To: u-boot
We switched to Kbuild style makefiles at v2014.01-rc1 release.
With that modification, we can write makefiles simpler.
But it is NOT real Kbuild. We need more progress.
As the next step, this series imports (+ adjusts) build scripts
from Linux Kernel under scripts/ directory.
By applying this series, we can get more advantages:
- short log
- perfect dependency tracking
- preparation to the next step, Kconfig
- other things...
Kbuild without Kconfig
----------------------
First of all, to make things clearer, let me explain
the difference between "Kbuild" and "Kconfig".
They are, I think, sometimes confusing.
Kbuild - build system used for Linux Kernel.
Some features of Kbuild are:
(a) We can describe makefiles simply.
Just add objects to "obj-y" like this:
obj-$(CONFIG_FOO) += foo.o
(b) We can describe directory descending nicely.
Add directories with a slash to "obj-y" like this:
obj-$(CONFIG_BAR) += bar/
(c) Short log like follows:
CC common/foo.o
CC common/bar.o
LD common/built-in.o
(d) Perfect dependency tracking
I think this is the biggest advantage.
To be honest, the dependency tracing of U-Boot build system
was not reliable.
Kconfig - A tool to manage CONFIG macros.
We can handle the dependency among CONFIG macros.
Kconfig allows us to modify CONFIG settings easily
by "make config".
GUI interface are also available by "make menuconfig"
All defined CONFIG macros are stored into ".config" file
I think most of U-boot developers are already familiar with above.
(In most cases, they are Linux Kernel developers too.)
I definitely want to port both of these, but I want to do them separately: Kbuild first.
(If we do Kbuild and Kconfig at the same time, it might be messed up.)
So, I want to do "Kbuild without Kconfig" in this series.
The conventional tool (mkconfig + boards.cfg file)
is used for board configuration.
Prerequisite
------------
You need to apply the followings beforehand to use this series.
[1] sandbox: Use system headers first for sandbox's os.c in a different way
http://patchwork.ozlabs.org/patch/294233/
I confirmed this series can apply on:
Commit 0876703cf + prerequisite[1].
How to Build ?
--------------
We can build the same as before.
Do board configuraton first and then run "make".
$ make omap4_panda_config
Configuring for omap4_panda board...
$ make CROSS_COMPILE=arm-linux-gnueabi-
GEN include/autoconf.mk.dep
GEN include/autoconf.mk
CC lib/asm-offsets.s
GEN include/generated/generic-asm-offsets.h
CC arch/arm/cpu/armv7/omap4/asm-offsets.s
GEN include/generated/asm-offsets.h
HOSTCC scripts/basic/fixdep
...
You will find a difference at a glance: short log.
If you need detail log message, please add "V=1".
(You can also use "V=2")
Please note we can no longer use
$ make omap4_panda CROSS_COMPILE=arm-linux-gnueabi-
to do board configuration and "make" at the same time.
Instead, we can use Kbuild-ish way for that purpose:
$ make omap4_panda_config all CROSS_COMPILE=arm-linux-gnuabi-
This series keeps the other features:
- Support out-of-tree build
You can use "O=<dir_name>" like this
$ mkdir build_dir
$ make omap4_panda_config all O=build_dir CROSS_COMPILE=arm-linux-gnueabi-
- Works with parallel make option
Add "-j" option for this. Compiling will get faster.
- Of cource, SPL, TPL build are supported
(nand_spl also works. But "nand_spl" is obsolete and we should switch to "spl".
Until when should we continue to maintain nand_spl?)
- Breaks no boards (except some boards which are already broken)
I built all target boards to prove correctness of this series
at least for compile test.
My Next Plan
------------
- Import Kconfig
Use "make config", "make menuconfig", "make defconfig", etc. in U-Boot.
- More refactoring
Some parts of makefiles are still dirty.
I want to refactor more makefiles in follow-up patches.
- Use "obj-m" for standalone program?? Loadable module??
I have not deceided about this yet.
Note
----
- I marked dirty parts with "FIX ME".
In some board-specific config.mk files.
# FIX ME
ifneq ($(filter lib lib/lzma lib/zlib, $(obj)),)
ccflags-y := -O2
endif
In the top Makefile
# FIX ME
cpp_flags := $(KBUILD_CPPFLAGS) $(CPPFLAGS) $(UBOOTINCLUDE) $(NOSTDINC_FLAGS)
c_flags := $(KBUILD_CFLAGS) $(cpp_flags)
I will re-write them more nicely after other parts are prepared.
Run Test
--------
- Tested for MPC5121 on an ifm AC14xx board,
Beagle (C4) board and Wand (quad) board by Gerhard Sittig
- Tested for Zynq ZC706 board by me
Run test report for your board is welcome!
Changes for v8:
- Rebase on commit 0876703c.
- Fix a typo in comment in 38/38
Changes for v7:
- Fix a bug in spl build:
In v6, build failed if we try to build another SPL board
without doing "make clobber".
For example,
$ make omap3_beagle_config
$ make CROSS_COMPILE=<your_gcc_prefix>
$ make am335x_evm_config
$ make CROSS_COMPILE=<your_gcc_prefix>
This failed in v6. We needed either "make clobber" or "make mrproper"
before switching to another board.
Now, we can two or more boards continuously.
Changes for v6:
- Rebase on the current u-boot/master
- Linux Kernel 3.13 was released on Jan. 20, so import build scripts
from v3.13 to be breeding edge.
- Minor change in post/lib_powerpc/fpu/Makefile
- Include cmd_files under nand_spl/board/*/*/Makefile
Changes for v5:
- Fix a bug reported by Gerhard Sittig:
"make tools" before running "make" failed at v4.
- Revive "env" target so that we can build only under tools/env/.
- Add a new patch at the tail:
38/38 "tools/env: cross-compile fw_printenv without setting HOSTCC"
- Describe "clobber" target shortly by deleteing "*.imx" and "*.map"
with wildcard matching.
- Rebase on the current u-boot/master
Changes for v4:
- Add a new patch at the tail:
37/37 "kbuild: Do not generate .*.su files at the top directory"
- Change "checkstack" target to Kbuild style
- Move the line where U_BOOT_VERSION is defined
Changes for v3:
- Rebase on the current u-boot/master
- Add a new patch at the tail:
36/36 "board: sandburst: delete FORCEBUILD"
Changes for v2:
- At version 1, nand_spl boards got broken at 12 and fixed at 14.
Fix this problem
- At version 1, sandbox got broken at 17 and fixed at 21.
Fix this problem
- Add a new patch at the tail:
35/35 "Kbuild: chech clean source and generate Makefile for out-of-tree build"
- Rebase on v2014.01-rc2 tag

