Graphics processing dispatch from user mode

摘要

A method, system, and computer program product are disclosed for providing improved access to accelerated processing device compute resources to user mode applications. The functionality disclosed allows user mode applications to provide commands to an accelerated processing device without the need for kernel mode transitions in order to access a unified ring buffer. Instead, applications are each provided with their own buffers, which the accelerated processing device hardware can access to process commands. With full operating system support, user mode applications are able to utilize the accelerated processing device in much the same way as a CPU.

主权项

1. A method comprising:
selecting a user mode application for scheduling by a scheduler; and dispatching commands, in a user mode, directly to an accelerated processing device from a work queue allocated to the user mode application by a kernel mode driver, the work queue being accessible to the user mode application and the accelerated processing device without transitioning to a kernel mode.
