  To: buildroot; +Cc: Mikael Bourhis-Cloarec, Romain Naour, Adam Duskett

From: Adam Duskett <Aduskett@gmail.com>

Buildroot currently has all of the needed packages to use Mender as the primary
update system. However, there isn't any documentation or examples now that
provide a starting point for users. This lack of documentation makes setting up
a Mender based update system difficult and time-consuming.

Provided in this patch series is a mender_x86_64_efi_defconfig of which sets up
an x86_64 EFI based build that is ready to flash to a USB pen drive or use in a
QEMU environment. The system partition schema comprises of two equally sized
root partitions and a data partition that mounts to /var/lib/mender as a
persistent data store partition.

There is a board/mender/readme.txt provided, which gives users documentation on
how to flash the built image or boot the image using QEMU as well.

The post-build and post-image-efi scripts also have four options:
-a --artifact-name:
  - The name of the artifact, this is added to /etc/mender/artifact_info
-o --data-part-size:
  - The data partition size.
-d --device-type
  - The device-type used by mender to catagorize registered devices.
-g --generate-mender-image
  - Set to true to generate a mender image after a build.

[Romain: rebase on master (01.2022)
  - update genimage-efi.cfg to use GPT partition table and genimage-15 syntax
  - bump the kernel to 5.15.13
  - Add host-libelf kernel dependency
  - Use BR2_TARGET_GRUB2_BUILTIN_MODULES_EFI after commit 82d1e8c628cc
    (boot/grub2: use none platform when building for host)
  - Add regexp grub mandatory module for mender-grubenv
  - remove startup.nsh from genimage-efi.cfg after commit 3efb5e31fc05
    (board, boot, package: remove usage of startup.nsh in EFI partition)]

Changes: v5 -> v6:
  - rebase on master (01.2022)
  - update genimage-efi.cfg to use GPT partition table and genimage-15 syntax
  - bump the kernel to 5.15.13
  - Add host-libelf kernel dependency
  - Use BR2_TARGET_GRUB2_BUILTIN_MODULES_EFI after commit 82d1e8c628cc
    (boot/grub2: use none platform when building for host)
  - Add regexp grub mandatory module for mender-grubenv
  - remove startup.nsh from genimage-efi.cfg after commit 3efb5e31fc05
    (board, boot, package: remove usage of startup.nsh in EFI partition)

Changes v4 -> v5:
  - Fix the patch format

Changes v3 -> v4 (Mikael Bourhis-Cloarec):
  - Add fix: missing "=y" for SSP option in defconfig
  - Add fix: mounting point of '/dev/vda1' in 'overlay/etc/fstab'

Changes v2 -> v3:
  - Bump kernel version to 5.5.7
  - Move the board files form board/mender to board/mender/x86_64
  - Add the four arguments to the post-build and post-image scripts.
  - Update genimage-efi.cfg to ensure that all partitions line up properly.
  - Update the readme.txt file to reflect the script argument changes.

Changes v1 -> v2:
  - Remove uneeded entries in board/mender/overlays/etc/fstab

  - Rename post-image-efi-gpt.sh to post-image-efi.sh

  - Rename pre-image.sh to post-build.sh to keep with standard naming conventions.

  - Check if /var/lib/mender is a symlink, and if so; remove it and create a
    directory in its place. This change prevents the mender init script from
    doing the same thing and preventing the data partition from mounting
    correctly on the initial boot.

  - Make creating a mender artifact optional after the build.

  - Add more documentation in board/mender/readme.txt.
  - Add genimage-efi.cfg [Thomas]

  - Use genimage.sh instead of the old-style found in
    board/pc/post-image-efi-gpt.sh (Thomas)

+Mender UEFI PC sample config
+=====================
+
+1. Build
+
+  $ make mender_x86_64_efi_defconfig
+
+  Add any additional packages required and build:
+
+  $ make
+
+2. Write the Pendrive
+
+  The build process will create a Pendrive image called disk.img in
+  output/images.
+
+  Write the image to a pendrive:
+
+  $ dd if=output/images/disk.img of=/dev/${pendrive}; sync
+
+  Once the process is complete, insert it into the target PC and boot.
+
+  Remember that if said PC has another boot device you might need to
+  select this alternative for it to boot.
+
+  You might need to disable Secure Boot from the setup as well.
+
+3. Enjoy
+
+Emulation in qemu
+========================
+
+Run the emulation with:
+
+qemu-system-x86_64 \
+    -M pc \
+    -bios </path/to/OVMF_CODE.fd> \
+    -drive file=output/images/disk.img,if=virtio,format=raw \
+    -net nic,model=virtio \
+    -net user
+
+Note that </path/to/OVMF.fd> needs to point to a valid x86_64 UEFI
+firmware image for qemu. It may be provided by your distribution as an
+edk2 or OVMF package, in a path such as /usr/share/edk2/ovmf/OVMF_CODE.fd.
+
+Optional arguments:
+ - -enable-kvm to speed up qemu. This requires a loaded kvm module on the host
+    system.
+ - Add -smp N to emulate an SMP system with N CPUs.
+
+The login prompt will appear in the serial window.
+
+Tested with QEMU 4.1.1 on Fedora 31
+
+Creating a mender-artifact
+========================
+In menuconfig -> System configuration, edit the field
+"Extra arguments passed to custom scripts"
+And change --generate-mender-image=false to --generate-mender-image=true
+
+You may wish to change --artifact-name=1.0 to a name that best suits your
+particular needs, as this option changes the mender artifact name.
+
+Using mender
+========================
+Please read the mender documentation at:
+https://docs.mender.io/2.2/getting-started
