A lot of protocols extend the wl_surface state. Such protocols need
to synchronize their extended state with wl_surface.commit and
cached states. Add a new utility for this purpose.
|
|
|
|
The function does not check whether the upload succeeded: it does
not check the wlr_client_buffer.
|
|
No need to store this bit, we can infer it from buffer_width and
buffer_height.
|
|
This allows compositors to check whether the cursor hint is set.
|
|
Allows compositors to figure out whether a DRM backend is
secondary on a multi-GPU setup.
|
|
This is similar to wlr_pixman_texture_get_image and can be useful for
compositors to access the rendering data.
|
|
Replacement for wlr_gles2_renderer_get_current_fbo(). Wayfire uses
it for instance.
|
|
This is unused.

This is the last of a set of commits which ensures that both textures
and render buffers can be accessed through _UNORM and _SRGB image
views. While _UNORM image views are not yet used for 8-bpc image
formats, they will be needed in the future to support color transforms
for both textures and render buffers.
|
|
|
|
|
|
Later commits will start using _SRGB image views again,
where appropriate.

|
The damage ring is only supposed to keep track of damage within
the swapchain

Sadly, the new API is not backwards compatible with the old API. Since
we have already switched all users in wlroots to the new API compositors
are already practically mandated to implement the new API. Let's get rid
of the old one since there is no point.
|
|
|
|
|
|
Also get rid of gles2_texture.owns_texture. We only use the tex/fbo
|
|
|
|
|
|
This scales better when more render pass options are added.
|
|
This is useful for e.g. lazily blitting a texture for readback
purposes while rendering.
|
|
|
|
It turns out we forgot about the function declaration in the header.
Also some docs were still referring to that function.
Move the wlr_output_attach_render() docs to
wlr_output_begin_render_pass().

These comments were a bit misleading:
- "GL_TEXTURE_2D == mutable": not really, imported non-external-only
DMA-BUFs would also use this target, but are not mutable.
- "Only affects target == GL_TEXTURE_2D": same here.
- "If imported from a wlr_buffer": not really, would be NULL if
imported from a shm wlr_buffer.
Adjust these comments to better reflect reality and adjust the check
in gles2_texture_update_from_buffer().
|
|
Since wlr_gles2_buffer is now managing importing for us, there is
no reason for us to continue doing this.
|
|
We can get it from the buffer
|
|
We can double import a dmabuf if we use it as a texture target and
a render target. Instead, let's unify render targets and texture dmabuf
imports to use wlr_gles2_buffer which manages the EGLImageKHR
|
|
We can't do it while we're creating them because we'll want to use
gles2 buffers for textures soon.
|
|
|
|
This is unused.
|
|
This function touches queued_fb/current_fb, which the renderer has
nothing to do with.
|
|
|
|
This is always true now that we can only render with a buffer.
|
|
|
|
|
|
|
|
This adds an alternate way to use wlr_damage_ring without the
concept of buffer age. Buffer age is a concept inherited from EGL
but there is no real reason why we should continue to use that in
wlroots. Instead, use wlr_buffer pointers.
Eventually, we should be able to remove the buffer age based
functions.
|
|
Why track the alpha here when we can already get that information
elsewhere?
|
|
This was used by the legacy rendering API. Since begin()/end()
only need to set current_render_buffer and nothing else, we can
drop all of these bits.
|
|
Under X11, ConfigureNotify means that the window has already been resized.
Sending ConfigureRequest with the received size is not only useless, but also
can confuse the window manager, which will probably reply with the current
(i.e. *old*) size causing a configure loop.

new_subsurface emitted immediately isn't actually that useful. Revert the change
and document that this event is special.
This reverts commit 504b9491f05d3227d45ea6bcc9c347e1a6bf9586.

|
Compositors should no longer need matrix operations to render:
the old rendering API has been removed, and the new API doesn't
take matrices as input.
|
|
The only function in that header is now also declared in
wlr/types/wlr_compositor.h.
