1285 bool "iotrace - Support for tracing I/O activity"

1287 Provides an 'iotrace' command which supports recording I/O reads and

1289 of the trace records (even if space is exhausted) so that the
1290 sequence of I/O accesses can be verified.
1292 When debugging drivers it is useful to see what I/O accesses were
1293 done and in what order.
1295 Even if the individual accesses are of little interest it can be
1296 useful to verify that the access pattern is consistent each time
1297 an operation is performed. In this case a checksum can be used to
1298 characterise the operation of a driver. The checksum can be compared
1299 across different runs of the operation to verify that the driver is
1300 working properly.
1302 In particular, when performing major refactoring of the driver, where
1303 the access pattern should not change, the checksum provides assurance
1304 that the refactoring work has not broken the driver.
1306 This works by sneaking into the io.h heder for an architecture and
1307 redirecting I/O accesses through iotrace's tracing mechanism.
1309 For now no commands are provided to examine the trace buffer. The
1310 format is fairly simple, so 'md' is a reasonable substitute.
1312 Note: The checksum feature is only useful for I/O regions where the
1313 contents do not change outside of software control. Where this is not
1314 suitable you can fall back to manually comparing the addresses. It
1315 might be useful to enhance tracing to only checksum the accesses and
1316 not the data read/written.
