CONFIG_ARC_EXCEPTION_STACK_SIZE

ARC exception handling stack size

Type: int

Help

Size in bytes of exception handling stack which is at the top of
interrupt stack to get smaller memory footprint because exception
is not frequent. To reduce the impact on interrupt handling,
especially nested interrupt, it cannot be too large.

Direct dependencies

(Includes any dependencies from ifs and menus.)

Defaults

• 768 if !64BIT

• 2048 if 64BIT
