US Patent 10503551 Coordinating FPGA services using cascaded FPGA service managers

An information handling system may include a field-programmable gate array (FPGA), and a hypervisor to manage virtual machines. The hypervisor may host a first FPGA service manager that loads instances of binary images for FPGA services into respective regions of the FPGA for the benefit of software applications. The virtual machine may host a second FPGA service manager that receives a request for an FPGA service from a software application running in the virtual machine, and sends a query to the first FPGA service manager to determine whether a binary image for the FPGA service exists on the FPGA. The first FPGA service manager may receive the query and, if a binary image instance for the FPGA service exists on the FPGA, may provide information to the second FPGA service manager to facilitate the use of the FPGA service by the software application running in the virtual machine.
