See the spec at [1]. tl;dr EGL has terrible defaults: eglTerminate()
may have side-effects on completely unrelated EGLDisplay objects.
This extension allows us to opt-in to get the sane behavior:
eglTerminate() only free's our own EGLDisplay without affecting
others.

This is documented to reset the gamma LUT, but we don't handle this
properly.
While at it, make sure we leave wlr_output.pending in a good state
on allocation failure.

Be consistent with other headers.

wlr_buffer.c is difficult to read because it contains a mixed bag
of unrelated things: base buffer type, buffer implementations,
buffer resource factory, and client buffer.
Split each of these into their own file.

When the output doesn't support hardware cursors, these errors
will be printed. However, these errors are expected and we have a
proper fallback.

For each format and modifier, log supported usage. Log a
human-readable format/modifier string.

ec8b49c93f869010e360bec501d61c18089fbc61 calls subsurface_consider_map()
too early. Instead, call it after emitting new_subsurface signal to let
compositors receive a map event.

Same as the previous commit.

dac040f87fee1cfdd7660aa1786b0734d95e03a4 mistakenly renamed
xdg_surface_destroy listener, which was listening to *unmap* events, to
xdg_surface_unmap. The actual fix, however, is to listen to destroy
events. This fixes various crashes.

This makes it clearer that the wlr_xdg_toplevel cannot be NULL.

It's an unnecessary wrapper.

It seems it was forgotten to adjust when implementing
!3461 High-resolution scroll wheel support

No need to go back to the generic wlr_renderer/wlr_texture when
passing a Vulkan renderer/texture to an internal function.
|
|
We were checking whether any of the features was supported. We need
to check if all of them are.
This makes the check consistent with query_modifier_support() above.

We don't need to store the list of enabled extensions.
While at it, rename variables to be less confusing.

These are unused.

I think the second parameter of the function should be void* instead of
void **, because we use it as a right value in the function.

It returns a bool, not an int.

This was previously used by the X11 backend but is no longer required
since the previous commit.
|
|
All we can do to influence adaptive sync on the X11 backend is set the
_VARIABLE_REFRESH window property like mesa automatically does. We don't
have any control beyond that, so we set the state to enabled on creating
the output and never allow changing it (just like the Wayland backend).
|
|
Adaptive sync is effectively always enabled when using the Wayland
backend. This is not something we have control over, so we set the
state to enabled on creating the output and never allow changing it.
|
|
Previously, adaptive sync was just a hint and wouldn't make any
atomic commit fail if the backend didn't support it. The main reason
is wlr_output_test wasn't supported at the time.
Now that we have a way for compositors to test whether a change can
work, let's remove the exception for adaptive sync and convert it to
a regular output state field.
|
|
Now the function checks if the reference output belongs to the layout,
and returns NULL if it doesn't.

The render list should neither contain scene trees or null buffers.

If the first test in output_ensure_buffer() fails with modifiers we
replace the swapchain with a modifierless swapchain and try again.
However if that fails as well the output is currently stuck without
modifiers until the next modeset.
To fix this, destroy the modifierless swapchain if the test using it
fails. The next output_attach_back_buffer() call will create a swapchain
that allows modifiers when needed.

Originally, I thought that we could safely subtract opaque regions
from the background even if the black rect optimization was kicking in.
This is wrong because a scene node that isn't fully occluded will still
appear in the render list even if its partially under a black rect. We
need to make sure that while culling the background, we only consider
opaque regions that are also visible. This will fix the black rect
optimization with the background.

These asserts were broken in 4c1afb12 as new implementations were added
without updating the wl_resource_instance_of() calls.
|
|
Head/mode resources older than version 3 and lacking a release request
are intentionally leaked as this is the only way to fix the race.
