* kernel-devicetree: Cope with non-standard kernel deploy subdirectoryMike Crowe2019-10-231-10/+10
| | | | | | | | | | | | | | | | kernel.bbclass installs non-standard kernels (where KERNEL_PACKAGE_NAME is not "kernel") in a subdirectory of ${DEPLOYDIR}. To achieve this kernel_do_deploy sets the deployDir shell variable to ${DEPLOYDIR} for the standard kernel or ${DEPLOYDIR}/${KERNEL_DEPLOYSUBDIR} for non-standard kernels. kernel-devicetree.bbclass's do_deploy_append ought to do the same and can do so by using the same shell variable.

* kernel-devicetree: Corrected normalize_dtbPaulo Neves2018-07-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | The normalize_dtb function was buggy because it only converted from .dts suffix to .dtb suffix if the user passed a full source path to KERNEL_DEVICETREE containing the /dts/ path. The problem is that if the user did that there would be a warning. On the othet hand if user just set the variable KERNEL_DEVICETREE="file.dts" the bbclass translation to the respective .dtb target did not occur and make would fail saying it has no rule to make target file.dts This patch decouples the logic of having /dts/ in the path from the target translation.

* kernel: Add support for multiple kernel packagesHaris Okanovic2018-01-021-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Move Device Tree support to kernel.bbclassOtavio Salvador2017-09-131-0/+62
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.
