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.
|
|
We don't always need to enable blending: when the texture doesn't
have alpha or when the color is opaque, we can disable it.
|
|
Use our internal pixel format table to figure out whether an
imported DMA-BUF has alpha.

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.

A texture is opaque when it does *not* have alpha.

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.
|
|
This allows use to remove all of our special wl_drm support code.
|
|
Custom backends and renderers need to implement
wlr_backend_impl.get_buffer_caps and
wlr_renderer_impl.get_render_buffer_caps. They can't if enum
wlr_buffer_cap isn't made public.

We never create an EGL context with the platform set to something
other than EGL_PLATFORM_GBM_KHR. Let's simplify wlr_egl_create by
taking a DRM FD instead of a (platform, remote_display) tuple.
This hides the internal details of creating an EGL context for a
specific device. This will allow us to transparently use the device
platform [1] when the time comes.

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.
|
|
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.

Make it clear this function is a private wlroots API and will stay
that way.
|
|
|
|
|
|
This new API allows buffer implementations to know when a user is
actively accessing the buffer's underlying storage. This is
important for the upcoming client-backed wlr_buffer implementation.
|
|
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 probably already felt apart, but let's make it explicit that
this is not allowed.
|
|
This allows users to know the capabilities of the buffers that
will be allocated. The buffer capability is important to
know when negotiating buffer formats.
|
|
If we aren't the DRM master, allocating dumb buffers will fail with
EPERM.
|
|
When importing a DMA-BUF wlr_buffer as a wlr_texture, the GLES2
renderer caches the result, in case the buffer is used for texturing
again in the future. When the wlr_texture is destroyed by the caller,
the wlr_buffer is unref'ed, but the wlr_gles2_texture is kept around.
This is fine because wlr_gles2_texture listens for wlr_buffer's destroy
event to avoid any use-after-free.
However, with this logic wlr_texture_destroy doesn't "really" destroy
the wlr_gles2_texture. It just decrements the wlr_buffer ref'count.
Each wlr_texture_destroy call must have a matching prior
wlr_texture_create_from_buffer call or the ref'counting will go south.
Wehn destroying the renderer, we don't want to decrement any wlr_buffer
ref'count. Instead, we want to go through any cached wlr_gles2_texture
and destroy our GL state. So instead of calling wlr_texture_destroy, we
need to call our internal gles2_texture_destroy function.
Closes: https://github.com/swaywm/wlroots/issues/2941

Some formats have a byte-per-pixel lower than 1. Let's not encode
an arbitrary limitation into the wlr_renderer API.
|
|
When the matrix doesn't have a rotation, we can avoid a sqrt() call.
Tested with Sway's tabbed containers.
|
|
See [1]. This allows us to remove the workaround for GBM API
limitations.

Make it so wlr_gles2_texture is ref'counted (via wlr_buffer). This
is similar to wlr_gles2_buffer or wlr_drm_fb work.
When creating a wlr_texture from a wlr_buffer, first check if we
already have a texture for the buffer. If so, increase the
wlr_buffer ref'count and make sure any changes made by an external
process are made visible (by invalidating the texture).
When destroying a wlr_texture created from a wlr_buffer, decrease
the ref'count, but keep the wlr_texture around in case the caller
uses it again. When the wlr_buffer is destroyed, cleanup the
wlr_texture.
|
|
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.
|
|
This centralizes the wlr_texture initialization.
In future commits, more fields will need to get initialized.
|
|
We require the ext in the renderer init function.
|
|
Users can just access the width/height fields directly.

GL_RENDERER typically displays a human-readable string for the name
of the GPU, and EGL_VENDOR typically displays a human-readable string
for the GPU manufacturer. EGL_DRIVER_NAME_EXT should give the name of
the driver in use.

Rendering a wlr_texture with a different wlr_renderer is invalid.
Add an assert to make sure this doesn't happen.
|
|
Same as wlr_allocator_autocreate, but allows the caller to force a
DRM FD.
Similar to renderer_autocreate_with_drm_fd.
|
|
This function is only required because the DRM backend still needs
to perform multi-GPU magic under-the-hood. Remove the wlr_ prefix
to make it clear it's not a candidate for being made public.
|
|
Makes it easier to figure out why a backend/renderer is picked.
