config CMDLINE
	string "Built-in kernel command line"
	help
	  For most platforms, the arguments for the kernel's command line
	  are provided at run-time, during boot. However, there are cases
	  where either no arguments are being provided or the provided
	  arguments are insufficient or even invalid.

	  When that occurs, it is possible to define a built-in command
	  line here and choose how the kernel should use it later on.

choice
	prompt "Kernel command line type"
	default CMDLINE_BOOTLOADER
	help
	  Choose how the kernel will handle the provided built-in command
	  line.

config CMDLINE_BOOTLOADER
	bool "Use bootloader kernel arguments if available"
	help
	  Prefer the command-line passed by the boot loader if available.
	  Use the built-in command line as fallback in case we get nothing
	  during boot. This is the default behaviour.

config CMDLINE_EXTEND
	bool "Use built-in to extend bootloader kernel arguments"
	help
	  The command-line arguments provided during boot will be
	  appended to the built-in command line. This is useful in
	  cases where the provided arguments are insufficient and
	  you don't want to or cannot modify them.

config CMDLINE_FORCE
	bool "Always use the built-in kernel command string"
	help
	  Always use the built-in command line, even if we get one during
	  boot. This is useful in case you need to override the provided
	  command line on systems where you don't have or want control
	  over it.

config BUILTIN_DTB

	help
	  Some existing systems do not provide a canonical device tree to
	  the kernel at boot time. Let's provide a device tree table in the
	  kernel, keyed by the dts filename, containing the relevant DTBs.

	  Built-in DTBs are generic enough and can be used as references.

config BUILTIN_DTB_NAME
	string "Source file for built-in dtb"
	depends on BUILTIN_DTB
	help
	  Base name (without suffix, relative to arch/loongarch/boot/dts/)

	  the kernel.

config DMI
	bool "Enable DMI scanning"
	select DMI_SCAN_MACHINE_NON_EFI_FALLBACK

	  DMI to identify machine quirks.

config EFI

	default y
	depends on EFI
	select EFI_GENERIC_STUB
	help
	  This kernel feature allows the kernel to be loaded directly by
	  EFI firmware without the use of a bootloader.

config SCHED_SMT
	bool "SMT scheduler support"
	default y
	help
	  Improves scheduler's performance when there are multiple
	  threads in one physical core.

config SMP
	bool "Multi-Processing support"
	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.

	  If you say N here, the kernel will run on uni- and multiprocessor
	  machines, but will use only one CPU of a multiprocessor machine. If
	  you say Y here, the kernel will run on many, but not all,
	  uniprocessor machines. On a uniprocessor machine, the kernel
	  will run faster if you say N here.

	  See also the SMP-HOWTO available at <http://www.tldp.org/docs.html#howto>.

	  If you don't know what to do here, say N.

config HOTPLUG_CPU
	bool "Support for hot-pluggable CPUs"
	depends on SMP
	select GENERIC_IRQ_MIGRATION
	help
	  Say Y here to allow turning CPUs off and on. CPUs can be
	  controlled through /sys/devices/system/cpu.
	  (Note: power management support will enable this option
	    automatically on SMP systems. )
	  Say N if you want to disable CPU hotplug.

config NR_CPUS
	int "Maximum number of CPUs (2-256)"
	range 2 256
	depends on SMP

	help
	  This allows you to specify the maximum number of CPUs which this
	  kernel will support.

config NUMA
	bool "NUMA Support"
	select SMP
	select ACPI_NUMA if ACPI
	help
	  Say Y to compile the kernel with NUMA (Non-Uniform Memory Access)
	  support.  This option improves performance on systems with more
	  than one NUMA node; on single node systems it is generally better
	  to leave it disabled.

config ARCH_FORCE_MAX_ORDER
	int "Maximum zone order"
	default "13" if PAGE_SIZE_64KB

	default "10"
	help
	  The kernel memory allocator divides physically contiguous memory
	  blocks into "zones", where each zone is a power of two number of
	  pages.  This option selects the largest power of two that the kernel
	  keeps in the memory allocator.  If you need to allocate very large
	  blocks of physically contiguous memory, then you may need to
	  increase this value.

