    Nice that they provide a solution for us Piledriver users with PCIE2.0. Does it really work only with a VEGA though? I have a Tonga card and would like to have some proper OpenCL support for it since Clover really needs work. Are there plans to support Tonga too?

      Nice, maybe it would be possible at some point in the future to support older hardware like HD7970 and pre-pcie 3.0 cpus and chipsets.

        Pre-PCIE 3.0 CPUs yes in principle (it involves per-GPU microcode changes among other things) but not HD7970 without major changes since ROCm is built over the HSA hardware features which started getting added in the CI generation (HD7970 is SI).

        That said, the new OpenCL-over-PAL code paths should work fine on SI since they use kernel queues rather than userspace compute queues..

          Previous ROCm drivers (around v.1.4) supported FirePro S9150. I wonder if it would be possible to use this newest ROCm release with S9150?

            ~$ clinfo
            Number of platforms 0



            1.7.2 was working fine.

              Got OpenCL up and running again but on the legacy driver this time. Downloaded AMDGPU-PRO 18.20 Preview and picked the .deb's for the CL driver and it's dependencies and installed with dpkg. Bonus: It works on Debian Sid's 4.16 kernel, unlike ROCm, and only the OpenCL driver was installed so I'm still using Mesa 18.0 from Debian Sid repo for OpenGL.

              Edit:

              Install
              Code:
              sudo dpkg -i amdgpu-core amdgpu-pro-core amdgpu-dkms libdrm2-amdgpu libdrm-amdgpu-amdgpu1 ids-amdgpu clinfo-amdgpu-pro opencl-orca-amdgpu-pro-icd libopencl1-amdgpu-pro opencl-amdgpu-pro opencl-amdgpu-pro-icd
              Code:
              sudo apt-mark auto amdgpu-core amdgpu-pro-core amdgpu-dkms libdrm2-amdgpu libdrm-amdgpu-amdgpu1 ids-amdgpu clinfo-amdgpu-pro opencl-orca-amdgpu-pro-icd libopencl1-amdgpu-pro opencl-amdgpu-pro-icd
              Uninstall
              Code:
              sudo apt autoremove opencl-amdgpu-pro

                Great news!

                Good to see RHEL and CentOS supported!

                I like Ubuntu, but a lot of commercial and research shops in my experience like Redhat or derivatives.

                    I've tried to get the OpenCL driver from ROCm working. I've extracted the required files from the RHEL RPMs. It didn't work because two libraries are missing: libamdocl64.so and libamdocl12cl64.so. Once I copied those from amdgpu-pro, it started to work.
