Abstract: Systems, apparatuses, and methods for implementing a primary input/output (PIO) queue for host and guest operating systems (OS's) are disclosed. A system includes a PIO queue, one or more compute units, and a control unit. The PIO queue is able to store work commands for multiple different types of OS's, including host and guest OS's. The control unit is able to dispatch multiple work commands from multiple OS's to execute concurrently on the compute unit(s). This allows for execution of work commands by different OS's without the processing device(s) having to incur the latency of a world switch.
