|
|
|
|
This thread is responsible for the firmware orchestration strategy.
|
|
Here is how it works:
|
|
- The user creates an update strategy from CLI (or REST API) of 'firmware'
|
|
- This is being handled by the SwUpdateManager class, which
|
|
runs under the main dcmanager thread. The strategy is created and stored
|
|
in the database.
|
|
- The user then applies the strategy from the CLI (or REST API). The
|
|
SwUpdateManager code updates the state of the strategy in the database.
|
|
- The FwUpdateOrchThread wakes up periodically and checks the database for
|
|
a strategy that is in an active state (applying, aborting, etc...). If
|
|
so, it executes the strategy, updating the strategy and steps in the
|
|
database as it goes, with state and progress information.
