Abstract: In response to executing a specified command packet, a processing unit prefetches commands stored at an indirect buffer a command queue for execution, prior to executing a command that initiates execution of the commands stored at the indirect buffer. By prefetching the data prior to executing the indirect buffer execution command, the processing unit reduces delays in processing the commands stored at the indirect buffer.

Abstract: An apparatus includes a plurality of virtual machines, a hypervisor coupled to the plurality of virtual machines, and a graphical processing unit (GPU) coupled to the hypervisor. The plurality of virtual machines are allocated a plurality of time slices. The hypervisor initiates a world switch to a first virtual machine of the plurality of virtual machines. The GPU makes a determination as to whether to adjust the time slice associated with the first virtual machine based on an assessment of time slice adjustment parameters related to an execution time of at least one of the plurality of virtual machines.
