16Intel Stratix10 SoC Service Layer
17---------------------------------
18Some features of the Intel Stratix10 SoC require a level of privilege
19higher than the kernel is granted. Such secure features include
20FPGA programming. In terms of the ARMv8 architecture, the kernel runs
21at Exception Level 1 (EL1), access to the features requires
22Exception Level 3 (EL3).
23
24The Intel Stratix10 SoC service layer provides an in kernel API for
25drivers to request access to the secure features. The requests are queued
26and processed one by one. ARM’s SMCCC is used to pass the execution
27of the requests on to a secure monitor (EL3).
