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.
