Introduces three new structs, weston_tablet and weston_tablet_tool for the
respective devices, with the respective information as it's used on the protocol.
And weston_tablet_tool_id to track the tools of a tablet.
Note that tools are independent of tablets, many tools can be used across
multiple tablets.
The nesting on the protocol level requires a global tablet manager, a tablet
seat nested into weston_seat. The list of tablets and tools are also part of
the weston_seat.
Most functions are stubs except for the actual tablet and tablet tool
creation and removal.
This is based on patches from Peter Hutterer <peter.hutterer@who-t.net> and

We have an optimization to skip composition if there's no damage on the
primary plane and we already have a renderer buffer active. But we don't
allow this optimization if there's a pending capture task for the
output. For the renderer-based sources, that is really necessary, but
for the writeback source we should allow this optimization.

Fractional scale is increasingly common in the Wayland ecosystem. Thus,
given simple-egl's role as egl example client, implement support for
the new protocol - even though Weston itself does not support it yet.
Together with buffer_scale and buffer_transform this ensures
simple-egl provides optimally sized and oriented buffers.

A popup grab is specified to have the top most popup surface gain
keyboard focus. This means the keyboard focus should always follow the
most recent xdg_popup.grab() surface. Make sure this happens by keeping
track of the parent surface in the libweston-desktop popup grab,
updating the keyboard focus when surfaces are added and removed from the
popup chain, and restoring the keyboard focus to the toplevel when there
are no popups anymore.

Popups should have keyboard focus when active, but the toplevel window
should still appear "active". Make sure this is the case by changing the
"active" tracking to see whether any child surface has keyboard focus.

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.

There's a comment explaining how to hack the DRM-backend in order to
fake that a certain format is not supported by the KMS device. This is
useful in order to test dma-buf feedback implementations using the
simple-dmabuf-feedback client. But with recent changes on the
DRM-backend, this got outdated.
Drop this comment, as everyone interested in this client is probably
familiar enough with the DRM-backend in order to do that.
Also made some adjustments to other comments explaining how this client
works.

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.

It makes no sense to keep the scanout tranche on the dma-buf feedback if
there are no overlay planes available. So start to remove it.

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.

With this change, we expose the DRM-backend writeback source through the

For now we'll always fail writeback screenshots requests, because we

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.

NVIDIA is more pedantic than Mesa and correctly complains that `1.0f`
is not valid syntax in the OpenGL ES Shading Language version 1.00.
And we are indeed using SL version 1.00 by virtue of using an ES 2.0
context.
So use the syntax compatible with the context we've created.

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.

Input panels are used for complex text composition for CJK alphabets and for
onscreen keyboards. Support for this is already implemented in libweston and
the desktop shell.
This adds extends the IVI shell to add support for input panels as well. The
low-level parts are implemented in the IVI shell. The positioning of the input
panels is delegated to the controller.
Support for input panels and the relevant protocols is only enabled if the
controller attaches a listener to the new signals.

This makes it possible for the controller to distinguish different surface

shell_surface_send_configure() should only be called for ivi surfaces. Other (or
no) *configure() calls are needed for other types of surfaces.
Make sure that get_ivi_shell_surface() returns NULL if the surface is not an ivi
surface. And don't ignore wrong surfaces but assert instead to make it obvious
that new surface types need special handling in ivi_layout_surface_set_size().

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().

This patch introduces a small library wrapper around XCB to be used in
Xwayland tests.
It's being designed such that we do not advance without accounting for
all X11 events when changing the window state. It adds a fence that
waits for all events to be processed, and only after all the events have
been accounted for, to proceed further, resuming execution of the
tests.
This works by keeping a tentative_state list for the client and a
window state that gets applied when the event we waited for has been
received.
This is useful in test clients, which could verify at the end after
receiving all events that the correct state has been applied. Acts as a
way to verify that the we never get or have a different state than the
one we expect.
With it, this converts test-xwayland to using libxcb (together with
xcb-cursor-dev) rather than using Xlib, and with it it removes any Xlib
dependency we might have in the tests.
This only adds support for map/unmap/create/destroy/property notify.
A follow-up would be to expand this library to track window movement
and resizing.

In future code the window link will end up in a state where it may or may
not be on the unpaired_window_list and we'll want to go from that state
to one where it's definitely not on the list.
Initting the list after removal (in these two places) allows us to
unconditionally remove it later.
