* kernel.bbclass: build host programs with native sysrootsWenzong Fan2017-09-211-1/+1
| | | | | | | | | | | | | | | | | | Allow to search header files and libs from native sysroots. For example, an expanded BUILD_CFLAGS includes: '-isystem/builddir/to/linux-yocto/recipe-sysroot-native/usr/include' And an expanded BUILD_LDFLAGS includes: '-L/builddir/to/linux-yocto/recipe-sysroot-native/usr/lib -Wl,-rpath-link,/builddir/to/linux-yocto/recipe-sysroot-native/usr/lib -Wl,-rpath,/builddir/to/linux-yocto/recipe-sysroot-native/usr/lib' (From OE-Core rev: 37f20f2f7bdc8b964736c09371cd8f2342e4d5cb) Signed-off-by: Wenzong Fan <wenzong.fan@windriver.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* kernel: Move Device Tree support to kernel.bbclassOtavio Salvador2017-09-131-0/+3
| | | | | | | | | | | | | | | | The Device Tree is commonly used but it is still kept as a .inc file instead of a proper class. Instead now we move the Device Tree code to a kernel-devicetree class and automatically enable it when the KERNEL_DEVICETREE variable is set. To avoid breakage in existing layers, we kept a linux-dtb.inc file which raises a warning telling the user about the change so in next release this can be removed.

* kernel.bbclass: improve reproducibilityJuro Bystricky2017-08-161-3/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several tweaks to improve reproducibility: 1. If BUILD_REPRODUCIBLE_BINARIES == 1, set KBUILD_BUILD_TIMESTAMP to a reproducible value. This is either a non-zero SOURCE_DATE_EPOCH, or the value obtained from top entry of GIT repo, or (if there is no GIT repo) fallback to REPRODUCIBLE_TIMESTAMP_ROOTFS as the last resort. Also export KCONFIG_NOTIMESTAMP=1. 2. When compressing vmlinux.gz, use gzip "-n" option 3. Kernel and kernel modules contain hard coded paths referencing the host build system. This is usually because the source code contains __FILE__ at some place. This prevents binary reproducibility. However, some compilers allow remapping of the __FILE__ value. If we detect the compiler is capable of doing this, we replace the source path $(S) part of __FILE__ by a string "/kernel-source". For example: ​/data/master/build/tmp/work-shared/qemux86/kernel-source/drivers/media/v4l2-core/videobuf2-core.​c will be replaced by a reproducible value: /kernel-source/drivers/media/v4l2-core/videobuf2-core.c.

* kernel.bbclass: fix KERNEL_IMAGETYPE(S) for Image.gzNicolas Dechesne2017-06-051-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | KERNEL_IMAGETYPES lists all the kernel images that we want to build. in cb17b6c2a7 (kernel.bbclass: support kernel image type of vmlinux.gz), some logic was added to support vmlinux.gz which is not a target built by kernel makefiles (only vmlinux). It is clear that the goal of this logic is only to support vmlinux.gz and not others compressed format (such as Image.gz) which are valid target for kernel makefiles. For Image.gz we should rely on the kernel makefiles and not do the compression in kernel class. This patch updates the logic used to filter out non supported kernel target from KERNEL_IMAGETYPES, and make vmlinux.gz a 'special case', instead of *.gz. If more special cases are needed in the future, we could add them in a similar way. This patch should be a no-op for anyone using vmlinux or vmlinux.gz, and on top of that it is fixing the build for Image.gz which was not working until now.

