CONFIG_ENTROPY_STM32_THR_THRESHOLD

Thread-mode random number pool low-water threshold

Type: int

Help

Low water-mark threshold in bytes to trigger entropy generation for
thread mode consumers. As soon as the number of available bytes in the
buffer goes below this number hardware entropy generation will be
started.

Direct dependencies

ENTROPY_STM32_RNG && ENTROPY_GENERATOR

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to the empty string.
