It also maintains a checksum 778 of the trace records (even if space is exhausted) so that the 779 sequence of I/O accesses can be verified. 780 781 When debugging drivers it is useful to see what I/O accesses were 782 done and in what order. 783 784 Even if the individual accesses are of little interest it can be 785 useful to verify that the access pattern is consistent each time 786 an operation is performed. In this case a checksum can be used to 787 characterise the operation of a driver. The checksum can be compared 788 across different runs of the operation to verify that the driver is 789 working properly. 790 791 In particular, when performing major refactoring of the driver, where 792 the access pattern should not change, the checksum provides assurance 793 that the refactoring work has not broken the driver. 794 795 This works by sneaking into the io.h heder for an architecture and 796 redirecting I/O accesses through iotrace's tracing mechanism. 797 798 For now no commands are provided to examine the trace buffer. The 799 format is fairly simple, so 'md' is a reasonable substitute. 800 801 Note: The checksum feature is only useful for I/O regions where the 802 contents do not change outside of software control. Where this is not 803 suitable you can fall back to manually comparing the addresses.
