Release 2 - SMP

BSP Support

The fvp-baser-aemv8r64 Yocto MACHINE supports the following BSP components, where either a standard or Real-Time Linux kernel (PREEMPT_RT) can be built and run:

boot-wrapper-aarch64: provides PSCI support
Linux kernel: linux-yocto-5.10
Linux kernel with PREEMPT_RT support: linux-yocto-rt-5.10

Note that the Real-Time Linux kernel (PREEMPT_RT) does not use the real-time architectural extensions of the Armv8-R feature set.

Quick start: How to Build and Run

Host environment setup

The following instructions have been tested on hosts running Ubuntu 18.04 and Ubuntu 20.04.

Install the required packages for the build host:

https://docs.yoctoproject.org/singleindex.html#required-packages-for-the-build-host

Install the kas setup tool for bitbake based projects:

$ pip3 install --user kas

For more details on kas, see https://kas.readthedocs.io/

To build the images for fvp-base machine, you also need to:

Download the FVP_Base_AEMv8R_11.15_14.tgz image AEM V8-R FVP Installer (Linux) package from Arm's website . You need to have an account and be logged in to be able to download it.
Set absolute path to the FVP_Base_AEMv8R_11.15_14.tgz downloaded package in FVP_BASE_R_AEM_TARBALL_URI
Accept EULA in FVP_BASE_R_ARM_EULA_ACCEPT

The variables should be set like so:

$ FVP_BASE_R_AEM_TARBALL_URI="file:///absolute/path/to/FVP_Base_AEMv8R_11.15_14.tgz"
$ FVP_BASE_R_ARM_EULA_ACCEPT="True"

Note: The host machine should have at least 50 GBytes of free disk space for the next steps to work correctly.

Fetch sources

Fetch the meta-arm repository into a build directory:

$ mkdir -p ~/fvp-baser-aemv8r64-build
$ cd ~/fvp-baser-aemv8r64-build
$ git clone https://git.yoctoproject.org/git/meta-arm

Build

Building with the standard Linux kernel:

$ cd ~/fvp-baser-aemv8r64-build
$ export FVP_BASE_R_AEM_TARBALL_URI="file:///absolute/path/to/FVP_Base_AEMv8R_11.15_14.tgz"
$ export FVP_BASE_R_ARM_EULA_ACCEPT="True"
$ kas build meta-arm/kas/fvp-baser-aemv8r64-bsp.yml
