	depends on !KASAN || KASAN_VMALLOC

	---help---

	help

	  Enable this if you want the use virtually-mapped kernel stacks

	  with guard pages.  This causes kernel stack overflows to be

	  caught immediately rather than causing difficult-to-diagnose

config LOCK_EVENT_COUNTS

	bool "Locking event counts collection"

	depends on DEBUG_FS

	---help---

	help

	  Enable light-weight counting of various locking related events

	  in the system with minimal performance impact. This reduces

	  the chance of application behavior change because of timing

choice

	prompt "Alpha system type"

	default ALPHA_GENERIC

	---help---

	help

	  This is the system type of your hardware.  A "generic" kernel will

	  run on any supported Alpha system. However, if you configure a

	  kernel for your specific system, it will be faster and smaller.

config ALPHA_QEMU

	bool "Run under QEMU emulation"

	depends on !ALPHA_GENERIC

	---help---

	help

	  Assume the presence of special features supported by QEMU PALcode

	  that reduce the overhead of system emulation.

	---help---

	help

	  There are two different types of booting firmware on Alphas: SRM,

	  which is command line driven, and ARC, which uses menus and arrow

	  keys. Details about the Linux/Alpha booting process are contained in

config SMP

	bool "Symmetric multi-processing support"

	depends on ALPHA_SABLE || ALPHA_LYNX || ALPHA_RAWHIDE || ALPHA_DP264 || ALPHA_WILDFIRE || ALPHA_TITAN || ALPHA_GENERIC || ALPHA_SHARK || ALPHA_MARVEL

	---help---

	help

	  This enables support for systems with more than one CPU. If you have

	  a system with only one CPU, say N. If you have a system with more

	  than one CPU, say Y.

	---help---

	help

	  The Wait for Interrupt (WTINT) PALcall attempts to place the CPU

	  to sleep until the next interrupt.  This may reduce the power

	  consumed, and the heat produced by the computer.  However, it has

# LARGE_VMALLOC is racy, if you *really* need it then fix it first

config ALPHA_LARGE_VMALLOC

	bool

	---help---

	help

	  Process creation and other aspects of virtual memory management can

	  be streamlined if we restrict the kernel to one PGD for all vmalloc

	  allocations.  This equates to about 8GB.

	int "Verbose Printing Mode (0=off, 1=on, 2=all)"

	depends on VERBOSE_MCHECK

	default 1

	---help---

	help

	  This option allows the default printing mode to be set, and then

	  possibly overridden by a boot command argument.

	default HZ_128 if ALPHA_QEMU

	default HZ_1200 if ALPHA_RAWHIDE

	default HZ_1024

	---help---

	help

	  The frequency at which timer interrupts occur.  A high frequency

	  minimizes latency, whereas a low frequency minimizes overhead of

	  process accounting.  The later effect is especially significant

config SRM_ENV

	tristate "SRM environment through procfs"

	depends on PROC_FS

	---help---

	help

	  If you enable this option, a subdirectory inside /proc called

	  /proc/srm_environment will give you access to the all important

	  SRM environment variables (those which have a name) and also

	bool "Legacy kernel start address"

	depends on ALPHA_GENERIC

	default n

	---help---

	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

	depends on NEED_MULTIPLE_NODES

	---help---

	help

	  Accessing memory beyond 1GB (with or w/o PAE) requires 2 memory

	  zones.
