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.
endchoice
config DMI
bool "Enable DMI scanning"
select DMI_SCAN_MACHINE_NON_EFI_FALLBACK
default y
help
This enables SMBIOS/DMI feature for systems, and scanning of
DMI to identify machine quirks.
config EFI
bool "EFI runtime service support"
select UCS2_STRING
select EFI_PARAMS_FROM_FDT
select EFI_RUNTIME_WRAPPERS
help
This enables the kernel to use EFI runtime services that are
available (such as the EFI variable services).
config FORCE_MAX_ZONEORDER
int "Maximum zone order"
range 14 64 if PAGE_SIZE_64KB
default "14" if PAGE_SIZE_64KB
range 12 64 if PAGE_SIZE_16KB
default "12" if PAGE_SIZE_16KB
range 11 64
default "11"
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.
This config option is actually maximum order plus one. For example,
a value of 11 means that the largest free memory block is 2^10 pages.
The page size is not necessarily 4KB. Keep this in mind
when choosing a value for this option.
config SECCOMP
bool "Enable seccomp to safely compute untrusted bytecode"
depends on PROC_FS
default y
help
This kernel feature is useful for number crunching applications
that may need to compute untrusted bytecode during their
execution. By using pipes or other transports made available to
the process as file descriptors supporting the read/write
syscalls, it's possible to isolate those applications in
their own address space using seccomp. Once seccomp is
enabled via /proc/<pid>/seccomp, it cannot be disabled
and the task is only allowed to execute a few safe syscalls
defined by each seccomp mode.
If unsure, say Y. Only embedded should say N here.

Say Y to support efficient handling of sparse physical memory,
for architectures which are either NUMA (Non-Uniform Memory Access)
or have huge holes in the physical address space for other reasons.