Ignore generated files by Kbuild such as .*.cmd, *.order, etc.
Besides above,
- Ignore *.s files
We do not need to ignore with file name, asm-offsets.s
- Do not ignore *.rej (for quilt)
- Ignore backup files, \#*#

This commit adds scripts/Makefile.host.tmp which will
be used in the next commit to convert makefiles
under tools/ directory to Kbuild style.
Notice this script, scripts/Makefile.host.tmp
is temporary.
When switching over to real Kbuild,
it will be replaced with scripts/Makefile.host of Linux Kernel.

From: Masahiro Yamada @ 2014-01-29 12:26 UTC (permalink / raw)
To: u-boot
Before this commit, makefiles under tools/ directory
were implemented with their own way.
This commit refactors them by using "hostprogs-y" variable.
Several C sources have been added to wrap other C sources
to simplify Makefile.
For example, tools/crc32.c includes lib/crc32.c

Some Samsung boards have their own tools under board/samsung/<board>/tools/.
This commit refactor more makefiles with "hostprogs-y".
Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
---
Note1:
Samsung boards have tools under board/samsung/<board>/tools/
and have tools/mkexynosspl.c too.
It is inconsistent, so we should choose the appropriate
directory in which Samsung-specific tools are stored.
Note2:
I marded TODO item in board/samsung/origen/Makefile.
Samsung engineers, I hope you will fix the root cause of the warning.
# omit -O2 option to suppress
# warning: dereferencing type-punned pointer will break strict-aliasing rules
#
# TODO:
# Fix the root cause in tools/mkorigenspl.c and delete the following work-around

From: Masahiro Yamada @ 2014-01-29 12:26 UTC (permalink / raw)
To: u-boot
This commit moves suffix rules from config.mk
to scripts/Makefile.build, which will allow us
to switch smoothly to real Kbuild.
Note1:
post/lib_powerpc/fpu/Makefile has
its own rule to compile C sources.
We need to tweak it to keep the same behavior.
Note2:
There are two file2 with the same name:
arch/arm/lib/crt0.S and eamples/api/crt0.S.
To keep the same build behavior,
examples/api/Makefile also has to be treaked.

