Base Boot Requirements - Architecture Compliance Suite

BBR specification complements the BSA specification by defining the base firmware requirements required for out-of-box support of any BSA compatible operating system or hypervisor. These requirements are comprehensive enough to enable booting multi-core ARM platforms while remaining minimal enough to allow for OEM and ODM innovation, and market differentiation.

For more information, see BBR specification.

The BBR test suites check for compliance against the SBBR/EBBR specification. The BBR tests are delivered through:

• UEFI Self Certification Tests (SCT)
• Firmware Test Suite (FWTS)

Release details

• Code Quality: v0.8 Beta-0
• The BBR tests are written for version 1.0 of the BBR specification.
• The compliance suite is not a substitute for design verification.
• To review the ACS logs, Arm licensees can contact Arm directly through their partner managers

Building BBR

BBR is automatically built and packaged into ACS, but it can also be built independently.

1. Get BBR repository

`git clone https://github.com/ARM-software/bbr-acs.git` 

2. Getting the required Source codes and Tools

navigate to the bbr-acs/<ebbr/sbbr>/scripts directory

get source by running the ./build-scripts/get_<ebbr/sbbr>_source.sh

This will download edk2-test, edk2, fwts and tools

3. Building ACS for SBBR & EBBR

run ./build-scripts/build_<ebbr/sbbr>.sh to build BBR ACS components, SCT and FWTS.

The script will apply patches to create a "EBBR or SBBR" build recipe in the SCT/FWTS build system.

The the binaries of SCT are generated here bbr-acs/<ebbr/sbbr>/scripts/edk2-test/uefi-sct/<ARCH>_SCT #(i.e. AARCH64_SCT)

The the binaries of FWTS are generated here bbr-acs/<ebbr/sbbr>/scripts/fwts/fwts_output

UEFI Self Certification Tests

Self-Certification Tests (SCT) test the UEFI implementation requirements defined by SBBR/EBBR.

Prerequisite : Ensure that the system time is correct before starting SCT tests.

Running SCT

BBR SCT tests are built as part of the test suite

Running of BBR SCT tests is now automated. You can choose to skip the automated SCT tests by pressing any key when the UEFI shell prompts.

• Shell>Press any key to stop the EFI SCT running

To run SCT manually, Follow these steps:

1. Shell>FS(X):

• FS(X):>cd EFI\BOOT\bbr\SCT
• To run EBBR or SBBR tests FS(X):EFI\BOOT\bbr\SCT>SCT -s <ebbr.seq/sbbr.seq>
• To run all tests FS(X):EFI\BOOT\bbr\SCT>SCT -a -v

The User can also select and run tests individually. For information about running the tests, see SCT User Guide.

Firmware Test Suite

Firmware Test Suite (FWTS) is a package that is hosted by Canonical. FWTS provides tests for ACPI, SMBIOS and UEFI. Several SBBR assertions are tested though FWTS.

Running FWTS tests

You can choose to boot Linux OS from UEFI by entering the command:

Shell>exit

This command loads the grub menu. Press enter to choose the option 'Linux BusyBox' that boots the OS and runs FWTS tests and OS context BSA tests automatically.

Logs are stored into the a results partition, which can be viewed on any machine after tests are run.
