Introduction

Jailhouse is a type-1 hypervisor developed by Siemens and released as Open-Source software.

The ERIKA3 RTOS currently supports Jailhouse on the following platforms:

• Nvidia Jetson TX1
• Xilinx ZCU102

Building ERIKA3 for Jailhouse

To build ERIKA3 for Jailhouse, you just need to export the JAILHOUSE_DIR environment variable equal to the directory containing the Jailhouse built objects.
The build process (started by the make command within the generated out directory) will link the ERIKA3 object file to the Jailhouse inmate library.

In case of cross-compilation, you also need to put the cross-compiler in the PATH and set the JAILHOUSE_AARCH64_GCCPREFIX environment variable equal to the cross-compiler prefix.

The build process will create a .bin file. Once Jailhouse has been started, you can:

1. Create the jailhouse cell for ERIKA3:
   sudo jailhouse cell create <cell_file>
2. Load the ERIKA binary file in the cell:
   sudo jailhouse cell load <cell_name> <binary_file>
3. Start ERIKA:
   sudo jailhouse cell start <cell_name>

Please, refer to the platform-specific pages for detailed building instructions.
