摘要： A method is configured to increase efficiency of buffer usage within a pipeline of a computing device. The method includes creation of a buffer (120) in memory (110) of the computing device and caching of a memory descriptor list (208) by the computing device that describes the buffer in a buffer information cache (122) and has associated therewith a handle (210) that acts as a lookup to the memory descriptor list. The method also includes passing the handle through the pipeline (216) of the computing device for processing of data within the buffer by one or more stages (218,220) of the pipeline such that access to the data is obtained by the one or more stages by using the handle as the lookup as part of a call to obtain the memory descriptor list for the buffer from the buffer information cache.

摘要： User mode driver extension techniques are described. In one or more implementations, a computing device implements techniques that promote stability of execution of drivers performed by a computing device including stream preprocessing. The computing device includes a processing system to execute an operating system using a kernel mode and a user mode and memory configured to maintain instructions stored thereon that are executable by the processing system. The instructions include the operating system and a device driver and a user mode driver extension that correspond to a camera to support a communicative coupling between the camera and the operating system. The device driver is executable within the kernel mode and the user mode driver extension executable within the user mode. The user mode driver extension is configured to preprocess streams originated by the camera before processing by a camera pipeline of the operating system.
