摘要： A mechanism is described for facilitating efficient scheduling of graphics workloads at computing devices. A method of embodiments, as described herein, includes receiving a work request for processing a work item at a graphics processor, where the work request is placed by an application. The method may further include allowing the application to directly call into a graphics driver associated with the graphics processor to generate a work queue for the work item, where direct calling allows the application to bypass an intermediary call to the graphics driver and directly submit the work item to the graphics processor, where direct calling further includes notifying the graphics processor of the work unit by writing into a memory location monitored by the graphics processor. The method may further include submitting the work item from the work queue to a submit queue of a plurality of submit queues, where one or more tasks associated with the work item are processed at the graphics processor.

摘要： A virtual-to-virtual page table maps a main surface containing the actual data and a metadata or auxiliary surface that gives information about compression of the main surface. In order to access the metadata that corresponds to main surface, an additional virtual-to-virtual table may be used ahead of the regular page table mapping to avoid the need to pass the metadata base address and x, y coordinates across a pipeline which may result in multiple memory writes.
摘要翻译：虚拟到虚拟页面表映射包含实际数据的主表面和提供关于主表面的压缩的信息的元数据或辅助表面。为了访问与主表面相对应的元数据，可以在常规页表映射之前使用额外的虚拟到虚拟表，以避免需要将元数据基地址和x，y坐标通过管道传递导致多次写入内存。

摘要： By scheduling/managing workload submission to a POSH pipe one can exploit parallelism with minimum impact to the software scheduler in some embodiments. Software separates command sequences for each pipe to enable the POSH pipe to run ahead of a Render pipe. Infrastructre is provided to synchronize the two pipes through software inserted commands. A Render plus POSH pipeline may be a single monolithic engine without changes to a software scheduler, removing the complexity and the latencies involved in scheduling.
摘要翻译：通过调度/管理到POSH管道的工作负载，可以在一些实施例中利用对软件调度器的最小影响的并行性。软件分离每个管道的命令序列，以使POSH管道能够在渲染管道之前运行。提供了基础设施，通过软件插入的命令来同步两个管道。渲染加POSH管道可以是单个单片引擎，而不改变软件调度器，消除了调度中涉及的复杂性和延迟。
