--- Comment #5 from EoD <EoD at xmw.de> --- Created attachment 121742 --> https://bugs.freedesktop.org/attachment.cgi?id=121742&action=edit dmesg after running the uint_add16() kernel (In reply to Hristo Venev from comment #4) > Here are two kernels that fail: > __kernel void uint_div(__global const uint *a, __global const uint *b, > __global uint *c){ > c[0]=a[0]/b[0]; > } > __kernel void uint_add16(__global const uint *a, __global const uint *b, > __global uint *c){ > for(uint i=0;i<16;i++) c[i]=a[i]+b[i]; > } I actually can confirm that the 2nd kernel does cause a GPU stall in the radeon driver (r600/Barts). It causes no problem with amdgpu (radeonsi/Tonga). I am using kernel 4.5.0-rc3, current llvm 3.8 branch and current mesa git. As I am not overly good with OpenCL, is this kernel somehow problematic? -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
