5.4.1. Intel® Service Driver
The SMC handler is left resident by ATF and is running at EL3, the highest execution level, therefore it can access the SDM commands. The Intel® Service Driver allows the kernel to execute SMCs in order to access the services offered by the SMC handler.
The default kernel configuration defines CONFIG_INTEL_STRATIX10_SERVICE=y, which means that this driver is part of the kernel. Besides RSU, the Intel® Service Driver also provides other services, such as the FPGA configuration services offered by the ATF SMC handler.
