Symbol: CONFIG_PRINTK_TIME Help: Selecting this option causes time stamps of the printk() messages to be added to the output of the syslog() system call and at the console. The timestamp is always recorded internally, and exported to /dev/kmsg. This flag just specifies if the timestamp should be included, not that the timestamp is recorded. The behavior is also controlled by the kernel command line parameter printk.time=1. See Documentation/admin-guide/kernel-parameters.rst Type: boolean Choice: built-in [*] Reason: It's highly recommended that you include this option in your kernel as timestamps add another level of precision to your system logs.
Symbol: CONFIG_CONSOLE_LOGLEVEL_DEFAULT Help: Default loglevel to determine what will be printed on the console. Setting a default here is equivalent to passing in loglevel=<x> in the kernel bootargs. loglevel=<x> continues to override whatever value is specified here as well. Note: This does not affect the log level of un-prefixed printk() usage in the kernel. That is controlled by the MESSAGE_LOGLEVEL_DEFAULT option. Type: integer Choice: (15) custom Reason: It's recommended that you set the value of this option to a value that ensures enough verbosity is being used. If you've already excluded a bunch of debugging options to minimize system overhead, then you'd likely want to set the value of this option and CONFIG_MESSAGE_LOGLEVEL_DEFAULT to a high enough value to get enough information.
Symbol: CONFIG_MESSAGE_LOGLEVEL_DEFAULT Help: Default log level for printk statements with no specified priority. This was hard-coded to KERN_WARNING since at least 2.6.10 but folks that are auditing their logs closely may want to set it to a lower priority. Note: This does not affect what message level gets printed on the console by default. To change that, use loglevel=<x> in the kernel bootargs, or pick a different CONSOLE_LOGLEVEL_DEFAULT configuration value. Type: integer Choice: (7) custom Reason: It's recommended that you set the value of this option to a value that ensures enough verbosity is being used. If you've already excluded a bunch of debugging options to minimize system overhead, then you'd likely want to set the value of this option and CONFIG_CONSOLE_LOGLEVEL_DEFAULT to a high enough value to get enough information.
Symbol: CONFIG_FRAME_WARN Help: Tell gcc to warn at build time for stack frames larger than this. Setting this too low will cause a lot of warnings. Setting it to 0 disables the warning. Requires gcc 4.4 Type: integer Choice: (0) custom Reason: If you can live with the warnings then don't disable this option.
Symbol: CONFIG_DEBUG_KERNEL Help: Say Y here if you are developing drivers or trying to debug and identify kernel problems. Type: boolean Choice: built-in -*- Reason: Forcibly included by CONFIG_EXPERT.
Symbol: CONFIG_PANIC_TIMEOUT Help: Set the timeout value (in seconds) until a reboot occurs when the the kernel panics. If n = 0, then we wait forever. A timeout value n > 0 will wait n seconds before rebooting, while a timeout value n < 0 will reboot immediately. Type: integer Choice: (0) custom Reason: Setting the value of this option to (0) will give you all the time you want to carefully examine the cause of the kernel panic.
Symbol: CONFIG_RCU_CPU_STALL_TIMEOUT Help: If a given RCU grace period extends more than the specified number of seconds, a CPU stall warning is printed. If the RCU grace period persists, additional CPU stall warnings are printed at more widely spaced intervals. Type: integer Choice: (3) custom
Symbol: CONFIG_IO_DELAY_NONE Help: No port-IO delay. Will break on old boxes that require port-IO delay for certain operations. Should work on most new machines. Type: boolean Choice: built-in (X) Reason: It's highly recommended that you include this option in your kernel if you're on a modern system.
