menu "Kernel hacking" config [31mCONFIG_TRACE_IRQFLAGS_SUPPORT[0m bool default y source "lib/Kconfig.debug" config [31mCONFIG_4KSTACKS[0m bool "Use 4Kb for kernel stacks instead of 8Kb" depends on [31mCONFIG_DEBUG_KERNEL[0m 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 [31mCONFIG_METAG_FUNCTION_TRACE[0m 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 [31mCONFIG_METAG_POISON_CATCH_BUFFERS[0m 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 |
