e3b6d04017 color-lcms: refactor away setup_seach_param()
To me, the use of setup_search_param() makes the code harder to
understand than it needs to be. Replacing that function with open-coding
the struct cmlcms_color_transform_search_param initialization makes it
more clear that:

- get_surface_color_transform is the only one that actually uses a
  surface to initialize it

- get_blend_to_output does not use an input profile at all

- get_sRGB_to_output and get_sRGB_to_blend hardcode the sRGB profile
  like they should

dfba19abde color: simplify color manager API with weston_output_color_outcome
I am going to need to add yet another output property to be set by a
color manager: HDR Static Metadata Type 1. With the old color manager
API design, I would have needed to add the fourth function pointer to be
called always in the same group as the previous three. This seemed more
convoluted than it needs to be.

Therefore collapse the three existing function pointers in the API into
just one that is resposible for setting up all three things.

6c0524fd80 libweston: add struct weston_output_color_outcome
This new struct collects all the things that a color manager needs to
set up when any colorimetry aspect of an output changes. The intention
is to make the color manager API less verbose.

In this first step, the new struct is added and replaces the fields in
weston_output.

The intention is for the following color manager API changes to
dynamically allocate this structure. Unfortunately, until that actually
happens, we need a temporary way to allocate it. That is
weston_output::colorout_, which will be removed in the next patch. This
keeps the patches more palatable for review at the cost of some
back-and-forth in code changes.

This is a pure refactoring, no functional changes.

e6a9e3c4ee backend-drm: default to XRGB2101010 for HDR
Trying to do HDR with XRGB8888 is a bit like using RGB565 on SDR: you
get visible color quantization and banding in gradients (without dithering
which Weston does not implement yet, and might not work too well for HDR
anyway).

Therefore, on any HDR mode, default output framebuffer format to 10 bpc
instead of 8 bpc.

Ideally we'd also optionally try 16F or 16 bpc formats, but automatic
fallbacks for those are more complicated to arrange. You can still
configure 16F or 16 bpc manually.

This patch also moves the default format setting from
drm_output_set_gbm_format() to drm_output_enable(), because setting the
default now requires eotf_mode. Frontends may call set_gbm_format()
first and set eotf_mode next. This does create an awkward situation for
outputs that a frontend disables and re-enables. This patch here makes
sure that the old output configuration remains, but changing eotf_mode
may not change the default format. One needs to call
set_gbm_format(NULL) to re-evaluate the default format. Resetting the
format on drm_output_deinit() would lose the current setting.

DRM_FORMAT_INVALID was introduced in libdrm 2.4.95 which we already
hard-depend on.

5151f9fe9e backend-drm: program HDR_OUTPUT_METADATA
Program the connector property HDR_OUTPUT_METADATA based on the EOTF
mode of the output.

For now, this changes only the EOTF. The colorimetry and luminance are
left undefined, to be filled in by later patches. This should still be
enough to put a video sink into HDR mode, albeit the response is
probably unknown.

drm_output keeps track of the currently existing blob id. If the blob
contents need to be re-created, this blob would be destroyed and the
field set to zero. In this patch, there is no provision for runtime
changing of HDR metadata, so there is no code doing that.

Destroying the blob at arbitrary times is not a problem, because the
kernel keeps a reference to the data as long as the blob id remains with
KMS.

yes, pretend that EDID claims support for all EOTF modes and update the
head supported EOTFs mask accordingly. If not, then only SDR is

later.

6914064066 backend-drm: add HDR_OUTPUT_METADATA definitions
These are fallback definitions in case libdrm is not new enough.
They are copied from libdrm 2.4.107.

struct hdr_output_metadata defines the contents of the blob to be used

5f9b68d68f libweston: introduce weston_eotf_mode
This is the switch to turn HDR mode on.

The values in the enumeration come straight from CTA-861-G standard.
Monitors advertise support for some of the HDR modes in their EDID, and
I am not aware of any other way to detect if a HDR mode actually works
or not. Different monitors may support different and multiple modes.
Different modes may look different. Therefore the high-level choice of
how to drive a HDR video sink is left for the Weston frontend to decide.

All the details like what HDR metadata to use are left for the color
manager.

This commit adds the libweston API for backends to advertise support and
for frontends to choose a mode. Backend and frontend implementations
follow in other commits.

The frontend API does not limit the EOTF mode to the supported ones to
allow experimentation and overriding EDID.

0277046a1d simple-egl: Defer EGL surface/window creation
Rather than creating the wl_egl_window at the same time as wl_surface,
do it after we get the first configure event.

With it, we also defer eglMakeCurrent() as according to the spec, the
first time a OpenGL or OpenGL ES context is made current, the viewport
and scissor dimensions are set to the size of the draw surface.

This is particulary important when attempting to start simple-egl either
as fullscreen or as maximized, as not doing so will either incorrectly
commit a buffer with the original dimensions, and later on to resize to
the correct dimensions (which is the case for fullscreen), or it will
terminate the wayland connection abruptly due to xdg-shell protocol
violation, with a mismatch for the client's geometry (the case for
maximized).

06472fb136 desktop-shell: Delete Exposay
Exposay was done as a showcase for what we could do with Weston and an
efficient compositing pipeline. This was mostly with the old
vendor-specific Raspberry Pi backend which could actually process that
many surfaces bypassing the GPU.

Given enough bitrot, Exposay is now pretty exemplary as what _not_ to do
in a Weston shell - particularly the way it manipulates existing
weston_views rather than create its own non-destructive stack.

As it's annoying technical debt, a terrible example to others, and not a
very compelling showcase in 2022, just delete it.

7724c5ea38 clients/simple-dmabuf-feedback: do not use buffer before compositor's response
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.

4d426ab6b1 shell: Explicitly use solid weston_buffers
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.

82b646728c backend-drm: Handle solid-colour buffers in state propose
When we're checking to see if a view is suitable to go on a plane, check
for (and reject) solid-colour buffers.

b38b735e20 backend-drm: Remove Pixman conditional for keep_buffer
The Pixman renderer keeps its own reference to buffers when attached to
surfaces, through its surface state: just use that instead.

493a4c013e noop-render: Allow solid-color buffers
Refactor the buffer-type check slightly so we can handle solid-color
buffers, which we do exactly nothing with.

43715ff0c0 weston_buffer: Add solid buffer type
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.

7a27f6cbe4 compositor: Downgrade rather than drop buffer reference when copied
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.
