Building manual

Intro

This documents describes the procedure for compiling Dasharo firmware for QEMU Q35.

Requirements

• Ubuntu 20.04/21.04/22.04 as a host OS was tested
• Internet connection
• Docker installed
  • follow Install Docker Engine on Ubuntu
  • follow Post-installation steps for Linux
• Git, wget, unzip installed

Alternatively Fedora can be used instead of Ubuntu by following the same steps except: Install Docker Engine on Fedora

sudo apt install git unzip wget

Procedure

Obtain Dasharo source code:

Replace the REVISION with one of the:

• qemu_q35_vVERSION (e.g. qemu_q35_v0.1.0) for the given release
• qemu_q35_vVERSION-rcN (e.g. qemu_q35_v0.1.0-rc1) for the given release candidate

Clone Dasharo coreboot fork:

git clone https://github.com/Dasharo/coreboot.git -b REVISION --depth 1

Change directory:

cd coreboot

Compile:

./build.sh qemu

The resulting coreboot image will be placed in the current directory as qemu_q35_<version>.rom.

Initial Deployment

Now you can proceed with initial deployment scenario according to your needs:

• Dasharo initial deployment if you want to use this image for manual testing or everyday use
• Dasharo validation if you want to use binaries for validation purposes
