The deployment architecture is shown as the following figure:

First, clone this repository to your local:

git clone https://github.com/YEWPO/y-cca.git

All dependencies list in scripts/init.sh, you can edit it when necessary.

Download dependencies by execute:

make init

Build all dependencies by execute (If you modified the codes, re-run this command is necessary):

make build

By default, the RMM version is v1.0. To build RMM v1.1, execute:

make build RMM_V1_1=ON

🚀 Launching System and Realm Guest

Run the CCA system by execute:

make run

We created scripts for QEMU and LKVM to launch Realm Guest, you can use it to launch guest.

Launching Realm Guest by QEMU (❗ Do not support Planes Feature currently):

/mnt/scripts/qemu_realm.sh

Launching Realm Guest by LKVM:

/mnt/scripts/lkvm_realm.sh

In order to debug the exception simply, you can modify the lkvm_realm.sh script to change the -c 2 to -c 1.

🔗 Code Base

• Our RMM based on Linaro RMM, branch cca/v4.
• Our Linux based on Linaro linux-cca, branch cca-full/v5+v7.
