As weston_compositor_build_view_list() marks all the outputs needing a
paint node rebuild of the re-order list, embed the paint node status
update to ALL_DRITY into straight into weston_output_build_z_order_list().
This way we'll latch it on the view list rebuild.

This de-couples the compositor view build list from the paint node
ordered list to allow a more finer grain over what lists we need to
rebuild upon repaints.
As a consequence to that this avoids a trip over from the compositor
when paint nodes are destroyed and no longer re-created upon rebuilding
the view list.

The following config allows to mirror the LVDS output to VNC:
|[output]
|name=LVDS-1
|transform=rotate-270
|
|[output]
|name=vnc
|mirror-of=LVDS-1
However, the current code only takes the scale into account, not the
relative transformation. In case of rotate 90 or 270 the width and height
have to be swapped. Add it.

This was brought up in issue 1063. The assertion in
weston_presentation_feedback_present_list() will trigger randomly during
repeated suspend/resume testing, presumably while a client is animating
and asking for presentation feedback.
drm_output_start_repaint_loop() has a path where drmWaitVBlank() is able
to pull a good timestamp for the last vblank. This results in a call to
weston_output_finish_frame() with a good timestamp and
WP_PRESENTATION_FEEDBACK_INVALID in the flags.
Previously it was assumed that in such case the presentation feedback
list cannot have any entries. This assumption is false. It is possible
that while the output is in idle state, a client will post an update to
a surface and ask for presentation feedback on it. This should trigger
drm_output_start_repaint_loop() with a non-empty feedback list.
It is unclear why this problem was not seen in the wild much more often.
Start-repaint-loop does not present anything by definition, it only acts
to synchronize the output repaint loop with the (hardware) scanout
cycle. Therefore no feedback must be sent there. As
WP_PRESENTATION_FEEDBACK_INVALID flag indicates no feedback must be
sent, use it to avoid calling
weston_presentation_feedback_present_list().

Deprecate the screenshooter recording mode, with the intention of

The DRM backend has had a VA-API recorder for a while, which pushes the
frames from every redraw into libva for compositor-side recording.
Implementing this manually in the compositor, and configuring it, is
kind of pain. We now have the PipeWire backend which can do
screencasting in a much more flexible way without having to push
everything into the compositor itself, and without having to hardcode
support for one particular encoder framework.

to visually identify/debug clients which have been offloaded to

Although Vulkan's renderbuffers are dmabufs, the difference between a
client dmabuf and a backend-allocated dmabuf is a very meaningful one.

The DRM documentation states:
> Unless explicitly specified (via CRTC property or otherwise), the active
> area of a CRTC will be black by default. This means portions of the active
> area which are not covered by a plane will be black, and alpha blending of
> any planes with the CRTC background will blend with black at the lowest zpos.
See https://dri.freedesktop.org/docs/drm/gpu/drm-kms.html#plane-abstraction
This means the view for the primary plane does not need to cover the
whole output and black areas of the scene-graph can be left out.
Doing so has various benefits - most importantly it:
1. allows us to use the plane-only path in more situations and with one
less plane, reducing memory bandwidth usage.
2. opens the path to offload arbitrary background colors in the future.
Iterate over the all visible paint nodes, remove solid-opaque-black
views so they are not considered for plane assignment and aggregate a
region that is later used to assign the primary plane.

This changeset adds three variants of the U.S. Dvorak layout to the
table that is used to map a keyboard ID in the RDP backend to an Xkb
configuration. This makes it possible to have these variants
propagated seamlessly from an RDP client into the Wayland compositor.
As the backend-rdp module requires at least version 2.3.0 of the
FreeRDP library to build, the symbols for these variants is already
present in include/freerdp/locale/keyboard.h, included by rdp.h here,
and in libfreerdp/locale/xkb_layout_ids.c which translate the selected
layout in Xkb into the keyboard ID sent over the wire for the RDP
protocol.

We've been clobbering non-solid buffers with solid buffer attachment in
situations where we override the real buffer with a placeholder.
If the reason (punch hole, censor) that led to the placeholder is no
longer in effect, and new buffer is attached, we won't render what we should.
Instead, let's not attach anything for the paint node draw_solid case, and
allow gl_buffer_state be NULL when the real buffer is solid. gl_buffer_state
can then always be the correct state for the real buffer, even if we don't
use it.

Previously, inverse_evaluate_lut1d was called 3 * len^3 times. Now it is
called only 3 * len times with the help of pre-computed arrays for red
and green channels. Blue channel does not need an array, because there
were no redundant computations. This is a significant win.
Also, allocate a temporary array rgb_in, so cmsDoTransform() can be
called in batches of len triplets. This seemed to be not that big win. I
tried running cmsDoTransform() over len^2 triplets, but that did not
seem to improve performance.
The test I used creates two 3D LUTs, hence two times for a single run.
My representative timing test results per one 3D LUT:
- before: 16 ms and 19 ms
- after: 7 ms and 10 ms
The measurements were done with this patch:

uint32_t len_shaper, float *shaper,
uint32_t len_lut3d, float *lut3d)
{
struct cmlcms_color_transform *xform = to_cmlcms_xform(xform_base);
struct weston_compositor *compositor = xform_base->cm->compositor;
bool ret;
+ struct timespec begin, end;
+ unsigned i;
- ret = build_shaper(xform->lcms_ctx, xform->cmap_3dlut,
+ clock_gettime(CLOCK_MONOTONIC, &begin);
+ for (i = 0; i < 100; i++)
+ ret = build_shaper(xform->lcms_ctx, xform->cmap_3dlut,
len_shaper, shaper);
if (!ret)
return false;
- ret = build_3d_lut(compositor, xform->cmap_3dlut,
+ for (i = 0; i < 100; i++)

Future development will need to evaluate pipelines with curves and

operate on arrays of vec3.
Its currently only caller, weston_color_curve_to_3x1D_LUT(), is modified
to employ a temporary array for the API impedance mismatch. This
workaround will be removed later as weston_color_curve_to_3x1D_LUT()
itself will be converted to operate on vec3 arrays.

In color-operations we need only one call to the elementary function
