Some drivers allow a planes-only state as long as something covers
the entire CRTC, and some allow planes-only state even with only
partial coverage.
If we have an fb that we'd like to put on the primary plane, but can't,
we might as well try it on an overlay anyway and see if we can build a
planes-only state without a primary.

While not as weird as the cursor plane, the primary plane's case is
pretty weird. Pull it out of the loop and handle it early.
This is really intended to be a step torwards building a planes-only
output state without a primary plane in it at all.

When a paint node is drawing rotated content, it's treated like its axis
aligned bounding box. Even if it only contains fully opaque content,
the parts of the axis aligned bounding box outside of that content
are not opaque.
We need to ensure we don't claim a paint node that isn't axis aligned
is fully opaque, or we'll improperly update regions outside of the
really opaque content.

It makes more sense to update the transform than to bail.

The client-buffer test was setting the desired output refresh rate to
the highest possible, posting a new buffer to the screen, waiting for
the frame callback, then requesting a screenshot be taken.
This was not necessary (we already have a mode for tests which only want
screenshots and not a free-running refresh), and also harmful in that it
setting up a potential race.
When gl-renderer gets asked to repaint with nothing to show, it tries to
read back the GL fence status after the dmabuf has signalled. On drivers
with the threaded context enabled, the GL fence would not be readable,
even if the attached dmabuf was.
The easy fix to this is to just not free-run refresh.

As weston_surface_attach_solid() can change quite a lot about a surface,
we need to mark it as dirty.
Signed-off-by: Daniel Stone <daniels@collabora.com>
transform_damage() returns an allocated set of quads; if a surface had
both opaque and blended regions, we were overwriting the
previously-allocated set of quads for the blended region.
Luckily, transform_damage() doesn't need to be called twice anyway, so
we can fix this by only calling it once in the first case.

No behavior changes; this is a follow-up of "drm: handle client buffer
destroyed while writeback scheduled".
That commit protects against clients disconnecting while a writeback job
is scheduled, which could otherwise lead to crashes if the buffer is
destroyed before the wb job completes. However, output capture provides
the same functionality: it listens to the client buffer destroy event to
retire the capture task.
Instead of listening to the wl_buffer destroy event, simply listen to
the capture task destroy event. GL renderer already follows this
pattern, and now DRM aligns with it.

YUV420_8BIT and YUV420_10BIT are special DRM formats, which exist to
allow for NV12/P010-alike formats having combined storage for luma &
chroma, rather than split planes.
This is notably used to support AFBC compression for YUV buffers, as
seen with at least Hantro codec engines and Mali GPUs.

Before "drm: make writeback format negotiation more robust", pulling a
writeback capture task while another writeback was in progress could
lead to a crash.
That commit avoids the crash, but it relies on
drm_output_find_compatible_writeback() to fail if a writeback task is
already in progress, as the majority of hardware probably support a
single writeback connector compatible with the CRTC.
Although unlikely, hardware may support more than one writeback
compatible with the CRTC. That would break our code, as our writeback
implementation does not support simultaneous writeback tasks per output.
This adds an explicit check and retires the writeback task if there's
already another writeback in progress.

Currently drm_output_get_writeback_formats() returns the formats
supported by a single writeback connector compatible with output->crtc.
This list is used to populate struct weston_output_capture_source_info
through weston_output_update_capture_info().
Later, when pulling writeback capture tasks, we call
drm_output_get_writeback_formats() again. However, as
drm_output_find_compatible_writeback() skips writeback connectors in
use, the returned format list may now differ.
Also, when selecting a writeback connector we implicitly rely on
drm_output_find_compatible_writeback() returning the same connector as
before, without verifying that the chosen connector supports the format
of the buffer provided by the client.
Make drm_output_get_writeback_formats() return the union of formats
supported by all writeback connectors compatible with output->crtc. This
makes the returned format list deterministic, regardless of whether a
writeback connector is currently in use. Although most hardware probably
supports a single writeback compatible with the CRTC, this is a good
change as it makes the code more generic and robust.
Also, add a new format param to drm_output_find_compatible_writeback(),
so now the the selected writeback can be validated against the requested
format.
The main benefit of this patch (and the reason why I wrote) is enabling
us to fix an issue when a writeback task is already in progress and
additional ones are requested:
1. weston_output_pull_capture_task() depends on the writeback format
list
2. if a writeback is already in progress,
drm_output_get_writeback_formats() returns NULL (assuming there's a
single writeback connector).
3. weston_output_pull_capture_task() crashes Weston, as the list of
writeback formats we pass does not match the one stored in struct
weston_output_capture_source_info.
With the format list now deterministic, we'll be able to safely pull the
capture task and retire it. The next commit implements this behavior.

Currently when a client buffer gets destroyed, the output capture task
gets destroyed with weston_capture_task_buffer_destroy_handler().
The problem is that we may have a writeback task scheduled, so
wb_state->ct would be pointing to a ct that has already been retired
and destroyed.
In this commit we start handling this case.

The intention is that you should be able to replace these with the
pipewire-backend that you can load together with the DRM-backend. The
functionality should be equivalent, but the libweston software
architecture becomes more maintainable for upstream. Also the
pipewire-backend is not tied to the DRM-backend, and can work with any
other backend and even alone.
Once the remoting and pipewire plugins are gone, we can remove the
virtual output API from DRM-backend.

This was the original video recorder completely in software and with a
custom file format. It is no longer useful to keep. It used the old way
of getting screenshots: hooking to weston_output::frame_signal and
calling weston_renderer::read_pixels(). This old way stalled Weston
until the GPU work was complete, and supported only wl_shm buffers.
Nowadays video recording should be arranged with the pipewire-backend
which supports dmabuf delivery.

Since glibc version 2.43, bsearch may return const void * instead of
void * when the input array is const:
"For ISO C23, the functions bsearch, memchr, strchr, strpbrk, strrchr,
strstr, wcschr, wcspbrk, wcsrchr, wcsstr and wmemchr that return
pointers into their input arrays now have definitions as macros that
return a pointer to a const-qualified type when the input argument is a
pointer to a const-qualified type."
So change variable that receives the return value from bsearch to const,
as the input array has the const qualifier. This fixes a "discards const
qualifier from pointer" error.
