yocto-bsp: qualify user files with machine name

2013-01-25T14:12:36+00:00

The bblayer abstraction makes it where multiple layers can be configured and used at the same time. Some layers make changes to support a specific machine, and should not have any affect when other machines are in use. For linux-yocto, all bsps are created with a user-config.cfg and user-config.cfg and user-patches.scc. This means that those files will be pulled from the first location found, which might correspond to files customized for a different machine. Instead of using the names user-config.cfg and user-patches.scc, I propose a machine specific name be used such as {{=machine}}user-patches.scc and {{=machine}}user-config.cfg. This would necessitate that all references changed to these new names, which would affect the yocto-bsp and yocto-kernel scripts. With this change, it would be possible to have multiple machine BSPs searched at the same time and to select which to build against by using a command like MACHINE=qmeux86 bitbake core-image-sato to override the default. Note many of the standard BSPs do not seem to suffer this problem as they do not use the common files user-config.cfg and user-patches.scc that the yocto-* scripts depend upon. Additions by Tom Zanussi: - renamed user-config.cfg to {{=machine}}-user-config.cfg everywhere - renamed user-patches.scc to {{=machine}}-user-patches.scc everywhere - added the user-config/patches SRC_URI items to the qemu -rt kernel recipes - fixed conflicts due to the new open_user_file() helper function - updated user filename conflicts caused by directory renaming - updated custom kernel files to match Fixes [YOCTO #3731] (From meta-yocto rev: c20bef60aa8d52971fb061d4b8d473ad19c03180) Signed-off-by: Brian A.

yocto-kernel: add support for PRs of the form rN to pr_inc()

2012-12-13T16:54:35+00:00

With the addition of custom kernel support, we also need to handle the normal PR format found in .bb files. (From meta-yocto rev: e17570b6bbd36a731f546f800ef5f271ed5c3697) Signed-off-by: Tom Zanussi Signed-off-by: Richard Purdie

yocto-bsp: remove patch-related SRC_URI processing

2012-12-13T16:54:34+00:00

We no longer have to include patches in the SRC_URI, since things now work using only patch in the .scc file, so remove anything to do with maintaining patches in the SRC_URI and fix up all previous users of that code.

yocto-kernel: handle SRC_URIs in .bb files

2012-12-13T16:54:34+00:00

Previously we assumed we were always dealing with .bbappends. With custom kernels, we now have SRC_URIs in .bb files, so add .bb files to the list of file types we examine and modify.

yocto-kernel: remove assumption that kernel has a version

2012-12-13T16:54:34+00:00

Kernels don't need to have a PREFERRED_VERSION, so remove that assumption from the code that looks for the kernel definition. (From meta-yocto rev: 2ea9d54ac5ebd80b5306851d62411960f3293ede) Signed-off-by: Tom Zanussi Signed-off-by: Richard Purdie

yocto-kernel: don't list comments in config and patch listings

2012-12-13T16:54:34+00:00

After adding comments to the config and patch templates, I noticed they were displayed as items, which they shouldn't be. This prevents them from being displayed. (From meta-yocto rev: 4cd0bde48cd17468923bba80b88d187014cda1a3) Signed-off-by: Tom Zanussi Signed-off-by: Richard Purdie

yocto-kernel: create open_user_file() wrapper function

2012-12-13T16:54:33+00:00

With the addition of custom kernels, we can no longer rely on a hard-coded /files directory for BSPs - we need to be able to find the user_config/patches files in a number of different directories. We now hide the search inside a new open_user_file() function that accomplishes the same thing as before but with a more flexible scope.

yocto-bsp: add 'custom' choice to kernels()

2012-12-13T16:54:32+00:00

Add a synthetic choice for linux-yocto-custom to the list of available kernels. Choosing this will lead the user down the path of options needed to specify a custom kernel. (From meta-yocto rev: 220ad83b5ccc241d7b5b2c3321f2a6a59813e3d6) Signed-off-by: Tom Zanussi Signed-off-by: Richard Purdie

yocto-bsp: Fix git url parsing, allowing for local mirrors

2012-10-24T11:48:24+00:00

The git URLs used in bitbake recipes are not compatible directly with git. In bitbake-speak, all git URLs start with git:// and the protocol is optionally specified in the SRC_URI. Local git mirrors are specified like so: git:///path/to/local/mirror.git;protocol=file The URL that git requires would be: file:///path/to/local/mirror.git Update the yocto-bsp kernel.py to make the necessary adjustment when parsing the SRC_URI to extract the git URL.

yocto-bsp: allow branch display filtering

2012-08-25T13:47:02+00:00

Add a "branches_base" property that can be used to allow only matching branches to be returned from all_branches(). (From meta-yocto rev: c3481e22fc4690ff5e449f9c16c2453fa964205d) Signed-off-by: Tom Zanussi Signed-off-by: Saul Wold Signed-off-by: Richard Purdie
