    description "
          In most circumstances the kernel should provide the
          instrumentation circular buffer itself. Occasionally
          application code may wish to provide the buffer instead,
          giving the application code more convenient access to the
          buffer. This also makes it possible to put the circular
          buffer in special areas of memory, for example a region that
          is shared with the host."

    description   "
        If kernel instrumentation is enabled then the instrumentation
        data goes into a circular buffer. A larger buffer allows
        more data to be stored, but at a significant cost in memory.
        The value of this option corresponds to the number of entries
        in the table, and typically each entry will require 16 bytes
        of memory."

        The kernel can either collect all instrumentation events, or
        it can filter out events at runtime based on a set of flags.
        For example it would be possible to decide at runtime that
        only scheduler and interrupt instrumentation flags are of
        interest and that all other flags should be ignored. This
        flag mechanism involves extra code and processor cycle
        overhead in the instrumentation code, so it can be disabled
        if the application developer is interested in all
        instrumentation events."