From: Masahiro Yamada @ 2014-01-29 12:26 UTC (permalink / raw)
To: u-boot
This commit moves some variable definitions from config.mk
to the top Makefile:
- HOSTCC, HOSTCFLAGS, HOSTLDFLAGS
- AS, LD, CC, CPP, etc.
- SHELL (renamed to CONFIG_SHELL)
I'd like to slim down config.mk file
because it is included from all recursive make.
It is redundant to re-define the variables
every time descending into sub directories.
We should rather define them at the top Makefile
and export them.
U-Boot makefiles has been used "SHELL" variable to store shell
chosen for the user, whereas Linux Kernel uses "CONFIG_SHELL".
We should never use "SHELL" variable because it is
a special variable for GNU Make.
Changing SHELL may cause unpredictable side effects
whose root cause is usually difficult to find.
We should use a generic variable name "CONFIG_SHELL".
We should not use the syntax as follows either:
rm -f $(obj)tools/env/{fw_printenv,fw_setenv}
This depends on "bash" although GNU Make generally
invokes "sh" to run the each rule.

O'REILLY GNU Make says like follows about SHELL variable:
By default, /bin/sh is used for the shell.
This shell is controlled by the make variable SHELL
but it is not inherited from the environment.
When make starts, it imports all the variables
from the user?s environment as make variables, except SHELL.
This is because the user?s choice of shell should not cause a
makefile (possibly included in some downloaded software package) to fail.
If a user really wants to change the default shell used by make,
he can set the SHELL variable explicitly in the makefile.
Please refer to the first page of the following PDF file:
http://oreilly.com/catalog/make3/book/ch05.pdf

Changes in v2:
- Do not use bash-dependent clean rules:
For example,
rm -f $(obj)tools/env/{fw_printenv,fw_setenv}
should be converted to
rm -f $(addprefix $(obj)tools/env/, fw_printenv fw_setenv)
- Add more comments in commit log
- Rebase on v2014.01-rc2 tag

This commit adjusts some files to use Kbuild.include.
- Use cc-option defined in Kbuild.include
(Delete cc-option in config.mk)
- Use cc-version defined in
(Delete cc-version in config.mk)
- Move binutils-version and dtc-version to Kbuild.include
by analogy to cc-version
This commit also adds srctree (same as SRCTREE)
to use Kbuild scripts.

Before this commit, most of compiler flags were defined in config.mk.
But it is redundant because config.mk is included from all recursive make.
This commit moves many complier flags to the top Makefile
and export them.
And we use new vaiarables to store them:
KBUILD_CPPFLAGS, KBUILD_CFLAGS, KBUILD_AFLAGS.
This will allow us to switch more smoothly to Kbuild.

This commit changes the working directory
where the build process occurs.
Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.
That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-boot
Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.
And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.
On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.
The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.
Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

This patch seems a big change at a glance.
But the idea is pretty simple.
The major change in the top Makefile is imported
from Linux Kernel from Linux Kernel.
The rest parts are for adjusting prefixes.
- omit $(obj) prefixes for files which are generated in
the top directory
- change $(obj)foo to $(obj)/foo for files which are generated
under sub directories.
- add $(srctree)/ or $(src)/ prefixes when we need to point
to the source files.
- The environmanet BUILD_DIR has been renamed to KBUILD_OUTPUT.
So, this commit modifies MAKEALL too.
FYI:
Basic structure of the top Makefile is as follows:
ifeq ($(KBUILD_SRC),)
ifeq ("$(origin O)", "command line")
KBUILD_OUTPUT := $(O)
endif
ifneq ($(KBUILD_OUTPUT),)
<< define KBUILD_SRC and change directory and restart make >>
skip-makefile := 1
endif
endif
ifeq ($(skip-makefile),)
<<Main part of Makefile>>
endif
Changes in v8: None
Changes in v7: None
Changes in v6:
- Fix doc/DocBook/Makefile
- Rebase on the current u-boot/master
Changes in v5:
- Rebase on the current u-boot/master
Changes in v4:
- Change a little checkstack target:
Use $(src) rather than $(srctree) where Linux Kernel does so.
Changes in v3:
- Rebase on the current u-boot/master
Changes in v2:
- Rebase on v2014.01-rc2 tag
- At version 1, sandbox got broken by this commit
(and fixed again in the lator commit.)
Fix this problem
- Change a little MAKEALL
Do not add "O=<dir>" if objtree is the same as srctree.
This will be helpful at 35/35.

