 |
|
I have a Ryzen 5 3400G APU which has a Vega 11 (gfx9) IGPU. I've installed | Code: | | dev-libs/opencl-runtime |
. However the output of clinfo is this:
| Code: | Number of platforms 1
Platform Name AMD Accelerated Parallel Processing
Platform Vendor Advanced Micro Devices, Inc.
Platform Version OpenCL 2.0 AMD-APP.dbg (3275.0)
Platform Profile FULL_PROFILE
Platform Extensions cl_khr_icd cl_amd_event_callback
Platform Extensions function suffix AMD
Platform Name AMD Accelerated Parallel Processing
Number of devices 0
NULL platform behavior
clGetPlatformInfo(NULL, CL_PLATFORM_NAME, ...) No platform
clGetDeviceIDs(NULL, CL_DEVICE_TYPE_ALL, ...) No platform
clCreateContext(NULL, ...) [default] No platform
clCreateContext(NULL, ...) [other]
clCreateContextFromType(NULL, CL_DEVICE_TYPE_DEFAULT) No devices found in platform
clCreateContextFromType(NULL, CL_DEVICE_TYPE_CPU) No devices found in platform
clCreateContextFromType(NULL, CL_DEVICE_TYPE_GPU) No devices found in platform
clCreateContextFromType(NULL, CL_DEVICE_TYPE_ACCELERATOR) No devices found in platform
clCreateContextFromType(NULL, CL_DEVICE_TYPE_CUSTOM) No devices found in platform
clCreateContextFromType(NULL, CL_DEVICE_TYPE_ALL) No devices found in platform |
Here is the output of :

I've searched the forums but it's inconclusive and outdated (e.g. one thread talks heavily of `eselect-opencl`, which doesn't exist anymore). The most promising is https://forums.gentoo.org/viewtopic-t-1121939-highlight-opencl.html that thread. However, that discourages the use of ROCm. It should be noted that prior to installing ROCm I installed amdgpu-pro-opencl and clinfo had the same output, but I used the following PKGBUILD in arch linux and I managed to get OpenCL working so it's not a hardware issue: https://aur.archlinux.org/cgit/aur.git/plain/PKGBUILD?h=opencl-amd&id=88cc39d2619dddf7c62fc4e4eb3726ab04cb8f92.
I guess my last hope would be to follow that PKGBUILD by hand?
