1 config BINFMT_ELF
2         bool "Kernel support for ELF binaries"
3         depends on MMU
4         default y
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).

26 config BINFMT_FLAT
27         tristate "Kernel support for flat binaries"
28         depends on !MMU || SUPERH
29         help
30           Support uClinux FLAT format binaries.
31
32 config BINFMT_ZFLAT
33         bool "Enable ZFLAT support"
34         depends on BINFMT_FLAT
35         select ZLIB_INFLATE
36         help
37           Support FLAT format compressed binaries
38
39 config BINFMT_SHARED_FLAT
40         bool "Enable shared FLAT support"
41         depends on BINFMT_FLAT
42         help
43           Support FLAT shared libraries
44
45 config BINFMT_AOUT
46         tristate "Kernel support for a.out and ECOFF binaries"
47         depends on (X86 && !X86_64) || ALPHA || ARM || M68K || SPARC32
48         ---help---
49           A.out (Assembler.OUTput) is a set of formats for libraries and
50           executables used in the earliest versions of UNIX.  Linux used
51           the a.out formats QMAGIC and ZMAGIC until they were replaced
52           with the ELF format.
53
54           The conversion to ELF started in 1995.  This option is primarily
55           provided for historical interest and for the benefit of those
56           who need to run binaries from that era.
57
58           Most people should answer N here.  If you think you may have
59           occasional use for this format, enable module support above
60           and answer M here to compile this support as a module called
61           binfmt_aout.
62
63           If any crucial components of your system (such as /sbin/init
64           or /lib/ld.so) are still in a.out format, you will have to
65           say Y here.
66
67 config OSF4_COMPAT
68         bool "OSF/1 v4 readv/writev compatibility"
69         depends on ALPHA && BINFMT_AOUT
70         help
71           Say Y if you are using OSF/1 binaries (like Netscape and Acrobat)
72           with v4 shared libraries freely available from Compaq. If you're
73           going to use shared libraries from Tru64 version 5.0 or later, say N.
74
75 config BINFMT_EM86
76         tristate "Kernel support for Linux/Intel ELF binaries"
77         depends on ALPHA
78         ---help---
79           Say Y here if you want to be able to execute Linux/Intel ELF
80           binaries just like native Alpha binaries on your Alpha machine. For
81           this to work, you need to have the emulator /usr/bin/em86 in place.
82
83           You can get the same functionality by saying N here and saying Y to
84           "Kernel support for MISC binaries".
85
86           You may answer M to compile the emulation support as a module and
87           later load the module when you want to use a Linux/Intel binary. The
88           module will be called binfmt_em86. If unsure, say Y.
89
90 config BINFMT_SOM
91         tristate "Kernel support for SOM binaries"
92         depends on PARISC && HPUX
93         help
94           SOM is a binary executable format inherited from HP/UX.  Say
95           Y here to be able to load and execute SOM binaries directly.
96
97 config BINFMT_MISC
98         tristate "Kernel support for MISC binaries"
99         ---help---
100           If you say Y here, it will be possible to plug wrapper-driven binary
101           formats into the kernel. You will like this especially when you use
102           programs that need an interpreter to run like Java, Python, .NET or
103           Emacs-Lisp. It's also useful if you often run DOS executables under
104           the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO, available from
105           <http://www.tldp.org/docs.html#howto>). Once you have
106           registered such a binary class with the kernel, you can start one of
107           those programs simply by typing in its name at a shell prompt; Linux
108           will automatically feed it to the correct interpreter.
109
110           You can do other nice things, too. Read the file
111           <file:Documentation/binfmt_misc.txt> to learn how to use this
112           feature, <file:Documentation/java.txt> for information about how
113           to include Java support. and <file:Documentation/mono.txt> for
114           information about how to include Mono-based .NET support.
115
116           To use binfmt_misc, you will need to mount it:
117                 mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc
118
119           You may say M here for module support and later load the module when
120           you have use for it; the module is called binfmt_misc. If you
121           don't know what to answer at this point, say Y.
