kernel-yocto.bbclass: Bug Fix inside do_kernel_checkout()

--047d7b3a7fac0eebee050cb47483 Content-Type: text/plain; charset="UTF-8" After we check the existence of 'machine_branch' with 'git show-ref' the following if statement should change the 'machine_branch' to the default (i.e. master) if the 'git show-ref' has returned an exit code that is not 0, not the other way around.

kernel-yocto: remove GUILT_BASE from terminal exports

2015-01-16T23:08:18+00:00

guilt is no longer used to manage linux-yocto kernel pathes, so we no longer need to export variables that it needed to locate patches in the tree. (From OE-Core rev: eb0209360d14b57fbef6fa20bdd9948e8337f24b) Signed-off-by: Bruce Ashfield Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

kernel-yocto: make sure git tags get dereferenced properly in do_patch()

2014-12-21T12:37:53+00:00

Commit 92c1ece6c347030d48995a36f4c67861356e59d3 causes the test in do_patch() in kernel-yocto.bbclass to fail if ${machine_srcrev} is an annotated tag. The check is meant to ensure that ${machine_srcrev} is an ancestor of HEAD, but if ${machine_srcrev} is a tag, then "$(git rev-parse --verify ${machine_srcrev})" evaluates to the SHA of the tag instead of what it's pointing to. Replacing "$(git rev-parse --verify ${machine_srcrev})" with "$(git rev-parse --verify ${machine_srcrev}~0)" fixed the problem by finding the object pointed to by the tag, and not the tag itself. This also works for commit IDs that are not tags, hence is safe in a scenarios.

kernel-yocto: fix non-git builds

2014-12-21T12:37:53+00:00

The ability to build non-git repositories was broken by two changes: - The existence of an empty 'patches' directory created during the unpack phase. This dir was incorrectly identified as a valid meta directory and broke the build. By ensuring that it is removed before creating the empty repository, it will no longer be found instead of the real meta directory. - The attempt to reset the git repository to a specific SRCREV when no SRCREV was provided. By checking for a SRCREV of 'INVALID', we avoid any processing and failed git operations.

kernel: Rearrange for 1.8

2014-12-21T12:37:53+00:00

In 1.8 we want to streamline the kernel build process. Basically we currently have multiple copies of the kernel source floating around and the copying/compression/decompression is painful. Lets assume we have a kernel source per machine since in most cases this is true (and we have a sysroot per machine anyway). Basically, instead of extracting a source into WORKDIR, then copying to a sysroot, we now set S to point straight at STAGING_DIR_KERNEL. Anything using kernel source can then just point at it and use: do_configure[depends] += "virtual/kernel:do_patch" to depend on the kernel source being present. Note this is different behaviour to DEPENDS += "virtual/kernel" which equates to do_configure[depends] += "virtual/kernel:do_populate_sysroot". Once we do this, we no longer need the copy operation in do_populate_sysroot, in fact there is nothing to do there (yay). The remaining part of the challenge is to kill off the horrible do_install. This patch splits it off to a different class, the idea here is to have a separate recipe which depends on the virtual/kernel:do_patch and just installs and packages the source needed to build modules on target into a specific package. Right now this code is proof of concept. It builds kernels and kernel modules. perf blows up in do_package with issues on finding the kernel version which can probably be fixed by adding back the right bit of do_install, and adding a dependency of do_package[depends] += "virtual/kernel:do_install" to perf. The whole thing needs a good write up, the corner cases testing and probably a good dose of cleanup to the remaining code.

kernel-yocto: fix branch validation for AUTOREV, non machine_meta kernels

2014-10-24T16:36:17+00:00

The simplication of do_validate_branches missed a case where a custom kernel can supply SRCREV="${AUTOREV}", and not use SRCREV_machine at all. In this case, we will incorrectly try and test the tree for a non-existent commit, and break the build. By simplying the condition of the check to look for an empty SRCREV_machine, we can skip manipulating the tree and testing for a SRCREV.

kernel-yocto: replace --is-ancestor with basic git porcelain commands

2014-09-01T13:35:41+00:00

--is-ancestor is a relatively new git option [commit 5907cda1, Aug 30 2012]. To support build machines with older versions of git installed, we can use the basic porcelain commands to acheive the same check. merge-base: "--is-ancestor A B" can be replaced with: if test "$(git rev-parse --verify A)" = "$(git merge-base A B)" (From OE-Core rev: 2ddfffe52720d1df70b04131eac553776da7bc73) Signed-off-by: Bruce Ashfield Signed-off-by: Richard Purdie

kernel-yocto: convert echo statements to bb* equivalents

2014-09-01T13:35:41+00:00

Use the bbinfo, bberror, bbfatal equivalents to the existing echo statements within the kernel-yocto processing. This makes us consistent with the other messages from the build system.
