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).

blackfin architecture
This adds support for the Analog Devices Blackfin processor architecture, and
currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561
(Dual Core) devices, with a variety of development platforms including those
avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP,
BF561-EZKIT), and Bluetechnix! Tinyboards.
The Blackfin architecture was jointly developed by Intel and Analog Devices
Inc. (ADI) as the Micro Signal Architecture (MSA) core and introduced it in
December of 2000. Since then ADI has put this core into its Blackfin
processor family of devices. The Blackfin core has the advantages of a clean,
orthogonal,RISC-like microprocessor instruction set. It combines a dual-MAC
(Multiply/Accumulate), state-of-the-art signal processing engine and
single-instruction, multiple-data (SIMD) multimedia capabilities into a single
instruction-set architecture.
The Blackfin architecture, including the instruction set, is described by the
ADSP-BF53x/BF56x Blackfin Processor Programming Reference
http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf
The Blackfin processor is already supported by major releases of gcc, and
there are binary and source rpms/tarballs for many architectures at:
http://blackfin.uclinux.org/gf/project/toolchain/frs There is complete
documentation, including "getting started" guides available at:
http://docs.blackfin.uclinux.org/ which provides links to the sources and
patches you will need in order to set up a cross-compiling environment for
bfin-linux-uclibc
This patch, as well as the other patches (toolchain, distribution,
uClibc) are actively supported by Analog Devices Inc, at:
http://blackfin.uclinux.org/
We have tested this on LTP, and our test plan (including pass/fails) can
be found at:

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.

A.out (Assembler.OUTput) is a set of formats for libraries and
|
|
|
|
executables used in the earliest versions of UNIX. Linux used
|
|
|
|
the a.out formats QMAGIC and ZMAGIC until they were replaced
|
|
|
|
with the ELF format.
|
|
|
|
|
|
|
|
The conversion to ELF started in 1995. This option is primarily
|
|
|
|
provided for historical interest and for the benefit of those
|
|
|
|
who need to run binaries from that era.
|
|
|
|
|
|
|
|
Most people should answer N here. If you think you may have
|
|
|
|
occasional use for this format, enable module support above
|
|
|
|
and answer M here to compile this support as a module called
|
|
|
|
binfmt_aout.
|
|
|
|
|
|
|
|
If any crucial components of your system (such as /sbin/init
|
|
|
|
or /lib/ld.so) are still in a.out format, you will have to
|
|
|
|
say Y here.

Say Y here if you want to be able to execute Linux/Intel ELF

this to work, you need to have the emulator /usr/bin/em86 in place.

You can get the same functionality by saying N here and saying Y to
|
|
|
|
"Kernel support for MISC binaries".
|
|

You may answer M to compile the emulation support as a module and
|

later load the module when you want to use a Linux/Intel binary. The
|
|
|
|
module will be called binfmt_em86. If unsure, say Y.

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/binfmt_misc.txt> to learn how to use this
|
|
|
|
feature, <file:Documentation/java.txt> for information about how
|
|
|
|
to include Java support. and <file:Documentation/mono.txt> 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.
