptible hardware blocks must be stopped, and any uninterruptible
+     * blocks must be waited on.
+     *
+     * flush() may be called concurrently to processCaptureRequest(), with the
+     * expectation that processCaptureRequest returns quickly and the
+     * request submitted in that processCaptureRequest call is treated like
+     * all other in-flight requests. Due to concurrency issues, it is possible
+     * that from the HAL's point of view, a processCaptureRequest() call may
+     * be started after flush has been invoked but has not returned yet. If such
+     * a call happens before flush() returns, the HAL must treat the new
+     * capture request like other in-flight pending requests (see #4 below).
+     *
+     * More specifically, the HAL must follow below requirements for various
+     * cases:
+     *
+     * 1. For captures that are too late for the HAL to cancel/stop, and must be
+     *    completed normally by the HAL; i.e. the HAL can send shutter/notify
+     *    and processCaptureResult and buffers as normal.
+     *
+     * 2. For pending requests that have not done any processing, the HAL must
+     *    call notify with ErrorMsg set, and return all the output
+     *    buffers with processCaptureResult in the error state
+     *    (BufferStatus.ERROR). The HAL must not place the release
+     *    fence into an error state, instead, the release fences must be set to
+     *    the acquire fences passed by the framework, or -1 if they have been
+     *    waited on by the HAL already. This is also the path to follow for any
+     *    captures for which the HAL already called notify() with
+     *    ShutterMsg set, but won't be producing any metadata/valid buffers
+     *    for. After ErrorMsg is set, for a given frame, only
+     *    processCaptureResults with buffers in BufferStatus.ERROR
+     *    are allowed. No further notifys or processCaptureResult with
+     *    non-empty metadata is allowed.
+     *
+     * 3. For partially completed pending requests that do not have all the
+     *    output buffers or perhaps missing metadata, the HAL must follow
+     *    below:
+     *
+     *    3.1. Call notify with ErrorMsg set with ErrorCode.ERROR_RESULT if some of the expected
+     *         result metadata (i.e. one or more partial metadata) won't be
+     *         available for the capture.
+     *
+     *    3.2. Call notify with ErrorMsg set with ErrorCode.ERROR_BUFFER for every buffer that
+     *         won't be produced for the capture.
+     *
+     *    3.3. Call notify with ShutterMsg with the capture timestamp
+     *         before any buffers/metadata are returned with
+     *         processCaptureResult.
+     *
+     *    3.4. For captures that will produce some results, the HAL must not
+     *         call notify with ErrorCode.ERROR_REQUEST, since that indicates complete
+     *         failure.
+     *
+     *    3.5. Valid buffers/metadata must be passed to the framework as
+     *         normal.
+     *
+     *    3.6. Failed buffers must be returned to the framework as described
+     *         for case 2. But failed buffers do not have to follow the strict
+     *         ordering valid buffers do, and may be out-of-order with respect
+     *         to valid buffers. For example, if buffers A, B, C, D, E are sent,
+     *         D and E are failed, then A, E, B, D, C is an acceptable return
+     *         order.
+     *
+     *    3.7. For fully-missing metadata, calling ErrorCode.ERROR_RESULT is
+     *         sufficient, no need to call processCaptureResult with empty
+     *         metadata or equivalent.
+     *
+     * 4. If a flush() is invoked while a processCaptureRequest() invocation

+     *    has been invoked but before flush() has returned, the capture request
+     *    provided by the late processCaptureRequest call must be treated
+     *    like a pending request in case #2 above.
+     *
+     * flush() must only return when there are no more outstanding buffers or
+     * requests left in the HAL. The framework may call configure_streams (as
+     * the HAL state is now quiesced) or may issue new requests.
+     *
+     * Note that it's sufficient to only support fully-succeeded and
+     * fully-failed result cases. However, it is highly desirable to support
+     * the partial failure cases as well, as it could help improve the flush
+     * call overall performance.
+     *
+     * Performance requirements:
+     *
+     * The HAL should return from this call in 100ms, and must return from this
+     * call in 1000ms. And this call must not be blocked longer than pipeline
+     * latency (see below for definition).
+     *
+     * Pipeline Latency:
+     * For a given capture request, the duration from the framework calling
+     * process_capture_request to the HAL sending capture result and all buffers
+     * back by process_capture_result call. To make the Pipeline Latency measure
+     * independent of frame rate, it is measured by frame count.
+     *
+     * For example, when frame rate is 30 (fps), the frame duration (time interval
+     * between adjacent frame capture time) is 33 (ms).
+     * If it takes 5 frames for framework to get the result and buffers back for
+     * a given request, then the Pipeline Latency is 5 (frames), instead of
+     * 5 x 33 = 165 (ms).
+     *
+     * The Pipeline Latency is determined by android.request.pipelineDepth and
+     * android.request.pipelineMaxDepth, see their definitions for more details.

+     * For example, a physical shutter may have been uncovered or covered,

+     * or other accessory.
+     *
+     * The state is a bitfield of potential states, and some physical configurations

+     * For example, on some devices the FOLDED state could mean that
+     * backward-facing cameras are covered by the fold, so FOLDED by itself implies
+     * BACK_COVERED. But other devices may support folding but not cover any cameras
+     * when folded, so for those FOLDED would not imply any of the other flags.
+     * Since these relationships are very device-specific, it is difficult to specify
+     * a comprehensive policy.  But as a recommendation, it is suggested that if a flag
+     * necessarily implies other flags are set as well, then those flags should be set.
+     * So even though FOLDED would be enough to infer BACK_COVERED on some devices, the
+     * BACK_COVERED flag should also be set for clarity.
+     *
+     * This method may be invoked by the HAL client at any time. It must not
+     * cause any active camera device sessions to be closed, but may dynamically
+     * change which physical camera a logical multi-camera is using for its
+     * active and future output.
+     *
+     * The method must be invoked by the HAL client at least once before the
+     * client calls ICameraDevice::open on any camera device interfaces listed
+     * by this provider, to establish the initial device state.

+     * of resource costs for the combination be <= 100.
+     *
+     * For guaranteed concurrent camera operation, the camera framework must call
+     * ICameraDevice.open() on all devices (intended for concurrent operation), before configuring
+     * any streams on them. This gives the camera HAL process an opportunity to potentially

+     * different mode. Some HALs may only have a single mode, but an example where
+     * multiple modes would be required is if a chip has different firmwares with
+     * different capabilities.
+     *
+     * When in a mode, it must be possible to perform any combination of creating

+     * ChipConcurrencyCombinations is satisfied. This means that if a chip has two

+     * that exactly one STA type or one AP_BRIDGED type can be created, but it

+     * was then there would be a single available combination
+     * [{STA} <=1, {AP_BRIDGED} <= 1].

+     * combination limits will no longer satisfied). The addition of these new
+     * interfaces must not impact the existence of interfaces that satisfy both
+     * combinations.
+     *
+     * For example, a chip with available combinations:
+     *     [{STA} <= 2, {NAN} <=1] and [{STA} <=1, {NAN} <= 1, {AP_BRIDGED} <= 1}]
+     * If the chip currently has 3 interfaces STA, STA and NAN and wants to add an
+     * AP_BRIDGED interface in place of one of the STAs then first one of the STA
+     * interfaces must be removed and then the AP interface can be created after
+     * the STA had been torn down. During this process the remaining STA and NAN
+     * interfaces must not be removed/recreated.
+     *
+     * If a chip does not support this kind of reconfiguration in this mode then
+     * the combinations must be separated into two separate modes. Before
+     * switching modes all interfaces must be torn down, the mode switch must be
+     * enacted and when it completes the new interfaces must be brought up.
