Intel FPGA SoC is composed of ARM Cortex hard processor system (HPS) and Secure Device Manager (SDM). SDM is the hardware which does FPGA configuration, remote system update (RSU), crypto service (FCS), warm reset and other features. To meet the whole system security needs and support virtual machine requesting communication with SDM, only the secure world of software (EL3) can interfaces with SDM. All software entities running on the other exception level must channel through the EL3 software whenever it needs service from SDM. Intel Stratix 10 service layer driver, added into Opensource kernel mainlines since version 5.0, interfaces with the service provides at EL1 (FPGA manager, RSU and FPGA crypto service drivers as today) and managers secure monitor call (SMC) to communicate with the secure monitor software at the secure world (EL3).
