@paveltc @kiritigowda For now, a very simple CI setup that I currently have on my fork (to just run checks before I PR into GPUopen) is 4 different workflows (for host/ocl/hiprtc/hip static) running on a docker on a self-hosted server. (Each just runs respective build followed by performancetests) https://github.com/r-abishek/rpp/actions

closing this issue and creating a new one to add tests into CI
