Sink first-touch work-around code into level zero BE #623

Closed linehill closed 1 year ago

linehill commented 1 year ago

The issue the first-touch code works around is not touched by OpenCL, therefore, sink the code into the level zero backend.

This patch is known to improve performance of HeCBench/extend2-hip 22% on Intel iGPU but not much on PVC.

Judging from the failing tests I probably broke hipEventRecord().
