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
