5	---help---
6	  ELF (Executable and Linkable Format) is a format for libraries and
7	  executables used across different architectures and operating
8	  systems. Saying Y here will enable your kernel to run ELF binaries
9	  and enlarge it by about 13 KB. ELF support under Linux has now all
10	  but replaced the traditional Linux a.out formats (QMAGIC and ZMAGIC)
11	  because it is portable (this does *not* mean that you will be able
12	  to run executables from different architectures or operating systems
13	  however) and makes building run-time libraries very easy. Many new
14	  executables are distributed solely in ELF format. You definitely
15	  want to say Y here.
16
17	  Information about ELF is contained in the ELF HOWTO available from
18	  <http://www.tldp.org/docs.html#howto>.
19
20	  If you find that after upgrading from Linux kernel 1.2 and saying Y
21	  here, you still can't run any ELF binaries (they just crash), then
22	  you'll have to install the newest ELF runtime libraries, including
23	  ld.so (check the file <file:Documentation/Changes> for location and
24	  latest version).

35	default y
36	depends on (FRV || BLACKFIN || (SUPERH32 && !MMU) || C6X)
37	help
38	  ELF FDPIC binaries are based on ELF, but allow the individual load
39	  segments of a binary to be located in memory independently of each
40	  other. This makes this format ideal for use in environments where no
41	  MMU is available as it still permits text segments to be shared,
42	  even if data segments are not.
43
44	  It is also possible to run FDPIC ELF binaries on MMU linux also.
45
46config CORE_DUMP_DEFAULT_ELF_HEADERS
47	bool "Write ELF core dumps with partial segments"
48	default y
49	depends on BINFMT_ELF && ELF_CORE
50	help
51	  ELF core dump files describe each memory mapping of the crashed
52	  process, and can contain or omit the memory contents of each one.
53	  The contents of an unmodified text mapping are omitted by default.
54
55	  For an unmodified text mapping of an ELF object, including just
56	  the first page of the file in a core dump makes it possible to
57	  identify the build ID bits in the file, without paying the i/o
58	  cost and disk space to dump all the text.  However, versions of
59	  GDB before 6.7 are confused by ELF core dump files in this format.
60
61	  The core dump behavior can be controlled per process using
62	  the /proc/PID/coredump_filter pseudo-file; this setting is
63	  inherited.  See Documentation/filesystems/proc.txt for details.
64
65	  This config option changes the default setting of coredump_filter
66	  seen at boot time.  If unsure, say Y.
67
68config BINFMT_SCRIPT
69	tristate "Kernel support for scripts starting with #!"
70	default y
71	help
72	  Say Y here if you want to execute interpreted scripts starting with
73	  #! followed by the path to an interpreter.
74
75	  You can build this support as a module; however, until that module
76	  gets loaded, you cannot run scripts.  Thus, if you want to load this
77	  module from an initramfs, the portion of the initramfs before loading
78	  this module must consist of compiled binaries only.
79
80	  Most systems will not boot if you say M or N here.  If unsure, say Y.

82config BINFMT_FLAT

104config BINFMT_AOUT
105	tristate "Kernel support for a.out and ECOFF binaries"
106	depends on HAVE_AOUT
107	---help---
108	  A.out (Assembler.OUTput) is a set of formats for libraries and
109	  executables used in the earliest versions of UNIX.  Linux used
110	  the a.out formats QMAGIC and ZMAGIC until they were replaced
111	  with the ELF format.
112
113	  The conversion to ELF started in 1995.  This option is primarily
114	  provided for historical interest and for the benefit of those
115	  who need to run binaries from that era.
116
117	  Most people should answer N here.  If you think you may have
118	  occasional use for this format, enable module support above
119	  and answer M here to compile this support as a module called
120	  binfmt_aout.
121
122	  If any crucial components of your system (such as /sbin/init
123	  or /lib/ld.so) are still in a.out format, you will have to
124	  say Y here.
125
126config OSF4_COMPAT

128	depends on ALPHA && BINFMT_AOUT
129	help
130	  Say Y if you are using OSF/1 binaries (like Netscape and Acrobat)
131	  with v4 shared libraries freely available from Compaq. If you're
132	  going to use shared libraries from Tru64 version 5.0 or later, say N.
133
134config BINFMT_EM86
135	tristate "Kernel support for Linux/Intel ELF binaries"
136	depends on ALPHA
137	---help---
138	  Say Y here if you want to be able to execute Linux/Intel ELF
139	  binaries just like native Alpha binaries on your Alpha machine. For
140	  this to work, you need to have the emulator /usr/bin/em86 in place.
141
142	  You can get the same functionality by saying N here and saying Y to
143	  "Kernel support for MISC binaries".
144
145	  You may answer M to compile the emulation support as a module and
146	  later load the module when you want to use a Linux/Intel binary. The
147	  module will be called binfmt_em86. If unsure, say Y.
148
149config BINFMT_MISC
150	tristate "Kernel support for MISC binaries"
151	---help---
152	  If you say Y here, it will be possible to plug wrapper-driven binary
153	  formats into the kernel. You will like this especially when you use
154	  programs that need an interpreter to run like Java, Python, .NET or
155	  Emacs-Lisp. It's also useful if you often run DOS executables under
156	  the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO, available from
157	  <http://www.tldp.org/docs.html#howto>). Once you have
158	  registered such a binary class with the kernel, you can start one of
159	  those programs simply by typing in its name at a shell prompt; Linux
160	  will automatically feed it to the correct interpreter.
161
162	  You can do other nice things, too. Read the file
163	  <file:Documentation/binfmt_misc.txt> to learn how to use this
164	  feature, <file:Documentation/java.txt> for information about how
165	  to include Java support. and <file:Documentation/mono.txt> for
166          information about how to include Mono-based .NET support.
167
168          To use binfmt_misc, you will need to mount it:
169		mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc
170
171	  You may say M here for module support and later load the module when
172	  you have use for it; the module is called binfmt_misc. If you
173	  don't know what to answer at this point, say Y.
174
175config COREDUMP
176	bool "Enable core dump support" if EXPERT
177	default y
178	help
179	  This option enables support for performing core dumps. You almost
180	  certainly want to say Y here. Not necessary on systems that never
181	  need debugging or only ever run flawless code.
