Instead of crashing because a nullptr property gets accessed, use
an explicit error message and ignore the offending object. This also
acts as documentation
DrmPipeline is now what contains all the thing related to drm calls,
instead of DrmOutput. This allows for some more flexibility and tidies
the code up a bit. Additionally instead of rolling back changes if
presentation fails, changes are directly tested with atomic test only
commits.
This reverts commit 5a22deda3b.
We still need more work to finish the DrmPipeline. At the moment, there
are a few major issues, e.g. some outputs not turning on, output
transforms not working correctly, a crash when changing dpms mode.
Let's merge this change back once all major issues are fixed and after
more testing.
DrmPipeline is what now contains all the drm bits related to
modesetting and presentation, instead of that being in DrmOutput.
This gives a lot more freedom for managing drm resources and
enables far better usage of the atomic API with guaranteed
immutability for failed tests.
The value that the DrmCrtc::resIndex() function returns is better known
as "pipe index." This change renames the method to match the terminology
used by kernel developers and other compositor developers.
Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.
This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.
We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
