- config 4KSTACKS
- 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.
