CONFIG_ARCH_POSIX_RECOMMENDED_STACK_SIZE

(No prompt – not directly user assignable.)

Type: int

Help

In bytes, stack size for Zephyr threads meant only for the POSIX
architecture.
(In this architecture only part of the thread status is kept in the Zephyr
thread stack, the real stack is the native underlying pthread stack.
Therefore the allocated stack can be limited to this size)

Direct dependencies

ARCH_POSIX

(Includes any dependencies from ifs and menus.)

Defaults

• 40 if 64BIT

• 24
