# SPDX-License-Identifier: GPL-2.0 config EARLY_PRINTK bool "Early printk" if EXPERT depends on SYS_HAS_EARLY_PRINTK default y help This option enables special console drivers which allow the kernel to print messages very early in the bootup process. This is useful for kernel debugging when your machine crashes very early before the console code is initialized. For normal operation, it is not recommended because it looks ugly on some machines and doesn't cooperate with an X server. You should normally say N here, unless you want to debug such a crash. config UNA_PRINT bool "Show debug info about user unalign memory access" default n config MATHEMU tristate "Kernel FP software completion" if DEBUG_KERNEL && !SMP default y if !DEBUG_KERNEL || SMP help This option is required for IEEE compliant floating point arithmetic on the SW. The only time you would ever not say Y is to say M in order to debug the code. Say Y unless you know what you are doing. config STACKTRACE_SUPPORT bool default y config SW64_RRU bool "Enable RRU(Remote Read User)" depends on SW64 default n help Duplicate user stdout and stderr to specific space. Do not enable it in a production kernel. config SW64_RRK bool "Enable RRK(Remote Read Kernel)" depends on SW64 default y help Duplicate kernel log to specific space. Do not enable it in a production kernel.
