10    bool "Use 4Kb for kernel stacks instead of 8Kb"
11    depends on DEBUG_KERNEL
12    help
13      If you say Y here the kernel will use a 4Kb stacksize for the
14      kernel stack attached to each process/thread. This facilitates
15      running more threads on a system and also reduces the pressure
16      on the VM subsystem for higher order allocations. This option
17      will also use IRQ stacks to compensate for the reduced stackspace.

19config METAG_FUNCTION_TRACE
20    bool "Output Meta real-time trace data for function entry/exit"
21    help
22      If you say Y here the kernel will use the Meta hardware trace
23      unit to output information about function entry and exit that
24      can be used by a debugger for profiling and call-graphs.
25
26config METAG_POISON_CATCH_BUFFERS
27    bool "Poison catch buffer contents on kernel entry"
28    help
29      If you say Y here the kernel will write poison data to the
30      catch buffer registers on kernel entry. This will make any
31      problem with catch buffer handling much more apparent.
