* kernel.bbclass: allow custom KERNEL_IMAGEDESTIoan-Adrian Ratiu2018-10-251-1/+1
| | | | | | | | | | | Some distros want to install the kernel in a custom location other than /boot and have it properly packaged, so it's useful to use a weaker assignment.

| | | | | | | | | | | | | | | | that." This reverts commit 65cded55fa96b1ba72149a31689c081ac27af7f7. The fitImage deployed here is the one generated in kernel-fitimage.bbclass, whereas the one deployed by kernel-fitimage.bbclass is a raw image, so we need the one deployed here keeping.

* kernel.bbclass: do not deploy fitImage; kernel-fitimage.bbclass does that.Leon Woestenberg2018-09-131-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | kernel-fitimage.bbclass replaces an occurance of "fitImage" in KERNEL_IMAGETYPE_FOR_MAKE by an image type that is buildable for the architecture (such as zImage). The kernel-fitimage.bbclass packs that image as sub-image in a flattened image tree image (fitImage) and deploys this fitImage along with the image tree source file (.its). kernel-fitimage.bbclass does not alter KERNEL_IMAGETYPES, which thus also contains "fitImage", which kernel.bbclass will also deploy redundantly with different naming. The result is a dual deployment with slightly different naming, each with a set of symlinks. The solution chosen is to have fitImage deployment be handled by kernel-fitimage.bbclass, and have kernel.bbclass ignore fitImage types during deployment.

* kernel: specify dependencies for compilation for config tasksBruce Ashfield2018-06-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | With recent kernels (i.e. 4.17+) the configuration phase of the kernel will check for capabilities/options of the compiler for CVE and other mitigation support. For a general kernel, we want to ensure that CC is fully defined when the config targets are invoked (so the proper compiler will be checked). For linux-yocto, we also need to specify the compiler/tools dependencies for the configme task since it executes before configure and hence the main kernel build DEPENDS will not always be in the sysroot before it executes. Without those dependencies the kernel will be incorrectly configured (i.e. bison is missing) or the configuration will fail the mitigation tests.

| | | | | | | | | | | | | | | | | | Commit a1690131691507bbf5853540229b3ad775b836bf removed the ability of recipes to set KERNEL_IMAGETYPE_FOR_MAKE. Fix that by letting recipes continue to set their own KERNEL_IMAGETYPE_FOR_MAKE if they so wish. They may have been doing so for a while, and don't want to have their carefully-selected value trampled on by kernel.bbclass. This may be required if the recipe itself wants to build one type of kernel, but post-process it into a different type, rather like the vmlinux->vmlinux.gz support provided by kernel.bbclass.

* kernel: Add support for multiple kernel packagesHaris Okanovic2018-01-021-41/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some distros may want to provide alternate kernel "flavors" via feeds or within bootable images. For example, readily available builds which provide certain diagnostic features can enable developers and testers to more quickly resolve issues by avoiding lengthy kernel builds. This change allows for building multiple flavors of the kernel and module packages by templatizing kernel package names via a new KERNEL_PACKAGE_NAME variable in kernel.bbclass. It defaults to the old name of "kernel", but can be overridden by certain recipes providing alternate kernel flavors. To maintain compatibility, recipes providing alternate kernel flavors cannot be the "preferred provider" for virtual/kernel. This is because OE puts the preferred provider's build and source at "tmp-glibc/work-shared/$MACHINE/kernel-build-artifacts/" and "tmp-glibc/work-shared/$MACHINE/kernel-source/" instead of "tmp-glibc/work/*/$PN/" like other recipes. Therefore, recipes using the default KERNEL_PACKAGE_NAME="kernel" follows the old semantics -- build in the old location and may be preferred provider -- while recipes using all other KERNEL_PACKAGE_NAME's build from the normal WORKDIR and don't provide "virtual/kernel". Testing: 1. Add `KERNEL_PACKAGE_NAME_pn-linux-yocto-tiny = "tiny-linux"` to local.conf so that linux-yocto-tiny may build alongside the main kernel (linux-yocto). 2. `bitbake linux-yocto linux-yocto-tiny` to build both kernel flavors. 3. Verified image and modules IPKs exist for both: tmp-glibc/deploy/ipk/qemux86/kernel-* for linux-yocto tmp-glibc/deploy/ipk/qemux86/tiny-linux* for linux-yocto-tiny 4. Verified linux-yocto is the "preferred provider", and was built in shared directory: tmp-glibc/work-shared/qemux86/kernel-* 5. Add `CORE_IMAGE_BASE_INSTALL_append_pn-core-image-base = "tiny-linux"` to local.conf to install both kernel flavors in core-image-base. 6. `bitbake core-image-base` to build an image. 7. Verified image contains two bzImage's under /boot/, with "yocto-standard" (linux-yocto recipe) selected to boot via symlink.

* kernel.bbclass: Fix do_sizecheck behaviourMike Crowe2018-01-021-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | During the introduction of support for multiple kernel image types in 849b67b2e4820564b5e5c9bd4bb293c44351c5f3, do_sizecheck was changed to only warn if any kernel was bigger than ${KERNEL_IMAGE_MAXSIZE}. (Well, it tried to warn - it turns out that there's no function called "warn", it should be "bbwarn".) The previous behaviour had been to fail the build if the single kernel image did not fit. It seems possible that people might be generating both compressed and uncompressed kernels and only really care whether the compressed one fits. This means that we shouldn't just always fail if any of the images are too large. So, let's warn (correctly this time) on every image that is too large, but only ultimately fail if no image will fit. The build will also fail if ${KERNEL_IMAGETYPES} is empty, but I hope that no-one needs to do that. While we're here correct a typo in the KERNEL_IMAGE_MAXSIZE validity check.

* 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.
