The target is set to GL_TEXTURE_EXTERNAL_OES when
EGL_EXT_image_dma_buf_import_modifiers [1] returns an external_only
flag. That spec states:
> In order to support imports for the GL_TEXTURE_EXTERNAL_OES target, a
> compatible OpenGL ES implementation supporting GL_OES_EGL_image_external
> must be present.
Fail hearder when a driver doesn't follow the spec instead of
skipping rendering.
See [2].

Simplify things a bit.

In the CREATE_DUMB error code-path, we'd only free() the buffer,
however it's already inserted in the alloc->buffers list at this
point.
Instead, make sure finish_buffer() is safe to call (by populating
drm_fd) and call that function.

|
Simplifies error handling a bit.
|
|
Check that the modifier list passed as input contains either
INVALID or LINEAR. We don't support others.
|
|
INVALID means that the modifier is implicit. However dumb buffers
are guaranteed to be LINEAR, so let's just advertise this. Fixes
cursors with the DRM backend: cursor planes usually only support
LINEAR.
|
|
When running with the DRM backend, the Pixman renderer needs to
render the cursor buffer. However, DRM drivers only support linear
buffers for these in general, they don't support implicit modifiers
(aka. INVALID).
Advertise support for LINEAR in the Pixman renderer to fix this.
|
|
If we have a render node, it means there is a GPU which could be
used. We probably failed GL because of a kernel or Mesa issue.
Instead of automatically falling back to Pixman, error out.
This makes it more obvious to users when something goes wrong,
instead of silently exposing a slow unaccelerated desktop.

The Vulkan renderer is still experimental. If GL fails, we don't
want to automatically fall back to it by default.

Avoids having to walk the list of all textures.

Avoids having to walk the list containing all of the render buffers.

The function returns -1 if it doesn't find a suitable memory type.

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.

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

This lets the renderer handle the wlr_buffer directly, just like it
does in texture_from_buffer. This also allows the renderer to batch
the rectangle updates, and update more than the damage region if
desirable (e.g. too many rects), so can be more efficient.
|
|
GL_ALPHA_BITS is the number of bits of the alpha channel of the
currently bound frame buffer's color buffer -- which is precisely
renderer->current_buffer->rbo . Thus, instead of binding the color
buffer and checking its properties, we can query the already bound
frame buffer.
Note that GL_IMPLEMENTATION_COLOR_READ_{FORMAT,TYPE} are also
properties of frame buffer's color buffer.

Instead of checking whether the wlr_egl dependencies are available
in the GLES2 code, introduce internal_features['egl'] and check
that field.
When updating the EGL dependency list, we no longer need to update
the GLES2 logic.
|
|
The GLES2 renderer depends on EGL, which depends on GBM for device
selection.
|
|
Whether a texture is opaque or not doesn't depend on the renderer
at all, it just depends on the source buffer. Instead of forcing
all renderers to implement wlr_texture_impl.is_opaque, let's move
this in common code and use the wlr_buffer format to know whether
a texture will be opaque.

`vulkan_format_props_query` calls `query_modifier_support` which
initializes fields of `props` with allocated memory. this memory is
leaked if `query_modifier_support` does not find a supported format
and shmtex is not supported, as in this case `add_fmt_props` ends
up being false and the allocated fields of `props` are never freed.
|
|
69477051ccff ("matrix: deprecate wlr_matrix_projection") marked it
as deprecated. 1 year later, we can now remove it from our public
API.
|
|
Instead of computing the projection, then flipping, just provide
the correct transform to wlr_matrix_projection().
|
|
|
|
Replace them with wlr_signal_emit_safe, which correctly handles
cases where a listener removes another listener.

Now that the DRM backend no longer depends on GBM, we can make it
optional. The GLES2 renderer still depends on it because of our EGL
device selection.
This is useful for compositors with their own renderers, and for
compositors using the Vulkan renderer.
|
|
This allows compositors to integrate with the wlroots GLES2
renderer, if they need to perform custom GL rendering.
|
|
These formats require EXT_texture_norm16, which in turn needs OpenGL
ES 3.1. The EXT_texture_norm16 extension does not support passing
gl_internalformat = GL_RGBA to glTexImage2D, as can be done for
formats available in OpenGL ES 2.0, so this commit adds a field to
wlr_gles2_pixel_format to provide a more specific internalformat
parameter to glTexImage2D.
|
|
Added the implement of wlr_texture_is_vk.

Ensures there is no field left to its previous undefined value after
