d59e58bb79 compositor: Pass the length to opem_stream for one shot scene-graph
Rather than passing a NULL use sizeloc to pass the size. Otherwise
fflush(3) and fclose(3) would die out crashing in libc.

Use size also when printing out to a subscriber.

366e045b54 gl-renderer: split create_capture_task() for sync fence and timer
For now this doesn't bring any benefits besides making
gl_renderer_do_read_pixels_async() easier to read. But in the next
commits this will be important.

This allows callers to decide if they want to use a timer when they fail
to get a sync fence for a capture task. For SHM tasks we always fallback
to a timer, but for dma-buf we will not allow the fallback path.

25bb9d32b1 gl-renderer: allow to create gl_capture_task of dma-buf type
For now we support creating gl_capture_task only for SHM buffers. This
is used when the GL renderer pulls an output capture task from the
queue and its buffer type is SHM.

In the next commits we'll add support to allow output capture tasks to
be created with dma-buf buffers, so we need to extend gl_capture_task to
support that as well.

Differently from the SHM case, for dma-buf we don't have to do any copy.
The gl_capture_task is created just to wait for the blit to finish, and
then retire the output capture task.

b88695e3d5 compositor: Update transform in weston_coord global converters
I added these assert()s and have regretted it ever since. I'm sorry.

They've led to a bunch of places that just cargo-cult call
weston_view_update_transform() immediately after dirtying the transform,
as well as a lot of very carefully chosen places that took far too long to
sort out.

weston_view_update_transform() is an immediate return if the transform
isn't dirty, so let's just update them here instead of making everyone
think really hard about when to call weston_view_update_transform().

This should let us remove a few transform updates, and should
make the weston_coord functions a little easier to use.

d67f204388 tests: Don't free-run refresh in client-buffer test
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.

04a85ab71c drm: use output capture task destroy listener for writeback
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.

a222e4c44b drm: retire writeback capture task if another is in progress
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.

35d35f31ff drm: make writeback format negotiation more robust
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.
