menu "Kernel hacking" source "lib/Kconfig.debug" config EARLY_PRINTK bool depends on ALPHA_GENERIC || ALPHA_SRM default y config ALPHA_LEGACY_START_ADDRESS bool "Legacy kernel start address" depends on ALPHA_GENERIC default n ---help--- The 2.4 kernel changed the kernel start address from 0x310000 to 0x810000 to make room for the Wildfire's larger SRM console. Recent consoles on Titan and Marvel machines also require the extra room. If you're using aboot 0.7 or later, the bootloader will examine the ELF headers to determine where to transfer control. Unfortunately, most older bootloaders -- APB or MILO -- hardcoded the kernel start address rather than examining the ELF headers, and the result is a hard lockup. Say Y if you have a broken bootloader. Say N if you do not, or if you wish to run on Wildfire, Titan, or Marvel. config ALPHA_LEGACY_START_ADDRESS bool depends on !ALPHA_GENERIC && !ALPHA_TITAN && !ALPHA_MARVEL && !ALPHA_WILDFIRE default y 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 Alpha. 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. endmenu
