Hi,
In "Host Thread" tab of "GPU: Application Trace" profile run, we get OpenCL call history.
If you are looking for the call stack associated with a particular OpenCL call, do the following:
i. Change CodeXL mode to "Debug" by clicking on "D" icon or by "Debug -> Debug Mode".
ii. Click on "Debug -> Add/Remove Breakpoint" and add the desired OCL call as break point
iii. Click "F5" to start debugging.
iv. Once Break point is hit, "Call Stack" tab shows the desired call stack for the OCL call
Let us know if you need any other help in using CodeXL.
Thanks,
Kalyan P
