摘要:
A method and apparatus for creating, updating, and using guest physical address (GPA) to host physical address (HPA) shadow translation tables for translating GPAs of graphics data direct memory access (DMA) requests of a computing environment implementing a virtual machine monitor to support virtual machines. The requests may be sent through a render or display path of the computing environment from one or more virtual machines, transparently with respect to the virtual machine monitor. The creating, updating, and using may be performed by a memory controller detecting entries sent to existing global and page directory tables, forking off shadow table entries from the detected entries, and translating GPAs to HPAs for the shadow table entries.

An electronic device is described herein. The electronic device may include a page walker module to receive a page request of a graphics processing unit (GPU). The page walker module may detect a page fault associated with the page request. The electronic device may include a controller, at least partially comprising hardware logic. The controller is to monitor execution of the page request having the page fault. The controller determines whether to suspend execution of a work item at the GPU associated with the page request having the page fault, or to continue execution of the work item based on factors associated with the page request.

Transitions to ring 0, each time an application wants to use an adjunct processor, are avoided, saving central processor operating cycles and improving efficiency. Instead, initially each application is registered and setup to use adjunct processor resources in ring 3.

Described herein are technologies related to a ensuring that graphics commands and graphics context are offloading and scheduled for consumption as the commands and graphics context are sent from coherent to non-coherent memory/fabric in a “processor to processor” handoff or transaction.

A computing device for performing scheduling operations for graphics hardware is described herein. The computing device includes a central processing unit (CPU) that is configured to execute an application. The computing device also includes a graphics scheduler configured to operate independently of the CPU. The graphics scheduler is configured to receive work queues relating to workloads from the application that are to execute on the CPU and perform scheduling operations for any of a number of graphics engines based on the work queues.
摘要:
Methods and apparatuses may prioritize the processing of high priority and low priority contexts submitted to a processing unit through separate high priority and low priority context submission ports. According to one embodiment, submission of a context to the low priority port causes contexts in progress to be preempted, whereas submission of a context to the high priority port causes contexts in progress to be paused.
