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.

Saves us from walking a list.
2021-07-30render/gles2: add a few 10-bit and FP16 formatsManuel Stoeckl
The half-float formats depend on GL_OES_texture_half_float_linear, not just the GL_OES_texture_half_float extension, because the latter does not include support for linear magni/minification filters. The new 2101010 and 16161616F formats are only available on little- endian builds, since their gl_types are larger than a byte and thus endianness dependent.
2021-07-30render/gles2: hide shm formats without GL supportManuel Stoeckl
This change introduces a new function to check whether the renderer has the needed GL extensions to read a given pixel format.
2021-07-12render/gles2: rename wlr_egl.exts to better match KhronosSimon Ser
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.

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.

2021-03-10output: improve transform matrix calculationSimon Zeni
Compute only the transform matrix in the output. The projection matrix will be calculated inside the gles2 renderer when we start rendering. The goal is to help the pixman rendering process.

2020-07-28render/gles2: remove gles2_procsSimon Ser
Move the global into wlr_gles2_renderer. This removes global state and allows us to have multiple renderers with different GL loaders.

2020-07-28render/gles2: make wlr_gles2_texture_from_* privateSimon Ser
These functions are unused by compositors (see e.g. [1]) and prevent wlr_gles2_texture from accessing wlr_gles2_renderer state. This is an issue for proper teardown [2] and for accessing GLES2 extensions. [1]: https://github.com/swaywm/wlroots/pull/1962#issuecomment-569511830 [2]: https://github.com/swaywm/wlroots/pull/1962

Instead of requiring compositors to call wlr_texture_get_size each time they want to access the texture's size, expose this information as wlr_texture fields.

2019-12-20Refactor EGL/GL API loadingSimon Ser
Remove glapi.sh code generation, replace it with hand-written loading code that checks extension strings before calling eglGetProcAddress. The GLES2 renderer still uses global state because of: - {PUSH,POP}_GLES2_DEBUG macros - wlr_gles2_texture_from_* taking a wlr_egl instead of the renderer
2019-11-06render/gles: Simplify textures a bitScott Anderson
We don't need our own enum for types. Instead we just use GL_TEXTURE_{2D,EXTERNAL_OES}, which already describes usage. Also fixes a situation where we were using GL_TEXTURE_2D in a situation we should not have. wl_drm buffers are always GL_TEXTURE_EXTERNAL_OES, no matter if they're RGB or any other format.
2019-07-17Use -fmacro-prefix-map to strip build pathManuel Stoeckl
This commit matches sway's 2dc4978d8af326c310057ca8fd22a4c7f5d09335. To help ensure a reproducible build (when debug info is disabled), the meson build script now uses the -fmacro-prefix-map command line argument supported by GCC to strip the build-path dependent bytes of each __FILE__ string used by wlr_log and related functions. A rather ugly algorithm is used to compute the relative path between the build and source folders, because meson has no specific function for this. When the compiler does not support -fmacro-prefix-map, fall back to shifting the start of each __FILE__ string by the length of the relative path to the source directory.
2019-04-22Fix missing headers when building without X11Alyssa Ross
The deleted includes are redundant, because other headers will include the necessary files. Additionally, they cause build failures, because including EGL/egl.h or EGL/eglext.h directly, instead of through wlr/render/egl.h or wlr/render/interface.h, will mean that MESA_EGL_NO_X11_HEADERS will not have been defined, and so the EGL headers will attempt to pull in unnecessary X11 headers that may not exist on the system. For the headers produced by glgen.sh, the includes couldn't simply be deleted, because no other header would include the EGL headers. Neither wlr/render/egl.h or wlr/render/interface.h felt appropriate to include, so I opted instead to copy the MESA_EGL_NO_X11_HEADERS definition before the EGL includes.

2018-11-04render/gles2: remove assumptions about supported formatsemersion
We were assuming GL_BGRA_EXT was always supported. We now check that it's supported for rendering. We fail if it isn't because this format is specified as "always supported" by the Wayland protocol. We also check if it's supported for reading pixels. A new preferred_read_format function returns the preferred format that can be used to read pixels. This is used by the screencopy protocol.
