- menu "Kernel hacking"

- config DEBUG_ERRORS
- bool "Verbose kernel error messages"
- depends on DEBUG_KERNEL
- help
- This option controls verbose debugging information which can be
- printed when the kernel detects an internal error. This debugging
- information is useful to kernel hackers when tracking down problems,
- but mostly meaningless to other people. It's safe to say Y unless
- you are concerned with the code size or don't want to see these
- messages.
- config DEBUG_STACK_USAGE
- bool "Enable 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 output.
- config EARLY_PRINTK
- bool "Early printk support"
- default y
- help
- Say Y here if you want to have an early console using the
- earlyprintk=<name>[,<addr>][,<options>] kernel parameter. It
- is assumed that the early console device has been initialised
- by the boot loader prior to starting the Linux kernel.
- config PID_IN_CONTEXTIDR
- bool "Write the current PID to the CONTEXTIDR register"
- help
- Enabling this option causes the kernel to write the current PID to
- the CONTEXTIDR register, at the expense of some additional
- instructions during context switch. Say Y here only if you are
- planning to use hardware trace tools with this kernel.
