CONFIG_X86_EXCEPTION_STACK_SIZE

Size of the exception stack(s)

Type: int

Help

The exception stack(s) (one per CPU) are used both for exception
processing and early kernel/CPU initialization. They need only
support limited call-tree depth and must fit into the low core,
so they are typically smaller than the ISR stacks.

Direct dependencies

X86_64 && X86

(Includes any dependencies from ifs and menus.)

Default

  • 4096
