* wic: Rename /mic to /wicTom Zanussi2014-08-111-156/+0
| | | | | | | | | | | | | As well as any other stray instances of mic in the codebase that can be removed. We don't really need to carry around legacy naming, and the history is in git.

* wic: Add command to list available source pluginsTom Zanussi2014-07-101-0/+16
| | | | | | | | | | | | | Add a 'wic list source-plugins' command enabling users to get a list of valid partition --sources. This is useful not only for determining sources to use in .wks partition statements, but also for making sense of errors in .wks partition processing.

* wic: check if BBLAYERS is valid before useJoão Henrique Ferreira de Freitas2014-06-061-3/+4
| | | | | | | | | | | | If wic is running as raw mode, it's better to check if BBLAYERS is valid before inspect it. No functional changes.

* wic: add support to look in all layers and get pluginsJoão Henrique Ferreira de Freitas2014-05-211-5/+23
| | | | | | | | | | | | | | | | Plugins are looked in 'scripts/lib/mic/plugins/[type]/' directory on all BBLAYERS variable returned by bitbake environment. If found, it will be load at runtime. The user could create your own plugin and keep it inside its layers. For now the path must be <layer-dir>/scripts/lib/mic/plugins/[type]/. Where 'type' could be 'imager' or 'source'.

* wic: Add SourcePlugin classTom Zanussi2014-02-041-2/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Define the SourcePlugin class, which is the class that should be subclassed to create a 'source' plugin. 'Source' plugins provide a mechanism to customize various aspects of the image generation process in wic, mainly the contents of partitions. The initial version of wic defined a --source param for partitions, which was in the first revision hard-coded to two possible values: rootfs and bootimg. This patch essentially removes the hard-coded --bootimg param and replaces it with a plugin system that maps the value specified as --source to a particular 'source' plugin instead. A 'source' plugin is created as a subclass of SourcePlugin and the plugin file containing it is added to scriptsl/lib/mic/plugins/source/ to make the plugin implementation available to the wic implementation. When the wic implementation needs to invoke a partition-specific implementation, it looks for the plugin that has the same name as the --source param given to that partition. For example, if the partition is set up like this: part /boot --source bootimg-pcbios ... then the methods defined as class members of the plugin having the matching .name class member would be used. To be more concrete, here's the plugin definition that would match a '--source bootimg-pcbios' usage, along with an example method that would be called by the wic implementation when it needed to invoke an implementation-specific partition-preparation function: class BootimgPcbiosPlugin(SourcePlugin): name = 'bootimg-pcbios' @classmethod def do_prepare_partition(self, part, ...) If the subclass itself doesn't implement a function, a 'default' version in a superclass will be located and used, which is why all plugins must be derived from SourcePlugin. This scheme is extensible - adding more hooks is a simple matter of adding more plugin methods to SourcePlugin and derived classes. The code that then needs to call the plugin methods the uses plugin.get_source_plugin_methods() to find the method(s) needed by the call; this is done by filling up a dict with keys containing the methon names of interest - on success, these will be filled in with the actual methods. fPlease see the implementation for examples and details. Note that a source plugin need not restrict itself to methods that apply directly to partitions - methods can also be defined for higher level processing such as at the 'disk' level. The get_default_source_plugin() of DirectImageCreator allows the default source plugin to be retrieved; by default this is set to be the same plugin used for the /boot partition, but that can be overridden by specifying a different --source and therefore different plugin on the 'bootloader' line. This isn't ideal, but it avoids forcing a new high-level object to be defined for that purpose. Note that the '--source rootfs' param remains as its current hard-coded value, which is just the rootfs to be used to populate the partition - by default, that's just the value of the bitbake ROOTFS_DIR variable (or whatever was passed in using the -r param). Note that this also could also be overridden by creating a source plugin using a different name; at this point, unlike with bootimg, there's been no need to do so.

* wic: Add OpenEmbedded-specific implementationTom Zanussi2013-10-011-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Reuses the mic/livecd infrastructure but heavily subclasses and modifies it to adapt to the special needs of building images from existing OpenEmbedded build artifacts. In addition to the OE-specific mic objects and modifications to the underlying infrastructure, this adds a mechanism to allow OE kickstart files to be 'canned' and made available to users via the 'wic list images' command. Two initial OE kickstart files have been added as canned .wks files: directdisk, which implements the same thing as the images created by directdisk.bbclass, and mkefidisk, which can essentially be used as a replacement for mkefidisk.sh. Of course, since creation of these images are now driven by .wks files rather than being hard-coded into class files or scripts, they can be easily modified to generate different variations on those images. They also don't require root priveleges, since they don't use mount to create the images. They don't however write to media like mkefidisk.sh does, but rather create images that can be written onto media.

* wic: Add mic w/pykickstartTom Zanussi2013-10-011-0/+98
This is the starting point for the implemention described in [YOCTO 3847] which came to the conclusion that it would make sense to use kickstart syntax to implement image creation in OpenEmbedded. I subsequently realized that there was an existing tool that already implemented image creation using kickstart syntax, the Tizen/Meego mic tool. As such, it made sense to use that as a starting point - this commit essentially just copies the relevant Python code from the MIC tool to the scripts/lib dir, where it can be accessed by the previously created wic tool. Most of this will be removed or renamed by later commits, since we're initially focusing on partitioning only. Care should be taken so that we can easily add back any additional functionality should we decide later to expand the tool, though (we may also want to contribute our local changes to the mic tool to the Tizen project if it makes sense, and therefore should avoid gratuitous changes to the original code if possible). Added the /mic subdir from Tizen mic repo as a starting point: git clone git://review.tizen.org/tools/mic.git For reference, the top commit: commit 20164175ddc234a17b8a12c33d04b012347b1530 Author: Gui Chen <gui.chen@intel.com> Date: Sun Jun 30 22:32:16 2013 -0400 bump up to 0.19.2 Also added the /plugins subdir, moved to under the /mic subdir (to match the default plugin_dir location in mic.conf.in, which was renamed to yocto-image.conf (moved and renamed by later patches) and put into /scripts.
