965 help
966 Provides an 'iotrace' command which supports recording I/O reads and
967 writes in a trace buffer in memory . It also maintains a checksum
968 of the trace records (even if space is exhausted) so that the
969 sequence of I/O accesses can be verified.
970
971 When debugging drivers it is useful to see what I/O accesses were
972 done and in what order.
973
974 Even if the individual accesses are of little interest it can be
975 useful to verify that the access pattern is consistent each time
976 an operation is performed. In this case a checksum can be used to
977 characterise the operation of a driver. The checksum can be compared
978 across different runs of the operation to verify that the driver is
979 working properly.
980
981 In particular, when performing major refactoring of the driver, where
982 the access pattern should not change, the checksum provides assurance
983 that the refactoring work has not broken the driver.
984
985 This works by sneaking into the io.h heder for an architecture and
986 redirecting I/O accesses through iotrace's tracing mechanism.
987
988 For now no commands are provided to examine the trace buffer. The
989 format is fairly simple, so 'md' is a reasonable substitute.
990
991 Note: The checksum feature is only useful for I/O regions where the
992 contents do not change outside of software control. Where this is not
993 suitable you can fall back to manually comparing the addresses. It
994 might be useful to enhance tracing to only checksum the accesses and
995 not the data read/written.
