2023-12-05render/gles2: add wlr_gles2_renderer_get_buffer_fbo()Simon Ser
Replacement for wlr_gles2_renderer_get_current_fbo(). Wayfire uses it for instance.
2023-11-30renderer: Drop buffer bindingAlexander Orzechowski
2023-11-30render: Nuke old read pixels APIAlexander Orzechowski
Sadly, the new API is not backwards compatible with the old API. Since we have already switched all users in wlroots to the new API compositors are already practically mandated to implement the new API. Let's get rid of the old one since there is no point.
2023-11-30render: Implement texture_preferred_read_formatAlexander Orzechowski
2023-11-30render/gles2: Implement texture_read_pixelsAlexander Orzechowski
Also get rid of gles2_texture.owns_texture. We only use the tex/fbo
2023-11-30render/gles2: save/restore context when creating/submitting a render passSimon Ser
This is useful for e.g. lazily blitting a texture for readback purposes while rendering.
2023-11-30render/gles2: reword wlr_gles2_texture commentsSimon Ser
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().
2023-11-30render/gles2: Inline texture invalidationAlexander Orzechowski
Let's us share more code with the other code path
2023-11-30render/gles2: Don't attach texture as buffer addonAlexander Orzechowski
Since wlr_gles2_buffer is now managing importing for us, there is no reason for us to continue doing this.
2023-11-30render/gles2: Don't track image in textureAlexander Orzechowski
We can get it from the buffer
2023-11-30render/gles2: Don't double import dmabufAlexander Orzechowski
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
2023-11-30render/gles2: Destroy textures firstAlexander Orzechowski
Since imported textures will be based off of gles2_buffer we have to destroy textures first or else they will have an invalid reference to the buffers they are imported from.
2023-11-30renderer/gles2: Bail rendering to external buffers when binding themAlexander Orzechowski
We can't do it while we're creating them because we'll want to use gles2 buffers for textures soon.
2023-11-30render/gles2: Lazily create buffer fboAlexander Orzechowski
2023-11-29render/gles2: check external-only flag in get_or_create_buffer()Simon Ser
If the external-only flag is set, then the EGLImage is only supported for use with GL_TEXTURE_EXTERNAL_OES texture targets. In particular, the EGLImage cannot be bound to a RBO.
2023-11-29render/gles2: Don't track has_alpha in pixel_formatAlexander Orzechowski
Why track the alpha here when we can already get that information elsewhere?
2023-11-25Cleanup wlr_matrix.h includesSimon Ser
Many files used to require wlr_matrix but no longer do.
2023-11-23util/transform: move over wl_output_transform helpersSimon Ser
These aren't really tied to wlr_output.
2023-11-22render/gles2: drop legacy rendering APISimon Ser
2023-10-31Remove unnecessary codeJiDe Zhang
Not needs set GL_DEPTH_TEST, Because when rendering to a framebuffer that has no depth buffer, depth testing always behaves as though the test is disabled, The initial value for each capability with the exception of GL_DITHER is GL_FALSE.
2023-10-03treewide: Migrate from sizeof(struct) to sizeof(*pointer) where practicalAlexander Orzechowski
2023-09-21renderer: Use wlr_render_rect_options_get_boxAlexander Orzechowski
Fixes: #3697
2023-07-12render/gles2: wrap timer setup in push_gles2_debug()Simon Ser
With this, errors should be properly wrapped in the debug scope.
2023-07-11render: constify struct wlr_buffer_pass_optionsSimon Ser
Let's not allow renderer implementations to mutate the passed in options.
2023-07-11Use wl_container_of() instead of castsSimon Ser
This slightly improves type safety. The culprits were found with: git grep -E '\([a-z0-9_ ]+ \*\)\W?[a-z]'
2023-07-11render/gles2: drop unnecessary castSimon Ser
We can just refer to the struct field here.
2023-07-07Use struct initializers instead of memset()Simon Ser
This is a bit more type-safe.
