fea8ebcca9 cursor-renderer/native: Store struct in CRTC private
In this struct, for now only the buffer is stored, but it'll be used for
more state in later commits.

447c51e68e renderer-native: Always post device wide updates during mode set
Don't mode set each CRTC in separate KMS updates, as reconfiguring one
CRTC might cause other CRTCs to be implicitly reset thus as well,
causing KMS return EBUSY if using atomic modesetting.

Prepare for this by compositing each CRTC first including adding steps
to the KMS update, but wait until all views has rendered at least once
before posting the initial update. After this each CRTC is posted
separately.

Using EGLStreams instead of normal page flipping seems to fail when
doing this though, so handle that the old way for the EGLStream case,
i.e. eglSwapBuffers() -> mode set with dumb buffer -> eglStream
"acquire" (resulting in page flip under the hood).

For this we also introduce a new error code so that we don't use client
buffers when doing mode sets, which could accidentally configure the
CRTC in a way that is incompatible with the primary plane buffers.

Do the same also when we're in power save mode, to only have one special
case path for this scenario in the regular swap-buffer path.

92d4cb5184 clutter/frame: Make rendering backends set the frame result
Instead of setting the frame result in the most generic layer, have the
backends do it themselves. This is necessary to communicate that a
swap-buffer call didn't really succeed completely to present the swapped
buffer, e.g. errors from KMS.

249512b068 cogl/onscreen: Add opaque user_data pointer to onscreen present calls
This argument is intended to be used by clutter to be able to
communicate with the onscreen backend, that happens to be the native
backend. It will be used to pass a ClutterFrame pointer, where the
result of page flips, mode sets etc can be communicated whenever it is
available.

72b35e07c0 clutter: Introduce ClutterFrame
ClutterFrame aims to carry information valid during dispatching a frame.
A frame may or may not include redrawing, but will always end with a
result.

A asynchronous page flip, for example, will result in a
CLUTTER_FRAME_RESULT_PENDING_PRESENTED, while a frame that only
dispatched events etc will result in CLUTTER_FRAME_RESULT_IDLE. Instead
of this being implicit, make the ClutterStageWindow implementation
handle this itself.

b693e58c53 kms/update: If reassigning a plane handle the fb changed flag
If we reassign e.g. a cursor plane twice before it's updated, we need to
make sure the 'fb-unchanged' flag is correctly handled, so that if we
changed the fb first, then updated the assignment again only changing
the position, the new assignment should not be flagged with
fb-unchanged.

3bad37482d kms: Add way to preserve failed update
When we e.g. try to post an direct client buffer scanout update, it
might arbitrarily fail; when this happen we still will want to post the
rest of the update when we try again after having composited the primary
plane. To do this, add a way to preserve the metadata of an update if it
failed, only dropping the failed plane assignments. This involves
unlocking a previously locked MetaKmsUpdate, so that e.g. a new primary
plane can be assigned.

afd0a272cd kms/update: Add way to receive result from later posted update
Something might want to affect the next update that is going to be
posted, but without posting it immediately. For example, changing the
cursor might need to wait for mode setting. Make it possible to get
feedback from posting the update, in order to gracefully handle any
errors.

Note, the API for notifiying about results take out the result listener
from the update, and notifies them in an open coded for loop. The reason
for this is that in the next commit we'll sometimes reuse updates, and
we only want notify about the results once.

a2b8668544 kms/impl: Dont discard page flips in callback when failed up front
If posting an update resulted in an immediate error, don't communicate
this failure using the page flip feedback callbacks, but directly as a

5ba2d79076 kms/update: Make custom page flip be per update
Custom page flips are meant to allow using e.g. EGLStream API to

directly. This is really something that is specific to a device, so
instead of making part of the page flip API, make it a configuration of
the update itself.

84bde805fe native: Consolidate DRM buffer management to MetaDrmBuffer types
This commit consolidates DRM buffer management to the MetaDrmBuffer
types, where the base type handles the common functionality (such as
managing the framebuffer id using drmModeAdd*/RMFb()), and the sub types
their corresponding type specific behavior.

This means that drmModeAdd*/RmFB() handling is moved from meta-gpu-kms.c
to meta-drm-buffer.c; dumb buffer allocation/management from
meta-renderer-native.c.

37fe30c515 kms/update: Make each MetaKmsUpdate update a single device
For now feedbacks from an update are combined, meaning we might lose
error information. The feedback API may have to be reconsidered and
redesigned when planes gets a more front seat position.

This means we need to avoid trying to post updates if we're in power
save mode, as it may be empty.

Note that this is an intermediate state during refactoring that aims to
introduce atomic mode setting support, and we'll stop combining
feedbacks completely in the future.
