  894. writes in a trace buffer in memory . It also maintains a checksum
  895. of the trace records (even if space is exhausted) so that the
  896. sequence of I/O accesses can be verified.
  897. When debugging drivers it is useful to see what I/O accesses were
  898. done and in what order.
  899. Even if the individual accesses are of little interest it can be
  900. useful to verify that the access pattern is consistent each time
  901. an operation is performed. In this case a checksum can be used to
  902. characterise the operation of a driver. The checksum can be compared
  903. across different runs of the operation to verify that the driver is
  904. working properly.
  905. In particular, when performing major refactoring of the driver, where
  906. the access pattern should not change, the checksum provides assurance
  907. that the refactoring work has not broken the driver.
  908. This works by sneaking into the io.h heder for an architecture and
  909. redirecting I/O accesses through iotrace's tracing mechanism.
  910. For now no commands are provided to examine the trace buffer. The
  911. format is fairly simple, so 'md' is a reasonable substitute.
  912. Note: The checksum feature is only useful for I/O regions where the
  913. contents do not change outside of software control. Where this is not
  914. suitable you can fall back to manually comparing the addresses. It
  915. might be useful to enhance tracing to only checksum the accesses and
  916. not the data read/written.