2023-06-19render: Introduce wlr_render_texture_options.blend_modeAlexander Orzechowski
2023-06-19renderer: Introduce wlr_scale_filter_modeAlexander Orzechowski
2023-06-06render/gles2: Handle NULL timerAlexander Orzechowski
2023-06-05render/gles2: implement timer APIRose Hudson
2023-06-05add render timer APIRose Hudson
Based on five calls: wlr_render_timer_create - creates a timer which can be reused across frames on the same renderer wlr_renderer_begin_buffer_pass - now takes a timer so that backends can record when the rendering starts and finishes wlr_render_timer_get_time - should be called as late as possible so that queries can make their way back from the GPU wlr_render_timer_destroy - self-explanatory The timer is exposed as an opaque `struct wlr_render_timer` so that backends can store whatever they want in there.
2023-05-28renderer/gles2: Implement render pass interfaceAlexander Orzechowski
2023-05-28renderer/gles2: Compute texture coordinates based off of vertex positionsAlexander Orzechowski
2023-05-28renderer/gles2: Merge get_buffer and create_bufferAlexander Orzechowski
2023-05-28renderer/gles2: Interpret matrix as column major in shaderAlexander Orzechowski
Avoids us needing to transpose.
2023-05-21render/pixel-format: add support for block-based formatsSimon Ser
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.
2023-04-12render/gles2: use byte-aligned rows for glReadPixelsManuel Stoeckl
Setting the GLESv2 parameter GL_PACK_ALIGNMENT to 1 ensures that the stride of the glReadPixels output matches the value computed in `pack_stride`. Since the default value of GL_PACK_ALIGNMENT is 4, this does not make a difference under normal use; but without this patch the stride can be incorrect; for example, with RGB565 buffers and screenshots of regions with odd width.
2023-02-02render/gles2: default to highp if availableSimon Ser
The spec [1] says that the maximum value for a mediump float is at least 2¹⁴ in section 4.5.2. However, when using a 4k resolution texture coordinates will exceed this value. This causes issues on drivers which implement mediump as a 16-bit [2]. Switch to highp. There's a twist: on GLES2, support for highp is optional. So we need to guard it with cute GL_FRAGMENT_PRECISION_HIGH ifdefs.

2023-02-02render/gles2: use correct type for shader typeSimon Ser
Doesn't matter a lot, but let's try to be consistent with the GL headers.
2022-12-01wlr_texture: Expose owning rendererAlexander Orzechowski
2022-11-15render/pixel_format: import pixel_format_info_check_stride()Simon Ser
We'll use this function from wlr_shm too. Add some assertions, use int32_t (since the wire protocol uses that, and we don't want to use 16-bit integers on exotic systems) and switch the stride check to be overflow-safe.
2022-11-15render/gles2: query glGetGraphicsResetStatusKHRSimon Ser
Call glGetGraphicsResetStatusKHR in wlr_renderer_begin to figure out when a GPU reset occurs. Destroy the renderer when this happens (the OpenGL context is defunct).
2022-11-15render: allow wlr_renderer_impl.begin to failSimon Ser
Make it return a bool to indicate success/failure. Adapt the various implementations to check errors.
2022-11-11render/texture: constify wlr_texture_update_from_buffer()Simon Ser
2022-10-28render/gles2: de-duplicate vertex shadersSimon Ser
The vertex shaders for quads and textures are identical.
2022-10-28render/gles2: move color uniform from quad.vert to quad.fragSimon Ser
We have no use for a v_color varying. We can use the uniform directly from the fragment shader without getting the vertex shader involved.
2022-10-28render/gles2: move shaders to individual filesSimon Ser
Instead of having a C file with strings for each shader, move each shader into its own file. Use a small POSIX shell script to convert the files into C strings (can't wait for C23 #embed...). The benefits from this are: - Improved readability and syntax highlighting. - Line numbers in shader compiler errors are easier to make sense of. - Consistency with the Vulkan renderer. - Shaders will become more complicated as we add color management features.
2022-10-27render/gles2: log error on shader compilation failureSimon Ser
2022-10-10render/gles2: assert that GL_OES_EGL_image_external is supportedSimon Ser
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].
