Since the majority of the Hostcall implementation now sits in the commmon layer, the PAL backend simply just needs to invoke it. One thing that is missing though is HSA signal support. The newly added pal::Signal class is a light emulaion of what HSA signals provide. The current implementation is just enough to get Hostcall working, but it can be expanded in the future if needed to fully emulate HSA signals. The major difference for now between PAL and ROCm hostcall implemenations is that PAL doesn't support blocking signals. This will be enabled in the near future. For now use active wait for PAL.

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.
- 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
- Install mesa-common-dev
- Either build or install COMGR, CLANG and Device Library
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.
