It also maintains a checksum 642 of the trace records (even if space is exhausted) so that the 643 sequence of I/O accesses can be verified. 644 645 When debugging drivers it is useful to see what I/O accesses were 646 done and in what order. 647 648 Even if the individual accesses are of little interest it can be 649 useful to verify that the access pattern is consistent each time 650 an operation is performed. In this case a checksum can be used to 651 characterise the operation of a driver. The checksum can be compared 652 across different runs of the operation to verify that the driver is 653 working properly. 654 655 In particular, when performing major refactoring of the driver, where 656 the access pattern should not change, the checksum provides assurance 657 that the refactoring work has not broken the driver. 658 659 This works by sneaking into the io.h heder for an architecture and 660 redirecting I/O accesses through iotrace's tracing mechanism. 661 662 For now no commands are provided to examine the trace buffer. The 663 format is fairly simple, so 'md' is a reasonable substitute. 664 665 Note: The checksum feature is only useful for I/O regions where the 666 contents do not change outside of software control. Where this is not 667 suitable you can fall back to manually comparing the addresses.
