CONFIG_PRIVILEGED_STACK_SIZE¶
Size of privileged stack
Type: int
Help¶
This option sets the privileged stack region size that will be used
in addition to the user mode thread stack. During normal execution,
this region will be inaccessible from user mode. During system calls,
this region will be utilized by the system call. This value must be
a multiple of the minimum stack alignment.
Direct dependencies¶
(COVERAGE && BOARD_MPS2_AN385) || ARM64 || ARCH_HAS_USERSPACE
(Includes any dependencies from ifs and menus.)
