Update on what happened in WebKit in the week from December 1 to December 8.
In this edition of the periodical we have further advancements on the Temporal implementation, support for Vivante super-tiled format, and an adaptation of the DMA-BUF formats code to the Android port.
Cross-Port 🐱
JavaScriptCore 🐟
The built-in JavaScript/ECMAScript engine for WebKit, also known as JSC or SquirrelFish.
Implemented the toString, toJSON, and toLocaleString methods for PlainYearMonth objects in JavaScriptCore's implementation of Temporal.
Graphics 🖼️
BitmapTexture and TextureMapper were prepared to handle textures where the logical size (e.g. 100×100) differs from the allocated size (e.g. 128×128) due to alignment requirements. This allowed to add support for using memory-mapped GPU buffers in the Vivante super-tiled format available on i.MX platforms. Set WEBKIT_SKIA_USE_VIVANTE_SUPER_TILED_TILE_TEXTURES=1 to activate at runtime.
WPE WebKit 📟
WPE Platform API 🧩
New, modern platform API that supersedes usage of libwpe and WPE backends.
The WPEBufferDMABufFormats class has been renamed to WPEBufferFormats, as it can be used in situations where mechanisms other than DMA-BUF may be used for buffer sharing—on Android targets AHardwareBuffer is used instead, for example. The naming change involved also WPEBufferFormatsBuilder (renamed from WPEBufferDMABufFormatsBuilder), and methods and signals in other classes that use these types. Other than the renames, there is no change in functionality.
That’s all for this week!
