Description

Hi,
the clinfo always reports error "ERROR: clCreateKernel(-5)" while checking "Kernel Preferred work group size multiple". For AMD's own driver, there is no problem.
The problem has been there for a few years.
Thanks!

Research direction

Reproduce the report by running clinfo on the OpenCLOn12 platform with the listed AMD devices and focus on the "Kernel Preferred work group size multiple" query. Trace the clCreateKernel(-5) path in the OpenCLOn12 implementation, then verify that clinfo reports this property without an error for the affected device.
