CONFIG_CC3XX_MUTEX_LOCK

Use mutex variables for mutually exclusive access to CC3XX resources

Type: bool

Help

Enables exclusive access to the ARM CryptoCell hardware using an RTOS mutex that has priority inheritance. The mutex lock is safe across threads and/or interrupts with different priority. Using an RTOS mutex comes at a cost of lower performance.
