- Textures are now immutable (apart from those created from raw
pixels), no more invalid textures
- Move all wl_drm stuff in wlr_renderer
- Most of wlr_texture fields are now private
- Remove some duplicated DMA-BUF code in the DRM backend
- Add more assertions
- Stride is now always given as bytes rather than pixels
- Drop wl_shm functions
Fun fact: this patch has been written 10,000 meters up in the air.
By using the same vertex shader and adding alpha to the fragment shader
for external textures we can:
- use alpha blending
- have wlr_gles2_render_texture_with_matrix work with
the GL_TEXTURE_EXTERNAL_OES. So far this failed
since we passed in alpha which was unknown by fragment_src_external
Allow to set the texture target type when generating/binding the
texture. This allows us to attach the texture type to the texture so we
don't have to keep the logic elsewhere.
Tested with
./weston-simple-dmabuf-drm
./weston-simple-dmabuf-drm --import-immediate=1
./weston-simple-dmabuf-drm --y-inverted=1
(and combinations)
Supports only single plane XRGB dmabufs for now.
This backports some changes to #319 to fix the screenshooter data
format. This also adds wlr_backend_get_renderer which will be
useful to support multiple renderers.
Since wlroots shaders only use one texture at a time (ie there is only one
sampler2D variable in any shader), it is unnecessary to switch between active
texture units at this time.
Add a signal for wlr_surface destruction on the wlr_surface that compositors
can listen to to remove the surface from their state.
Implement a listener for this in the example wl_compositor to remove the
surface from its internal list of surfaces.
Destroy the surface in the compositor destroy_surface callback given when the
surface resource was created.
Add a reference to the surface resource to the wlr_surface so a compositor can
find it in its list of resources upon wlr_resource destruction.
Implement surface_attach method. This is called when a client attaches an shm
buffer with wl_surface_attach().
Implement the GLES2 interface for attaching shm buffers. This creates an opengl
texture with the shm buffer contents for the surface.
This commit also includes some working code to render the surfaces onto the
screen for demonstration purposes.
