31 is changed, only the respective qgraph driver node has to be adjusted.
43 A node can be of four types:
50   instantiated when a node consumes or produces it.
99 Command line is built by using node names and optional arguments
104 - ``in node``      : created from the node name. For example, machines will
107 - ``after node``   : added as additional argument to the node name.
114   after the destination node pointed by
118 - ``before node``  : added as additional argument to the node name.
122   is going to add attributes before the destination node
124   helpful to commands that are not node-representable,
156 up its qgraph node correctly. It can also happen if the necessary machine type

195 The ``arm/raspi2b`` machine node is listed as "UNAVAILABLE". Although it is
196 reachable from the root via '' -> 'arm/raspi2b' the node is unavailable because
205 availability of each node in the path in the "ALL QGRAPH NODES" output. The
206 first unavailable node in the path is the reason why the test is unavailable.
225 - Create the ``x86_64/pc`` machine node. This machine uses the
234 - Create the ``sdhci-pci`` driver node, representing ``QSDHCI_PCI``.
240 - Create an ``arm/raspi2b`` machine node. This machine ``contains``
241   a ``generic-sdhci`` memory mapped ``sdhci`` driver node, representing
245 - Create the ``sdhci`` interface node. This interface offers the
253 - Create the ``sdhci-test`` test node. The test ``consumes`` the
