+# X86
+config EARLY_PRINTK
+ bool "Early printk" if EMBEDDED && DEBUG_KERNEL
+ default y
+ depends on X86
+ help
+ Write kernel log output directly into the VGA buffer or to a serial
+ port.
+
+ This is useful for kernel debugging when your machine crashes very
+ early before the console code is initialized. 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 && X86
+
+config KPROBES
+ bool "Kprobes"
+ depends on DEBUG_KERNEL && X86
+ 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 && X86
+ 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 && X86
+
+config DEBUG_PAGEALLOC
+ bool "Page alloc debugging"
+ depends on DEBUG_KERNEL && !SOFTWARE_SUSPEND && X86
+ 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 && X86
+ 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 && X86
+ default y
+
+config X86_MPPARSE
+ bool
+ depends on X86_LOCAL_APIC && !X86_VISWS && X86
+ default y
+
+# X86_64
+
+# !SMP for now because the context switch early causes GPF in segment reloading
+# and the GS base checking does the wrong thing then, causing a hang.
+config CHECKING
+ bool "Additional run-time checks"
+ depends on DEBUG_KERNEL && !SMP && X86_64
+ help
+ Enables some internal consistency checks for kernel debugging.
+ You should normally say N.
+
+config INIT_DEBUG
+ bool "Debug __init statements"
+ depends on DEBUG_KERNEL && X86_64
+ help
+ Fill __init and __initdata at the end of boot. This helps debugging
+ illegal uses of __init and __initdata after initialization.
+
+config IOMMU_DEBUG
+ depends on GART_IOMMU && DEBUG_KERNEL && X86_64
+ bool "Enable IOMMU debugging"
+ help
+ Force the IOMMU to on even when you have less than 4GB of
+ memory and add debugging code. On overflow always panic. And
+ allow to enable IOMMU leak tracing. Can be disabled at boot
+ time with iommu=noforce. This will also enable scatter gather
+ list merging. Currently not recommended for production
+ code. When you use it make sure you have a big enough
+ IOMMU/AGP aperture. Most of the options enabled by this can
+ be set more finegrained using the iommu= command line
+ options. See Documentation/x86_64/boot-options.txt for more
+ details.
+
+config IOMMU_LEAK
+ bool "IOMMU leak tracing"
+ depends on DEBUG_KERNEL && X86_64
+ depends on IOMMU_DEBUG
+ help
+ Add a simple leak tracer to the IOMMU code. This is useful when you
+ are debugging a buggy device driver that leaks IOMMU mappings.
+
+#config X86_REMOTE_DEBUG
+# bool "kgdb debugging stub"
+
+# X86 & X86_64
+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".
