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