  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.

  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.

  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.
