You can build the Jailhouse inmate and link it to the ERIKA Enterprise,
either for Cortex-A or for x86-64.
What is not currently supported by the Jailhouse build system is the
possibility of using different toolchains for the hypervisor firmware and
the inmate library.
This is useful in case you want to use a bare-metal toolchain with libc
(e.g. newlib) for the inmate.
Indeed, we have successfully used a bare-metal toolchain by Linaro (with
libc) in the inmate. We have been able of even using dynamic memory
allocation and C++ data structures.
You can easily patch Jailhouse's makefiles for using different compilers
for the hypervisor firmware and the inmate library (which could eventually
be linked to the ERIKA RTOS, in case of need).
Best regards,
Claudio
