|
| ## Build llama.cpp locally (for riscv64) |
|
|
| 1. Prepare Toolchain For RISCV |
| ~~~ |
| wget https://archive.spacemit.com/toolchain/spacemit-toolchain-linux-glibc-x86_64-v1.1.2.tar.xz |
| ~~~ |
|
|
| 2. Build |
| Below is the build script: it requires utilizing RISC-V vector instructions for acceleration. Ensure the `GGML_CPU_RISCV64_SPACEMIT` compilation option is enabled. The currently supported optimization version is `RISCV64_SPACEMIT_IME1`, corresponding to the `RISCV64_SPACEMIT_IME_SPEC` compilation option. Compiler configurations are defined in the `riscv64-spacemit-linux-gnu-gcc.cmake` file. Please ensure you have installed the RISC-V compiler and set the environment variable via `export RISCV_ROOT_PATH={your_compiler_path}`. |
| ```bash |
| |
| cmake -B build \ |
| -DCMAKE_BUILD_TYPE=Release \ |
| -DGGML_CPU_RISCV64_SPACEMIT=ON \ |
| -DLLAMA_OPENSSL=OFF \ |
| -DGGML_RVV=ON \ |
| -DGGML_RV_ZFH=ON \ |
| -DGGML_RV_ZICBOP=ON \ |
| -DGGML_RV_ZIHINTPAUSE=ON \ |
| -DRISCV64_SPACEMIT_IME_SPEC=RISCV64_SPACEMIT_IME1 \ |
| -DCMAKE_TOOLCHAIN_FILE=${PWD}/cmake/riscv64-spacemit-linux-gnu-gcc.cmake \ |
| -DCMAKE_INSTALL_PREFIX=build/installed |
| |
| cmake --build build --parallel $(nproc) --config Release |
| |
| pushd build |
| make install |
| popd |
| ``` |
|
|
| ## Simulation |
| You can use QEMU to perform emulation on non-RISC-V architectures. |
|
|
| 1. Download QEMU |
| ~~~ |
| wget https://archive.spacemit.com/spacemit-ai/qemu/jdsk-qemu-v0.0.14.tar.gz |
| ~~~ |
|
|
| 2. Run Simulation |
| After build your llama.cpp, you can run the executable file via QEMU for simulation, for example: |
| ~~~ |
| export QEMU_ROOT_PATH={your QEMU file path} |
| export RISCV_ROOT_PATH_IME1={your RISC-V compiler path} |
| |
| ${QEMU_ROOT_PATH}/bin/qemu-riscv64 -L ${RISCV_ROOT_PATH_IME1}/sysroot -cpu max,vlen=256,elen=64,vext_spec=v1.0 ${PWD}/build/bin/llama-cli -m ${PWD}/models/Qwen2.5-0.5B-Instruct-Q4_0.gguf -t 1 |
