OpenCL Performance: way to extract parallel kernel execution with out-of-order command queue about clr HOT 3 OPEN

I'm using ROCm 6.1 RC, on Linux Ubuntu 22.04 kernel 6.8.1, GPU Radeon Pro VII and Radeon VII.

from clr.

I think I found a clue: in clinfo for all my GPUs (Radeon VII and Radeon Pro VII) I see:

  Queue on Host properties:                              
    Out-of-Order:                                No
    Profiling :                                  Yes
  Queue on Device properties:                            
    Out-of-Order:                                Yes
    Profiling :                                  Yes

So it seems that the Host Command Queue does not implement out-of-order. OK.

Why is that -- is it a limitation of the hardware (particular GPU models), of the ROCm version, not implemented yet in software, something else?

Thanks anyway.
My observation was correct (i.e. the Out-of-order queue is not actually running out-of-order), but the reason was not "a bug" but rather "by design".

One more observation: it's obvious that the HW is capable of running multiple compute kernels in parallel, as it does so when the kernels are queued from multiple processes. So it seems that the non-existent "out-of-order" can't be a limitation of the hardware. It's probably more like "not implemented". Are there plans in that direction?
Is it implemented in HIP?
