It also maintains a checksum 792 of the trace records (even if space is exhausted) so that the 793 sequence of I/O accesses can be verified. 794 795 When debugging drivers it is useful to see what I/O accesses were 796 done and in what order. 797 798 Even if the individual accesses are of little interest it can be 799 useful to verify that the access pattern is consistent each time 800 an operation is performed. In this case a checksum can be used to 801 characterise the operation of a driver. The checksum can be compared 802 across different runs of the operation to verify that the driver is 803 working properly. 804 805 In particular, when performing major refactoring of the driver, where 806 the access pattern should not change, the checksum provides assurance 807 that the refactoring work has not broken the driver. 808 809 This works by sneaking into the io.h heder for an architecture and 810 redirecting I/O accesses through iotrace's tracing mechanism. 811 812 For now no commands are provided to examine the trace buffer. The 813 format is fairly simple, so 'md' is a reasonable substitute. 814 815 Note: The checksum feature is only useful for I/O regions where the 816 contents do not change outside of software control. Where this is not 817 suitable you can fall back to manually comparing the addresses.
