meta/scripts: Various getVar/getVarFlag expansion parameter fixes

2017-01-09T13:39:11+00:00

There were a few straggling expansion parameter removals left for getVar/getVarFlag where the odd whitespace meant they were missed on previous passes. There were also some plain broken ussages such as: d.getVar('ALTERNATIVE_TARGET', old_name, True) path = d.getVar('PATH', d, True) d.getVar('IMAGE_ROOTFS', 'True') which I've corrected (they happend to work by luck).

meta: remove True option to getVar calls

2016-12-16T10:23:23+00:00

getVar() now defaults to expanding by default, thus remove the True option from getVar() calls with a regex search and replace. Search made with the following regex: getVar ?$( ?[^,()]*), True$ (From OE-Core rev: 7c552996597faaee2fbee185b250c0ee30ea3b5f) Signed-off-by: Joshua Lock Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

kernel-yocto: explicitly trap subcommand errors

2016-12-13T22:55:21+00:00

To trap errors and halt processing, do_kernel_metadata was recently switched to exit on any non zero return code. While the concept is sound, there are subcommands that have legitimate non-zero return codes. Instead of removing set +e, we'll explicitly check the return code of the commands that can error, and throw a bbfatal to alert the user.

kernel-yocto: exit on non-zero return code

2016-12-07T10:46:09+00:00

Historically the processing of kernel meta data contained some commands that exited with a non-zero return code. Special processing was required to properly deal with their exit. That is no longer true, and instead of handling all return codes and doing an explicit 'exit' call, we can remove set -e from the routine and have all errors be trapped and stop processing.

utils.bbclass: add function to check for git config user

2016-10-07T15:43:57+00:00

If attempting to patch a git repo without a proper git config setup, an error will occur saying user.name/user.email are needed by git am/apply. After some code was removed from kernel-yocto, it was simple enough to reproduce this error by creating a kernel patch and using a container to build. This patch abstracts out functionality that existed in buildhistory for use in other classes. It also adds a call to this functionality to the kernel-yocto class.

kernel-yocto: remove do_shared_workdir from SRCTREECOVEREDTASKS

2016-09-14T21:22:12+00:00

Various recipes depend on the kernel's do_shared_workdir task, a quick grep suggests all external kernel modules (via module.bbclass), but also perf, and potentially any additional headers as outlined in linux-libc-headers.inc are affected. Having do_shared_workdir in SRCTREECOVEREDTASKS means this task is removed when externalsrc is enabled, making all those recipes fail as the task they depend on, virtual/kernel:do_shared_workdir, doesn't exist. Remove do_shared_workdir from SRCTREECOVEREDTASKS so that all those recipes work even if externalsrc is activated. According to the comment in here, the reason for do_shared_workdir to be removed as a task is because it modifies the source tree, but that doesn't seem to be case.

kernel-yocto: allow --allnoconfig and --alldefconfig as KCONFIG_MODES

2016-09-08T07:25:11+00:00

Previously merge_config.sh was wrapped by the configme script, configme took the different KCONFIG_MODES as options, and used --allnoconfig or --alldefconfig. With the switch to merge_config.sh no longer being wrapped, the new processing wasn't matching the existing values and only supported allnoconfig or alldefconfig. To avoid breaking existing layers, and also keep any working that have already switched, we can make the case statement match both.

kernel-yocto: restore kernel-meta data detection for SRC_URI elements

2016-09-08T07:25:11+00:00

Before the kernel tools were simplified and streamlined, there was code which not only migrated a patch/cfg/scc to the kernel build tree, it also migrated any subdirectories of those patches. The effect of this data migration was that any other meta data in a patch's directory structure would be available for processing. While we don't want to do this migration anymore, it is possible to check the path of any SRC_URI patches, and if they include a "kernel-meta" subdirectory add it to the search path. This restores the functionality without the old complexity. (From OE-Core rev: 7ef7af5c03bad28faf380986f792f7f3d4d5944d) Signed-off-by: Bruce Ashfield Signed-off-by: Richard Purdie

kernel-yocto: do_kernel_configme: Fix silent sysroot poisoning error

2016-09-05T10:56:01+00:00

do_kernel_configme calls merge_config.sh (installed in the sysroot by the kern-tools-native recipe) which may invoke the compiler to complete the configuration process. Depending on the build (and dependencies), this may error due to sysroot poisoning [1]. The errors are similar to: make[1]: Entering directory '4.1+gitAUTOINC+a7e53ecc27-r0/linux-x64-standard-build' HOSTCC scripts/basic/fixdep work-shared/x64/kernel-source/scripts/basic/fixdep.c:106:23: fatal error: sys/types.h: No such file or directory compilation terminated. make[2]: *** [work-shared/x64/kernel-source/scripts/basic/Makefile:22: scripts/basic/x86_64-nilrt-linux-fixdep] Error 1 Adding $TOOLCHAIN_OPTIONS to $CFLAGS before calling merge_configs.sh fixes the error because $TOOLCHAIN_OPTIONS defines the sysroot and make uses it to correctly compile & fill all missing kernel config options.

kernel-yocto: test for empty artifacts

2016-09-05T10:56:01+00:00

With the updated kernel tools, we generate a list of sccs, patches, configs and BSP definitions as part of the meta data generation. It is valid if there aren't any of these artifacts found (i.e. you are just building a branch and a default config), but invoking the tools with no inputs isn't a good idea. To avoid this issue, we generate a string based on the artifacts and skip calling the tools if there's nothing to do.
