* [PATCH] media: Convert to using %pOF instead of full_name

From: Rob Herring @ 2017-07-18 21:43 UTC (permalink / raw)
To: linux-arm-kernel
Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Maybe I'm missing something, but how does that work exactly? Before
the overlay is applied, the remote endpoint node (and its parent)
can't be resolved. In the commit example, the endpoint in the
media_bridge would also have to be part of the overlay. If you apply
and un-apply the overlay, then the of_node (and fw_node) in the
overlay is once again invalid. IOW, you should be in the same state as
before the overlay was applied. The node is still around because of
paranoia that actually freeing nodes would break things. It seems this
paranoia is real, so i think we need to do something to prevent this
from spreading.
Furthermore, it does not appear that any media driver supports
overlays and we have no general way to apply them in mainline yet
(other than an in kernel API). So really this scenario is not one we
have to support yet.

Commit d2180e0cf77dc7a7049671d5d57d seems to have a fundamental
misunderstanding of overlays, if I understand the implications of that
commit.
When an overlay (1) is removed, all uses and references to the nodes and
properties in that overlay are no longer valid. Any driver that uses any
information from the overlay _must_ stop using any data from the overlay.
Any driver that is bound to a new node in the overlay _must_ unbind. Any
driver that became bound to a pre-existing node that was modified by the
overlay (became bound after the overlay was applied) _must_ adjust itself
to account for any changes to that node when the overlay is removed. One
way to do this is to unbind when notified that the overlay is about to
be removed, then to re-bind after the overlay is completely removed.
If an overlay (2) is subsequently applied, a node with the same
full_name as from overlay (1) may exist. There is no guarantee
that overlay (1) and overlay (2) are the same overlay, even if
that node has the same full_name in both cases.

My understanding is that nodes from an un-applied overlay will be
freed if the expanded device tree that was used to create it has
its reference counts drop to zero. But I wouldn't count on me
remembering this correctly without actually walking through all
the code. And as far as I know, there is no example of this
in the mainline tree.

My understanding is that nodes from an un-applied overlay will be
freed if the expanded device tree that was used to create it has
its reference counts drop to zero. But I wouldn't count on me
remembering this correctly without actually walking through all
the code. And as far as I know, there is no example of this
in the mainline tree.

Commit d2180e0cf77dc7a7049671d5d57d seems to have a fundamental
misunderstanding of overlays, if I understand the implications of that
commit.
When an overlay (1) is removed, all uses and references to the nodes and
properties in that overlay are no longer valid. Any driver that uses any
information from the overlay _must_ stop using any data from the overlay.
Any driver that is bound to a new node in the overlay _must_ unbind. Any
driver that became bound to a pre-existing node that was modified by the
overlay (became bound after the overlay was applied) _must_ adjust itself
to account for any changes to that node when the overlay is removed. One
way to do this is to unbind when notified that the overlay is about to
be removed, then to re-bind after the overlay is completely removed.
If an overlay (2) is subsequently applied, a node with the same
full_name as from overlay (1) may exist. There is no guarantee
that overlay (1) and overlay (2) are the same overlay, even if
that node has the same full_name in both cases.

Indeed, the motivation of the above mentioned commit was some out of
tree driver. I don't know was the exact use case, assuming that the
endpoint in the bridge node was also part of the overlay the bridge
driver must have not been rescanning device tree after overlay un-apply
and apply. Currently there is no other way to do this than to unbind
and bind. So the bridge driver must have been referencing an already
invalid node as you point out.
I haven't been following DT overlays very closely, as Frank explains
your change seems to be actually an improvement of current code.

After such fix, I'm OK with this patch.
Are you planning to apply it on your tree, or via the media one?
I guess it is probably better to apply via media, in order to avoid
conflicts with other changes.

I'll send a new version.