	  The page size is not necessarily 4KB.  Keep this in mind
	  when choosing a value for this option.

config ARCH_IOREMAP
	bool "Enable LoongArch DMW-based ioremap()"
	help
	  We use generic TLB-based ioremap() by default since it has page
	  protection support. However, you can enable LoongArch DMW-based
	  ioremap() for better performance.

config ARCH_WRITECOMBINE
	bool "Enable WriteCombine (WUC) for ioremap()"
	help
	  LoongArch maintains cache coherency in hardware, but when paired
	  with LS7A chipsets the WUC attribute (Weak-ordered UnCached, which
	  is similar to WriteCombine) is out of the scope of cache coherency
	  machanism for PCIe devices (this is a PCIe protocol violation, which
	  may be fixed in newer chipsets).

	  This means WUC can only used for write-only memory regions now, so
	  this option is disabled by default, making WUC silently fallback to
	  SUC for ioremap(). You can enable this option if the kernel is ensured
	  to run on hardware without this bug.

	  You can override this setting via writecombine=on/off boot parameter.

config ARCH_STRICT_ALIGN
	bool "Enable -mstrict-align to prevent unaligned accesses" if EXPERT
	default y
	help
	  Not all LoongArch cores support h/w unaligned access, we can use
	  -mstrict-align build parameter to prevent unaligned accesses.

	  CPUs with h/w unaligned access support:
	  Loongson-2K2000/2K3000/3A5000/3C5000/3D5000.

	  CPUs without h/w unaligned access support:
	  Loongson-2K500/2K1000.

	  This option is enabled by default to make the kernel be able to run
	  on all LoongArch systems. But you can disable it manually if you want
	  to run kernel only on systems with h/w unaligned access support in
	  order to optimise for performance.

config CPU_HAS_FPU
	bool
	default y

config CPU_HAS_LSX
	bool "Support for the Loongson SIMD Extension"
	depends on AS_HAS_LSX_EXTENSION
	help
	  Loongson SIMD Extension (LSX) introduces 128 bit wide vector registers
	  and a set of SIMD instructions to operate on them. When this option
	  is enabled the kernel will support allocating & switching LSX
	  vector register contexts. If you know that your kernel will only be
	  running on CPUs which do not support LSX or that your userland will
	  not be making use of it then you may wish to say N here to reduce
	  the size & complexity of your kernel.

	  If unsure, say Y.

config CPU_HAS_LASX
	bool "Support for the Loongson Advanced SIMD Extension"
	depends on CPU_HAS_LSX
	depends on AS_HAS_LASX_EXTENSION
	help
	  Loongson Advanced SIMD Extension (LASX) introduces 256 bit wide vector
	  registers and a set of SIMD instructions to operate on them. When this
	  option is enabled the kernel will support allocating & switching LASX
	  vector register contexts. If you know that your kernel will only be
	  running on CPUs which do not support LASX or that your userland will
	  not be making use of it then you may wish to say N here to reduce
	  the size & complexity of your kernel.

	  If unsure, say Y.

config CPU_HAS_LBT
	bool "Support for the Loongson Binary Translation Extension"
	depends on AS_HAS_LBT_EXTENSION
	help
	  Loongson Binary Translation (LBT) introduces 4 scratch registers (SCR0
	  to SCR3), x86/ARM eflags (eflags) and x87 fpu stack pointer (ftop).
	  Enabling this option allows the kernel to allocate and switch registers
	  specific to LBT.

config RANDOMIZE_BASE

	help
	   Randomizes the physical and virtual address at which the
	   kernel image is loaded, as a security feature that
	   deters exploit attempts relying on knowledge of the location
	   of kernel internals.

	   The kernel will be offset by up to RANDOMIZE_BASE_MAX_OFFSET.
