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