| help |
| If you say Y here the kernel will use a 4Kb stacksize for the |
| kernel stack attached to each process/thread. This facilitates |
| running more threads on a system and also reduces the pressure |
| on the VM subsystem for higher order allocations. This option |
| will also use IRQ stacks to compensate for the reduced stackspace. |

| config METAG_FUNCTION_TRACE |
| bool "Output Meta real-time trace data for function entry/exit" |
| help |
| If you say Y here the kernel will use the Meta hardware trace |
| unit to output information about function entry and exit that |
| can be used by a debugger for profiling and call-graphs. |

| config METAG_POISON_CATCH_BUFFERS |
| bool "Poison catch buffer contents on kernel entry" |
| help |
| If you say Y here the kernel will write poison data to the |
| catch buffer registers on kernel entry. This will make any |
| problem with catch buffer handling much more apparent. |
