* crypto: ccp - Update return values for some unit testsMario Limonciello2024-02-241-3/+5
| | | | | | | | | | | | | | | Until authenticated the platform enforces a state machine. Adjust unit tests with this in mind. Correct the return codes for all the states the unit tests ends up hitting: * Set Param / Get Param: DBC_ERROR_BAD_STATE * Set UID: DBC_ERROR_SIGNATURE_INVALID * Authencitated Nonce: DBC_ERROR_BAD_PARAMETERS Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: tcrypt - add script tcrypt_speed_compare.pyWangJinchao2023-12-291-0/+190
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create a script for comparing tcrypt speed test logs. The script will systematically analyze differences item by item and provide a summary (average). This tool is useful for evaluating the stability of cryptographic module algorithms and assisting with performance optimization. Please note that for such a comparison, stability depends on whether we allow frequency to float or pin the frequency. The script produces comparisons in two scenes: 1.

* crypto: ccp - Fix some unfused testsMario Limonciello2023-09-151-13/+13
| | | | | | | | | | | Some of the tests for unfused parts referenced a named member parameter, but when the test suite was switched to call a python ctypes library they weren't updated. Adjust them to refer to the first argument of the process_param() call and set the data type of the signature appropriately.

* crypto: ccp - Fix sample application signature passingMario Limonciello2023-09-152-2/+4
| | | | | | | | | | | | | When parameters are sent the PSP returns back it's own signature for the application to verify the authenticity of the result. Display this signature to the caller instead of the one the caller sent.

* crypto: ccp - Fix DBC sample application error handlingMario Limonciello2023-09-152-10/+9
| | | | | | | | | | | | | The sample application was taking values from ioctl() and treating those as the error codes to present to a user. This is incorrect when ret is non-zero, the error is stored to `errno`. Use this value instead.

* crypto: ccp - Add unit tests for dynamic boost controlMario Limonciello2023-07-201-0/+266
| | | | | | | | | | | | | | | | | | | | Interacting with dynamic boost control messages requires the caller to supply a signature. To allow validation of individual dynamic boost control components, introduce a set of tests that can be run. The tests can be run in 3 distinct different environments, and so certain tests will be skipped depending on the environment. 1. Systems that do not support DBC. 2. Production systems that support DBC but are secured silicon. 3. Pre-production systems that support DBC but are unsecured silicon. Unsecured silicon does not validate the signature, and so this allows testing more of the state machine and functionality.

* crypto: ccp - Add a sample python script for Dynamic Boost ControlMario Limonciello2023-07-203-0/+199
| | | | | | | | | | | | | | | | Dynamic Boost Control commands are triggered by userspace with an IOCTL interface that userspace will prepare proper buffers for a request. To allow prototyping and testing this interface, add a python3 command line script that loads the dbc_library.so for utilizing the IOCTLs. The signature to use and UID are passed as arguments to this script.
