摘要： A method and system for shared virtual memory between a central processing unit (CPU) and a graphics processing unit (GPU) of a computing device are disclosed herein. The method includes allocating a surface within a system memory. A CPU virtual address space may be created, and the surface may be mapped to the CPU virtual address space within a CPU page table. The method also includes creating a GPU virtual address space equivalent to the CPU virtual address space, mapping the surface to the GPU virtual address space within a GPU page table, and pinning the surface.

摘要： An apparatus and method are described for implementing memory management in a graphics processing system. For example, one embodiment of an apparatus comprises: a first plurality of graphics processing resources to execute graphics commands and process graphics data; a first memory management unit (MMU) to communicatively couple the first plurality of graphics processing resources to a system-level MMU to access a system memory; a second plurality of graphics processing resources to execute graphics commands and process graphics data; a second MMU to communicatively couple the second plurality of graphics processing resources to the first MMU; wherein the first MMU is configured as a master MMU having a direct connection to the system-level MMU and the second MMU comprises a slave MMU configured to send memory transactions to the first MMU, the first MMU either servicing a memory transaction or sending the memory transaction to the system-level MMU on behalf of the second MMU.

摘要： Methods and apparatus relating to techniques for reference voltage control based on error detection are described. In an embodiment, modification to a reference voltage (to be supplied to one or more components of a processor) is based at least in part on error detection to be detected for a reference circuit. In another embodiment, modification is made to a power characteristic of a processor in response to a determination that the processor is to execute a safety critical application. The modification may include adjustment to an operating frequency and/or an operating voltage of the processor. Other embodiments are also disclosed and claimed.

摘要： Methods and systems may provide for receiving, at a controller, a notification of a workload submission by an application lacking system level privileges. Additionally, the controller may be used to schedule a transfer of the workload submission to a graphics hardware component for execution, wherein the controller has system level privileges. In one example, the transfer bypasses an operating system and a kernel mode driver associated with the graphics hardware component.
