    Abstract: Disclosed here in are systems and methods for mapping environment information. In some embodiments, the systems and methods are configured for mapping information in a mixed reality environment. In some embodiments, the system is configured to perform a method including scanning an environment including capturing, with a sensor, a plurality of points of the environment; tracking a plane of the environment; updating observations associated with the environment by inserting a keyframe into the observations; determining whether the plane is coplanar with a second plane of the environment; in accordance with a determination that the plane is coplanar with the second plane, performing planar bundle adjustment on the observations associated with the environment; and in accordance with a determination that the plane is not coplanar with the second plane, performing planar bundle adjustment on a portion of the observations associated with the environment.

    Abstract: Systems and methods may provide for using audio output device driver logic to maintain one or more states of an audio accelerator in a memory store, detect a suspend event, and deactivate the audio accelerator in response to the suspend event. In addition, firmware logic of the audio accelerator may be used to detect a resume event with respect to the audio output accelerator, and retrieve one or more states of the audio accelerator directly from the memory store in response to the resume. Thus, the retrieval of the one or more states can bypass the driver logic.

    Abstract translation: 系统和方法可以提供使用音频输出设备驱动器逻辑来维护存储器存储器中的音频加速器的一个或多个状态，检测挂起事件，以及响应于挂起事件停用音频加速器。 此外，可以使用音频加速器的固件逻辑来检测关于音频输出加速器的恢复事件，并且响应于恢复，直接从存储器存储器检索音频加速器的一个或多个状态。 因此，一个或多个状态的检索可以绕过驱动器逻辑。
