How to add burst job timing to the profiler.

ProfilerMarker.cs

public unsafe class JobTestSystem : JobComponentSystem
{
    private ProfilerMarker _marker;

    protected override void OnCreateManager()
    {
        _marker = new ProfilerMarker("Job1z");
    }

    protected override JobHandle OnUpdate(JobHandle inputDeps)
    {
        new Job
        {
           Marker = _marker,

        }.Run();

        Debug.Log($"Marker {_marker} Ptr={(long)UnsafeUtility.AddressOf(ref _marker):X}");

        return inputDeps;
    }

    [BurstCompile]
    public struct Job : IJob
    {
        public int TypeIndex;

        public void Execute()
        {
            Marker.Begin();
      
            unchecked
            {
                for (int i = 0; i < 1000000; i++)
                {
                    TypeIndex += i * (int)Math.Sqrt(i+1);
                }
            }
            Marker.End();
        }

        public ProfilerMarker Marker;
    }
}
