hi,
I have two AMD GPU when I do clinfo i get below information. I am using OpenCL 1.2 and WX9100

below is the trace. I have dirvers installed as amdgpu-pro-18.10-572953.tar.xz.
Same piece of code was woring on with older drivers.
1 - Any idea why my clinfo showing zeros
| Why zero's |
|---|
Max pipe arguments: 0 Max pipe active reservations: 0 Max pipe packet size: 0 Max global variable size: 0 Max global variable preferred total size: 0 Max read/write image args: 0 Max on device events: 0 Queue on device max size: 0 Max on device queues: 0 Queue on device preferred size: 0 |
2 - Any reason why infinite hung in "aclCompile()".
