  12        help
  13          This option will cause messages to be printed if free stack space
  14          drops below a certain limit.

  16config 4KSTACKS
  17        bool "Use 4Kb for kernel stacks instead of 8Kb"
  18        depends on DEBUG_KERNEL
  19        help
  20          If you say Y here the kernel will use a 4Kb stacksize for the
  21          kernel stack attached to each process/thread. This facilitates
  22          running more threads on a system and also reduces the pressure
  23          on the VM subsystem for higher order allocations. This option
  24          will also use IRQ stacks to compensate for the reduced stackspace.

  26config METAG_FUNCTION_TRACE
  27        bool "Output Meta real-time trace data for function entry/exit"
  28        help
  29          If you say Y here the kernel will use the Meta hardware trace
  30          unit to output information about function entry and exit that
  31          can be used by a debugger for profiling and call-graphs.
  32
  33config METAG_POISON_CATCH_BUFFERS
  34        bool "Poison catch buffer contents on kernel entry"
  35        help
  36          If you say Y here the kernel will write poison data to the
  37          catch buffer registers on kernel entry. This will make any
  38          problem with catch buffer handling much more apparent.