We are going to switch over to Kbuild in upcoming commits.
Each makefile must have non-empty obj- or obj-y
to generate built-in.o on Kbuild.

Some build scripts including scripts/Makefile.build
will be imported from Linux Kernel in the next commit.
We need to adjust them for U-Boot in the following commits.
To make it easier for reviewers to track the modification,
this commit renames scripts/Makefile.build to
scripts/Makefile.build.tmp beforehand.

This commit imports build scripts from Linux Kernel v3.13
as they are.
I know they include some trailing spaces
but I am intentionally keeping them untouched.

+/*
+ * "Optimize" a list of dependencies as spit out by gcc -MD
+ * for the kernel build
+ * ===========================================================================
+ *
+ * Author Kai Germaschewski
+ * Copyright 2002 by Kai Germaschewski <kai.germaschewski@gmx.de>
+ *
+ * This software may be used and distributed according to the terms
+ * of the GNU General Public License, incorporated herein by reference.
+ *
+ *
+ * Introduction:
+ *
+ * gcc produces a very nice and correct list of dependencies which
+ * tells make when to remake a file.
+ *
+ * To use this list as-is however has the drawback that virtually
+ * every file in the kernel includes autoconf.h.
+ *
+ * If the user re-runs make *config, autoconf.h will be
+ * regenerated. make notices that and will rebuild every file which
+ * includes autoconf.h, i.e. basically all files. This is extremely
+ * annoying if the user just changed CONFIG_HIS_DRIVER from n to m.
+ *
+ * So we play the same trick that "mkdep" played before. We replace
+ * the dependency on autoconf.h by a dependency on every config
+ * option which is mentioned in any of the listed prequisites.
+ *
+ * kconfig populates a tree in include/config/ with an empty file
+ * for each config symbol and when the configuration is updated
+ * the files representing changed config options are touched
+ * which then let make pick up the changes and the files that use
+ * the config symbols are rebuilt.
+ *
+ * So if the user changes his CONFIG_HIS_DRIVER option, only the objects
+ * which depend on "include/linux/config/his/driver.h" will be rebuilt,
+ * so most likely only his driver ;-)
+ *
+ * The idea above dates, by the way, back to Michael E Chastain, AFAIK.
+ *
+ * So to get dependencies right, there are two issues:
+ * o if any of the files the compiler read changed, we need to rebuild
+ * o if the command line given to the compile the file changed, we
+ * better rebuild as well.
+ *
+ * The former is handled by using the -MD output, the later by saving
+ * the command line used to compile the old object and comparing it
+ * to the one we would now use.
+ *
+ * Again, also this idea is pretty old and has been discussed on
+ * kbuild-devel a long time ago. I don't have a sensibly working
+ * internet connection right now, so I rather don't mention names
+ * without double checking.
+ *
+ * This code here has been based partially based on mkdep.c, which
+ * says the following about its history:
+ *
+ * Copyright abandoned, Michael Chastain, <mailto:mec@shout.net>.
+ * This is a C version of syncdep.pl by Werner Almesberger.
+ *
+ *
+ * It is invoked as
+ *
+ * fixdep <depfile> <target> <cmdline>
+ *
+ * and will read the dependency file <depfile>
+ *
+ * The transformed dependency snipped is written to stdout.
+ *
+ * It first generates a line
+ *
+ * cmd_<target> = <cmdline>
+ *
+ * and then basically copies the .<target>.d file to stdout, in the
+ * process filtering out the dependency on autoconf.h and adding
+ * dependencies on include/config/my/option.h for every
+ * CONFIG_MY_OPTION encountered in any of the prequisites.
+ *
+ * It will also filter out all the dependencies on *.ver. We need
+ * to make sure that the generated version checksum are globally up
+ * to date before even starting the recursive build, so it's too late
+ * at this point anyway.
+ *
+ * The algorithm to grep for "CONFIG_..." is bit unusual, but should
+ * be fast ;-) We don't even try to really parse the header files, but
+ * merely grep, i.e. if CONFIG_FOO is mentioned in a comment, it will
+ * be picked up as well. It's not a problem with respect to
+ * correctness, since that can only give too many dependencies, thus
+ * we cannot miss a rebuild. Since people tend to not mention totally
+ * unrelated CONFIG_ options all over the place, it's not an
+ * efficiency problem either.
+ *
+ * (Note: it'd be easy to port over the complete mkdep state machine,
+ * but I don't think the added complexity is worth it)
+ */
+/*
+ * Note 2: if somebody writes HELLO_CONFIG_BOOM in a file, it will depend onto
+ * CONFIG_BOOM. This could seem a bug (not too hard to fix), but please do not
+ * fix it! Some UserModeLinux files (look at arch/um/) call CONFIG_BOOM as
+ * UML_CONFIG_BOOM, to avoid conflicts with /usr/include/linux/autoconf.h,
+ * through arch/um/include/uml-config.h; this fixdep "bug" makes sure that
+ * those files will have correct dependencies.

