800
801config CMD_IOTRACE
802	bool "iotrace - Support for tracing I/O activity"
803	help
804	  Provides an 'iotrace' command which supports recording I/O reads and
805	  writes in a trace buffer in memory . It also maintains a checksum
806	  of the trace records (even if space is exhausted) so that the
807	  sequence of I/O accesses can be verified.
808
809	  When debugging drivers it is useful to see what I/O accesses were
810	  done and in what order.
811
812	  Even if the individual accesses are of little interest it can be
813	  useful to verify that the access pattern is consistent each time
814	  an operation is performed. In this case a checksum can be used to
815	  characterise the operation of a driver. The checksum can be compared
816	  across different runs of the operation to verify that the driver is
817	  working properly.
818
819	  In particular, when performing major refactoring of the driver, where
820	  the access pattern should not change, the checksum provides assurance
821	  that the refactoring work has not broken the driver.
822
823	  This works by sneaking into the io.h heder for an architecture and
824	  redirecting I/O accesses through iotrace's tracing mechanism.
825
826	  For now no commands are provided to examine the trace buffer. The
827	  format is fairly simple, so 'md' is a reasonable substitute.
828
829	  Note: The checksum feature is only useful for I/O regions where the
830	  contents do not change outside of software control. Where this is not
831	  suitable you can fall back to manually comparing the addresses. It
832	  might be useful to enhance tracing to only checksum the accesses and
833	  not the data read/written.
