| 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. | |