From: Masahiro Yamada @ 2014-01-29 12:26 UTC (permalink / raw)
To: u-boot
Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:
scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
scripts/{Makefile.build,Makefile.host,Makefile.lib}.
This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj
We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.
Additionally, we need to fix compiler flags which are
locally added or removed.
In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.
Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
Tested-by: Gerhard Sittig <gsi@denx.de>
---
Please note that we are not allowed to change CFLAGS locally.
See the following snippet from scripts/Makefile.build
# If the save-* variables changed error out
ifeq ($(KBUILD_NOPEDANTIC),)
ifneq ("$(save-cflags)","$(CFLAGS)")
$(error CFLAGS was changed in "$(kbuild-file)". Fix it to use ccflags-y)
endif
endif
If you are not familiar with Kbuild style makefiles,
I recommend you to read the document in Linux Kernel:
Documentation/kbuild/makefiles.txt
Changes in v8: None
Changes in v7:
- Rebuild SPL liner script everytime.
This fixes a bug in spl build:
In v6, build failed if we try to build another SPL board
without "make clobber".
For example,
$ make omap3_beagle_config
$ make CROSS_COMPILE=<your_gcc_prefix>
$ make am335x_evm_config
$ make CROSS_COMPILE=<your_gcc_prefix>
This failed in v6. We needed either "make clobber" or "make mrproper"
before switching to another board.
Now, we can build two or more boards continuously.
Changes in v6:
- Fix doc/DocBook/Makefile
- Minor change in post/lib_powerpc/fpu/Makefile
- Include cmd_files in nand_spl/board/*/*/Makefile
and examples/standalone/Makefile
Changes in v5:
- Rebase on the current u-boot/master
Changes in v4: None
Changes in v3:
- Use "all:" instead of "__build:" in nand_spl Makefiles
Changes in v2: None

We can get Kbuild-ish log style like this:
GEN include/autoconf.mk
GEN include/autoconf.mk.dep
We do not need XECHO any more.
And also change checkstack target like Linux Kernel.

This commit changes the location of include directives
of board configuration files.
The purpose of this change is:
- Slim down $(TOPDIR)/config.mk
- Prevent $(TOPDIR)/Makefile from including the same
configuration file twice
- Do not include include/config.mk multiple times
because ARCH, CPU, BOARD, VENDOR, SOC are exported
Before this commit:
- include/autoconf.mk was included from $(TOPDIR)/Makefile
and $(TOPDIR)/config.mk
(This means $(TOPDIR)/Makefile included include/autoconf.mk twice)
- include/{spl,tpl}-autoconf.mk was included from $(TOPDIR)/config.mk
- include/config.mk was included from $(TOPDIR)/Makefile
and $(TOPDIR)/config.mk
(This means $(TOPDIR)/Makefile included include/config.mk twice)
After this commit:
- include/autoconf.mk is included from $(TOPDIR)/Makefile
and $(TOPDIR)/scripts/Makefile.build
- include/{spl,tpl}-autoconf.mk is included from $(TOPDIR)/spl/Makefile
and $(TOPDIR)/scripts/Makefile.build
- include/config.mk is included from $(TOPDIR)/config.mk and
$(TOPDIR)/spl/Makefile

Before this commit, {spl,tpl}-autoconf.mk was always generated
at the top Makefile even if SPL(TPL) build was not selected.
This commit moves the build rule of {spl,tpl}-autoconf.mk
from the top Makefile to spl/Makefile.
It prevents unnecessary {spl,tpl}-autoconf.mk from being
generated.

