ROCt Library

This repository includes the user-mode API interfaces used to interact with the ROCk driver.

Starting at 1.7 release, ROCt uses drm render device. This requires the user to belong to video group. Add the user account to video group with "sudo usermod -a -G video username" command if the user if not part of video group yet. NOTE: Users of Ubuntu 20.04 will need to add the user to the new "render" group, as Ubuntu has changed the owner:group of /dev/kfd to render:render as of that release

ROCk Driver

The ROCt library is not a standalone product and requires that you have the correct ROCk driver set installed. We recommend reading the full compatibility and installation details which are available in the ROCk github:

Building the Thunk

A simple cmake-based system is available for building thunk. To build the thunk from the the ROCT-Thunk-Interface directory, execute:

    mkdir -p build
    cd build
    cmake ..
    make

If the hsakmt-roct and hsakmt-roct-dev packages are desired:

    mkdir -p build
    cd build
    cmake ..
    make package

If you choose not to build and install packages, manual installation of the binaries and header files can be done via:

    make install

NOTE: For older versions of the thunk where hsakmt-dev.txt is present, "make package-dev" and "make install-dev" are required to generate/install the developer packages. Currently, these are created via the "make package" and "make install" commands
