It also maintains a checksum 784 of the trace records (even if space is exhausted) so that the 785 sequence of I/O accesses can be verified. 786 787 When debugging drivers it is useful to see what I/O accesses were 788 done and in what order. 789 790 Even if the individual accesses are of little interest it can be 791 useful to verify that the access pattern is consistent each time 792 an operation is performed. In this case a checksum can be used to 793 characterise the operation of a driver. The checksum can be compared 794 across different runs of the operation to verify that the driver is 795 working properly. 796 797 In particular, when performing major refactoring of the driver, where 798 the access pattern should not change, the checksum provides assurance 799 that the refactoring work has not broken the driver. 800 801 This works by sneaking into the io.h heder for an architecture and 802 redirecting I/O accesses through iotrace's tracing mechanism. 803 804 For now no commands are provided to examine the trace buffer. The 805 format is fairly simple, so 'md' is a reasonable substitute. 806 807 Note: The checksum feature is only useful for I/O regions where the 808 contents do not change outside of software control. Where this is not 809 suitable you can fall back to manually comparing the addresses.
