          DRM supports several counters which were used for rough performance

          characterization. This stat counter system is deprecated and should not

          be used. If performance monitoring is desired, the developer should

          investigate and potentially enhance the kernel perf and tracing

          infrastructure to export GPU related performance information for

          consumption by performance monitoring tools and applications.
