701 bool "io - Support for performing I/O accesses"
702 help
703 Provides an 'iod' command to display I/O space and an 'iow' command

705 checking the state of devices during boot when debugging device
706 drivers, etc.

708config CMD_IOTRACE
709 bool "iotrace - Support for tracing I/O activity"
710 help
711 Provides an 'iotrace' command which supports recording I/O reads and
712 writes in a trace buffer in memory . It also maintains a checksum
713 of the trace records (even if space is exhausted) so that the
714 sequence of I/O accesses can be verified.
715
716 When debugging drivers it is useful to see what I/O accesses were
717 done and in what order.
718
719 Even if the individual accesses are of little interest it can be
720 useful to verify that the access pattern is consistent each time
721 an operation is performed. In this case a checksum can be used to
722 characterise the operation of a driver. The checksum can be compared
723 across different runs of the operation to verify that the driver is
724 working properly.
725
726 In particular, when performing major refactoring of the driver, where
727 the access pattern should not change, the checksum provides assurance
728 that the refactoring work has not broken the driver.
729
730 This works by sneaking into the io.h heder for an architecture and
731 redirecting I/O accesses through iotrace's tracing mechanism.
732
733 For now no commands are provided to examine the trace buffer. The
734 format is fairly simple, so 'md' is a reasonable substitute.
735
736 Note: The checksum feature is only useful for I/O regions where the
737 contents do not change outside of software control. Where this is not
738 suitable you can fall back to manually comparing the addresses. It
739 might be useful to enhance tracing to only checksum the accesses and
740 not the data read/written.
