[Buildroot] [PATCH next 1/1] boot/edk2: add support for RISC-V 64bit architecture

[Julien Olivain]

RISC-V 64bit qemu virt machine support has been added in edk2
version "stable202302". See [1].

Since edk2-stable202308, introduced in buildroot in commit 5c9f310
"boot/edk2: bump to version edk2-stable202308", it is now possible
to boot the edk2 UEFI shell in qemu.

This commit adds this early RISC-V support to edk2.

The RISC-V edk2 UEFI shell can be booted in Buildroot with the
following commands:

    # Build EDK2 images
    cat > .config <<EOF
    BR2_riscv=y
    BR2_RISCV_64=y
    BR2_PACKAGE_HOST_QEMU=y
    BR2_PACKAGE_HOST_QEMU_SYSTEM_MODE=y
    BR2_TARGET_EDK2=y
    EOF
    make olddefconfig
    make

    # edk2 image size should fit the 32MB of qemu pflash memories
    truncate -s 32M output/images/RISCV_VIRT_CODE.fd
    truncate -s 32M output/images/RISCV_VIRT_VARS.fd

    # Start qemu:
    output/host/usr/bin/qemu-system-riscv64 \
        -M virt,pflash0=pflash0,pflash1=pflash1,acpi=off \
        -nographic \
        -blockdev node-name=pflash0,driver=file,read-only=on,filename=output/images/RISCV_VIRT_CODE.fd \
        -blockdev node-name=pflash1,driver=file,filename=output/images/RISCV_VIRT_VARS.fd

Note: a Qemu version >= 8.0.0 is needed to properly start edk2. A qemu
version on the host system might now be suffucient. This is why the
Buildroot host-qemu is built in this config example.

Change v1 -> v2:
- Fix 2 typos in the commit log, as reported by Thomas in [2]

Even if Thomas said a v2 was not necessary, I'm resending anyway.
Since this patch was sent few months back, I successfully
rechecked this patch on top of master branch at commit e59346f with
the commands from the commit log.

Also, the recent release of Grub 2.12 in [3] includes many fixes to
allow a full RV64 EFI Linux Kernel boot. This patch will be
necessary to do so. This new grub release is the reason of this v2.

[Yann E. MORIN]

Julien, All,

On 2023-12-22 11:56 +0100, Julien Olivain spake thusly:

Building edk2 for risc-v is broken with per-package directories. For
example, this defconfig fails to build:

    BR2_riscv=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_PER_PACKAGE_DIRECTORIES=y
    BR2_INIT_NONE=y
    BR2_SYSTEM_BIN_SH_NONE=y
    # BR2_PACKAGE_BUSYBOX is not set
    # BR2_PACKAGE_IFUPDOWN_SCRIPTS is not set
    # BR2_TARGET_ROOTFS_TAR is not set
    BR2_TARGET_EDK2=y

The error message is (empty liens elided for brevity):

    Building ... /home/ymorin/dev/buildroot/O/master/build/edk2-edk2-stable202308/MdeModulePkg/Universal/CapsuleRuntimeDxe/CapsuleRuntimeDxe.inf [RISCV64]

     : error 7000: Failed to execute command

    - Failed -

Of course, if one removes the PPD option, the build succeeds. So, it
hints that there is a missing dependency lying around...

I've tried to look around for obvious clues, but apart the fact that it
is failing when running a python script, I did not find anything really
obvious...

Where it gets weirder, though, is that it does work with the docker
image... So, that gives another hint about this python script that is
failing: the docker image is a Debian with python 3.9.2, but my machine
is a Fedora 39 with python 3.12.

Could you have a look, please?

Regards,
Yann E. MORIN.

It seems it is not related to risc-v, finally, as an AArch64 build is
broken similarly;

    BR2_aarch64=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
    BR2_PER_PACKAGE_DIRECTORIES=y
    BR2_INIT_NONE=y
    BR2_SYSTEM_BIN_SH_NONE=y
    # BR2_PACKAGE_BUSYBOX is not set
    # BR2_PACKAGE_IFUPDOWN_SCRIPTS is not set
    # BR2_TARGET_ROOTFS_TAR is not set
    BR2_TARGET_EDK2=y
