| bool "Use 4Kb for kernel stacks instead of 8Kb" | |
| depends on DEBUG_KERNEL | |
| 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. | |
