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 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. Acked-by: Tom Lendacky Signed-off-by: Mario Limonciello Signed-off-by: Herbert Xu
