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 EARLY_PRINTK_8250 + bool + depends on EARLY_PRINTK && USE_GENERIC_EARLY_PRINTK_8250 + default y + help + "8250/16550 and compatible serial early printk driver" + If you say Y here, it will be possible to use a 8250/16550 serial + port as the boot console. + +config USE_GENERIC_EARLY_PRINTK_8250 + bool + +config CMDLINE_BOOL + bool "Built-in kernel command line" + default n + help + For most systems, it is firmware or second stage bootloader that + by default specifies the kernel command line options. However, + it might be necessary or advantageous to either override the + default kernel command line or add a few extra options to it. + For such cases, this option allows you to hardcode your own + command line options directly into the kernel. For that, you + should choose 'Y' here, and fill in the extra boot arguments + in CONFIG_CMDLINE. + + The built-in options will be concatenated to the default command + line if CMDLINE_OVERRIDE is set to 'N'. Otherwise, the default + command line will be ignored and replaced by the built-in string. + + Most MIPS systems will normally expect 'N' here and rely upon + the command line from the firmware or the second-stage bootloader. + +config CMDLINE + string "Default kernel command string" + depends on CMDLINE_BOOL + default "" + help + On some platforms, there is currently no way for the boot loader to + pass arguments to the kernel. For these platforms, and for the cases + when you want to add some extra options to the command line or ignore + the default command line, you can supply some command-line options at + build time by entering them here. In other cases you can specify + kernel args so that you don't have to set them up in board prom + initialization routines. + + For more information, see the CMDLINE_BOOL and CMDLINE_OVERRIDE + options. + +config CMDLINE_OVERRIDE + bool "Built-in command line overrides firmware arguments" + default n + depends on CMDLINE_BOOL + help + By setting this option to 'Y' you will have your kernel ignore + command line arguments from firmware or second stage bootloader. + Instead, the built-in command line will be used exclusively. + + Normally, you will choose 'N' here. + +config SB1XXX_CORELIS + bool "Corelis Debugger" + depends on SIBYTE_SB1xxx_SOC + select DEBUG_INFO + help + Select compile flags that produce code that can be processed by the + Corelis mksym utility and UDB Emulator. + +config RUNTIME_DEBUG + bool "Enable run-time debugging" + depends on DEBUG_KERNEL + help + If you say Y here, some debugging macros will do run-time checking. + If you say N here, those macros will mostly turn to no-ops.
