| |
| 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. |

| Encapsulating data as a blob |
| Each time that the Blob Protocol is used to protect data, a |

| This random key is itself encrypted using a key which is derived |
| from SoC's non-volatile secret key and a 16 bit Key identifier. |
| The resulting encrypted key along with encrypted data is called a |
| blob. The non-volatile secure key is available for use only during |
| secure boot. |

| During decapsulation, the reverse process is performed to get back |
| the original data. |
