GTPin: Funtime Sample Tool

The Funtime tool counts the cycles it takes for each kernel to execute from the beginning to the end

## Running Funtime tool

To run the Funtime tool in its default configuration, use this command:

    Profilers/Bin/gtpin -t funtime -- app

## How to understand Funtime results

When you run the in-house GTPin Funtime tool in its default configuration, the directory `GTPIN_PROFILE_FUNTIME0` is generated. GTPin saves the profiling results in the file `GTPIN_PROFILE_FUNTIME0\Session_Final\funtime.txt`. The results are presented in the following format:

    ### Kernel/Shader execution-time profile generated by GTPin ###

Each line represents a single run (dispatch to HW device) of specific kernel, where the fields have the following meaning:

- Name - The name of the kernel.
- HashID - The hash ID of the IR representation of this kernel.
- SIMD - The SIMD width to which the kernel was compiled (8, 16, or 32).
- Type - The kernel type (PS - Pixel Shader, VS - Vertex Shader, DS - Domain Shader, GS - Geometry Shader, HS - Hull Shader, or CS - Compute Shader).
- Freq. - The number of times an instance of the kernel was dispatched to any of the HW threads during the current run.
- Total-Cycle - The total number of cycles (accumulated over all HW threads) it took for the kernel to run from its beginning to end.
- Avg-Cycles - The average number of cycles it takes for the kernel instance to run on a single HW thread. This number is equal to `Total-Cycle/Freq`.
- Skipped - Internal GTPin information.
- Platform - The platform supported by the application: Intel® oneAPI Level Zero* (Level Zero*), OpenCL*, Microsoft DX11*, Microsoft DX12*, and/or Vulkan*.
- Execution descriptor - Per platform metadata.
  - Level Zero - Device Enqueue.
  - OpenCL - Device Enqueue.
  - DX11 - Device Draw.
  - DX12 - Device CommandList Draw PSO.
  - Vulkan - Device CommandList Draw PSO.
    where:
    - Device - The ID of the logical device on which the kernel was run.
    - Enqueue - The ID of the Enqueue command.
    - Draw - The ID of the Draw command.
    - CommandList - The ID of the Command List.
    - PSO - The ID of the PSO (Pipeline State Object).

If the name of the kernel is not known to GTPin, GTPin creates an artificial name in the format: CS_asmf54af91315561f54_simd8 where the prefix indicates the kernel type; the suffix indicates the SIMD width to which this kernel was compiled; and the 16-digit number is the hash ID of the IR representation of this kernel.
