Setting up RISCV Qemu VM:¶

Qemu Installation:¶

./configure --enable-virtfs --enable-slirp --target-list=riscv64-softmmu --prefix=[dir-name] make make install

Prebuild Linux Kernel and disk image can be downloaded from https://fedoraproject.org/wiki/Architectures/RISC-V/Installing Local image at pcl-epyc01 is availble at /home/raisiddh/tools/riscv-vm

Once qemu is installed, use the following command to start the VM:

${QEMU_INSTALLDIR}/qemu-system-riscv64 \ -machine virt \ -smp 4 \ -m 4G \ -cpu rv64,v=true,vlen=512,elen=64,vext_spec=v1.0\ -virtfs local,path=shared_folder,mount_tag=host0,security_model=passthrough,id=host0 \ -kernel fw_payload-uboot-qemu-virt-smode.bin -nographic\ -object rng-random,filename=/dev/urandom,id=rng0 \ -device virtio-rng-device,rng=rng0 \ -device virtio-blk-device,drive=hd0 \ -drive file=Fedora-Developer-Rawhide-20210421.n.0-sda.raw,format=raw,id=hd0\ -device virtio-net-device,netdev=usernet \ -netdev user,id=usernet,hostfwd=tcp::10000-:22

Host ~Shared folder in the VM can be mounted using sudo mount -t 9p -o trans=virtio host0 shared_folder -oversion=9p2000.L command

Emulate RVV instructino using BSC Vehave:¶

Download prebuild vehave binary from [1] and untar binary in $VHAVE_INSTALL_PATH.

Usage: $(VEHAVE\_INSTALL\_PATH)/bin/vehave [command line]
