1. 文件准备： vortex-tools: 去ssd/lao/ 下面直接复制 vortex-2.2：git clone [email protected]:LY0727/vortex-2.2.git third-party: 去ssd/lao/ 下面直接复制
2. 构建prj cd build ../configure --xlen=64
3. 设置tools目录 build/config.mk ： 设置tools路径
4. make build目录下： make
5. 运行测试 build目录下：./ci/blackbox.sh --driver=opae --app=conv3 --args=-n4

Vortex is a full-stack open-source RISC-V GPGPU.

• Support RISC-V RV32IMAF and RV64IMAFD

  • configurable pipeline issue width.
  • optional local memory, L1, L2, and L3 caches.
• Software:
  • OpenCL 1.2 Support.
• Supported FPGAs:
  • Altera Arria 10
  • Altera Stratix 10
  • Xilinx Alveo U50, U250, U280
  • Xilinx Versal VCK5000

cd build
../configure --xlen=32 --tooldir=$HOME/tools

# should always run before using the toolchain!

• Installing Vortex kernel and runtime libraries to use with external tools requires passing --prefix=<install-path> to the configure script.

../configure --xlen=32 --tooldir=$HOME/tools --prefix=<install-path>
make -s
make install

• Building Vortex 64-bit simply requires using --xlen=64 configure option.

../configure --xlen=32 --tooldir=$HOME/tools

• Sourcing "./ci/toolchain_env.sh" is required everytime you start a new terminal. we recommend adding "source <build-path>/ci/toolchain_env.sh" to your ~/.bashrc file to automate the process at login.

echo "source <build-path>/ci/toolchain_env.sh" >> ~/.bashrc

• Making changes to Makefiles in your source tree or adding new folders will require executing the "configure" script again to get it propagated into your build folder.

../configure

• To debug the GPU, you can generate a "run.log" trace. see /docs/debugging.md for more information.

./ci/blackbox.sh --app=demo --debug=3

• For additional information, check out the /docs.
