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).
