In the process wl_keyboard's version has been incremented. Given
clients get the wl_keyboard from wl_seat without a version, wl_seat's
version has also been incremented (wl_seat version 4 implies
wl_keyboard version 4).

The "release" message of wl_pointer, wl_keyboard and wl_touch introduced
in version 3 was placed first in the respective interface XML element,
causing wayland-scanner to misbehave and set the version number of the
"release" message to all subsequent messages with no explicitly specified
"since" version.

"the callback event will arrive after the next output refresh" is wrong,
if you interpret "output refresh" as framebuffer flip or the moment when
the new pixels turn into light the first time. Weston has probably never
worked this way.
Weston triggers the frame callbacks when it submits repainting commands
to the GPU, which is before the framebuffer flip.
Strike the incorrect claim, and the rest of the paragraph which no
longer offers useful information.
As a replacement, expand on the "throttling and driving animations"
characteristic. The main purpose is to let clients animate at the
display refresh rate, while avoiding drawing frames that will never be
presented.
The new claim is that the server should give some time between
triggering frame callbacks and repainting itself, for clients to draw
and commit. This is somewhat intimate with the repaint scheduling
algorithm a compositor uses, but hopefully the right intention.
Another point of this update is to imply, that frame callbacks should
not be used to count compositor repaint cycles nor monitor refresh
cycles. It has never been guaranteed to work. Removing the mention of
frame callback without an attach hopefully discourages such use.
v2: Don't just remove a paragraph, but add useful information about the
request's intent.
v3: Specify the order of posting frame callbacks.

A small step towards non-recursive build system for wayland too.

Same reason as commit cd31275f28b0a04d2ec5426dc81e875197b47e52 from weston:
The scanner needs to be good enough. If it crashes or fails to report
invalid input, that needs to get fixed.

Clarify when the pending and current buffer transform and scale values
change, and what exactly happens on commit.
This matches what Weston currently does.

"data" is the name of the void* argument in the implementation.
While we probably shouldn't use such an easily-collidable name,
just rename the callback's argument to callback_data for now.
|
|
The parameter here is an opaque integer, rather than the event serial.
The "frame" callback uses this to pass the current time of day in
milliseconds.

The sub-surface protocol was originally committed into Weston on May
10th, 2013, in commit 2396aec6842c709a714f3825dbad9fd88478f2e6. The
design for the protocol had started in the beginning of December 2012. I
think it is high time to move this into the core now.
This patch copies the sub-surface protocol as it was in Weston on Nov
15th, 2013, into Wayland. Weston gets a patch to remove the protocol from
there.
Sub-surface is a wl_surface role. You create a wl_surface as usual, and
assign it the sub-surface role and a parent wl_surface. Sub-surfaces are
an integral part of the parent surface, and stay glued to the parent.
For window management, a window is the union of the top-level
wl_surface and all its sub-surfaces. Sub-surfaces are not clipped to the
parent, and the union of the surface tree can be larger than the
(top-level) wl_surface at its root.
The representative use case for sub-surfaces is a video player window.
When the video content is given its own wl_surface, there is no need to
modify the video frame contents after decoding or copy them into a whole
window sized buffer before submitting it to the compositor. This allows
efficient, zero-copy video presentation paths, where video decoding
hardware produces a (YUV) buffer, which eventually ends up in a
(YUV-capable) hardware overlay and is scanned out directly.
This can also be used for zero-copy presentation of windowed OpenGL
content, where the OpenGL rendering engine does not need to draw or
avoid window decorations.
Sub-surfaces allow mixing different buffer types into the same window,
e.g. software-rendered decorations in wl_shm buffers, and live content
in EGL-based buffers.
However, the sub-surface extension does not offer clipping or scaling
facilities, or accurate presentation timing. Those are topics for
additional extensions.

The scanner is not very forgiving if the protocol doesn't match it's
expectations and crashes without much of a notice. Thus, validate the protocol
against a DTD.
Move the protocol subdir forward so we validate first before trying anything
else, and install the DTD so we can validate weston's protocols as well.

We missed destroy requests in the 1.0 protocol and since the scanner
generates local-only *_destroy requests in that case we can't add
destroy requests without breaking protocol. A client needs to verify
that the server provides a version 3 seat to use the protocol destructor
so the name needs to be something else than wl_*_destroy.
v2 (Rob Bradford): Rebased, bumped the protocol versions and added since
attributes to the requests.

This format is used to specify that the key button events received are not in
relation to any key map and that the codes should be interpreted directly.

for the enum entry.

This provides the ability for a client to differentiate events from

Modes are mainly meant to be used in coordination with fullscreen in
DRIVER mode, by e.g. games. For such games what they generally want
is to match some hardware mode and resize their window for that. We
don't really need to complicate this with the scaling. So, we
keep the resolutions in HW pixels, and drop the SCALED flag (as it
is now useless).
This lets you just create e.g an 800x600 buffer of scale 1 and
fullscreen that, ignoring the output scaling factor (although you can
of course also respect it and create a 400x300 surface at scale 2).
Conceptually the mode change is treated like a scaling which overrides
the normal output scale.
The only complexity is the FILL mode where it can happen that the user
specifies a buffer of the same size as the screen, but the output has scale
2 and the buffer scale 1. Just scanning out this buffer will work, but
effectively this is a downscaling operation, as the "real" size of the surface
in pels is twice the size of the output. We solve this by allowing FILL to
downscale (but still not upscale).

We usually use signed ints for things like this, to avoid
issues C sign coersion.

This adds the wl_surface.set_buffer_scale request, and a wl_output.scale
event. These together lets us support automatic upscaling of "old"
clients on very high resolution monitors, while allowing "new" clients
to take advantage of this to render at the higher resolution when the
surface is displayed on the scaled output.
It is similar to set_buffer_transform in that the buffer is stored in
a transformed pixels (in this case scaled). This means that if an output
is scaled we can directly use the pre-scaled buffer with additional data,
rather than having to scale it.
Additionally this adds a "scaled" flag to the wl_output.mode flags
so that clients know which resolutions are native and which are scaled.
Also, in places where the documentation was previously not clear as to
what coordinate system was used this was fleshed out.
It also adds a scaling_factor event to wl_output that specifies the
scaling of an output.
This is meant to be used for outputs with a very high DPI to tell the
client that this particular output has subpixel precision. Coordinates
in other parts of the protocol, like input events, relative window
positioning and output positioning are still in the compositor space
rather than the scaled space. However, input has subpixel precision
so you can still get input at full resolution.
This setup means global properties like mouse acceleration/speed,
pointer size, monitor geometry, etc can be specified in a "mostly
similar" resolution even on a multimonitor setup where some monitors
are low dpi and some are e.g. retina-class outputs.
|
|
This add a wl_output.done event which is send after every group
of events caused by some property change. This allows clients to treat
changes touching multiple events in an atomic fashion.
