This is unused.
|
|
This is no longer used.
|
|
Saving the old context and immediately making our own context
current is a common pattern. Let's make it easier to do.
No functional change, just refactoring.
|
|
Since we only use the backend capabilities here we can simply pass
them in directly. This allows other locations to create an allocator
even if they don't have a backend. They can simply specify the caps
they want instead.

Some opaque pixel formats (nv12, p010) require per-plane bytes_per_block
info. However, it doesn't make sense to store them in
wlr_pixel_format_info, as they will never be useful (currently, this
info is used for shm, which doesn't have a concept of multi-planar
buffers.)
Let's define a separate array and function for determining whether a
pixel format has alpha.

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.

Also get rid of gles2_texture.owns_texture. We only use the tex/fbo
|
|
This is useful for e.g. lazily blitting a texture for readback
purposes while rendering.

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.
|
|
|
|
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.
|
|
All built-in renderers now implement the new API.
|
|
This commit only applies to the render pass API.
|
|
|
|
The flags passed to vkCreateImage() must match the flags used when
querying formats. Make this clearer by using the same variable.
|
|
|
|
Now that we are dynamically creating pipeline layouts, we need separate
texture views for each pipeline layout we choose to use with a texture.
|
|
These will happen lazily when pipelines get created.
|
|
This will become necessary when we switch away from scissoring. For the
time being, this cleans things up a bit and allows for a trivial
blending implementation for textures when that comes.
|
|
|
|
If we ever wanted to handle dynamic state that requires new pipelines
such as using different texture filters those can be added here with more
ease.

Will make it easier to add more pipeline layouts for other YCbCr
formats.
|
|
This will make it easier to create one pipeline layout (plus related
objects) per YCbCr format.
|
|
Some formats like sub-sampled YCbCr use a block of bytes to
store the color values for more than one pixel. Update our format
table to be able to handle such formats.

This is implemented by a two-subpass rendering scheme; the first
subpass draws (and blends) onto a linear R16G16B16A16_SFLOAT buffer,
while the second subpass performs linear->srgb conversion, writing
onto the actual output buffer.
|
|
Now it takes a reference to a destination format
|
|
|
|
|
|
|
|
|
|
This simplifies the vkQueueSubmit call, removing the need to pass
timeline semaphore point values as separate arrays.
