  				  (RB, Rasterizer/Primitive, Geometry)
  -rbplus			RB+ (for override)
  				  (RB == 4-ROP, RB+ == 8-ROP) 
  -h, --help			display this help and exit

OPTIONS:
  --col=NUM			setting number of diagram column (default: 2)
  --arch=gfx(9|10|10.3)		override GFX IP/Architecture
  --se=NUM			override number of ShaderEngine
  --sa-per-se=NUM, --sps=NUM	override number of ShaderArray per ShaderEngine

  --min-cu-per-sa=NUM, --mcps=NUM
  				override number of min CU per ShaderArray
  --rb=NUM			override number of RenderBackend
  --l2c-block=NUM, --l2cb=NUM	override number of L2cache block
  --l2c-size=NUM, --l2cs=NUM	override L2cache size (KiB)
  
  -image			output image of diagram
  				  output to: /tmp/<GPU_NAME>-diagram.png
  				  requirement: imagemagick, "Dejavu Sans Mono" font
