b16838c6 - kbuild: trace functions in subdirectories of lib/

Tue, 07 Jul 2020 09:21:17 +0000

kbuild: trace functions in subdirectories of lib/ccflags-remove-$(CONFIG_FUNCTION_TRACER) += $(CC_FLAGS_FTRACE)exists here in sub-directories of lib/ to keep the behavior ofcommit 2464a609ded0 ("ftrace: do not trace library functions").Since that commit, not only the objects in lib/ but also the ones inthe sub-directories are excluded from ftrace (although the commitdescription did not explicitly mention this).However, most of library functions in sub-directories are not so hot.Re-add them to ftrace.Going forward, only the objects right under lib/ will be excluded.Cc: Ingo Molnar Signed-off-by: Masahiro Yamada Acked-by: Steven Rostedt (VMware) List of files: /linux-6.15/lib/zlib_inflate/Makefile

15d5761a - kbuild: introduce ccflags-remove-y and asflags-remove-y

Tue, 07 Jul 2020 09:21:16 +0000

kbuild: introduce ccflags-remove-y and asflags-remove-yCFLAGS_REMOVE_.o filters out flags when compiling a particularobject, but there is no convenient way to do that for every object ina directory.Add ccflags-remove-y and asflags-remove-y to make it easily.Use ccflags-remove-y to clean up some Makefiles.The add/remove order works as follows: [1] KBUILD_CFLAGS specifies compiler flags used globally [2] ccflags-y adds compiler flags for all objects in the current Makefile [3] ccflags-remove-y removes compiler flags for all objects in the current Makefile (New feature) [4] CFLAGS_ adds compiler flags per file. [5] CFLAGS_REMOVE_ removes compiler flags per file.Having [3] before [4] allows us to remove flags from most (but not all)objects in the current Makefile.For example, kernel/trace/Makefile removes $(CC_FLAGS_FTRACE)from all objects in the directory, then adds it back totrace_selftest_dynamic.o and CFLAGS_trace_kprobe_selftest.oThe same applies to lib/livepatch/Makefile.Please note ccflags-remove-y has no effect to the sub-directories.In contrast, the previous notation got rid of compiler flags also fromall the sub-directories.The following are not affected because they have no sub-directories: arch/arm/boot/compressed/ arch/powerpc/xmon/ arch/sh/ kernel/trace/However, lib/ has several sub-directories.To keep the behavior, I added ccflags-remove-y to all Makefilesin subdirectories of lib/, except the following: lib/vdso/Makefile - Kbuild does not descend into this Makefile lib/raid/test/Makefile - This is not used for the kernel buildI think commit 2464a609ded0 ("ftrace: do not trace library functions")excluded too much. In the next commit, I will remove ccflags-remove-yfrom the sub-directories of lib/.Suggested-by: Sami Tolvanen Signed-off-by: Masahiro Yamada Acked-by: Steven Rostedt (VMware) Acked-by: Michael Ellerman (powerpc)Acked-by: Brendan Higgins (KUnit)Tested-by: Anders Roxell List of files: /linux-6.15/lib/zlib_inflate/Makefile

d4faaecb - [ZLIB]: Fix external builds of zlib_inflate code.

Fri, 12 Oct 2007 05:15:08 +0000

[ZLIB]: Fix external builds of zlib_inflate code.Move zlib_inflate_blob() out into it's own source file,infutil.c, so that things like the powerpc zImage builderin arch/powerpc/boot/Makefile don't end up trying tocompile it.Signed-off-by: David S.

4f3865fb - [PATCH] zlib_inflate: Upgrade library code to a recent version

Thu, 22 Jun 2006 21:47:34 +0000

[PATCH] zlib_inflate: Upgrade library code to a recent versionUpgrade the zlib_inflate implementation in the kernel from a patchedversion 1.1.3/4 to a patched 1.2.3.The code in the kernel is about seven years old and I noticed that theexternal zlib library's inflate performance was significantly faster (~50%)than the code in the kernel on ARM (and faster again on x86_32).For comparison the newer deflate code is 20% slower on ARM and 50% sloweron x86_32 but gives an approx 1% compression ratio improvement. I don'tconsider this to be an improvement for kernel use so have no plans tochange the zlib_deflate code.Various changes have been made to the zlib code in the kernel, the mostsignificant being the extra functions/flush option used by ppp_deflate.This update reimplements the features PPP needs to ensure it continues towork.This code has been tested on ARM under both JFFS2 (with zlib compressionenabled) and ppp_deflate and on x86_32. JFFS2 sees an approx. 10% realworld file read speed improvement.This patch also removes ZLIB_VERSION as it no longer has a correct value.We don't need version checks anyway as the kernel's module handling willtake care of that for us. This removal is also more in keeping with thezlib author's wishes (http://www.zlib.net/zlib_faq.html#faq24) and I'veadded something to the zlib.h header to note its a modified version.Signed-off-by: Richard Purdie Acked-by: Joern Engel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds List of files: /linux-6.15/lib/zlib_inflate/Makefile

1da177e4 - Linux-2.6.12-rc2

Sat, 16 Apr 2005 22:20:36 +0000

Linux-2.6.12-rc2Initial git repository build. I'm not bothering with the full history,even though we have it. We can create a separate "historical" gitarchive of that later if we want to, and in the meantime it's about3.2GB when imported into git - space that would just make the earlygit days unnecessarily complicated, when we don't have a lot of goodinfrastructure for it.Let it rip!
