HSA-Drivers-Linux-AMD on GitHub

Hi,

It looks like a new version of Linux kernel was posted on GitHub today. Is that an official release? I'm asking since it is not merged to the master branch and not yet tagged as a release.

Also, is there a plan to release a version of HSA software package (kernel, run-time library and other compilers) that are meant to be used to together? I have been trying out various HSA related stuff from GirHub and Bitbucket but it is real pain to get the right versions to that works together. For example, I still have not been able to get GCC OMP support working since the SVN server keeps timing out. Kalmar does not work with the latest HSA HLC-HSAIL-Development-LLVM and I still can't use AMD Catalyst OpenCL with HSA enabled kernel.

It looks like the latest kernel release include AMDGPU support but it's only for Carrizo which I can't buy yet. Will AMDGPU work on Kaveri as well?

So many questions... So little answers...

  • The new Linux kernel is an official release, and will be announced by May 31.
  • There will be an associated release of the HSA runtime and associated tools that are compatible with this driver set, which will be officially announced by May 31st, but will be available unofficially before then.
  • There is still no support for an HSA enabled AMD Catalyst OpenCL.
  • The AMDGPU drivers are for Carrizo only, but the old Radeon drivers will still work on Kaveri.
  • I will forward you question regarding the Kalmar compiler to the correct developer.

Thanks for your reply. One more question though. If AMDGPU won't support Kaveri, what is the recommended way of running AMD OpenCL with HSA Kernel on Kaveri? As far as I know, AMD Catalyst driver won't work with HSA enabled kernel.

Do you mean "running HSA with an OpenCL kernel" (via CLOC), or having OpenCL and HSA runtimes available at the same time on the same system ?

The first one is available now (HSA runs over radeon on Kaveri and runs over amdgpu on Carrizo), second is not available yet.


BTW I also need to update the README for the kernel drivers, hope to finish that today.

I meant the second. Is there a plan to support the second scenario? (Since you said yet.) If so, how will it work? Will it work like on Carrizo using amdgpu?

Thanks
