OpenCL runtime and windows suspend/resume

Should OpenCL context on Intel GPU device survive windows suspend/resume ?

I got CL_OUT_OF_HOST_MEMORY error on buffer read presumably after Windows  resume from sleep.

The KMD is supposed to save the state when the system goes to sleep. Can you let me know the steps to reproduce the issue, possibly with a reproducer? Thanks, Raghu

Well, I was not able to reproduce that error specially doing suspend/resume (with password asking on resume or w/o). So it's just coincidence perhaps. OpenCL runtime saves/restores context indeed.
