RTEMS CPU Architecture Supplement
RTEMS allocates the interrupt stack from the Workspace Area. The amount of memory allocated for the interrupt stack is determined by the interrupt_stack_size field in the CPU Configuration Table. During the initialization process, RTEMS will install its interrupt stack.
The mips port of RTEMS supports a software managed dedicated interrupt stack on those CPU models which do not support a separate interrupt stack in hardware.
