It also maintains a checksum 775 of the trace records (even if space is exhausted) so that the 776 sequence of I/O accesses can be verified. 777 778 When debugging drivers it is useful to see what I/O accesses were 779 done and in what order. 780 781 Even if the individual accesses are of little interest it can be 782 useful to verify that the access pattern is consistent each time 783 an operation is performed. In this case a checksum can be used to 784 characterise the operation of a driver. The checksum can be compared 785 across different runs of the operation to verify that the driver is 786 working properly. 787 788 In particular, when performing major refactoring of the driver, where 789 the access pattern should not change, the checksum provides assurance 790 that the refactoring work has not broken the driver. 791 792 This works by sneaking into the io.h heder for an architecture and 793 redirecting I/O accesses through iotrace's tracing mechanism. 794 795 For now no commands are provided to examine the trace buffer. The 796 format is fairly simple, so 'md' is a reasonable substitute. 797 798 Note: The checksum feature is only useful for I/O regions where the 799 contents do not change outside of software control. Where this is not 800 suitable you can fall back to manually comparing the addresses.
