Level zero & gfx snippets

Build

Build dependencies:

• llvm (tested with versions 10, 14, 16)
• SPIRV translator
• level zero headers

Runtime dependencies:

• level zero (NEO runtime driver)
• IGC

All dependencies can be installed with https://github.com/kurapov-peter/gfx_deps

Docker build

docker build .
docker run --network host --privileged -it --name snippets snippets:latest bash

Conda build

First time conda env creation:

conda env create -f scripts/snippets-conda-env.yml
conda activate snippets-dev

Update existing conda env with:

conda env update -f scripts/snippets-conda-env.yml

cmake -Bbuild -GNinja .
cmake --build build

Check gpu availability via L0

Compile manually:
g++ gpu_discover.cpp -L/path/to/libze_loader/dir -Wl,-rpath=/path/to/libze_loader/dir -lze_loader

Cmake:
mkdir build && cd build
cmake ..
PATH=/path/to/llvm-spirv:$PATH make -jnproc

Code generated spirv execution

./ll_gen  // would generate gen.bc  
llvm-spirv gen.bc -o gen.spv  
./simple_kernel_run gen.spv

Generated spirv execution

./spv_gen  // would generate spv_gen.spv  
./simple_kernel_run spv_gen.spv

Complete flow

./complete  // generates spirv in memory and runs it with similar to host.cpp code
