-config DEBUG_VERBOSE
- bool "Verbose fault messages"
- default y
- select PRINTK
- help
- When a program crashes due to an exception, or the kernel detects
- an internal error, the kernel can print a not so brief message
- explaining what the problem was. This debugging information is
- useful to developers and kernel hackers when tracking down problems,
- but mostly meaningless to other people. This is always helpful for
- debugging but serves no purpose on a production system.
- Most people should say N here.

-config PROTECT_KERNEL
- default y
- bool 'Enable Kernel range register Protection'
- help
- Adds code to enable/disable range registers to protect static
- kernel code/data from userspace. Currently the ranges covered
- do no protect kernel loadable modules or dynamically allocated
- kernel data.

-config NO_KERNEL_MSG
- bool "Suppress Kernel BUG Messages"
- help
- Do not output any debug BUG messages within the kernel.
-
-config EARLY_PRINTK
- bool "Use the driver that you selected as console also for early printk (to debug kernel bootup)."
- default n
- help
- If you want to use the serdes driver (console=ttyUS0) for
- early printk, you must also supply an additional kernel boot
- parameter like this:
-
- serdes=ioportaddr,irq,clockrate,baud
-
- For an IP7160RGW eval board, you could use this:
-
- serdes=0x2004000,61,250000000,57600
-
- which will let you see early printk output at 57600 baud.

-config DEBUG_IRQMEASURE
- bool "Enable IRQ handler measurements"
- default n
- help
- When enabled each IRQ's min/avg/max times will be printed. If the handler
- re-enables interrupt, the times will show the full time including to service
- nested interrupts. See /proc/irq_measurements.

-config DEBUG_PCIMEASURE
- bool "Enable PCI transaction measurements"
- default n
- help
- When enabled the system will measure the min/avg/max timer for each PCI transactions.
- See /proc/pci_measurements.
-
-config ACCESS_OK_CHECKS_ENABLED
- bool "Enable user space access checks"
- default n
- help
- Enabling this check causes the kernel to verify that addresses passed
- to the kernel by the user space code are within the processes
- address space. On a no-mmu system, this is done by examining the
- processes memory data structures (adversly affecting performance) but
- ensuring that a process does not ask the kernel to violate another
- processes address space. Sadly, the kernel uses access_ok() for
- address that are in the kernel which results in a large volume of
- false positives.

- drops below a certain limit (THREAD_SIZE /8).
-
-config DEBUG_STACK_USAGE
- bool "Stack utilization instrumentation"
- default n
- depends on DEBUG_KERNEL
- help
- Enables the display of the minimum amount of free kernel 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.
