This EGL extension has been added in [1]. The upsides are:
- We directly get a render node, instead of having to convert the
primary node name to a render node name.
- If EGL_DRM_RENDER_NODE_FILE_EXT returns NULL, that means there is
no render node being used by the driver.

Now that we have our own wl_drm implementation, there's no reason
to provide custom renderer hooks to init a wl_display in the
interface. We can just initialize the wl_display generically,
depending on the renderer capabilities.
|
|
Khronos refers to extensions with their namespace as a prefix in
uppercase. Change our naming to align with Khronos conventions.
This also makes grepping easier.
|
|
|
|
Our GLES2 renderer doesn't use it anymore, so we can drop it.
|
|
Everything needs to go through the unified wlr_buffer interface
now.
If necessary, there are two ways support for
EGL_WL_bind_wayland_display could be restored by compositors:
- Either by using GBM to convert back EGL Wayland buffers to
DMA-BUFs, then wrap the DMA-BUF into a wlr_buffer.
- Or by wrapping the EGL Wayland buffer into a special wlr_buffer
that doesn't implement any wlr_buffer_impl hook, and special-case
that buffer type in the renderer.

The wlr_egl functions are mostly used internally by the GLES2
renderer. Let's reduce our API surface a bit by hiding them. If
there are good use-cases for one of these, we can always make them
public again.
The functions mutating the current EGL context are not made private
because e.g. Wayfire uses them.
|
|
This function has been removed, but we forgot to drop it from the
header.
|
|
Add wlr_pixman_buffer_get_current_image for wlr_pixman_renderer.
Add wlr_gles2_buffer_get_current_fbo for wlr_gles2_renderer.
Allow get the FBO/pixman_image_t, the compositor can be add some
action for FBO(for eg, attach a depth buffer), or without pixman
render to pixman_image_t(for eg, use QPainter of Qt instead of pixman).
|
|
Add the following functions:
- wlr_renderer_is_pixman
- wlr_texture_is_pixman
- wlr_pixman_texture_get_image
|
|
Export the interface used to determine whether the wlr_renderer object
is gles2.
|
|
The types of buffers supported by the renderer might depend on the
renderer's instance. For instance, a renderer might only support
DMA-BUFs if the necessary EGL extensions are available.
Pass the wlr_renderer to get_buffer_caps so that the renderer can
perform such checks.
Fixes: 982498fab3c4 ("render: introduce renderer_get_render_buffer_caps")

This allows compositors to choose a wlr_buffer to render to. This
is a less awkward interface than having to call bind_buffer() before
and after begin() and end().
Closes: https://github.com/swaywm/wlroots/issues/2618

This adds a a function to create a wlr_texture from a wlr_buffer.
The main motivation for this is to allow the renderer to create a
single wlr_texture per wlr_buffer. This can avoid needless imports
by re-using existing textures.
|
|
Users can just access the width/height fields directly.

|
For anything more complicated than quads, compositors can easily
ship their own shaders.
Closes: https://github.com/swaywm/wlroots/issues/2759
|
|
This is unused in wlroots, and the use-cases for compositors are
pretty niche since they can access the original DMA-BUF via the
wlr_buffer.
|
|
It can be replaced with wlr_renderer_bind_buffer. blit_dmabuf is
broken as-is (dies on an assertion).

Breaking changes:
Both "EGLint *config_attribs" and "wlr_egl->config" no longer exist.
|
|
Breaking changes:
wlr_egl_create_surface and wlr_egl_destroy_surface have been
removed and no longer exist.

These aren't used anymore.

This ensures wlr_gles2_renderer can properly take ownership of the
wlr_egl.

Nobody uses it anymore.
|
|
|
|
KHR is more "core" than EXT.
|
|
|
|
|
|
|
|
This isn't used anymore by any backend.
Some examples still provide an EGL config to wlr_egl_init, so we can't
drop it yet there.
|
|
Replace it with wlr_egl.dmabuf_render_formats.
