Abstract

Embodiments described herein include a system, a computer-readable medium and a computer-implemented method for processing a system call (SYSCALL) request. The SYSCALL request from an invisible processing device is stored in a queueing mechanism that is accessible to a visible processing device, where the visible processing device is visible to an operating system and the invisible processing device is invisible to the operating system. The SYSCALL request is processed using the visible processing device, and the invisible processing device is notified using a notification mechanism that the SYSCALL request was processed.
