vpykhtin 51cc9c2f8c SWDEV-1 - OpenCL binary substituion feature based on source program text hash matching.
This patch allows to substitute binary for the opencl program. It supposed to be used as:

1. Run the opencl program with -save-temps.

2. Open the cl temp and find the following text in the program header:
    Hash to override:
	Source: 0xd66bcfa20e69e605
	Source + clang options: 0x656a9dd8aedcbfb6

3. Create config file (ascii text) with a pair(s):

    <hash> <path_to_binary_to_substitute>

    where hash is the hex value from step 2 (without leading 0x), you can use either hash
    depending on what you're going to match:
	only the source text of the program or along with it's clang options.

4. Set the env variable AMD_OCL_SUBST_OBJFILE to the path of your config file.

5. Rerun the opencl program.

ROCclr - Radeon Open Compute Common Language Runtime

ROCclr is a virtual device interface that compute runtimes interact with to different backends such as ROCr or PAL This abstraction allows runtimes to work on Windows as well as on Linux without much effort.

Repository branches

The repository maintains several branches. The branches that are of importance are:

  • Main branch: This is the stable branch. It is up to date with the latest release branch, for example, if the latest ROCM release is rocm-4.1.x, main branch will be the repository based on this release.
  • Develop branch: This is the default branch, on which the new features are still under development and visible. While this maybe of interest to many, it should be noted that this branch and the features under development might not be stable.
  • Release branches. These are branches corresponding to each ROCM release, listed with release tags, such as rocm-4.0.x, rocm-4.1.x, etc.

Building

Prerequisites

Getting the source code

git clone -b main https://github.com/ROCm-Developer-Tools/ROCclr.git
git clone -b main https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime.git

Set the environment variables

export ROCclr_DIR="$(readlink -f ROCclr)"
export OPENCL_DIR="$(readlink -f ROCm-OpenCL-Runtime)"

Build ROCclr

Here is command to build ROCclr:

cd "$ROCclr_DIR"
mkdir -p build; cd build
cmake -DOPENCL_DIR="$OPENCL_DIR" -DCMAKE_INSTALL_PREFIX=/opt/rocm/rocclr ..
make -j$(nproc)
sudo make install

Optional steps to build HIP runtime

Enter the directory where git cloned the ROCClr and OpenCL. Run the following commands:

git clone -b main https://github.com/ROCm-Developer-Tools/HIP.git
export HIP_DIR="$(readlink -f HIP)"
cd "$HIP_DIR"
mkdir -p build; cd build
cmake -DCMAKE_PREFIX_PATH="$ROCclr_DIR/build;/opt/rocm/" ..
make -j$(nproc)

Release build

For release build, add "-DCMAKE_BUILD_TYPE=Release" to the cmake command line.
