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). .. kernel-doc:: include/linux/firmware/intel/stratix10-svc-client.h :functions: stratix10_svc_command_code .. kernel-doc:: include/linux/firmware/intel/stratix10-svc-client.h :functions: stratix10_svc_client_msg .. kernel-doc:: include/linux/firmware/intel/stratix10-svc-client.h :functions: stratix10_svc_command_config_type .. kernel-doc:: include/linux/firmware/intel/stratix10-svc-client.h :functions: stratix10_svc_cb_data .. kernel-doc:: include/linux/firmware/intel/stratix10-svc-client.h :functions: stratix10_svc_client .. kernel-doc:: drivers/firmware/stratix10-svc.c :export: |
