lbclc/llvm: OpenCL on modern AMD GPUs

#1 Post by wanne »

This is a duplicate of this: https://debianforum.de/forum/viewtopic.php?t=186074
I want to use OpenCL on the Radeon RX 7900 XT.

But I get errors like this:

Code: Select all

=== CL_PROGRAM_BUILD_LOG ===
fatal error: cannot open file '/usr/lib/clc/gfx1100-amdgcn-mesa-mesa3d.bc': No such file or directory
  Preferred work group size multiple (kernel)     <getWGsizes:1504: create kernel : error -46>

Code: Select all

clCompileProgram(): CL_COMPILE_PROGRAM_FAILURE

fatal error: cannot open file '/usr/lib/clc/gfx1100-amdgcn-mesa-mesa3d.bc': No such file or directory
Problem seems that my libclc is to old. But even if I download the 16 Alpha from llvm, it seems that I get only support for Cards that are older than 5 years (gfx1010 and older).
So is there really no useful support for GPU Computing on AMD-Cards at all? I mean before using 5 year old cards I rather use a modern day CPU.

Most people recommend to use the AMD-PRO-driver. But it is out of support for a while and not downloadable any more.
