| 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. |
