crypto: ccp - Update return values for some unit tests

2024-02-24T00:41:20+00:00

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

crypto: tcrypt - add script tcrypt_speed_compare.py

2023-12-29T03:25:55+00:00

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. For operations in seconds

crypto: ccp - Fix some unfused tests

2023-09-15T10:29:45+00:00

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 passing

2023-09-15T10:29:45+00:00

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 handling

2023-09-15T10:29:45+00:00

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 control

2023-07-20T10:15:12+00:00

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 Control

2023-07-20T10:14:57+00:00

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.

intended to be loaded and used by higher level languages