Before this commit, "make tidy" did
"make clean" + delete "*.depend*" files.
But, we do not have "*.depend*" files any more,
which means "make tidy" is the same as "make clean".
This commit removes the redandant target "tidy".

This commit changes the top Makefile to handle various targets
nicely.
Make targets are divided into four categories:
- mixed-targets
We can call a configuration target and build targets
at one command line like follows:
$ make <board_name>_config u-boot
They are handled one by one.
- config targets
<board_name>_config
- no-dot-config-targets
Targets we can run without board configuration such as
clean, mrproper, distclean, TAGS, %docs, etc.
- build targets
The other target which need board configuration.

This commit refactors rules of directory descending
and defines u-boot-dirs and u-boot-all-dirs.
(We will need u-boot-all-dirs when using
scripts/Makefile.clean)
Additionally, rename LIBS-y to libs-y.

$(MTD_VERSION) is used in tools/env/Makefile
If you specify a variable at a command line like:
$ make MTD_VERSION=old env
or specify it thru an envrionment variable like:
$ export MTD_VERSION=old
$ make env
it is inherited to the sub-make too.
We do not need to pass it from the top Makefile explicitely.

This commit refactors cleaning targets such as
clean, clobber, mrpropper, distclean
with scripts/Makefile.clean.
By using scripts/Makefile.clean, we can recursively descend
into subdirectories and delete generated files there.
We do not need add a big list of generated files
to the "clean" target.

We can delete ugly stuff like follows:
clean:

By the way, I am keeping "make clobber" for now.
Do we need "make clobber"?
If we like 3-level cleaning targets, clean, mrproper, distclean,
like Linux Kernel, we can squash "clobber" to "clean".

This commit fixes two problems:
[1] We could not do board configuration and "make all"
in one command line.
For example, the following did not work as we expect:
$ make sandbox_config all
Configuring for sandbox board...
make: Nothing to be done for `all'.
[2] mixed-target build did not work with -j option
For example, the following did not work:
$ make -j8 sandbox_config u-boot
Makefile:481: *** "System not configured - see README". Stop.
make: *** [u-boot] Error 2
make: *** Waiting for unfinished jobs....
Configuring for sandbox board...
Going forward, we can do
$ make -j8 sandbox_config all
This is the same as
$ make sandbox_config
$ make -j8

We had switched to Kbuild, so we do not need to
delete sandburst board files at every build.
U-Boot conventional build system did not check the
update of command line option, -DBUILDUSER.
Kbuild can handle it nicely and re-builds object files
when command line options are changed.
(The file ".*.cmd" stores the information how the file
was generated at the previous build.)

Without this workaround, you will see a lot of ".*.su" files
at the top directory after building with a compiler
which supports "-fstack-usage" option.

fw_printenv is a program which mostly runs on the target Linux.
Before switching to Kbuild, we needed to set HOSTCC at the
command line like this:
make HOSTCC=<your CC cross-compiler> env
Going forward we can cross compile it by specifying CROSS_COMPILE:
make CROSS_COMPILE=<your cross-compiler prefix> env
This looks more natural.

compile test for this setup and a few others run successfully on OS X
Lion as build-host.
Runtime test on at least one avr32 and one at91 board will follow this
weekend.
I saw a few times full compiler output instead of the shortened 'CC
...'. Especially generating the linker script, reformatting binaries
with objcopy and doing the final linkage of u-boot ELF. Maybe you want
to sort that out?
Sorry if that was discussed before, haven't followed the whole discussion.
Nevertheless, many thanks for your great work!
Best regards

Hello Tom,
Now, this kbuild series cleanly applies on the current u-boot/master.
(commit 07e2822d158940a0e8ba45b6ab0344ffa1011a07)
What's your plan about this series?
Are we ready to switch to Kbuild, or need more review?

