When doing plane selection for an output CRTC check if the plane
already has a CRTC attached and if so prefer that plane only for
the corresponding CRTC.
This prevents changing a CRTC's primary plane when it is active
which is not allowed by the DRM framework.

We log the reasons why the fb of a certain view was not placed in an
overlay plane and use that for debug purposes. With these reasons we
also decide if the scanout tranche should be included on the dma-buf
feedback or not. For instance:
1. If the reason is the incompatibility between the format/modifier
pair of the fb and those supported by the KMS device, the scanout
tranche is added and feedback is re-sent (so that the client can
re-allocate with parameters that makes it eligible for direct
scanout).
2. If the reason is because we have no overlay planes available, the
scanout tranche is useless. So the scanout tranche is removed and
the feedback re-sent (so that clients can re-allocate with
parameters optimal for the render device).
Also, when we detect that a view is eligible for direct scanout, we
don't even consider sending new feedback, as our interpretation of the
dma-buf feedback spec was that we should avoid bothering clients with
new feedback when they are already hitting direct scanout.
After some discussions and clarifications regarding the spec, we've
realized that Weston should start to also include the scanout tranche
even when the compositor is able to place client's content on overlay
planes. Basically, because this gives a chance for clients to
re-allocate with the proper parameters (not only format/modifier pair,
but also the target_device and the flags) from the scanout tranche. In
this patch we start doing this.

wayland_output_destroy_shm_buffers() is called immediately before
output_destroy() of the renderer is called. And for the pixman renderer all
renderbuffers must be destroyed before the output can be destroyed.
Also, weston_renderbuffer_unref() is not called when the buffer is released
because buffer->output is now NULL, so the renderbuffer would be leaked.
So just unref the renderbuffer immediately. Set it to NULL to avoid unreffing it
again should wayland_output_destroy_shm_buffers() be called again before the
buffer is released. This can happen during an xdg-shell resize.

The state does not own the fd. This is usually not a problem, because the
in_fence_fd of the state is assigned during drm_assign_planes() and then
immediately used in drm_repaint_flush(). It cannot be closed in-between.
However, in the fallback path in drm_output_start_repaint_loop(), the state is
duplicated. At this point in time, the in_fence_fd may be invalid because it was
replaced in a new commit of the corresponding surface.
The plane state was already committed to the kernel when it is copied, so the
fence is no longer needed. So just clear it.
Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
With multiple DRM devices, the state for one device may be empty during
repaint_flush(). This can happen for example if an output of one device triggers
the repaint and there are no screens attached to the other device and therefore
no active outputs.
The atomic commit will actually fail because the commit contains the
DRM_MODE_PAGE_FLIP_EVENT flag but no CRTCs.
Avoid this by skipping the commit entirly. There is nothing to to anyways.

With some displays connect, disconnect, connect events can happen is a very
short amount of time. When this happens, the output global may already be
destroyed when a client tries to bind it. As a result, the client is
disconnected with a protocol error. See [1] for more details on the general
problem.
To mitigate this problem call wl_global_remove() first and call
wl_global_destroy() several seconds later. This is inspired by the
implementation for the same problem in wlroots.

Since the logic of pointer constraints assumes a valid view throughout, add a
signal to disable constraints when its current view is unmapped by Weston.
The assumption that a previously unmapped view is valid already leads to the
constraints code crashing. This can happen when attaching a NULL buffer to the
surface and commiting, which effectively unmaps the view with the side effect of
clearing the surface's input region, which is then assumed valid inside
maybe_warp_confined_pointer().

Additional devices don't have a gbm device. Therefore, we cannot create gbm bos
for the cursor.
If the output device differs from the gbm device, fall back to the allocation of
a dumb buffer for the cursor on the output device. Update the cursor sprite with
a memcpy to the already mapped dumb buffer that belongs to the current cursor.

If the GBM bo was allocated on a different device than the device that is used
for the fb, we have to import the fd first and update the handle.
Use drmPrimeFDToHandle directly instead of using a gbm device for the scanout

not available for devices that only support scanout.

Weston uses a cached drm_fb when a view is shown multiple times. If the view is
shown on multiple outputs backed by different DRM devices, Weston returns the
cached drm_fb for the first device that was used for the import. This causes a
failure when adding the fb to the other device.
Use a list of all drm_fbs to cache the buf_fb per device, and check for the
device before reusing a drm_fb.

Now that struct weston_renderbuffer is refcounted, hold a reference for
renderbuffers on the pixman_output_state::renderbuffer_list. This allows
backends to destroy the renderer output state and release renderbuffer

To avoid breaking resizing, We also have to drop the renderbuffer list
during pixman_renderer_resize_output(). The backends have to create new

In IVI, there are several displays connected to a SoC. These displays
are just driven by differential pairs (LVDS, FPD-Link, GMSL) and powered
centrally. To reduce power comsumption when user inactivity timeout
happended on the display, there is a need to cut down pixel clock from
SoC. Then, if any input events happend on the display, it should become
active again.
Currently, controlling the compositor outputs doesn't happen independently
but rather globally, and outputs repaints are based on the compositor state
This is necessary to have an API that can force the power state of an
output to off via DPMS mode while all other compositor outputs remain
unaffected.
