kernel bbclass: return to original directory in do_deploy

2013-04-23T12:00:52+00:00

* During the base kernel_do_deploy function the directory is changed to DEPLOYDIR in order to do some cleanup and symlinking. However, the directory is not changed back to the original starting directory ${S} at the end. For append functions this means that the starting directory is not ${S} as expected but instead ${DEPLOYDIR}. For functions like the do_deploy_append in recipes-kernel/linux/linux-dtb.inc there is an assumption that you are still in the source directory and not the DEPLOYDIR. Without this change the .dtb files are not copied because the check for the existence of ${DTS_FILE} which is a relative path from the ${S} directory fails. This means that the .dtb files are not copied into the deploy directory and subsequently the deploy/images directory. In the log.do_deploy file you will see lines like: Warning: arch/arm/boot/dts/xxxxx.dts is not available!

kernel.bbclass: remove explicit version.h target

2012-12-13T15:21:44+00:00

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. [YOCTO: #3293] (From OE-Core rev: 1ccc1560114d14f7492c034620ad8d7a8d2ef175) Signed-off-by: Bruce Ashfield Signed-off-by: Richard Purdie

classes: Update to use corrected bb.utils.explode_dep_versions2 API

2012-10-02T10:40:53+00:00

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. This patch also fixes various points in the code to ensure that we do not have any duplicates in things that use explode_dep_versions. A new sanity test to test the contents of the R* variables is also added. [Some changes from Mark Hatle ] (From OE-Core rev: 16a892431d0c0d03f8b561b92909cf2f11af4918) Signed-off-by: Richard Purdie

kernel.bbclass: fix INC directory for SLANG

2012-08-25T13:47:00+00:00

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.

kernel.bbclass: Preserve generated headers only if they exist

kernel.bbclass: Preserve generated headers

2012-08-19T09:45:55+00:00

asm/unistd.h includes asm/unistd_64.h on x86_64 and asm/unistd_32.h on i386 but these files are generated files in 3.4 and when we do 'make clean' they get deleted and it shows up as an error when building external modules. May be its a 3.4 kernel bug may be not but make clean should have left the tree in a shape to build modules but it does not. Probably we should run make modules_prepare after having run make clean.

kernel.bbclass: remove default module_autoload and module_conf values

2012-08-15T13:26:42+00:00

kernel.bbclass is a common class for many different kernel versions, and as such the default module_autoload and module_conf values that it contains are not relevant, or out of date for most builds. Individual kernel recipes or distros can better specify these values to meet their needs.

kernel.bbclass: use ${base_libdir} and ${sysconfdir} instead of /lib and /etc

2012-08-06T14:18:51+00:00

It is considered good practice to use the build system provided variables instead of directly specify hardcoded paths. (From OE-Core rev: c859717f522098e7c68df578d59011f68122dc2c) Signed-off-by: Javier Martinez Canillas Signed-off-by: Richard Purdie

kernel.bbclass: Copy bounds.h only if it exists, needed for 2.6.x.

Linux 2.6.x kernels did not (all) have the bounds.h file, so copy only iff exists. (From OE-Core rev: 02ac0d1b65389e1779d5f95047f761d7a82ef7a4) Signed-off-by: Leon Woestenberg Signed-off-by: Richard Purdie
