* kernel.bbclass: Stop bundle_initramfs thwarting sstate cache and fix raceMike Crowe2013-11-241-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | The new do_bundle_initramfs task introduced in 609d5a9ab9e58bb1c2bcc2145399fbc8b701b85a defeats using the sstate cache. The kernel is resurrected from the sstate cache but ends up being built again since do_bundle_initramfs depends on do_compile. The task is no longer nostamp to avoid causing unnecessary rebuilds. The sstate checksum stamps should know when to rebuild. The task now runs before do_deploy and part of the work has been moved to do_deploy where it now writes to ${DEPLOYDIR} rather than ${DEPLOY_DIR_IMAGE} so that the files end up in sstate. The task can also race against do_install since both call into the kernel build system. This is fixed by making do_bundle_initramfs run after do_install (which therefore also fixes the problem that 3baa63b4d588c3262254528b406ede265dd117bf was addressing.)

| | | | | | | | | | | | | | | If kernel_do_compile() encounters a .lzma image for the initramfs, it attempts to decompress it using the little-known "lzmash" utility. This may not be present, which will cause the build to fail. Fortunately, it appears that the more mainstream "lzma" tool is compatible so we can use that one instead.

The build continues, while the test fails and no copy is made into the sysroot. Eventually tasks like build_hdimg will fail with the missing kernel with the root cause being less than obvious.

| | | | | | | | | | | | | | | | | commit df564c4 [kernel: Use hardlinks for do_populate_sysroot for speed] does indeed speed up the build, but it also means that the KERNEL_OUPUT and KERNEL_IMAGETYPE may be hardlinks. If they are hardlinks, install complains that they are actually the same file and stops the build. We can easily test and avoid the copy if the file is already in place.

* kernel: Use hardlinks for do_populate_sysroot for speedRichard Purdie2013-11-121-2/+2
| | | | | | | | | | | | | | | | The kernel tree is large and doesn't need to be copied. Override the default sysroot handling function to use a hardlink copying function in python. This commit also drops the copying of the /lib directory which just contains the kernel modules. We never use those in the sysroot so there is little point in carrying those around. For linux-yocto this takes the do_populate_sysroot time 24s -> 14s. (From OE-Core rev: 13259459e200a237ca486cbe1123a0b0a4d1eebf) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* kernel: Use hardlinks during do_install for speedRichard Purdie2013-11-121-9/+9
| | | | | | | | | | | | | | | | | | | | Whilst the comment says we can't do this, its incorrect, install operates on WORKDIR and its hard for different parts of WORKDIR to be on different filesystems. Hardlinking instead of copying is therefore a nice performance gain. Also, completely skip the Documentation directory (adding a dummy Makefile to keep make happy) and tweak the other cp commands to link since if we don't we'd get "this is the same file" type errors from cp for some kernel versions. For do_install on linux-yocto, this takes it from 227s -> 84s.

* kernel.bbclass: Delay rm_work to run after do_bundle_initramfsXufeng Zhang2013-11-051-1/+1
| | | | | | | | | | | | | | | | | | | | Since kernel will build twice when we are trying to bundle kernel and initramfs together after commit 609d5a9ab("kernel.bbclass, image.bbclass: Implement kernel INITRAMFS dependency and bundling"), thus, the second building for kernel would fail if rm_work is done previously. To fix this problem, we need to make do_bundle_initramfs task run before do_rm_work task.

* kernel: restore scripts in the sysrootBruce Ashfield2013-10-141-0/+11
| | | | | | | | | | | | | | | | When building against the sysroot, out of tree modules can require modpost and other utilities normally found in the kernel's scripts directory. For the kernel source in the staging dir, these scripts have been removed to avoid mixing archiectures when packaging kernel-dev (among other things). Rather than further complicate the kernel's install rule, or its packaging, we can restore the scripts by building them in the kernel staging directory after the sstate is installed, making them available to packages that need them.

* kernel.bbclass: Allow INITRAMFS_TASK to trigger copy initramfs codeJason Wessel2013-09-301-0/+8
| | | | | | | | | | | | | | | | | | | | Activating the INITRAMFS_TASK can cause circular dependencies, but that is up to the end user to resolve in recipes. The INITRAMFS_TASK should also trigger immediate linking of the cpio task in the first compile pass. This was a subtle regression introduced by: 609d5a9ab (kernel.bbclass, image.bbclass: Implement kernel INITRAMFS dependency and bundling). This patch restores the previous behavior and only affects the INITRAMFS_TASK which is not set by any of the default build profiles in oe-core.

* kernel.bbclass, image.bbclass: Implement kernel INITRAMFS dependency and ↵Jason Wessel2013-09-061-12/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bundling This patch aims to fix the following two cases for the INITRAMFS generation. 1) Allow an image recipe to specify a paired INITRAMFS recipe such as core-image-minimal-initramfs. This allows building a base image which always generates the needed initramfs image in one step 2) Allow building a single binary which contains a kernel and the initramfs. A key requirement of the initramfs is to be able to add kernel modules. The current implementation of the INITRAMFS_IMAGE variable has a circular dependency when using kernel modules in the initramfs image.bb file that is caused by kernel.bbclass trying to build the initramfs before the kernel's do_install rule. The solution for this problem is to have the kernel's do_bundle_initramfs_image task depend on the do_rootfs from the INITRAMFS_IMAGE and not some intermediate point. The image.bbclass will also sets up dependencies to make the initramfs creation task run last. The code to bundle the kernel and initramfs together has been added. At a high level, all it is doing is invoking a second compilation of the kernel but changing the value of CONFIG_INITRAMFS_SOURCE to point to the generated initramfs from the image recipe.

