It also maintains a checksum 678 of the trace records (even if space is exhausted) so that the 679 sequence of I/O accesses can be verified. 680 681 When debugging drivers it is useful to see what I/O accesses were 682 done and in what order. 683 684 Even if the individual accesses are of little interest it can be 685 useful to verify that the access pattern is consistent each time 686 an operation is performed. In this case a checksum can be used to 687 characterise the operation of a driver. The checksum can be compared 688 across different runs of the operation to verify that the driver is 689 working properly. 690 691 In particular, when performing major refactoring of the driver, where 692 the access pattern should not change, the checksum provides assurance 693 that the refactoring work has not broken the driver. 694 695 This works by sneaking into the io.h heder for an architecture and 696 redirecting I/O accesses through iotrace's tracing mechanism. 697 698 For now no commands are provided to examine the trace buffer. The 699 format is fairly simple, so 'md' is a reasonable substitute. 700 701 Note: The checksum feature is only useful for I/O regions where the 702 contents do not change outside of software control. Where this is not 703 suitable you can fall back to manually comparing the addresses.
