dbus-top: initial commits
This commit covers the basic functionalities of the dbus-top tool.
The UI is divided into 3 windows as follows:
+--------------------------+ Window list
| Window A | A: Summary statistics
+------------+-------------+ B: Sensor list or detail
| Window B | Window C | C: Detailed statistics
+------------+-------------+
To navigate the UI:
* Use tab to navigate each window
When a window is highlighted:
In Window B:
* Press esc key 3 times to leave the current sensor selection
In Window C:
* Press [Enter] to show/hide pop-up menu for column selectio
* Press [Left] to move highlight cursor to the left
* Press [Right] to move highlight cursor to the right
* Press [A] to sort by the highlighted column in ascending order
* Press [D] to sort by the highlighted column in descending order
To add recipe to Yocto and build the recipe:
1) Copy and paste the content of the .bb file into a folder that can be
detected by bitbake, such as meta-phosphor/recipes-phosphor/ipmi.
2) run "devtool modify -n dbus-top (path_to_openbmc_tools)/dbus-top/".
