It also maintains a checksum 785 of the trace records (even if space is exhausted) so that the 786 sequence of I/O accesses can be verified. 787 788 When debugging drivers it is useful to see what I/O accesses were 789 done and in what order. 790 791 Even if the individual accesses are of little interest it can be 792 useful to verify that the access pattern is consistent each time 793 an operation is performed. In this case a checksum can be used to 794 characterise the operation of a driver. The checksum can be compared 795 across different runs of the operation to verify that the driver is 796 working properly. 797 798 In particular, when performing major refactoring of the driver, where 799 the access pattern should not change, the checksum provides assurance 800 that the refactoring work has not broken the driver. 801 802 This works by sneaking into the io.h heder for an architecture and 803 redirecting I/O accesses through iotrace's tracing mechanism. 804 805 For now no commands are provided to examine the trace buffer. The 806 format is fairly simple, so 'md' is a reasonable substitute. 807 808 Note: The checksum feature is only useful for I/O regions where the 809 contents do not change outside of software control. Where this is not 810 suitable you can fall back to manually comparing the addresses.
