Hi Jiewen, We currently only use below modules from ArmVirtPkg, - ArmVirtPkg/Library
o FdtPciPcdProducerLib o FdtPciHostBridgeLib - ArmVirtPkg/ o VirtioFdtDxe o FdtClientDxe o HighMemDxe Above modules are related to the extraction of the platform configuration from FDT. We also use ArmPkg/DriverArmPciCpuIoDxe, we can have RISC-V instance of CpuIoDxe but still leverage PCD produced by FdtPciPcdProducerLib. Another library is QemuFwCfgLib from ArmVirtPkg/Library, I think we can have RISC-V own instance because there is a one instance under OvmfPkg already.

To have those modules under OvmfPkg also makes sense to me. See how others think of this.

I prefer to move them into OvmfPkg. Now, ArmVirtPkg also includes the modules from OvmfPkg. I also include OVMF package maintainers for this discussion.

First at all, we would like to create a folder RiscvVirtPkg under edk2 repo and integrated in the Platform CI build. Second, RISC-V edk2 OVMF package leverages some edk2 libraries and drivers from ArmVirtPkg, such as FDT related modules for PCI bus, host bridge and etc. We would like to move those generic virtual drivers to a common folder for ARM and RISC-V (I don’t think this way is necessary though). Or can we move those to just under OvmfPkg because OvmfPkg also provides some common drivers for the processor architectures. Thoughts?
