It also maintains a checksum 768 of the trace records (even if space is exhausted) so that the 769 sequence of I/O accesses can be verified. 770 771 When debugging drivers it is useful to see what I/O accesses were 772 done and in what order. 773 774 Even if the individual accesses are of little interest it can be 775 useful to verify that the access pattern is consistent each time 776 an operation is performed. In this case a checksum can be used to 777 characterise the operation of a driver. The checksum can be compared 778 across different runs of the operation to verify that the driver is 779 working properly. 780 781 In particular, when performing major refactoring of the driver, where 782 the access pattern should not change, the checksum provides assurance 783 that the refactoring work has not broken the driver. 784 785 This works by sneaking into the io.h heder for an architecture and 786 redirecting I/O accesses through iotrace's tracing mechanism. 787 788 For now no commands are provided to examine the trace buffer. The 789 format is fairly simple, so 'md' is a reasonable substitute. 790 791 Note: The checksum feature is only useful for I/O regions where the 792 contents do not change outside of software control. Where this is not 793 suitable you can fall back to manually comparing the addresses.
