pixel-formats already stores the gl_format, at least for single-planar
formats; use that instead of storing our own copies.

Instead of checking for each format whether we need compatibility
workarounds for GL implementations not supporting ES3.x or when
GL_EXT_texture_rg isn't present, have each format declare the ideal case
and fix it up later.
Signed-off-by: Daniel Stone <daniels@collabora.com>
Rather than checking all the pixel-format components which are currently
duplicated inside gl-renderer, just check for equality of the pixel
format itself, which will become useful as we remove some of the
duplicate content.
This means that the texture storage will now be reallocated when clients
switch between pixel formats which could've had compatible GL storage
(e.g. XRGB <-> ARGB) on the same surface. However this does not seem
like a case worth optimising, and simplifies the code somewhat.

Log EGL features similar to how GL ES features are logged: listing just
the ones weston tests for.
This replaces some log messages from gl-renderer.c that become
redundant or belong with EGL better.
has_native_fence_sync and has_wait_sync are not logged, because missing
them already logs warnings.

useful. Sometimes they might be interesting, so make them still

Now that the gl_buffer_state owns everything related to buffers, move
the textures from there rather than living on the surface, to join the
EGLImage and/or SHM params.
Signed-off-by: Daniel Stone <daniels@collabora.com>
Now that EGLImages are strongly associated with a gl_buffer_state, which
has a lifetime strictly bounded by a weston_buffer, we don't need to
have an egl_image wrapper having its own separate refcounting anymore.

... apart from SHM.
EGL and dmabuf buffers already have a gl_buffer_state created for them
when we first attach the weston_buffer. By turning
gl_surface_state::buffer into a pointer, we can just reference rather
than inline the gl_buffer_state.
SHM buffers are special, in that we don't keep individual copies of them
within the GL renderer. Instead, the GL surface has a texture allocated
with a shadow copy of the most up-to-date surface content. Handle this
by allocating and destroying gl_buffer_state every time we need to
respecify textures or somehow meaningfully change the parameters.
Signed-off-by: Daniel Stone <daniels@collabora.com>
Similarly to EGL buffers, store the gl_buffer_state for a dmabuf buffer
inside weston_buffer, rather than on the linux_dmabuf_buffer. This
slightly simplifies our gl_buffer_state handling, and will be used later
to eliminate the egl_image refcounting.
Signed-off-by: Daniel Stone <daniels@collabora.com>
Introduce a renderer_private hook for weston_buffer, and use this to
store a copy of the gl_buffer_state for EGL buffers (i.e. non-dmabuf, via
EGL_WL_bind_wayland_display).
As part of this, we create the EGLImage along with the weston_buffer
information, and just take a reference to it each time it is attached.
If you have bisected a failure to update surface content to this commit,
it very likely means that your EGL implementation requires images to be
recreated rather than only rebound in order to have their content
updated, which is contrary to specification.

At the moment, attach_shm() will modify the gl_buffer_state in place,
then compare it and see if it differs enough to require a new one. That
rather mixes up the old and new worlds, so quite explicitly build up a
shadow gl_buffer_state with variables first before we change the one
which already exists.

Now that we can reliably access buffer dimensions from weston_buffer,

This was only used for what was presumably an attempt at an
optimisation, to force the texture's pitch in pixels to match the SHM

Deduplicate the no-buffer and the import-fail case, and try to fall
through where we can. This will make it easier to shift the buffer
reference change later, so the attach subhandlers can reference the old

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.

Add a mode argument to weston_buffer_reference which indicates whether a
buffer's storage may/will be accessed, or whether the underlying storage
will no longer be accessed, e.g. because it has been copied. This will
be used to retain a pointer to the weston_buffer whilst being able to
send a release event to the client.

y_inverted meant that the buffer's origin was (0,0), and non-inverted
meant that the buffer's origin was (0,height). In practice, every buffer
was 'inverted' into our natural co-ordinate space that we use

When we first see a buffer attached, we create a weston_buffer for it.
The weston_buffer doesn't contain any useful information in and of
itself; that's left to renderers to populate later.
Switch this to doing it in the core at the first opportunity, at least
for SHM and dmabuf buffers; EGL buffers will follow in the next commit.
