It also maintains a checksum 686 of the trace records (even if space is exhausted) so that the 687 sequence of I/O accesses can be verified. 688 689 When debugging drivers it is useful to see what I/O accesses were 690 done and in what order. 691 692 Even if the individual accesses are of little interest it can be 693 useful to verify that the access pattern is consistent each time 694 an operation is performed. In this case a checksum can be used to 695 characterise the operation of a driver. The checksum can be compared 696 across different runs of the operation to verify that the driver is 697 working properly. 698 699 In particular, when performing major refactoring of the driver, where 700 the access pattern should not change, the checksum provides assurance 701 that the refactoring work has not broken the driver. 702 703 This works by sneaking into the io.h heder for an architecture and 704 redirecting I/O accesses through iotrace's tracing mechanism. 705 706 For now no commands are provided to examine the trace buffer. The 707 format is fairly simple, so 'md' is a reasonable substitute. 708 709 Note: The checksum feature is only useful for I/O regions where the 710 contents do not change outside of software control. Where this is not 711 suitable you can fall back to manually comparing the addresses.
