    Phoronix: AMD's ROCm 1.4 Now Available With OpenCL Support

    The Radeon Open Compute platform has been updated and quietly released prior to the weekend. The ROCm 1.4 release comes with preliminary OpenCL support...

    It still needs closed source components ---> useless.

      So, leave that alone for a moment, it requires PCI-e atomics, which apparently only exist in certain Xeons, certain v3 Core series, and only Ryzen and Naples AMD CPUs, which haven't been released yet at the time of this post. So, if you don't have a Broadwell-based server chip, or aren't in AMD or Cavium's inner circle testing the chips, this isn't going to work.

        Hopefully AMD will make amdgpu-pro available via packages.amd.com someday.

          It was advertised as a closed-source developer preview running in parallel with the remaining open sourcing effort. How does that make it useless ?

            It's useless unless you use the sanctioned Ubuntu 4.7 blessed Kernel and a few other tag along options which I know no one who is going to rebuild a system [outside of Phoronix whose livelihood seems to be a perpetual state of testing] to use AMDGPU-Pro.

            Seeing as OpenCL is broken on the Mesa stack and libclc [having tested LLVM 3.9.1 and Debian rebuilt Mesa] against Blender 2.78a and Luxrender 1.6 with the following erroneous error that Debian refuses to test further. The work Stellar did to add those 2 lousy lines of Code to recognize Polaris based GPGPUs was for naught with libclc throwing errors: a project Mesa depends on and has been languishing since mid September 2016.

            For reference the version of libclc in use: libclc-amdgcn (0.2.0+git20160907-3)

            Pardon the long dump of info:

            I am hardly convinced that ROCm will `just work' with the FOSS status currently hosed.

              Does the new version of rocm handle newer Linux kernel?
              Has it been tested on hybrid laptop i.e. AMD Radeon M265DX?
              Edit: I decide to install rocm anyway and encounter this issue while following the instruction

              Code:
              $ sudo dnf install rocm --allowerasing
              Last metadata expiration check: 0:00:42 ago on Mon Dec 19 09:32:16 2016.
              Error: package rocm-1.4.0-0.x86_64 requires rocm-kernel = 1.4.0, but none of the providers can be installed
              It looks like rocm-kernel is missing.

                They said this is available on all Haswell+ CPU (except lower-end, like Pentium and Celeron).

                Anyway, this is useless at least for one case: crypto currency miner. In this use case, people are using mostly PCI-Ex 1x riser so they do not plug to the CPU PCI-Ex root port.

                  It supports the distros listed in the README with their stock kernels - IIRC that is Ubuntu 16.04, 16.10 plus Fedora 23.

                  The M265 is an SI chip with no MEC block, so ROCM is not going to work on it.

                    Thanks for the reply. Just to let you know Fedora 23 is reaching EOL on December 20.
