* discover: Separate temporary and permanent device dataJeremy Kerr2013-04-161-7/+11
| | | | | | | | | | | At present, we keep both permanent (eg links/n_links) and temporary (event) data in struct discover_context. This change makes discover_context a temporary structure, just used during actual device discovery. Once discovery is complete, the permanent data (discover_device) is "committed" to the device handler. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* discover: Consolidate user events by device IDJeremy Kerr2013-04-161-3/+3
| | | | | | | | | | Currently, we assume all user events are for a new device. This means that we can never add boot options to an existing device. This change tries to find an existing (matching by ID) device before creating a new one in the user event add path. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* protocol: Separate device add from boot-option add messagesJeremy Kerr2013-04-161-0/+1
| | | | | | | | | | | | | | | | | | | | We want to cater for situations where boot options may be discovered some time after we get notificiation about devices. For instance, discovering boot options from DHCP configuration parameters. In this case, we'll need to notify UIs of boot options appear some time after the device (and/or other boot options on the same device) has appeared. This change adds a new protocol message type, PB_PROTOCOL_ACTION_BOOT_OPTION_ADD. We also rename PB_PROTOCOL_ACTION_ADD to make it clear that it is just for devices. The discover server is updated to send boot option add events at device discover time, but we are now able to decouple this later. We also update the clients to handle the boot option add events separately. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
