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.

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.
|
|
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.
|
|
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.
|
|
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.
|
|
|
|
Replace it with wlr_egl.dmabuf_render_formats.
|
|
Rename wlr_renderer_get_dmabuf_formats to
wlr_renderer_get_dmabuf_texture_formats. This makes it clear the formats
are only suitable for creating wlr_textures.
|
|
It describes which DMA-BUF formats can be used to render.
|
|
Make it clear formats returned are only suitable for import/sampling.
These formats can't be used to be rendered to.

This is a Mesa-specific header that was needed because some Wayland EGL
extensions were missing from the Khronos registry. Now that this has
been fixed [1] and Mesa [2] & glvnd [3] have sync'ed their headers, we
can drop this workaround.

This avoids Xlib.h inclusion via EGL headers. See [1] for discussion.
This change is based on a Weston commit [2].

EGL_EXT_image_dma_buf_import_modifiers tells us whether we should use
GL_TEXTURE_2D or GL_TEXTURE_EXTERNAL_OES. Using the right texture target
can fix some failures and/or improve performance on some drivers.
This does the same as a Weston commit [1].

This function can be called after wlr_egl_make_current to cleanup the
EGL context. This avoids having lingering EGL contexts that make things
work by chance.

This patch will make the EGL renderer work on any EGL/GLESv2 driver
providing the EGL_WL_bind_wayland_display extensions.
Mesa used to declare provisional EGL_WL_bind_wayland_display directly
in <EGL/eglext.h>. Then, all unofficial extensions were moved to
<EGL/eglmesaext.h>, to have a cleaner implementation. See:
https://gitlab.freedesktop.org/mesa/mesa/-/commit/ab7bb10a2af711086319ce35815acd797b86fe27
The extension was then approved at Khronos Group, and reached the
official <EGL/eglext.h>. See:
https://www.khronos.org/registry/EGL/extensions/WL/EGL_WL_bind_wayland_display.txt
https://github.com/KhronosGroup/EGL-Registry/commit/aa9b63f3ab18aee92c95786a2478156430f809e4
In order to make sure the renderer will work on any version of any
implementation providing the extension, only include the mesa-specific
header if it's present.

wlr_egl_init is not allowed to mutate these attribs.
|
|
Even if the X11 backend or Xwayland is enabled, we don't rely on
EGL/egl.h including Xlib headers.
|
|
Remove glapi.sh code generation, replace it with hand-written loading
code that checks extension strings before calling eglGetProcAddress.
The GLES2 renderer still uses global state because of:
- {PUSH,POP}_GLES2_DEBUG macros
- wlr_gles2_texture_from_* taking a wlr_egl instead of the renderer
|
|
Define both MESA_EGL_NO_X11_HEADERS and EGL_NO_X11 for
backward combatibility.

The documentation for wayland-server.h says:
> Use of this header file is discouraged. Prefer including
> wayland-server-core.h instead, which does not include the server protocol
> header and as such only defines the library PI, excluding the deprecated API
> below.
Replacing wayland-server.h with wayland-server-core.h allows us to drop the
WL_HIDE_DEPRECATED declaration.

This prevents some annoying issues when e.g. not including wlr/config.h or
making a typo in the guard name.
|
|
If no X11 related things are being built, tell Mesa's eglplatform.h not to attempt inclusion of associated X11 header.

This introduces -DWLR_USE_UNSTABLE and adds information regarding the
stability status to all headers. I started with a conservative set of
headers to mark as stable:
- types/wlr_matrix.h
- util/edges.h
- util/log.h
- util/region.h
- xcursor.h

Detecting whether eglSwapBuffersWithDamageEXT or
eglSwapBuffersWithDamageKHR is used should be based on the extension
string, not only on the availability of the function.

It's possible to implement it outside the renderer, by creating a
texture and destroying it right away. This reduces the API surface
of the renderer.
