2024-02-15Define _POSIX_C_SOURCE globallySimon Ser
Stop trying to maintain a per-file _POSIX_C_SOURCE. Instead, require POSIX.1-2008 globally. A lot of core source files depend on that already. Some care must be taken on a few select files where we need a bit more than POSIX. Some files need XSI extensions (_XOPEN_SOURCE) and some files need BSD extensions (_DEFAULT_SOURCE). In both cases, these feature test macros imply _POSIX_C_SOURCE. Make sure to not define both these macros and _POSIX_C_SOURCE explicitly to avoid POSIX requirement conflicts (e.g. _POSIX_C_SOURCE says POSIX.1-2001 but _XOPEN_SOURCE says POSIX.1-2008). Additionally, there is one special case in render/vulkan/vulkan.c. That file needs major()/minor(), and these are system-specific. On FreeBSD, _POSIX_C_SOURCE hides system-specific symbols so we need to make sure it's not defined for this file. On Linux, we can explicitly include <sys/sysmacros.h> and ensure that apart from symbols defined there the file only uses POSIX toys.
2024-02-12Add more POSIX compliance macros to fix uClibc supportPaul Cercueil
- Add POSIX 1993.09 compliance macro in source files that use "struct timespec"; - Add POSIX 2001.12 compliance macro in source files that use "struct sigaction" and the SA_SIGINFO macro, or the fchmod() function; - Add POSIX 2008.09 compliance macro in source files that use the getline() function. These compliance macros are enough for wlroots to compile with the git-master version of uClibc-ng. Signed-off-by: Paul Cercueil <paul@crapouillou.net>
2024-01-31render/gles2: Fixup dropping has_alpha from pixel_formatLeo Li
Fixes: 71fb55f3 ("render/pixel-format: Move has_alpha into it's own array")
2024-01-31render/pixel-format: Move has_alpha into it's own arrayLeo Li
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.
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: 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
2023-11-29render/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.
2023-10-03treewide: Migrate from sizeof(struct) to sizeof(*pointer) where practicalAlexander Orzechowski
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]'
2023-07-07Use struct initializers instead of memset()Simon Ser
This is a bit more type-safe.
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.
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.
2022-11-11render/texture: constify wlr_texture_update_from_buffer()Simon Ser
2022-08-18Use wl_signal_emit_mutableAlexander Orzechowski
2022-08-12render: replace wlr_texture_write_pixels with update_from_bufferSimon Ser
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.
2022-06-16render/texture: drop wlr_texture_is_opaqueSimon Ser
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.
2022-05-07render/gles: add support for some 16-bpc unsigned shm formatsManuel Stoeckl
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.
2021-11-17Remove support for DMA-BUF flagsSimon Ser
They are never used in practice, which makes all of our flag handling effectively dead code. Also, APIs such as KMS don't provide a good way to deal with the flags. Let's just fail the DMA-BUF import when clients provide flags.
2021-09-15types/buffer: make {begin,end}_data_ptr_access part of the public APISimon Zeni
2021-09-10buffer: add data_ptr access flagsSimon Ser
This allows callers to specify the operations they'll perform on the returned data pointer. The motivations for this are: - The upcoming Linux MAP_NOSIGBUS flag may only be usable on read-only mappings. - gbm_bo_map with GBM_BO_TRANSFER_READ hurts performance.
2021-08-12render/gles2: make wlr_gles2_texture a wlr_buffer addonSimon Ser
2021-07-12render/gles2: set has_alpha for DMA-BUFsSimon Ser
Use our internal pixel format table to figure out whether an imported DMA-BUF has alpha.
2021-07-05render/gles2: use wlr_drm for wl_drm implementationSimon Ser
This allows use to remove all of our special wl_drm support code.
2021-07-01render: drop wlr_renderer_impl.texture_from_dmabufSimon Ser
2021-07-01render: drop wlr_renderer_impl.texture_from_pixelsSimon Ser
2021-06-24render/egl: make most functions privateSimon Ser
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.
2021-06-07render/gles2: add support for DATA_PTR buffers in texture_from_bufferSimon Ser
2021-05-30render/gles2: fix texture cleanup on destroySimon Ser
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
2021-05-17render/gles2: implement texture_from_bufferSimon Ser
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.
2021-05-17render/gles2: add gles2_texture_createSimon Ser
This centralizes the wlr_texture initialization. In future commits, more fields will need to get initialized.
2021-05-17render/gles2: remove unnecessary EGL import ext checksSimon Ser
We require the ext in the renderer init function.
2021-04-22render: remove NULL checks in wlr_texture_impl.destroySimon Ser
The NULL check already exists in wlr_texture_destroy, no need to duplicate it in each impl
2021-04-22render/gles2: destroy textures on renderer teardownSimon Ser
2021-04-15render/gles2: prevent imported DMA-BUF textures from being mutatedSimon Ser
The compositor shouldn't write to client buffers if the client attaches a DMA-BUF to a wl_surface, then attaches a shm buffer. Make gles2_texture_write_pixels return an error to prevent this from happening.
2021-04-08render: remove wlr_texture_to_dmabufSimon Ser
This is unused in wlroots, and the use-cases for compositors are pretty niche since they can access the original DMA-BUF via the wlr_buffer.
2021-03-25render/gles2: remove depth and bpp gles2_pixel_format, use drm pixel formatSimon Zeni
2021-02-23render: use DRM formats in wlr_texture_from_pixelsSimon Ser
2021-02-23render/gles2: replace wlr_gles2_texture.wl_format with drm_formatSimon Ser
2021-02-23render/gles2: convert format table to DRM formatsSimon Ser
2021-02-19render/gles2: check buffer stride when uploading textureSimon Ser
If the stride is too small, the driver could end up segfaulting (e.g. radeonsi segfaults in __memmove_sse2_unaligned_erms).
2021-02-05render/gles2: remove YUV blocklistSimon Ser
Mesa provides YUV shaders, and can import multi-planar YUV DMA-BUFs as a single EGLImage. Remove the arbitrary limitation. If the driver doesn't support importing YUV as a single EGLImage, the import will fail and the result will be the same anyways.
2021-02-01render/wlr_texture: clamp texture coordinates to edge by defaultQuantum
Clamping texture coordinates prevents OpenGL from blending the left and right edge (or top and bottom edge) when scaling textures with GL_LINEAR filtering. This prevents visual artifacts like swaywm/sway#5809. Per discussion on IRC, this behaviour is made default. Compositors that want the wrapping behaviour (e.g. for tiled patterns) can override this by doing: struct wlr_gles2_texture_attribs attribs; wlr_gles2_texture_get_attribs(texture, &attribs); glBindTexture(attribs.target, attribs.tex); glTexParameteri(attribs.target, GL_TEXTURE_WRAP_S, GL_REPEAT); glTexParameteri(attribs.target, GL_TEXTURE_WRAP_T, GL_REPEAT); glBindTexture(attribs.target, 0);
2021-01-15render/gles2: restore EGL context after texture operationsSimon Ser
It can be surprising and unexpected that texture operations (such as texture upload and import) change the current EGL context, especially when it's done under-the-hood by wlroots in response to wl_surface requests. To prevent surprises, save and restore the previous EGL context.
