摘要： Techniques are disclosed for processing rendering engine workload of a graphics system in a secure fashion, wherein at least some security processing of the workload is offloaded from software-based security parsing to hardware-based security parsing. In some embodiments, commands from a given application are received by a user mode driver (UMD), which is configured to generate a command buffer delineated into privileged and/or non-privileged command sections. The delineated command buffer can then be passed by the UMD to a kernel-mode driver (KMD), which is configured to parse and validate only privileged buffer sections, but to issue all other batch buffers with a privilege indicator set to non-privileged. A graphics processing unit (GPU) can receive the privilege-designated batch buffers from the KMD, and is configured to disallow execution of any privileged command from a non-privileged batch buffer, while any privileged commands from privileged batch buffers are unrestricted by the GPU

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.

摘要： Methods and systems may provide for storing a set of post-synchronization operations to a graphics memory and sending a flush marker to a graphics pipeline. Additionally, the set of post-synchronization operations may be processed in response to the flush marker exiting the graphics pipeline. In one example, the set of post-synchronization operations includes one or more atomic operations. Moreover, the set of post-synchronization operations may be obtained from an inline portion of an atomics command.