* kernel, license, sstate, rootfs.py: Remove deploy directory READMEMike Crowe2017-03-011-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | It isn't clear that the README_-_DO_NOT_DELETE_FILES_IN_THIS_DIRECTORY.txt file in the deploy directory warrants the complexity it brings elsewhere. Let's just remove it entirely. In particular, if two do_image_complete tasks run in parallel they risk both trying to put their image into ${DEPLOY_DIR_IMAGE} at the same time. Both will contain a README_-_DO_NOT_DELETE_FILES_IN_THIS_DIRECTORY.txt file. In theory this should be safe because "cp -alf" will just cause one to overwrite the other. Unfortunately, coreutils cp also has a race[1] which means that if one copy creates the file at just the wrong point the other will fail with: cp: cannot create hard link ‘..../tmp-glibc/deploy/images/pantera/README_-_DO_NOT_DELETE_FILES_IN_THIS_D.txt’ to +‘..../tmp-glibc/work/rage_against-oe-linux-gnueabi/my-own-image/1.0-r0/deploy-my-own-image-complete/README_-_DO_NOT_DELETE_FILES_IN_THIS_DIRECTORY.txt’: File exists [1] https://debbugs.gnu.org/cgi/bugreport.cgi?bug=25680 (From OE-Core rev: 71e9e88847d7000781642ea6187ebd8f40dfdcfe) Signed-off-by: Mike Crowe <mac@mcrowe.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

* classes/kernel: fix symlink logic when bundling initramfs imagesAndré Draszik2016-07-011-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If linkpath points to the a file in KERNEL_OUTPUT_DIR, rather than outside, then symlink creation for the bundled initramfs image files fails. This is because in that case $linkpath.initramfs and $realpath.initramfs are in the same directory, KERNEL_OUTPUT_DIR, and hence are the same. Since we just created $realpath.initramfs, creating a symlink with the same name will fail. Given that $linkpath is not necessarily the same as the kernel image type, just removing this symlink creation is not the right thing to do, as in that case kernel_do_deploy() wouldn't find the bundled file. What we really want is a symlink from the name of the initramfs-bundled kernel image type to the real initramfs-bundled kernel image, as that is what is actually used later in do_deploy(). This brings the code path for when $KERNEL_OUTPUT_DIR/$type is a symlink in line with when it is not.

| | | | | | | | | | | | | | | | | | | If multiple kernel image types have been specified, only the very first one would receive a symlink in DEPLOYDIR. The reason is that we're looping over the list of image types and check if a bundled initramfs images exists using a relative path. As part of the loop we're changing the current directory, hence all additional iterations fail to see the files we're looking for, and hence no symlinks are being created. Fix by not changing the directory and adjusting the ln invocation instead.

* Revert "kernel/kernel-arch: Explicitly mapping between i386/x86_64 and x86 ↵Ioan-Adrian Ratiu2016-02-041-12/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | for kernel ARCH" This reverts commit 8d310b24927d0f348fb431895f0583733db2aad0. That commit completely breaks KBUILD_DEFCONFIG because it relies on $ARCH to match between the target OE arch and the kernel subdirectory containing the defconfigs. In the kernel all defconfigs for everything x86-based (including x86_64) is stored in dir arch/x86/configs/ kernel-yocto.bbclass correctly searches for all the defconfigs inside ${S}/arch/${ARCH}/configs/${KBUILD_DEFCONFIG} Commit 8d310b249 makes it search in wrong places and _only_ if you define TARGET_ARCH = "athlon" will it search x86 which is nonsensical. The commit further adds an if clause to hack the mungled kernel arches back to their original values (ugh) in do_shared_workdir which is run after do compile, but of course the build breaks before that in do_kernel_metadata because of the KBUILD_DEFCONFIG mentioned above (so that hack is useless). Please fix that corner case bug in another way which does not completely screw up the kernel arch mapping & defconfig logic. If 64bit configs are generated in the kernel for 32bit machines because the host is asked, then it it a bug in the kernel, it is of no use to hack around it in OE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | kernel ARCH For a bare-bone kernel recipe which specifies 32 bit x86 target, a 64 bit .config will be generated from do_configure task when building 32-bit qemux86, once all of these conditions are true: * arch of host is x86_64 * kernel source tree used in build has commit ffee0de41 which actually chooses i386 or x86_64 defconfig by asking host when ARCH is "x86" (arch/x86/Makefile) * bare-bone kernel recipe inherits directly from kernel without other special treatments. Build will fail because of the mismatched kernel architecture. The patch sets ARCH i386 or x86_64 explicitly to configure task to avoid this host contamination. Kernel artifact is also changed so that it can map i386 and x64 back to arch/x86 when needed.