For example: KERNEL_IMAGE_STRIP_EXTRA_SECTIONS = ".comment .unwanted" The kernel output is stripped in place. Since the toolchain does not give indication when the specified sections are absent, we read the sections first and make this report by issuing a warning to the developer. The toolchain by default strips the image with the -s option (even when -s is not specified): -s --strip-all Remove all symbol and relocation information For example, these sections are always removed: .debug_aranges .debug_info .debug_abbrev .debug_line .debug_frame .debug_str .debug_loc .debug_ranges .symtab .strtab In addition to these, the sections listed in KERNEL_IMAGE_STRIP_EXTRA_SECTIONS will also be removed. Only stripping of vmlinux (elf) is supported at this time. A warning will be given if the image type is not vmlinux. Stripping the image could also be done in the kernel, but that would only work for linux-yocto based kernels, so it's not the route we decided to go.

| | | | | | | | | | | | | | | | | | | | | | | | | | | do_sizecheck has a few issues especially with vmlinux image type. It breaks because KERNEL_OUTPUT is a path relative to ${B}. When do_sizecheck runs it does not find the file (because the working directory is elsewhere) and does not fail. Also, the image file referenced by KERNEL_OUTPUT may be a link. Finally, when do_sizecheck deletes the oversized kernel image it leaves the previously run do_compile task with inaccurate status. So, do the following: - specify that the working directory should be ${B} - use ls -L to reference to the real file, and ensure that the link file is created - keep the oversized image file so the status of do_compile is valid [YOCTO #3514] (From OE-Core rev: f0b19ddce3c92c5d06976cf73d4c4c480e053dff) Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Michel Thebeau <michel.thebeau@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

* kernel: avoid copying unnecessary files during do_installMark Asselstine2013-02-011-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | kernel_do_install() populates $kerneldir with files needed to build external modules. To accomplish this there are several copy commands to get source from the kernel source tree and build trees after which a 'clean' is performed. Since we are copying from the build tree we get about 1G of .o and .cmd files copied over only to have them removed when we clean. This adds additional IO overhead as well as overhead caused by pseudo. By avoiding copying these files in the first place we get multiple gains: * avoid initial copy * avoid file deletes during clean * reduce pseudo overhead Additionally we are making use of cpio vs cp which tends to be significantly faster at performing copies. With these changes I observe a 15-30% decrease in the time to complete the do_install() operation on the kernel.

* kernel.bbclass: remove explicit version.h targetBruce Ashfield2012-10-191-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The compilation routine for the kernel has an explicit call to build version.h, which works fine for most kernels, but the location of it has recently changes. commit d183e6f5 [UAPI: Move linux/version.h] commit 10b63956 [UAPI: Plumb the UAPI Kbuilds into the user header installation and checking] moves the file to include/generated/linux/version.h and then to include/generated/uapi/linux/version.h. As a result kernel builds of 3.7 or bisection builds of intermediate kernel commits will fail with: make[2]: *** No rule to make target `include/linux/version.h'. Stop. Making the explicit version.h build conditional on the version, or via a file test would fix the problem, but it introduces some complexity to the build. Even without an explicit call to build version.h, it is always produced by the kernel build, so it can simply be removed. This extra make line was originally so that the kernel version could be determined, so that then different instructions could be executed depending on whether it was a 2.4 or 2.6 kernel. Since we no longer support 2.4, this code is no longer needed.

Also, it causes a problem when building a read-only rootfs since update-modules itself refuses to configure offline. Allow DISTROs to circumvent this whole thing by declaring (via DISTRO_FEATURES) that they don't wish to use update-modules. This is backfilled for existing distributions and will have to be marked as CONSIDERED by those who actually don't want it.

| | | | | | | | | | | | | | | | | The bb.utils.explode_dep_versions function has issues where dependency information can be lost. The API doesn't support maintaining the correct information so this changes to use a new function which correctly handles the data.

A new sanity test to test the contents of the R* variables is also added.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | In the kernel's tools/perf/Makefile CFLAGS was previously hard coded to contain "-I/usr/include/slang" to work with hosts that have "/usr/include/slang/slang.h" as well as hosts that have "/usr/include/slang.h". This path can cause compile warnings like: cc1: warning: '/usr/include/slang' doesn't exists. or cc1: warning: include location "/usr/include/slang" is unsafe for cross-compilation [-Wpoison-system-directories] Then in some cases warnings become errors if WERROR is enabled hence build errors. In coordination with a kernel fix, we can fix this error for all kernels by modifying the perf Makefile within the staged kernel source.
