.. zephyr:code-sample:: sip_svc
   :name: Arm SiP Services on Intel Agilex SoC FPGA

   Use the SiP SVC subsystem to interact with the Secure Device Manager on Intel Agilex SoC FPGA.

Overview
********

This sample demonstrates the usage of SiP SVC subsystem.This sample
performs a voltage value query from Secure Device Manager in Intel Agilex
SoC FPGA.

Caveats
*******

* SiP SVC subsystem relies on the firmware running in EL3 layer to be in compatible
  with protocol defined inside the SiP SVC subsystem used by the project.
* The sample application relies on the Trusted Firmware ARM firmware in
  intel Agilex SoC FPGA query the voltage levels in Secure Device Manager.

Building and Running
********************
For building the application:

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/sip_svc
   :board: intel_socfpga_agilex_socdk
   :goals: build

For running the application the Zephyr image can be loaded in DDR memory
at address 0x00100000 and ATF BL31 at 0x00001000 from SD Card or QSPI Flash
in ATF BL2.