Everything looks good except for me I see a significant performance
regression on this. I suspect it is just that -j is not working
properly on make.
HEAD is now at 05ed548 dts: re-write dts/Makefile more simply with Kbuild
(=05ed54) u> time crosfw -b snow -w
Configuring for snow board...
real 0m27.723s
user 0m47.940s
sys 0m10.320s
(=05ed54) u> co upstream/master
Note: checking out 'upstream/master'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:
git checkout -b new_branch_name
HEAD is now at 07e2822... board: nios2: Check if flash is configured
before calling early_flash_cmd_reset()
(<detached:remotes/upstream/master=07e282) u> time crosfw -b snow -w
Configuring for snow board...
real 0m8.818s
user 0m36.290s
sys 0m5.040s
So it is 3x slower with Kbuild for some reason. Do you see this? For

Lets get the performance problem Simon found figured out, but then
otherwise, yes, I think we're about ready to merge.

This is my analysis of Kbuild performance.
[1] -j option is working
What I must say first is -j option is working correctly with Kbuild.
You can double-check by following the steps below.
Apply Kbuild series v8 on
commit 07e2822d158940a0e8ba45b6ab0344ffa1011a07.
First, build without -j option.
$ make mrproper
$ time make CROSS_COMPILE=arm-linux-gnueabi- snow_config all
Configuring for snow board...
GEN include/autoconf.mk.dep
[snip]
real 1m15.089s
user 0m44.092s
sys 0m32.513s
Next, build with -j8 option.
(Run "make mrproper" every time because we want to be sure
that there are no generated files before build.)
$ make mrproper
$ time make -j8 CROSS_COMPILE=arm-linux-gnueabi- snow_config all
[snip]
real 0m17.223s
user 0m50.010s
sys 0m29.038s
It is much faster with -j8 option than without -j option.
(4.3 times faster on my box.)
You will easily notice another proof that -j option is working.
If you do not add -j option, the shorten log will be displayed
in the alphabetical order of output file name:
LD arch/arm/cpu/built-in.o
CC arch/arm/cpu/armv7/cache_v7.o
CC arch/arm/cpu/armv7/cpu.o
CC arch/arm/cpu/armv7/syslib.o
CC arch/arm/cpu/armv7/s5p-common/cpu_info.o
CC arch/arm/cpu/armv7/s5p-common/timer.o
CC arch/arm/cpu/armv7/s5p-common/sromc.o
CC arch/arm/cpu/armv7/s5p-common/pwm.o
LD arch/arm/cpu/armv7/s5p-common/built-in.o
LD arch/arm/cpu/armv7/built-in.o
AS arch/arm/cpu/armv7/start.o
CC arch/arm/cpu/armv7/exynos/clock.o
CC arch/arm/cpu/armv7/exynos/power.o
On the other hand, if you add -j option, the log will be shown
in a different order:
LD arch/arm/cpu/built-in.o
CC arch/arm/cpu/armv7/cache_v7.o
CC arch/arm/cpu/armv7/exynos/clock.o
CC disk/part.o
AS arch/arm/lib/crt0.o
CC board/samsung/common/board.o
CC board/samsung/smdk5250/smdk5250_spl.o
CC common/main.o
LD drivers/block/built-in.o
LD board/samsung/common/built-in.o
CC arch/arm/cpu/armv7/cpu.o
AS arch/arm/lib/relocate.o
CC disk/part_dos.o
CC arch/arm/cpu/armv7/exynos/power.o
[2] Is Kbuild slower than the old U-Boot build system?
Yes, Kbuild is definitely slower.
(But, as far as I tested, I don't think it is 3 times slower.)
Let's compare the build time with the conventional build system.
Checkout master branch.
(commit 07e2822d158940a0e8ba45b6ab0344ffa1011a07)
$ make mrproper
$ time make CROSS_COMPILE=arm-linux-gnueabi- snow
real 0m45.612s
user 0m28.367s
sys 0m18.969s
So, Kbuild(=real 1m15.089s) is 1.6 times slower
than the old U-Boot build system.
[3] Why is Kbuild slower?
One reason is "fixdep".
The helper program, fixdep, parses the source file
and all headers included from it to search all CONFIG
macro used there. This is a rather heavy task.
If you don't know the reason why "fixdep" is necessary,
please read the comment block of scripts/basic/fixdep.c
It is true that fixdep is meaningless for now,
but it will be a great help when switching to Kconfig.
We will get more return than we pay.
(And Kconfig series is almost ready.
I will test more and post version 1 within a couple of weeks.)
Let' check how big the impact of fixdep is.
I prepared a patch for you to disable fixdep:
http://patchwork.ozlabs.org/patch/316057/
Apply it on
commit 07e2822d158940a0e8ba45b6ab0344ffa1011a07 + Kbuild v8
And then, build.
$ make mrproper
$ time make CROSS_COMPILE=arm-linux-gnueabi- snow_config all
real 1m2.436s
user 0m38.281s
sys 0m25.871s
It is faster by 1.2 times faster without fixdep than it is with fixdep.
Another big factor is "arg-check".
This excellent routine is defined in scripts/Kbuild.include.
The dependency tracking of U-Boot old build system is
absolutely unreliable.
It compares the timestamp between object files and source files,
but never checks the arguments given to the compiler.
Kbuild checks both of them to precisely detect which objects must
be re-built.
To see how heavy "arg-check" task is,
build with KBUILD_NOCMDDEP=1 option to disable "arg-check".
$ make mrproper
$ time make CROSS_COMPILE=arm-linux-gnueabi- KBUILD_NOCMDDEP=1 snow_config all
real 0m41.882s
user 0m28.432s
sys 0m14.971s
See?
It is as fast as the old U-boot system(=0m45.612) .
Conclusion:
The main reasons of the slow down with Kbuild are "fixdep" and "arg-check".
Both of them are really important features for Kbuild and Kconfig.
- "fixdep" is mandatory for our better life with Kconfig.
- "arg-check" is for perfect dependency tracking.

