Future versions of this specification may add extra substructures at the end of this structure.

Member Function Documentation

MBEDTLS_PRIVATE() [1/3]

uint32_t psa_drv_se_t::MBEDTLS_PRIVATE ( hal_version )

The version of the driver HAL that this driver implements.

This is a protection against loading driver binaries built against a different version of this specification. Use PSA_DRV_SE_HAL_VERSION .

MBEDTLS_PRIVATE() [2/3]

size_t psa_drv_se_t::MBEDTLS_PRIVATE ( persistent_data_size )

The size of the driver's persistent data in bytes.

This can be 0 if the driver does not need persistent data.

See the documentation of psa_drv_se_context_t::persistent_data for more information about why and how a driver can use persistent data.

MBEDTLS_PRIVATE() [3/3]

psa_drv_se_init_t psa_drv_se_t::MBEDTLS_PRIVATE ( p_init )

The driver initialization function.

This function is called once during the initialization of the PSA Cryptography subsystem, before any other function of the driver is called. If this function returns a failure status, the driver will be unusable, at least until the next system reset.

If this field is NULL , it is equivalent to a function that does nothing and returns PSA_SUCCESS .
