Support for RISC-V QEMU virt platform

Overview

RISC-V QEMU 'virt' is a generic platform which does not correspond to any real hardware.

EDK2 for RISC-V virt platform is a payload (S-mode) for the previous stage M-mode firmware like OpenSBI. It follows PEI less design.

The minimum QEMU version required is 8.1 or with commit 7efd65423a which supports separate pflash devices for EDK2 code and variable storage.

Build

export WORKSPACE=`pwd`
export GCC5_RISCV64_PREFIX=riscv64-linux-gnu-
export PACKAGES_PATH=$WORKSPACE/edk2
export EDK_TOOLS_PATH=$WORKSPACE/edk2/BaseTools
source edk2/edksetup.sh
make -C edk2/BaseTools
source edk2/edksetup.sh BaseTools
build -a RISCV64 --buildtarget RELEASE -p OvmfPkg/RiscVVirt/RiscVVirtQemu.dsc -t GCC5

Test

Below example shows how to boot openSUSE Tumbleweed E20.

  1. RISC-V QEMU pflash devices should be of of size 32MiB.

    truncate -s 32M Build/RiscVVirtQemu/RELEASE_GCC5/FV/RISCV_VIRT_CODE.fd

    truncate -s 32M Build/RiscVVirtQemu/RELEASE_GCC5/FV/RISCV_VIRT_VARS.fd

  2. Running QEMU
