+config BINFMT_ELF
+ bool "Kernel support for ELF binaries"
+ depends on MMU
+ select ELFCORE
+ default y
+ help
+ ELF (Executable and Linkable Format) is a format for libraries and
+ executables used across different architectures and operating
+ systems. Saying Y here will enable your kernel to run ELF binaries
+ and enlarge it by about 13 KB. ELF support under Linux has now all
+ but replaced the traditional Linux a.out formats (QMAGIC and ZMAGIC)
+ because it is portable (this does *not* mean that you will be able
+ to run executables from different architectures or operating systems
+ however) and makes building run-time libraries very easy. Many new
+ executables are distributed solely in ELF format. You definitely
+ want to say Y here.
+
+ Information about ELF is contained in the ELF HOWTO available from
+ <http://www.tldp.org/docs.html#howto>.
+
+ If you find that after upgrading from Linux kernel 1.2 and saying Y
+ here, you still can't run any ELF binaries (they just crash), then
+ you'll have to install the newest ELF runtime libraries, including
+ ld.so (check the file <file:Documentation/Changes> for location and
+ latest version).
+
+config BINFMT_ELF_KUNIT_TEST
+ bool "Build KUnit tests for ELF binary support" if !KUNIT_ALL_TESTS
+ depends on KUNIT=y && BINFMT_ELF=y
+ default KUNIT_ALL_TESTS
+ help
+ This builds the ELF loader KUnit tests, which try to gather
+ prior bug fixes into a regression test collection. This is really
+ only needed for debugging. Note that with CONFIG_COMPAT=y, the
+ compat_binfmt_elf KUnit test is also created.

+ bool "Kernel support for FDPIC ELF binaries"
+ default y if !BINFMT_ELF
+ depends on ARM || ((M68K || RISCV || SUPERH || XTENSA) && !MMU)
+ select ELFCORE
+ help
+ ELF FDPIC binaries are based on ELF, but allow the individual load
+ segments of a binary to be located in memory independently of each
+ other. This makes this format ideal for use in environments where no
+ MMU is available as it still permits text segments to be shared,
+ even if data segments are not.
+
+ It is also possible to run FDPIC ELF binaries on MMU linux also.
+
+config ELFCORE
+ bool
+ help
+ This option enables kernel/elfcore.o.
+
+config CORE_DUMP_DEFAULT_ELF_HEADERS
+ bool "Write ELF core dumps with partial segments"
+ default y
+ depends on BINFMT_ELF && ELF_CORE
+ help
+ ELF core dump files describe each memory mapping of the crashed
+ process, and can contain or omit the memory contents of each one.
+ The contents of an unmodified text mapping are omitted by default.
+
+ For an unmodified text mapping of an ELF object, including just
+ the first page of the file in a core dump makes it possible to
+ identify the build ID bits in the file, without paying the i/o
+ cost and disk space to dump all the text. However, versions of
+ GDB before 6.7 are confused by ELF core dump files in this format.
+
+ The core dump behavior can be controlled per process using
+ the /proc/PID/coredump_filter pseudo-file; this setting is
+ inherited. See Documentation/filesystems/proc.rst for details.
+
+ This config option changes the default setting of coredump_filter
+ seen at boot time. If unsure, say Y.
+
+config BINFMT_SCRIPT
+ tristate "Kernel support for scripts starting with #!"
+ default y
+ help
+ Say Y here if you want to execute interpreted scripts starting with
+ #! followed by the path to an interpreter.
+
+ You can build this support as a module; however, until that module
+ gets loaded, you cannot run scripts. Thus, if you want to load this
+ module from an initramfs, the portion of the initramfs before loading
+ this module must consist of compiled binaries only.
+
+ Most systems will not boot if you say M or N here. If unsure, say Y.

+
+config BINFMT_ZFLAT
+ bool "Enable ZFLAT support"
+ depends on BINFMT_FLAT
+ select ZLIB_INFLATE
+ help
+ Support FLAT format compressed binaries
+
+config BINFMT_MISC
+ tristate "Kernel support for MISC binaries"
+ help
+ If you say Y here, it will be possible to plug wrapper-driven binary
+ formats into the kernel. You will like this especially when you use
+ programs that need an interpreter to run like Java, Python, .NET or
+ Emacs-Lisp. It's also useful if you often run DOS executables under
+ the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO, available from
+ <http://www.tldp.org/docs.html#howto>). Once you have
+ registered such a binary class with the kernel, you can start one of
+ those programs simply by typing in its name at a shell prompt; Linux
+ will automatically feed it to the correct interpreter.
+
+ You can do other nice things, too. Read the file
+ <file:Documentation/admin-guide/binfmt-misc.rst> to learn how to use this
+ feature, <file:Documentation/admin-guide/java.rst> for information about how
+ to include Java support. and <file:Documentation/admin-guide/mono.rst> for
+ information about how to include Mono-based .NET support.
+
+ To use binfmt_misc, you will need to mount it:
+ mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc
+
+ You may say M here for module support and later load the module when
+ you have use for it; the module is called binfmt_misc. If you
+ don't know what to answer at this point, say Y.
+
+config BINFMT_MISC_BPF
+ bool "BPF-selected interpreters for misc binaries"
+ depends on BINFMT_MISC=y
+ depends on BPF_SYSCALL && BPF_JIT && DEBUG_INFO_BTF
+ help
+ Allow binfmt_misc binary type handlers to be implemented as bpf
+ struct_ops programs. Instead of matching a fixed magic and
+ redirecting to a fixed interpreter recorded at registration time
+ such handlers match binaries programmatically and compute the
+ interpreter to use per binary, e.g. relative to the location of
+ the binary itself.
+
+ If you don't know what to answer at this point, say N.
+
+config COREDUMP
+ bool "Enable core dump support" if EXPERT
+ default y
+ help
+ This option enables support for performing core dumps. You almost
+ certainly want to say Y here. Not necessary on systems that never
+ need debugging or only ever run flawless code.
+
+config EXEC_KUNIT_TEST
+ bool "Build execve tests" if !KUNIT_ALL_TESTS
+ depends on KUNIT=y
+ default KUNIT_ALL_TESTS
+ help
+ This builds the exec KUnit tests, which tests boundary conditions
+ of various aspects of the exec internals.
+
+config ARCH_HAS_ELF_CORE_EFLAGS
+ bool
+ depends on BINFMT_ELF && ELF_CORE
+ default n
+ help
+ Select this option if the architecture makes use of the e_flags
+ field in the ELF header to store ABI or other architecture-specific
+ information that should be preserved in core dumps.
