   6         bool

   9 config DEBUG_ERRORS
  10         bool "Verbose kernel error messages"
  11         depends on DEBUG_KERNEL
  12         help
  13           This option controls verbose debugging information which can be
  14           printed when the kernel detects an internal error. This debugging
  15           information is useful to kernel hackers when tracking down problems,
  16           but mostly meaningless to other people. It's safe to say Y unless
  17           you are concerned with the code size or don't want to see these
  18           messages.

  20 config DEBUG_STACK_USAGE
  21         bool "Enable stack utilization instrumentation"
  22         depends on DEBUG_KERNEL
  23         help
  24           Enables the display of the minimum amount of free stack which each
  25           task has ever had available in the sysrq-T output.

  27 config EARLY_PRINTK
  28         bool "Early printk support"
  29         default y
  30         help
  31           Say Y here if you want to have an early console using the
  32           earlyprintk=<name>[,<addr>][,<options>] kernel parameter. It
  33           is assumed that the early console device has been initialised
  34           by the boot loader prior to starting the Linux kernel.
  35
  36 config PID_IN_CONTEXTIDR
  37         bool "Write the current PID to the CONTEXTIDR register"
  38         help
  39           Enabling this option causes the kernel to write the current PID to
  40           the CONTEXTIDR register, at the expense of some additional
  41           instructions during context switch. Say Y here only if you are
  42           planning to use hardware trace tools with this kernel.
