config CMD_IOTRACE

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

help
|

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

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