Tom, are you satisfied with my analisys?
But, please hold merging Kbuild series.
I will post version 9 with a little minor update.

I am, yes. I guess if we're unhappy with the times, if we can improve
them we can push that back to the kernel and that's a good thing.

Thanks for your detailed analysis of this. The slower build time is
unfortunate but I think it is worth it. The fixdep thing is similar to
the penalty from the autoconf series I did a while ago. Maybe the
scripts can be sped up, I'm not sure.

Well IMO the sooner this is merged the better so that the Makefiles
become stable again.

I'm not sure whether to start a new thread or not, but here in one
observations which might be useful.
With current master, a 'null' build (with nothing changed) takes about
5s for me.
time CROSS_COMPILE=/opt/linaro/gcc-linaro-arm-linux-gnueabihf-4.8-2013.08_linux/bin/arm
-linux-gnueabihf- ARCH=arm make -j1
real 0m4.978s
user 0m1.144s
sys 0m0.360s
With the kbuild series, it takes a lot longer:
real 0m46.600s
user 0m17.628s
sys 0m8.664s
There seem to be noticeable pauses between things happening. I'm not
quite sure how to dig into it more. Is it possible that cc-option is
no-longer caching the various compiler options?
Regards,
Simon

Thanks for your feedback.
Hmm, Kbuild is 9 times slower on your computer.
This is a big difference. (It was about 1.6 x slower on my box.)
I don't know where such a difference came from.

I guess it's possible.
Is sandbox build slow as well?
Sandbox has no cc-option.
If cc-option is the cause of pauses, sandbox build
should be faster.
Anyway, evaluating cc-option multiple times isn't nice
and its optimization is on my TODO list.
Historically, U-Boot has included all
config.mk (arch/*/config.mk and board/*/config.mk)
every time descending into subdirectories.
That means cc-options are evaluated over and over again.
Caching cc-option is one of work arounds, but we should not
revive it.
What we should do is to include arch/*/config.mk and board/*/config.mk
only once at the top Makefile and export options.

Agreed. Weather ate most of last week for me when I had hoped to clear
out some things and then grab this series. Back at it all now..

Hello Tom,
I notice Kbuild fails to build venice2 board
because commit 52ef43b0529 added an empty Makefile,
arch/arm/cpu/armv7/tegra124/Makefile.
What shall we do with this?
Do you need v10 or shall I fix it in a follow-up patch?

It's interesting and I want to know how fast.

Can we move this up on the TODO list please? Some quick testing

I will deal with this task as the first priority.

Thanks! This is something we can push up to the kernel community too
and I hope they'll (a) agree with and (b) be happy about.
