wic: Honor --size for --source partititions

2014-02-09T09:40:01+00:00

Instead of simply creating partitions large enough to contain the contents of a --source partition (and adding a pre-specified amount of padding), use the --size used in the partition .wks statement. If --size isn't used, or is smaller than the actual --source size, retain the current behavior.

wic: Hook up --debug option

2014-02-04T12:57:36+00:00

Hook up the existing --debug option to toggle the wic debug loglevel, which is indispensible when things go wrong, and make it easy to use from the command-line. (From OE-Core rev: a5ece6f37656fa56b97fd8faf52917345238d015) Signed-off-by: Tom Zanussi Signed-off-by: Richard Purdie

wic: Hook up BootimgEFIPlugin and BootimgPcbiosPlugin plugins

2014-02-04T12:57:36+00:00

Remove all the Wic_PartData and DirectImageCreator code now implemented by the BootimgEFIPlugin and BootimgPcbiosPlugin plugins, as well as all the special-cased boot_type code, significantly cleaning up the code. Replace the calling code with general-purpose plugin invocations, in essence calling the appropriate implementations at run-time based on the --source value in effect. Change the directdisk.wks and mkefidisk.wks scripts to make use of the new plugins.

wic: Add BootimgEFIPlugin and BootimgPcbiosPlugin

2014-02-04T12:57:35+00:00

Implement the BootimgPcbiosPlugin and BootimgEFIPlugin SourcePlugin classes. The configure/prepare_partition() methods are implemented using code derived from similar code in the Wic_PartData class. These classes have the corresponding names 'bootimg-pcbios' and 'bootimg-efi', which are the names that should be used in the --source parameters of the .wks partition commands.

wic: Add SourcePlugin class

2014-02-04T12:57:35+00:00

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 wic-specific bootloader subclass

2014-02-04T12:57:35+00:00

Add a new wic-specific bootloader subclass so we can add a --source param to hang non-partition plugin off of. By default, the bootloader gets the /boot partition source plugin, but this can be overridden by the --source bootloader param if needed.
