  • Publication number: 20220091847
    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.

  • Publication number: 20220058767
    Abstract: Systems, apparatuses, and methods for enabling indirect chaining of command buffers are disclosed. A system includes at least first and second processors and a memory. The first processor generates a plurality of command buffers and stores the plurality of command buffers in the memory. The first processor also generates and stores, in the memory, a table with entries specifying addresses of the plurality of command buffers and an order in which to process the command buffers. The first processor conveys an indirect buffer packet to the second processor, where the indirect buffer packet specifies a location and a size of the table in the memory. The second processor retrieves an initial entry from the table, processes a first command buffer at the address specified in the initial entry, and then returns to the table for the next entry upon completing processing of the first command buffer.

  • Patent number: 11243799
    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.
