0022 Intel Stratix10 SoC Service Layer
0023 ---------------------------------
0024 Some features of the Intel Stratix10 SoC require a level of privilege
0025 higher than the kernel is granted. Such secure features include
0026 FPGA programming. In terms of the ARMv8 architecture, the kernel runs
0027 at Exception Level 1 (EL1), access to the features requires
0028 Exception Level 3 (EL3).
0029
0030 The Intel Stratix10 SoC service layer provides an in kernel API for
0031 drivers to request access to the secure features. The requests are queued
0032 and processed one by one. ARM’s SMCCC is used to pass the execution
0033 of the requests on to a secure monitor (EL3).
