AMD AIE Plugin for IREE

This repository contains an early-phase IREE compiler and runtime plugin for interfacing the AMD AIE accelerator to IREE.

Architectural Overview

Developer Setup

These instructions assume that you have an appropriate IREE checkout side by side with this repository have an IREE build setup in an iree-build directory that is also a sibling. This is not a requirement, but instructions will need to be changed for different paths.

Preparing repository:

git submodule update --init

Enabling in IREE

To pin IREE and its submodules (LLVM, etc) to commits which are compatible with this plugin, run

python3 sync_deps.py

from within the iree-amd-aie root directory. Then,

cd ../iree-build
cmake -DIREE_CMAKE_PLUGIN_PATHS=../iree-amd-aie .
ninja

to build IREE with amd-aie plugin. Note for the time being building the amd-aie backend requires headers-only Boost library. On Ubuntu you can do this with

sudo apt-get install libboost-dev

Lit tests specific to AIE can be run with something like:

ctest -R amd-aie

Runtime driver setup

To enable the runtime driver. You need to make sure XRT cmake package is discoverable by cmake. One option is to add it to your PATH. Note that with a standard setup, XRT is installed in /opt/xilinx/xrt.

Now from within the iree-amd-aie root directory. Then,

cd ../iree-build
cmake . -DIREE_CMAKE_PLUGIN_PATHS=../iree-amd-aie \
  -DIREE_EXTERNAL_HAL_DRIVERS=xrt \
  -DXRT_DIR=/opt/xilinx/xrt/share/cmake/XRT
ninja

Building XRT

For the CI, we prefer to build against the pinned XRT. Note that XRT has submodules so recursively submodule initialization is required.

You can build using the same script the CI does:

./build_tools/ci/build_xrt.sh ../xrt-build ../xrt-install

Then instead of using the default system install location for -DXRT_DIR= above, prepend the ../xrt-install/ prefix for the one you just built.

Ubuntu Dependencies

Presently XRT is a monolithic build that unconditionally requires a number of packages. Here are the requirements for various operating systems:

apt install \
  libboost-dev libboost-filesystem-dev libboost-program-options-dev \
  libboost-system-dev \
  pkg-config libdrm-dev opencl-headers ocl-icd-opencl-dev libssl-dev \
  rapidjson-dev \
  protobuf-compiler \
  libprotobuf-dev \
  python3-pybind11 \
  uuid-dev \
  libcurl4-openssl-dev \
  libudev-dev \
  systemtap-sdt-dev \
  libelf-dev
