ccache: Separate out into its own class

2012-05-30T11:04:49+00:00

Currently, ccache is used if it is present. When building from scratch it gives no performance improvement and creates a ton of empty directories even when its not in use. This change moves ccache support to a bbclass file which the user can choose to enable. This should make builds more determinstic and make it easier/clearer to the end user when its being used and when it is not.

kernel-yocto: export GUILT_BASE to devshell

2012-05-11T22:23:31+00:00

One of the patch backends to linux-yocto is guilt, which normally tracks patches under .git. But .git isn't something that can be checked into a SCM and repeated. So it has been moved under meta/patches and committed to the meta branch. If devshell is used, GUILT_BASE isn't set, so patch manipulations will fail. We export GUILT_BASE and point it at the meta directory when devshell is invoked for linux-yocto.

linux-yocto: streamline support for multiple upstream repo types

2012-05-08T15:06:42+00:00

In order to support repositories of various types (with or without meta data, branched, pristine, custom, etc) information about the type of processing that is required was passed to the processing phases via variables. The combination of variables involved in coordinating the processing creates a learning curve and overly complicates recipe extensions. With minor tweaks to the kern-tools, adding flexibility and keying off the existence of the meta branch it is possible to remove all of the variables that were added to support different repository types.

linux-yocto: .diff is a valid patch extension

2012-04-17T22:16:29+00:00

In fixing an existing patch migration bug, the list of valid extensions got out of sync from the core patch class. As a result, valid patches were not being applied to the tree. Updating the tools to migrate .diff files fixes the issue. Also in this fix is the removal of .patch in the find_sccs() routine, since it will never be returned by patch.bbclass when all non-patches are requested, it is simply confusing.

linux-yocto: allow .cfg, .scc, .patch and defconfigs to be processed in order

2012-04-13T21:44:46+00:00

During testing/extension of the linux-yocto-tiny kernel it was found that defconfigs were not always properly applied. This was due to two issues: - not being able to fully control the order of objects applied to the git tree on the SRC_URI - defconfigs triggering --allnoconfig before being applied To fix this, the recipe space code that previously detected and generated automatic features moves back to the kernel tools (where it was before) and is updated to also process .cfg and defconfigs. Moving this back to the tools allow other recipes to automatically benefit from the additional support. The second issue is addressed by allowing configme to take --alldefconfig when a recipe wishes to pass a defconfig and override the default behaviour.

linux-yocto: support externalsrc builds

2012-03-28T09:09:16+00:00

There are a few extra task that modify the source tree that should be removed when externalsrc is inherited by a recipe that uses a linux-yocto tree. Adding those tasks to SRCTREECOVEREDTASKS means that they are skipped and externalsrc works as intended.

linux-yocto: respect FILESPATH directories

2012-03-13T11:45:08+00:00

During the work to enhance the ability to specify out of tree kernel features, an assumption was made about PN being part of a patch path. This assumption is incorrect, since patches can be anywhere in the valid FILESPATH. To make locating the patches in WORKDIR simple, we can just query patch.bbclass and return both the absolute directory of the patch and the subdirectory as it was specified on the src_uri.

linux-yocto: make kernel_checkout reentrant

2012-03-02T15:22:53+00:00

The steps in do_kernel_checkout modify the source tree in WORKDIR. If it is called multiple times, or interrupted, the tree is left in an inconsistent state. This change adds protections around branch names, and around the manipulations of directories to ensure that it is safe to call at any point.

linux-yocto: allow non-branched repositories to check out

2012-02-28T12:27:50+00:00

Not all users of the checkout phase of linux-yocto have all branches present. This is normal, and should be supported. By checking for an empty KBRANCH we can avoid validating a branch that isn't supposed to exist.
