This section describes how you can build and run TF-A with RME enabled.
We assume you have all the :ref:`Prerequisites` to build TF-A.
-To enable RME, you need to set the ENABLE_RME build flag when building
-TF-A. Currently, this feature is only supported for the FVP platform.
-
The following instructions show you how to build and run TF-A with RME
-for two scenarios: TF-A with TF-A Tests, and four-world execution with
-Hafnium and TF-A Tests. The instructions assume you have already obtained
-TF-A. You can use the following command to clone TF-A.
+for two scenarios:
-.. code:: shell
+- Three-world execution: TF-A with TF-A Tests or Linux.
- git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
+ - NS (TF-A Test or Linux),
+ - Root (TF-A)
+ - Realm (RMM or TRP)
+
+- Four-world execution: TF-A, Hafnium and TF-A Tests or Linux.
+
+ - NS (TF-A Test or Linux),
+ - Root (TF-A)
+ - Realm (RMM or TRP)
+ - SPM (Hafnium)
To run the tests, you need an FVP model. Please use the :ref:`latest version
<Arm Fixed Virtual Platforms (FVP)>` of *FVP_Base_RevC-2xAEMvA* model.
-.. note::
+Three World Testing with TF-A Tests
+*************************************
- ENABLE_RME build option is currently experimental.
+**1. Obtain and build TF-A Tests with Realm Payload**
+
+The full set of instructions to setup build host and build options for
+TF-A-Tests can be found in the `TFTF Getting Started`_.
-Building TF-A with TF-A Tests
-********************************************
Use the following instructions to build TF-A with `TF-A Tests`_ as the
non-secure payload (BL33).
-**1. Obtain and build TF-A Tests**
-
.. code:: shell
git clone https://git.trustedfirmware.org/TF-A/tf-a-tests.git
cd tf-a-tests
- make CROSS_COMPILE=aarch64-none-elf- PLAT=fvp DEBUG=1
+ make CROSS_COMPILE=aarch64-none-elf- PLAT=fvp DEBUG=1 all pack_realm
-This produces a TF-A Tests binary (*tftf.bin*) in the *build/fvp/debug* directory.
+This produces a TF-A Tests binary (**tftf.bin**) with Realm payload packaged
+and **sp_layout.json** in the **build/fvp/debug** directory.
-**2. Build TF-A**
+**2. Obtain and build RMM Image**
+
+Please refer to the `RMM Getting Started`_ on how to setup
+Host Environment and build RMM.
+
+The below command shows how to build RMM using the default build options for FVP.
.. code:: shell
+ git clone --recursive https://git.trustedfirmware.org/TF-RMM/tf-rmm.git
+ cd tf-rmm
+ cmake -DRMM_CONFIG=fvp_defcfg -S . -B build
+ cmake --build build
+
+This will generate **rmm.img** in **build** folder.
+
+**3. Build TF-A**
+
+The `TF-A Getting Started`_ has the necessary instructions to setup Host
+machine and build TF-A.
+
+To build for RME, set ``ENABLE_RME`` build option to 1 and provide the path to
+the RMM binary using the ``RMM`` build option.
+Currently, this feature is only supported for the FVP platform.
+
+.. note::
+
+ ENABLE_RME build option is currently experimental.
+
+If the ``RMM`` option is not used, then the Test Realm Payload (TRP) in TF-A
+will be built and used as the RMM.
+
+.. code:: shell
+
+ git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
cd trusted-firmware-a
make CROSS_COMPILE=aarch64-none-elf- \
PLAT=fvp \
ENABLE_RME=1 \
+ RMM=<path/to/rmm.img> \
FVP_HW_CONFIG_DTS=fdts/fvp-base-gicv3-psci-1t.dts \
DEBUG=1 \
BL33=<path/to/tftf.bin> \
all fip
-This produces *bl1.bin* and *fip.bin* binaries in the *build/fvp/debug* directory.
-The above command also builds TRP. The TRP binary is packaged in *fip.bin*.
+This produces **bl1.bin** and **fip.bin** binaries in the **build/fvp/debug** directory.
+
+Running the tests for a 3 world FVP setup
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Use the following command to run the tests on FVP. TF-A Tests should boot
+and run the default tests including Realm world tests.

+Building TF-A with RME enabled Linux Kernel
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If an RME enabled Linux kernel and filesystem is available for testing,
+and a suitable NS boot loader is not available, then this option can be used to
+launch kernel directly after BL31:
+
+.. code-block:: shell
+
+ cd trusted-firmware-a
+ make CROSS_COMPILE=aarch64-none-elf- \
+ PLAT=fvp \
+ ENABLE_RME=1 \
+ RMM=<path/to/rmm.img> \
+ FVP_HW_CONFIG_DTS=fdts/fvp-base-gicv3-psci-1t.dts \
+ DEBUG=1 \
+ ARM_LINUX_KERNEL_AS_BL33=1 \
+ PRELOADED_BL33_BASE=0x84000000 \
+ all fip
+
+Boot and run the RME enabled Linux Kernel
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Use the following additional arguments to boot the kernel on FVP.
+
+.. code-block:: shell
+
+ --data cluster0.cpu0=<path_to_kernel_Image>@0x84000000 \
+ -C bp.virtioblockdevice.image_path=<path_to_rootfs.ext4>
+
+.. tip::
+
+ Set the FVP option `cache_state_modelled=0` to run Linux based tests much faster.
Four-world execution with Hafnium and TF-A Tests

+*************************************************
+
+Four-world execution involves software components in each security state: root,
secure, realm and non-secure. This section describes how to build TF-A
-with four-world support. We use TF-A as the root firmware, `Hafnium`_ as the
-secure component, TRP as the realm-world firmware and TF-A Tests as the
-non-secure payload.

-Before building TF-A, you first need to build the other software components.
-You can find instructions on how to get and build TF-A Tests above.
+We use TF-A as the root firmware, `Hafnium SPM`_ is the reference Secure world component
+and the software components for the other 2 worlds (Realm and Non-Secure)
