2008-01-28kbuild: fixup genksyms usage/getoptMike Frysinger
The usage does not mention the "-a,--arch" or "-T,--dump-types" options, so add them. The calls to getopt() seem to mention options that no longer exist (some "k" and "p" thingy) but omits the "h" option which means using '-h' actually triggers the error code path, so update those as well.

2007-10-12kbuild: apply genksyms changesSam Ravnborg
This patch updates the _shipped files for genksyms. See previous patch for actual functional changes. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-10-12kbuild: __extension__ support in genksyms (fix unknown CRC warning)Sam Ravnborg
Recently the __extension__ keyword has been introduced in the kernel. Teach genksyms about this keyword so it can generate correct CRC for exported symbols that uses a symbol marked __extension__. For now only the typedef variant: __extension__ typedef ... is supported. Later we may add more variants as needed. This patch contains the actual source file changes. The following patch will hold modifications to the generated files (*_shipped) and only after the second patch the fix has effect. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-10-12kbuild: fix genksyms MakefileSam Ravnborg
When enabling GENERATE_PARSER the genksyms Makefile failed to create _shipped version of generated files. Modifying keywords.gperf failed to cause a rebuild of genksyms. Fixed by specifying keywowrds .c as explicit prerequisite of the lexer. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-05-07blackfin architectureBryan Wu
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: http://docs.blackfin.uclinux.org/doku.php?id=testing_the_linux_kernel [m.kozlowski@tuxland.pl: balance parenthesis in blackfin header files] Signed-off-by: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Mariusz Kozlowski <m.kozlowski@tuxland.pl> Signed-off-by: Aubrey Li <aubrey.li@analog.com> Signed-off-by: Jie Zhang <jie.zhang@analog.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2006-06-24kbuild: replace abort() with exit(1)Sam Ravnborg
We have had no use of the coredump file for a long time. So just exit(1) and avoid coredumping. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-06-24kbuild: support for %.symtypes filesAndreas Gruenbacher
Here is a patch that adds a new -T option to genksyms for generating dumps of the type definition that makes up the symbol version hashes. This allows to trace modversion changes back to what caused them. The dump format is the name of the type defined, followed by its definition (which is almost C): s#list_head struct list_head { s#list_head * next , * prev ; } The s#, u#, e#, and t# prefixes stand for struct, union, enum, and typedef. The exported symbols do not define types, and thus do not have an x# prefix: nfs4_acl_get_whotype int nfs4_acl_get_whotype ( char * , t#u32 ) The symbol type defintion of a single file can be generated with: make fs/jbd/journal.symtypes If KBUILD_SYMTYPES is defined, all the *.symtypes of all object files that export symbols are generated. The single *.symtypes files can be combined into a single file after a kernel build with a script like the following: for f in $(find -name '*.symtypes' | sort); do f=${f#./} echo "/* ${f%.symtypes}.o */" cat $f echo done \ | sed -e '\:UNKNOWN:d' \ -e 's:[,;] }:}:g' \ -e 's:\([[({]\) :\1:g' \ -e 's: \([])},;]\):\1:g' \ -e 's: $::' \ $f \ | awk ' /^.#/ { if (defined[$1] == $0) { print $1 next } defined[$1] = $0 } { print } ' When the kernel ABI changes, diffing individual *.symtype files, or the combined files, against each other will show which symbol changes caused the ABI changes. This can save a tremendous amount of time. Dump the types that make up modversions Signed-off-by: Andreas Gruenbacher <agruen@suse.de> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2006-03-20[PATCH] add EXPORT_SYMBOL_GPL_FUTURE()Greg Kroah-Hartman
This patch adds the ability to mark symbols that will be changed in the future, so that kernel modules that don't include MODULE_LICENSE("GPL") and use the symbols, will be flagged and printed out to the system log. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-03-12kbuild: fix genksyms build errorSam Ravnborg
genksyms needs to know when a symbol must have a "_" prefex as is true for a few architectures. Pass $(ARCH) as commandline argument and hardcode what architectures that needs this info. Previous attemt to take it from elfconfig.h was br0ken since elfconfig.h is a generated file. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-03-08kbuild: Fix bug in crc symbol generating of kernel and modulesLuke Yang
The scripts/genksyms/genksyms.c uses hardcoded "__crc_" prefix for crc symbols in kernel and modules. The prefix should be replaced by "MODULE_SYMBOL_PREFIX##__crc_" otherwise there will be warnings when MODULE_SYMBOL_PREFIX is not NULL. I am sorry my last patch for this issue is actually wrong. I revert it in this patch. Signed-off-by: Luke Yang <luke.adi@gmail.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2005-12-26kbuild: Fix genksyms handling of DEFINE_PER_CPU(struct foo_s *, bar);Robin Holt
This is a one-line change to parse.y. To take advantage of this the scripts/genksyms/*_shipped files needs to be rebuild - this is the next patch. When a .c file contains: DEFINE_PER_CPU(struct foo_s *, bar); the .cpp output looks like: __attribute__((__section__(".data.percpu"))) __typeof__(struct foo_s *) per_cpu__bar; With the existing parse.y, the value inside the paranthesis of __typeof__() does not evaluate as a type_specifier and therefore per_cpu__bar does not get assigned a type for genksyms which results in the EXPORT_PER_CPU_SYMBOL() not generating a CRC value. I have compared the Modules.symvers with and without this patch and for ia64's defconfig, the only change is: Before 0x00000000 per_cpu____sn_nodepda vmlinux After 0x9d3f3faa per_cpu____sn_nodepda vmlinux per_cpu____sn_nodepda was the original source of my problems.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
