    longDescription = ''
      View GPU utilization, both for the total activity percent and individual
      blocks. Supports R600 and later cards: even Southern Islands should work.
      Works with both the open drivers and AMD Catalyst. Total GPU utilization
      is also valid for OpenCL loads; the other blocks are only useful for GL
      loads. Requires root rights or other permissions to read /dev/mem.
