Summary0004722: 'amdgpu 0000:04:00.0: kfd not supported on this ASIC' OpenCL AMD driver 17.50 -552542 Radeon PRO DUO (Polaris)
DescriptionProblem description
When installed AMD Radeon PRO DUO 100-506048 (Polaris) dual GPU video card and latest AMD OpenCL 17.50-552542 driver loaded there is no OpenCL support, and I have kernel message:

'amdgpu 0000:04:00.0: kfd not supported on this ASIC'.

AMD 17.50 OpenCL only driver I use 'amdgpu-compute-17.50-552542.tar' has been attached.

Searching says that Kali 2018.1 kernel v14.4 have not implemented latest patches to support kfd feature for AMD dual GPU video cards with Fuji and/or Polaris architecture. So seems kernel update/patching needed.

Hope the latest Kali release will have stable 4.16.5 or 4.17 kernel with all the patches implemented from ROCm OpenCL stack and Felix Kuehling Felix.Kuehling at amd.com to have dual GPU cards working for OpenCL.

drm/amdgpu: Fix KFD initialization for multi-GPU systems

kfd2kgd is device-specific, so it should not be a global variable.
Merge amdgpu_amdkfd_load_interface and amdgpu_amdkfd_device_probe
so that it's only needed as a local variable in one function.

1.9.1

As people reports AMD Radeon dual GPU cards works with ROCm OpenCL stack with patches for 4.13 kernel as has been written in the post listed below:
-----------------------------------
https://bbs.archlinux.org/viewtopic.php?pid=1761069#p1761069

Vega GPUs are meant to be supported by AMD's new open-sourced ROCm OpenCL stack, but using that requires kernel patches that haven't been mainlined yet... AMD provides a custom kernel with those patches, but based on 4.13, meaning it won't have the DC patches from 4.15, so you'll only be able to run it headless or with the full proprietary amdgpu-pro stack. Using that kernel and the rocm libraries from the 17.50 amdgpu-pro driver (namely libamdocl64.so, libhsakmt.so and libhsa-runtime64.so in /opt/amdgpu-pro/lib/x86_64-linux-gnu), I was able to get OpenCL working on my vega 64.
-----------------------------------

Thank you for your attention to the problem.

Paron
Steps To ReproduceInstall in your system AMD Radeon PRO DUO 100-506048 (Polaris) dual GPU video card and install amd gpu 17.50-552542 driver.

Next reboot you can see 'amdgpu 0000:04:00.0: kfd not supported on this ASIC' error message.
Additional InformationCan help testing any changes from Kali current to have this feature fully working in next releases.

Which kernel version planned for the upcoming release? Does it have kfd support implemented?
