We currently hardcode a 60Hz update rate for the rdp backend.
In some cases it may be useful to override this to increase the rate
for a faster monitor, or to decrease it to reduce network traffic.

Instead of hard coding a 16ms refresh interval, use the refresh rate
from the current mode to determine when the next frame should be.
Currently, we still hard code the refresh rate, so this will end up
with roughly the same value we've been using, but in the future
we'll allow setting it via command line.

We already have a way for a single RDP client connection to be
passed from a parent process to a child using a combination
of environment variable (RDP_FD) and env var (--env-socket)
This patch allows a bound socket fd (as opposed to a client
connection) to be established in a parent process and provided
to the rdp backend. WSLg uses this to set up an AF_VSOCK
socket for communication between a Windows RDP client and a
weston compositor running under a hypervisor.

These events carry the 4th and 5th mouse buttons, so
we should propagate them. We also need to use pointer
frames to ensure the buttons are properly paired with
the pointer co-ordinates.
Unfortunately, there is no way in RDP to determine if
a mouse event and an extended mouse event should be in
the same pointer frame, so this is the best we can do.
We also enable extended mouse events so they'll be used.

This makes it easier to understand whether the compositor DMA-BUF
feedback was effective.
Signed-off-by: Simon Ser <contact@emersion.fr>
This fixes an issue when running simple-dmabuf-feedback:
"wl_display@1: error 1: invalid arguments for wl_surface@3.attach".
As we are not using create_immed request from zwp_linux_dmabuf_v1, we
can't start to use a dma-buf buffer before we process compositor's event
telling us that the creation succeeded.
This was causing problems in the following scenario:
1. buffer is marked to be recreated (because of dma-buf feedback);
2. in buffer_release() event, we destroy the buffer and recreate it;
3. after we recreate it, roundtrip is not called, as we don't want to
block during the drawing loop;
4. buffer status is not being properly tracked, so we are trying to
use a buffer before receiving the event from the compositor telling
us that the creation succeeded.
To fix this, this patch improves buffer status tracking. Now we only
pick a buffer in the drawing loop when it is available. Also, if we have
no buffers available we perform a roundtrip and try again, as we may
have recreated all of them but still didn't have the chance to process
compositor's events telling us that creation succeeded.

This is a minor re-work of how we de-activate and activate the surfaces
in desktop-shell. As activate() is being used for handling keyboard
input events, this basically rectifies that such that activation
happens only if the passed surface is different from the currently
focused surface.

Rather than punching through to set the surface as a solid colour,
attach an actual weston_buffer to it instead.
This becomes the first user of attaching non-client-generated buffers
to a weston_surface. As a result, it is necessary to introduce a
function which will allow compositors and shells to attach a buffer to a
surface. weston_surface_attach_solid() is therefore introduced as a
special-purpose helper which will attach a solid buffer to a
weston_surface.
It is not intended as a general-purpose mechanism to allow compositors
to attach client-generated buffers to surfaces, as doing so would have
unknown effects on this core part of the compositor itself.

Refactor the buffer-type check slightly so we can handle solid-color
buffers, which we do exactly nothing with.
Signed-off-by: Daniel Stone <daniels@collabora.com>
Currently solid-colour displays (e.g. the background for fullscreen
views) is implemented by a special-case weston_surface which has no
buffer attached, with a special punch-through renderer callback to set
the colour.
Replace this with a weston_buffer type explicitly specifying the solid
colour, which helps us eliminate yet more special cases in renderers and
backends.
This is not handled yet in any renderer or backend, however it is also
not used by anything yet. Following commits add support to the renderers
and backends.

When the renderer/backend indicate that they do not need a surface's
buffer content to be preserved, most often because they have copied it,
simply downgrade the buffer reference to 'will not access', rather than
drop the buffer reference altogether.
Signed-off-by: Daniel Stone <daniels@collabora.com>
In the original conception, a weston_buffer_reference indicated that the
underlying contents of the wl_buffer would or could be accessed, so
wl_buffer.release must not be sent until the last reference was
released, as the compositor may still use it.
This meant that renderers or backends which copied the buffer content -
such as the GL renderer with SHM buffers - could only send a buffer
release event to the client by 'losing' the buffer reference altogether.
The main side effect is that `weston-debug scene-graph` could not show
any information at all about SHM buffers when using the GL renderer, but
it also meant that renderers and backends grew increasingly exotic
structures to cache information about the buffer.
Now that we have an additional buffer-reference mode (still referring to
the weston_buffer/wl_buffer, but not going to access its content), we
can allow the weston_buffer_reference and weston_buffer to live as long
as the buffer itself, even if we do send a release event.
This will enable a bunch of backend and renderer deduplication, as well
as finally making scene-graph more useful.

Add a mode argument to weston_buffer_reference which indicates whether a
buffer's storage may/will be accessed, or whether the underlying storage
will no longer be accessed, e.g. because it has been copied. This will
be used to retain a pointer to the weston_buffer whilst being able to
send a release event to the client.

We currently allow a weston_buffer to outlive the underlying wl_buffer
iff the renderer/backend has cached it. Currently the 'is this buffer

itself; shift these tests to looking at the validity of the underlying
resource.

y_inverted meant that the buffer's origin was (0,0), and non-inverted
meant that the buffer's origin was (0,height). In practice, every buffer
was 'inverted' into our natural co-ordinate space that we use
everywhere.

When we first see a buffer attached, we create a weston_buffer for it.
The weston_buffer doesn't contain any useful information in and of

for SHM and dmabuf buffers; EGL buffers will follow in the next commit.

With commit 'screen-share: Add option to start screen sharing on weston
star' an section option has been added to start screen-sharing by
default on all outputs. This has the side-effect of attempting to start
screen-share on the same (RDP) output performing the screen-share. That
happens due to re-loading the screen-share module once more.

use a different configuration file to avoid that.
