| 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). | |
