For normal operation - it is not recommended because it looks ugly and doesn't cooperate - with klogd/syslogd or the X server. You should normally N here, - unless you want to debug such a crash. - -config DEBUG_STACKOVERFLOW - bool "Check for stack overflows" - depends on DEBUG_KERNEL - help - This option will cause messages to be printed if free stack space - drops below a certain limit. - -config KPROBES - bool "Kprobes" - depends on DEBUG_KERNEL - help - Kprobes allows you to trap at almost any kernel address and - execute a callback function. register_kprobe() establishes - a probepoint and specifies the callback. Kprobes is useful - for kernel debugging, non-intrusive instrumentation and testing. - If in doubt, say "N". - -config DEBUG_STACK_USAGE - bool "Stack utilization instrumentation" - depends on DEBUG_KERNEL - help - Enables the display of the minimum amount of free stack which each - task has ever had available in the sysrq-T and sysrq-P debug output. - - This option will slow down process creation somewhat. - -comment "Page alloc debug is incompatible with Software Suspend on i386" - depends on DEBUG_KERNEL && SOFTWARE_SUSPEND - -config DEBUG_PAGEALLOC - bool "Page alloc debugging" - depends on DEBUG_KERNEL && !SOFTWARE_SUSPEND - help - Unmap pages from the kernel linear mapping after free_pages(). - This results in a large slowdown, but helps to find certain types - of memory corruptions. - -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 X86_FIND_SMP_CONFIG - bool - depends on X86_LOCAL_APIC || X86_VOYAGER - default y - -config X86_MPPARSE - bool - depends on X86_LOCAL_APIC && !X86_VISWS - default y - -endmenu |
