2022-11-24kbuild: add ability to make source rpm buildable using kojiIvan Vecera1-0/+10
Changes: - added new target 'srcrpm-pkg' to generate source rpm - added required build tools to spec file - removed locally compiled host tools to force their re-compile Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: Jonathan Toppins <jtoppins@redhat.com> Acked-by: Íñigo Huguet <ihuguet@redhat.com> Tested-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2022-09-29kbuild: hard-code KBUILD_ALLDIRS in scripts/Makefile.packageMasahiro Yamada1-1/+4
My future plan is to list subdirectories in ./Kbuild. When it occurs, $(vmlinux-alldirs) will not contain all subdirectories. Let's hard-code the directory list until I get around to implementing a more sophisticated way for generating a source tarball.

2022-07-27kbuild: rpm-pkg: pass 'linux' to --target option of rpmbuildMasahiro Yamada1-2/+2
Presumably, _target_os is defined even if the --target flag does not specify it, but it is better to make it explicit. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2021-04-25kbuild: deb-pkg: change the source package name to linux-upstreamMasahiro Yamada1-1/+1
Change the source package name from 'linux-$(KERNELRELEASE)' to 'linux-upstream'. Initially, I tried to use 'linux' to be aligned with the Debian kernel package, but Ben suggested 'linux-upstream' so that it is clearly distinguished from distribution packages. [1] The filenames will be changed as follows: [Before] linux-5.12.0-rc3+_5.12.0-rc3+-1.dsc linux-5.12.0-rc3+_5.12.0-rc3+.orig.tar.gz linux-5.12.0-rc3+_5.12.0-rc3+-1.diff.gz [After] linux-upstream_5.12.0-rc3+-1.dsc linux-upstream_5.12.0-rc3+.orig.tar.gz linux-upstream_5.12.0-rc3+-1.diff.gz Commit 3716001bcb7f ("deb-pkg: add source package") introduced KDEB_SOURCENAME. If you are unhappy with the default name, you can override it via KDEB_SOURCENAME.

2020-06-11kbuild: fix broken builds because of GZIP,BZIP2,LZOP variablesDenis Efremov1-3/+3
Redefine GZIP, BZIP2, LZOP variables as KGZIP, KBZIP2, KLZOP resp. GZIP, BZIP2, LZOP env variables are reserved by the tools. The original attempt to redefine them internally doesn't work in makefiles/scripts intercall scenarios, e.g., "make GZIP=gzip bindeb-pkg" and results in broken builds. There can be other broken build commands because of this, so the universal solution is to use non-reserved env variables for the compression tools. Fixes: 8dfb61dcbace ("kbuild: add variables for compression tools") Signed-off-by: Denis Efremov <efremov@linux.com> Tested-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-06-06kbuild: add variables for compression toolsDenis Efremov1-4/+4
Allow user to use alternative implementations of compression tools, such as pigz, pbzip2, pxz. For example, multi-threaded tools to speed up the build: $ make GZIP=pigz BZIP2=pbzip2 Variables _GZIP, _BZIP2, _LZOP are used internally because original env vars are reserved by the tools. The use of GZIP in gzip tool is obsolete since 2015. However, alternative implementations (e.g., pigz) still rely on it. BZIP2, BZIP, LZOP vars are not obsolescent. The credit goes to @grsecurity. As a sidenote, for multi-threaded lzma, xz compression one can use: $ export XZ_OPT="--threads=0" Signed-off-by: Denis Efremov <efremov@linux.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2019-11-11kbuild: Add make dir-pkg build optionMatteo Croce1-1/+2
Add a 'dir-pkg' target which just creates the same directory structures as in tar-pkg, but doesn't package anything. Useful when the user wants to copy the kernel tree on a machine using ssh, rsync or whatever.

2019-08-25kbuild: pkg: rename scripts/package/Makefile to scripts/Makefile.packageMasahiro Yamada1-0/+159
scripts/package/Makefile does not use $(obj) or $(src) at all. It actually generates files and directories in the top of $(objtree). I do not see much sense in descending into scripts/package/. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
