Abstract
Graphics processing systems and methods are described. A graphics processing apparatus may comprise one or more graphics processing cores, a shared buffer accessible to a user mode driver (UMD) associated with an application in an unprivileged domain, the UMD to write one or more commands to the shared buffer, and a controller parse a workload in the shared buffer to identify one or more commands in the workload, the workload added by the application executing in the unprivileged domain, associate a trigger with a command in the workload, transfer the workload to one or more components of the graphics processing apparatus for execution, and upon execution of the command associated with the trigger, sample the shared buffer to identify a new workload added to the shared buffer. The one or more components of the graphics processing apparatus automatically execute the new workload added to the shared buffer.
