menu "Kernel hacking" config TRACE_IRQFLAGS_SUPPORT bool default y source "lib/Kconfig.debug" 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. endmenu
