* speeds up incremental builds as changes to a header will not always
need the full mocs_compilation.cpp for all the target's headers rebuild,
while having a moc file sourced into a source file only adds minor
extra costs, due to small own code and the used headers usually
already covered by the source file, being for the same class/struct
* seems to not slow down clean builds, due to empty mocs_compilation.cpp
resulting in those quickly processed, while the minor extra cost of the
sourced moc files does not outweigh that in summary.
Measured times actually improved by some percent points.
(ideally CMake would just skip empty mocs_compilation.cpp & its object
file one day)
* enables compiler to see all methods of a class in same compilation unit
to do some sanity checks
* potentially more inlining in general, due to more in the compilation unit
* allows to keep using more forward declarations in the header, as with the
moc code being sourced into the cpp file there definitions can be ensured
and often are already for the needs of the normal class methods
ClientBufferIntegration was introduced to work around the fact that some
client buffers are not created by us.
In addition to that, DisplayPrivate::registerClientBuffer() was
introduced to register client buffers created by us.
This change get rids of the ClientBufferIntegration type and further
simplifies the ClientBuffer type to make wayland-specific client buffer
code less messier.
As of nowadays, most clients have switched to the linux-dmabuf protocol,
except Xwayland, which still needs the wl-drm protocol.
On the other hand, we would like to unify some buffer handling code.
There are a few options:
- drop the support for wl-drm protocol. Not doable, because Xwayland
still needs it, even though it uses the linux dmabuf feedback protocol
too
- re-implement the wl-drm protocol
- re-implement the minimal part of the wl-drm protocol needed by
Xwayland
This change goes after the third option. Only the node name and the
capabilities will be sent. The buffer factory requests are not
implemented, but they can be if we discover that some clients need them.
With the EGLStreams support gone, we can restore the correct type check
for wl_drm client buffers. The spec suggests to query the
EGL_TEXTURE_FORMAT attribute to determine whether the specified wl_buffer
is a wl_drm buffer.
I am trying to build against a Qt built without OpenGL. In that case, the
openGL headers have not been included and therefore GLboolean is not
defined. Use EGLBoolean to match the EGL prototype.

Currently, the BufferInterface encapsulates all the kinds of client
buffers. This has become a somewhat annoying issue as we want to
reference the shm pool if a shm buffer is destroyed, or have custom
buffer readiness logic for linux dma-buf client buffers.
Implementing all of that with the current abstractions will be
challenging as there's no good separation between different client
buffer types.
This change splits the BufferInterface class in three sub-classes -
DrmClientBuffer, LinuxDmaBufV1ClientBuffer, and ShmClientBuffer.
In addition to that, this change fixes the broken buffer ref'ing api.
