cd riscv-isa-sim
mkdir build
cd build
../configure --prefix=$RISCV --with-isa=rv64imafdp --with-target=riscv64-unknown-linux-gnu
make -j4
sudo make install

Proxy Kernel

riscv-pk

git clone https://github.com/riscv-software-src/riscv-pk.git
cd riscv-pk

Trick

rvp_intrinsic.h

//CREATE_RVP_INTRINSIC_EMPTY_ARGS (void, clrov)
//CREATE_RVP_INTRINSIC_EMPTY_ARGS (uintXLEN_t, rdov)
