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.

# We should really only have to provide one of the following two values,
# but a bug in the Zephyr SDK for x86 precludes the use of division in
# the assembler. For now, we require that these values be specified manually,
# and we check to be sure they're a valid combination in arch.h. yes, ugh.
config ISR_DEPTH
int "Maximum IRQ nesting depth"
default 4
help
The more nesting allowed, the more room is required for IRQ stacks.
config ISR_SUBSTACK_SIZE
int "Size of ISR substacks"
default 4096
help
Number of bytes from the ISR stack to reserve for each nested IRQ
level. Must be a multiple of 16 to main stack alignment. Note that
CONFIG_ISR_SUBSTACK_SIZE * CONFIG_ISR_DEPTH must be equal to
CONFIG_ISR_STACK_SIZE.
